Hi I'm trying to compile stunnel 4.08 on windows using mingw, with openssl-0.9.7f. I have edited the Makefile.w32 and it compiles ok until it cannot find the "-lssl". Any suggestions are welcome. //Olle ************************************** $ make -f Makefile.w32 stunnel.exe gcc -g -O2 -Wall -DUSE_WIN32 -DHAVE_OPENSSL -I/c/openssl/include -c -o stunnel.o stunnel.c gcc -g -O2 -Wall -DUSE_WIN32 -DHAVE_OPENSSL -I/c/openssl/include -c -o ssl.o ssl.c gcc -g -O2 -Wall -DUSE_WIN32 -DHAVE_OPENSSL -I/c/openssl/include -c -o client.o client.c gcc -g -O2 -Wall -DUSE_WIN32 -DHAVE_OPENSSL -I/c/openssl/include -c -o protocol.o protocol.c gcc -g -O2 -Wall -DUSE_WIN32 -DHAVE_OPENSSL -I/c/openssl/include -c -o sthreads.o sthreads.c gcc -g -O2 -Wall -DUSE_WIN32 -DHAVE_OPENSSL -I/c/openssl/include -c -o log.o log.c gcc -g -O2 -Wall -DUSE_WIN32 -DHAVE_OPENSSL -I/c/openssl/include -c -o options.o options.c gcc -g -O2 -Wall -DUSE_WIN32 -DHAVE_OPENSSL -I/c/openssl/include -c -o network.o network.c gcc -g -O2 -Wall -DUSE_WIN32 -DHAVE_OPENSSL -I/c/openssl/include -c -o resolver.o resolver.c gcc -g -O2 -Wall -DUSE_WIN32 -DHAVE_OPENSSL -I/c/openssl/include -c -o gui.o gui.c gcc -s -o stunnel.exe stunnel.o ssl.o client.o protocol.o sthreads.o log.o options.o network.o resolver.o gui.o resources.o -L/c/openssl/bin -lwsock32 -lgdi32 -lssl -mwindows c:\mingw\bin\..\lib\gcc-lib\mingw32\3.2.3\..\..\..\..\mingw32\bin\ld.exe: cannot find -lssl make: *** [stunnel.exe] Error 1 My Makefile.w32 ******************* SSLDIR=/c/openssl DEFINES=-DUSE_WIN32 -DHAVE_OPENSSL CFLAGS=-g -O2 -Wall $(DEFINES) -I$(SSLDIR)/include LDFLAGS=-s # LIBS=-L$(SSLDIR)/out -lssl -lcrypto -lwsock32 -lgdi32 LIBS=-L$(SSLDIR)/bin -lwsock32 -lgdi32 -lssl OBJS=stunnel.o ssl.o client.o protocol.o sthreads.o log.o options.o network.o resolver.o gui.o resources.o stunnel.exe: $(OBJS) $(CC) $(LDFLAGS) -o stunnel.exe $(OBJS) $(LIBS) -mwindows clean: rm *.o rm stunnel.exe #resources.o: resources.rc resources.h # windres resource.rc resources.o $(OBJS): *.h Makefile.w32 *********************

Hi, is there a way, under win32, to have stunnel reload its .conf file and certificates without restarting the service ? (A kind of SIGHUP) Thanks, Phil

Stunnel and CRLs
by CIM Massy 05 Apr '05

05 Apr '05

Hi, is there a way to automagically mutually verify certificates (verify=3) and to check the certificates against a .crl file hosted on a web server ? I want my "VNC over Stunnel" host check if the incoming connexions are authorized or if the certificates have expired / been revoked. Thanks, Phil

stunnel 4.09 problem: Connection rejected: too many clients
by Steven Van Acker 04 Apr '05

04 Apr '05

Hi, after upgrading to stunnel 4.09, we are having 2 problems with it that did not exist in a previous version (our case: stunnel 4.05 without pthreads) ---[ My testsetup is as follows: * stunnel listening on port 4321, connects to localhost port 13 (daytime) * daytime is enabled in inetd * stunnel was compiled without pthreads * ulimit -u = 8192 ---[ problem 1 At first, it works fine. For every incoming connection, the process forks and data is transferred. However, when the connection is closed, the forked process remains hanging for a while (about 1 minute) and then exits. This in itself is not a real problem, except that it generates a lot of processes. (and maybe causes problem 2 ?) ---[ data and logs concerning problem 1 (process hangs for 1 minute): I run the following command: openssl s_client -connect 192.168.2.119:4321 the output follows immediately The logfile (debug = debug) looks like this: 2005.03.31 14:05:05 LOG7[4552:0]: daytime accepted FD=8 from 192.168.2.103:47200 2005.03.31 14:05:05 LOG7[4552:0]: FD 8 in non-blocking mode 2005.03.31 14:05:05 LOG7[4553:0]: daytime started 2005.03.31 14:05:05 LOG5[4553:0]: daytime connected from 192.168.2.103:47200 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): before/accept initialization 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 read client hello A 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 write server hello A 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 write certificate A 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 write server done A 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 flush data 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 read client key exchange A 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 read finished A 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 write change cipher spec A 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 write finished A 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 flush data 2005.03.31 14:05:05 LOG7[4553:0]: 1 items in the session cache 2005.03.31 14:05:05 LOG7[4553:0]: 0 client connects (SSL_connect()) 2005.03.31 14:05:05 LOG7[4553:0]: 0 client connects that finished 2005.03.31 14:05:05 LOG7[4553:0]: 0 client renegotiatations requested 2005.03.31 14:05:05 LOG7[4553:0]: 1 server connects (SSL_accept()) 2005.03.31 14:05:05 LOG7[4553:0]: 1 server connects that finished 2005.03.31 14:05:05 LOG7[4553:0]: 0 server renegotiatiations requested 2005.03.31 14:05:05 LOG7[4553:0]: 0 session cache hits 2005.03.31 14:05:05 LOG7[4553:0]: 0 session cache misses 2005.03.31 14:05:05 LOG7[4553:0]: 0 session cache timeouts 2005.03.31 14:05:05 LOG6[4553:0]: SSL accepted: new session negotiated 2005.03.31 14:05:05 LOG6[4553:0]: Negotiated ciphers: RC4-SHA SSLv3 Kx=RSA Au=RSA Enc=RC4(128) Mac=SHA1 2005.03.31 14:05:05 LOG7[4553:0]: FD 7 in non-blocking mode 2005.03.31 14:05:05 LOG7[4553:0]: daytime connecting 127.0.0.1:13 2005.03.31 14:05:05 LOG7[4553:0]: connect_wait: waiting 10 seconds 2005.03.31 14:05:05 LOG7[4553:0]: connect_wait: connected 2005.03.31 14:05:05 LOG7[4553:0]: Remote FD=7 initialized 2005.03.31 14:05:05 LOG7[4553:0]: Socket closed on read 2005.03.31 14:05:05 LOG7[4553:0]: SSL write shutdown 2005.03.31 14:05:05 LOG7[4553:0]: SSL alert (write): warning: close notify 2005.03.31 14:05:05 LOG7[4553:0]: SSL_shutdown retrying 2005.03.31 14:05:06 LOG7[4553:0]: SSL alert (read): warning: close notify 2005.03.31 14:05:06 LOG7[4553:0]: SSL closed on SSL_read 2005.03.31 14:05:06 LOG7[4553:0]: Socket write shutdown When I check netstat, the connection from the client to stunnel is in the CLOSE_WAIT state and the connection from stunnel to the daytime server is in TIME_WAIT state then 1 minute later, this follows: 2005.03.31 14:06:06 LOG6[4553:0]: s_poll_wait timeout: connection close 2005.03.31 14:06:06 LOG5[4553:0]: Connection closed: 26 bytes sent to SSL, 0 bytes sent to socket 2005.03.31 14:06:06 LOG7[4553:0]: removing pid file /stunnel.pid 2005.03.31 14:06:06 LOG7[4552:0]: Steven: going into client_status with num_clients = 1 2005.03.31 14:06:06 LOG7[4552:0]: Process 4553 finished with code 0 (0 left) Now, netstat no longer shows the connections in any state. ---[ problem 2 Another problem that was found is that after bombarding stunnel with lots of connections, it stops accepting new connections. This would be normal if all connections remained open, but they are all closed. This is the error: Mar 31 13:53:40 hostname stunnel[13044]: Connection rejected: too many clients (>=4000) netstat only shows +- 500 connections, of which none are aimed at the stunnel process in question (port 4321 in my test setup) there is only 1 stunnel process active aswell. I dug into the problem a bit and it probably has to do with num_clients not being decreased after a process is closed (although I can not find any specifics :/) greets, -- Steven

Terminal services and stunnel 4.09
by Mattias Olsson 01 Apr '05

Hi! Im tying to access an internal Win2003 terminal server from my Linux box (internet). As i understand it stunnel should do the work. I have read some documents but im not sure... This is my setup. Linuxbox ----> Linuxbox ssh server | Firewall | Terminal server i wish to access. Can this be done or do i have to open a port in the fw to access the TS directly? Should stunnel.conf look like this on my linuxbox (client) cert = /usr/local/etc/stunnel/mail.pem client = yes On the TS? [TS] accept = 3000 connect = 3389 Should it have cert = ? Or could i on my linux ssh server have a config looking like this: [TS-remote] accept = 3000 connect = <internal-ip>:3389 Should it have cert = ? A novice man sends his best regards and thanks! /Kaz -- Mvh / Regards Mattias Olsson - aka - KaZaMaNIaC

Does stunnel work on Windows 2000 & SIMP(Secure Instant Messaging) ??
by DK 01 Apr '05

01 Apr '05

Hi Group, I have a windows 2000 box & want to communicate securely with someone else via SIMP(Secure Instant Messaging Protocol - http://www.winfosec.com/simp.php) I know that SIMP Instant Messaging is a "Direct Connection" & does NOT go through an intermediary server & that its encrypted, but being the security nut I am, I want to know if "stunnel" handles the SIMP protocols ? ... as I can't find anywhere what the SIMP protocols are ... because as I have read in the stunnel FAQ, stunnel does not handle UDP.

Hi Mike, Thank you for your precious help. I am using stunnel as SSL client. The SSL server runs in a router. As you suggested me, I have done these changes: at first I have modified the stunnel.conf with options = SSL_OP_TLS_BLOCK_PADDING_BUG stunnel.conf ============================== client = yes debug=7 options = SSL_OP_TLS_BLOCK_PADDING_BUG [telnet] accept = 23 connect = 10.36.3.144:4433 ============================= but I have got this error ======================================= file stunnel.conf line 5: Illegal SSL option 2005.03.31 13:26:48 LOG3[3396:3716]: Server is down ======================================= After I have changed the stunnel.conf in this way: stunnel.conf ============================== client = yes debug=7 ciphers = RC4-MD5 [telnet] accept = 23 connect = 10.36.3.144:4433 ============================== The problem I had is now solved. But my question is: how can I know more about this protocol incompatibility? Is there an accurate documentation about that and also about stunnel configuration? Sorry but sometimes it's difficult for me to find (in the FAQ or other sessions) the informations that I need. Thanks&Regards Maddalena

The IDEA algorithm is patented, but I don't think Mike included that in his builds. You can configure Stunnel to only use specific ciphers, in which case you wouldn't be using it regardless. Does that make it legal? Consult a lawyer. Software patents suck. I'd download the openssl.exe and the libs and run 'openssl.exe ciphers -v' and see exactly which ciphers it includes and avoid any from which your legal team suggess you run away. -- Brian Hatch If we aren't supposed Systems and to eat animals, why Security Engineer are they made of meat? http://www.ifokr.org/bri/ Every message PGP signed

Stunnel 4.09 released
by Michal Trojnara 26 Mar '05

26 Mar '05

New stunnel 4.09 can be found on my FTP site: ftp://stunnel.mirt.net/stunnel/ Here is the ChangeLog entry: * DLLs for OpenSSL 0.9.7f. * Bugfixes - Compilation problem with undeclarated socklen_t fixed. - TIMEOUTclose is not used when there is any data in the buffers. - Stunnel no longer relies on close_notify with SSL 2.0 connections, since SSL 2.0 protocol does not have any alerts defined. - Closing SSL socket when there is some data in SSL output buffer is detected and reported as an error. - Install/chmod race condition when installing default certificate fixed. - Stunnel no longer installs signal_handler on ignored signals. Best regards, Mike

So I am sending this message from another system running Win98 and stunnel-4.05, also using Netscape 4.6, which seems to work o.k. Please tell me how to get the right version number to work with stunnel-4.08, and WinXP. Additionally, it would be nice to know how to obtain the outputs suggested in the instructions for Stunnel-Users Mailing List.

Problems using STunnel with a non-default port - Please Help
by Chetan Rao 22 Mar '05

22 Mar '05

I have a personal webserver running on Win2K Pro SP4 that listens on port 17875. This server is accessible through my NAT and software firewall (ZoneAlarm Pro). I then installed STunnel with the following conf: [https] accept=4430 connect=17875 TIMEOUTclose=0 Now, when I access https://<server>:4430, I get a HTTP 400 (Bad Request) error message, with both Internet Explorer 6 and FireFox 1.01. However, if I change the accept port from 4430 to 443 (and make the appropriate changes on the NAT for port forwarding), and use https://<server>, it works. I don't want to use the standard port. What am I doing wrong? Here's the log that STunnel generated: 2005.03.16 08:33:26 LOG5[1044:288]: stunnel 4.08 on x86-pc-mingw32-gnu WIN32+IPv4 with OpenSSL 0.9.7e 25 Oct 2004 2005.03.16 08:33:26 LOG7[1044:1096]: RAND_status claims sufficient entropy for the PRNG 2005.03.16 08:33:26 LOG6[1044:1096]: PRNG seeded successfully 2005.03.16 08:33:26 LOG7[1044:1096]: Certificate: stunnel.pem 2005.03.16 08:33:26 LOG7[1044:1096]: Key file: stunnel.pem 2005.03.16 08:33:26 LOG5[1044:1096]: No limit detected for the number of clients 2005.03.16 08:33:26 LOG7[1044:1096]: FD 168 in non-blocking mode 2005.03.16 08:33:26 LOG7[1044:1096]: SO_REUSEADDR option set on accept socket 2005.03.16 08:33:26 LOG7[1044:1096]: https bound to 0.0.0.0:4430 2005.03.16 08:34:08 LOG7[1044:1096]: https accepted FD=180 from 192.168.0.2:4864 2005.03.16 08:34:08 LOG7[1044:1096]: FD 180 in non-blocking mode 2005.03.16 08:34:08 LOG7[1044:1096]: Creating a new thread 2005.03.16 08:34:08 LOG7[1044:1096]: New thread created 2005.03.16 08:34:08 LOG7[1044:896]: https started 2005.03.16 08:34:08 LOG5[1044:896]: https connected from 192.168.0.2:4864 2005.03.16 08:34:08 LOG7[1044:896]: SSL state (accept): before/accept initialization 2005.03.16 08:34:08 LOG7[1044:896]: SSL state (accept): SSLv3 read client hello A 2005.03.16 08:34:08 LOG7[1044:896]: SSL state (accept): SSLv3 write server hello A 2005.03.16 08:34:08 LOG7[1044:896]: SSL state (accept): SSLv3 write certificate A 2005.03.16 08:34:08 LOG7[1044:896]: SSL state (accept): SSLv3 write server done A 2005.03.16 08:34:08 LOG7[1044:896]: SSL state (accept): SSLv3 flush data 2005.03.16 08:34:08 LOG7[1044:896]: SSL state (accept): SSLv3 read client key exchange A 2005.03.16 08:34:08 LOG7[1044:896]: SSL state (accept): SSLv3 read finished A 2005.03.16 08:34:08 LOG7[1044:896]: SSL state (accept): SSLv3 write change cipher spec A 2005.03.16 08:34:08 LOG7[1044:896]: SSL state (accept): SSLv3 write finished A 2005.03.16 08:34:08 LOG7[1044:896]: SSL state (accept): SSLv3 flush data 2005.03.16 08:34:08 LOG7[1044:896]: 1 items in the session cache 2005.03.16 08:34:08 LOG7[1044:896]: 0 client connects (SSL_connect()) 2005.03.16 08:34:08 LOG7[1044:896]: 0 client connects that finished 2005.03.16 08:34:08 LOG7[1044:896]: 0 client renegotiatations requested 2005.03.16 08:34:08 LOG7[1044:896]: 1 server connects (SSL_accept()) 2005.03.16 08:34:08 LOG7[1044:896]: 1 server connects that finished 2005.03.16 08:34:08 LOG7[1044:896]: 0 server renegotiatiations requested 2005.03.16 08:34:08 LOG7[1044:896]: 0 session cache hits 2005.03.16 08:34:08 LOG7[1044:896]: 1 session cache misses 2005.03.16 08:34:08 LOG7[1044:896]: 0 session cache timeouts 2005.03.16 08:34:08 LOG6[1044:896]: SSL accepted: new session negotiated 2005.03.16 08:34:08 LOG6[1044:896]: Negotiated ciphers: RC4-MD5 SSLv3 Kx=RSA Au=RSA Enc=RC4(128) Mac=MD5 2005.03.16 08:34:08 LOG7[1044:896]: FD 200 in non-blocking mode 2005.03.16 08:34:08 LOG7[1044:896]: https connecting 127.0.0.1:17875 2005.03.16 08:34:08 LOG7[1044:896]: connect_wait: waiting 10 seconds 2005.03.16 08:34:08 LOG7[1044:896]: connect_wait: connected 2005.03.16 08:34:08 LOG7[1044:896]: Remote FD=200 initialized 2005.03.16 08:34:08 LOG7[1044:896]: Socket closed on read 2005.03.16 08:34:08 LOG7[1044:896]: SSL write shutdown 2005.03.16 08:34:08 LOG7[1044:896]: SSL alert (write): warning: close notify 2005.03.16 08:34:08 LOG7[1044:896]: SSL_shutdown retrying 2005.03.16 08:34:08 LOG7[1044:896]: s_poll_wait timeout waiting for SSL close_notify 2005.03.16 08:34:08 LOG5[1044:896]: Connection closed: 208 bytes sent to SSL, 389 bytes sent to socket 2005.03.16 08:34:08 LOG7[1044:896]: https finished (0 left) Any help much appreciated.

Hi all, I have a working setup of stunnel listening on port 443 and connect to the server on the same host on port 80. It is done via xinetd. Alltough everything is working just fine, clients on webbrowsers get the "you have choosen not to trust this CA" error when connecting to this server. In apache the certificate chain (bundle.ca) is used and clients connecting to the apache server wont get this error. Is there a way to make stunnel behave like apache, so the clients don't have to manually install the CA certificates? (the certificate is a vallid certificate obtained from globaslsign.be) i do have the CAfile in my options file, but this does not help. All help is greatly appreciated! Kind regards, @

Creating a man in middle attack for legit purposes.
by Todd Troutman 16 Mar '05

So I don't normally start off on a list by immediately asking a question but I've got a weird one here that's a critical thing tonight, plus, this might just be entertaining! Problem : MacOS Panther has horrible performance problems with large https web apps. So I setup Stunnel to take port 80 and run it through the web app on 443. Provides http from an https server. On a MacOS client machine I set /etc/hosts to say that system.netsuite.com, the web app, is 192.168.0.4, a handy FreeBSD 5.3 box running stunnel 4.05 It works. Sort of. Problems - the web app keeps rewriting the url from http to https, anytime I click on anything, hmmm.. so I can't make stunnel answer on 443 because then I'm back to square one. Also, I can't login, the web app is giving me a login page as http, but I get a session timeout,please login again, just repeats, unsure if something in the stunnel config should be done to fix that. Other than that, this is working. Config is currently this. client=yes accept=80 connect=system.netsuite.com:443 Anyway, so is this maybe one of the stranger uses of stunnel, possibly a wrong headed and broken way of using it, but oh well. There goes my plea for some ideas on this one, Thanks, Todd

Radius over Stunnel??
by Frazer, Andrew non Unisys 08 Mar '05

08 Mar '05

Hello all.. I would like to pass radius over stunnel, but I'm not sure if this will work... I have a lot of 'client's that are using RADIUS for authentication, but i want to pass the data over the internet, and radius is relatively insecure. My client machines also run a web server, which stunnel sits in front of, to provide ssl encrypted web services. My radius servers can easily run stunnel, without any issue. Could someone suggest a configuration for this??

syslog question
by Brian T 04 Mar '05

04 Mar '05

If debug=4 ( or not 0 ) and output= is commented in an stunnel config, it looks like in server mode, messages goto syslog. But in client mode, nothing goes to syslog. Is this the way it's supposed to be? -Brian

Re: [stunnel-users] long delay to close the ssl session ?
by ikeda＠areabe 04 Mar '05

04 Mar '05

If TIMEOUTclose value is positive, stunnel does not transmit TCP FIN, even though application sends TCP FIN, until timeout time expires I don't know why stunnel designer chose it, maybe because of the performance, or some others. Some of the browsers do not start to display the page until receiving the entire packet. And one of the trigger for the browser to detect to receive the whole is TCP FIN. From that things, such kind of the problem of yours occurs. regards taka On Fri, 4 Mar 2005 10:39:47 -0800 (PST), gary ng <garyng2000(a)yahoo.com> wrote: > Thanks, that did the trick.

long delay to close the ssl session ?
by gary ng 04 Mar '05

04 Mar '05

Hi, I am using stunnel to wrap SSL around SWAT. Everything works fine except that it takes a very long delay for the browser to see that the page has already been transmitted completely(in other words, the other end has closed). I observed this behaviour with both 3.x and 4.x stunnel. Looking through the log, I see that it takes exactly one minute from the start of the session till the session is closed, seems to be some parameter within stunnel to hold the session. I tried both inetd as well as stand alone stunnel mode and both behave the same as well. Is this an issue with SWAT or stunnel ? If I just use plain SWAT through inetd, I don't see this behaviour. thanks for any help in advance. gary __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

Naive question: will stunnel connect dynamically?
by Duncan Murdoch 02 Mar '05

02 Mar '05

I currently use openssh to open a tunnel between my laptop and my POP3 server, but the tunnel keeps locking up. (I think it's a server problem, or an intermittent line problem, because it happens with both openssh and Putty.) What I'd like is a program that would open the tunnel only as needed, so I can get the mail, and let the tunnel close. Can stunnel do this? More generally, is there a quick summary somewhere on the relative benefits of stunnel's use of SSL versus an SSH approach? Duncan Murdoch

Windows XP Pro as a client of Remote Dekstop via stunnel
by Jacek Baszkiewicz 02 Mar '05

02 Mar '05

Hi! I'm currently working (without success) on such problem: I have to connect via Stunnel to Windows Server Remote Desktop from workstation with Windows XP Proffesional. When I refer to the local port handled by stunnel, Windows doesn't let me go go further, because it thinks that I'm trying to use local Remote Dekstop and prints: "You are already connected to this machine" (there can be only one connection through RD) . Is there any workaround for this problem, namely, to use secure connection via Stunnel to Remote Dekstop on XP Pro client? This is my config: client=yes cert = stunnel.pem [ts] accept=localhost:3389 connect=remote_ip:443

stunnel woes under HPUX 10.20
by foner-stunnel＠media.mit.edu 28 Feb '05

28 Feb '05

[Please keep me CC'ed on replies! I'm not on any stunnel lists.] Stunnel 4.07 and 4.08 don't build under HPUX 10.20. 4.06 appears to build, but doesn't appear to work---with a config file like this, running on the local host: pid = /usr/local/var/stunnel/stunnel.pid client = yes foreground = yes # debug = debug [pop3s] accept = 110 connect = our-pop-host:995 ...and an attempt like this, using (for instance) Emacs 21.4a's movemail: movemail po:foner:localhost NEWMAIL [the-password] ...I get an infinite hang. Enabling debugging causes stunnel to spit out an infinite stream of a single line at maximum rate, and seems unaffected by whether I'm trying to connect to it or not: # stunnel test-stunnel.conf 1900.01.00 00:00:00 LOG5[9738:0]: stunnel 4.06 on hppa1.1-hp-hpux10.20 FORK+POLL with OpenSSL 0.9.7e 25 Oct 2004 1900.01.00 00:00:00 LOG7[9738:0]: Snagged 64 random bytes from /users/foner/.rnd 1900.01.00 00:00:00 LOG7[9738:0]: Wrote 1024 new random bytes to /users/foner/.rnd 1900.01.00 00:00:00 LOG7[9738:0]: RAND_status claims sufficient entropy for the PRNG 1900.01.00 00:00:00 LOG6[9738:0]: PRNG seeded successfully 1900.01.00 00:00:00 LOG6[9738:0]: file ulimit = 60 (can be changed with 'ulimit -n') 1900.01.00 00:00:00 LOG6[9738:0]: poll() used - no FD_SETSIZE limit for file descriptors 1900.01.00 00:00:00 LOG5[9738:0]: 27 clients allowed 1900.01.00 00:00:00 LOG7[9738:0]: FD 3 in non-blocking mode 1900.01.00 00:00:00 LOG7[9738:0]: FD 4 in non-blocking mode 1900.01.00 00:00:00 LOG7[9738:0]: FD 5 in non-blocking mode 1900.01.00 00:00:00 LOG7[9738:0]: SO_REUSEADDR option set on accept socket 1900.01.00 00:00:00 LOG7[9738:0]: pop3s bound to 0.0.0.0:110 1900.01.00 00:00:00 LOG7[9738:0]: Created pid file /usr/local/var/stunnel/stunnel.pid 1900.01.00 00:00:00 LOG6[9738:0]: daemon_loop: s_poll_wait: Invalid argument (22) 1900.01.00 00:00:00 LOG6[9738:0]: daemon_loop: s_poll_wait: Invalid argument (22) 1900.01.00 00:00:00 LOG6[9738:0]: daemon_loop: s_poll_wait: Invalid argument (22) 1900.01.00 00:00:00 LOG6[9738:0]: daemon_loop: s_poll_wait: Invalid argument (22) [ . . . and forever more . . . ] I can't imagine that this is supposed to be how debug works, since it's totally useless for debugging if it spits out the same line as fast as it can. I'm running the stunnel as root, and netstat seems to show that it's bound to port 110, but doesn't seem to indicate any outbound connection from stunnel to our pop host after I invoke movemail. I have no idea if versions before 4.06 work; I haven't tried. Sure, this is an old OS, but zillions of other things, including the entire GNU toolchain, seem to work on it, so stunnel should, too. Builds for all three versions I've tried may be found in at the following URLs. Note that 4.07 and 4.08 fail on different files, but in essentially the same way. http://foner.www.media.mit.edu/people/foner/Sys/stunnel-4.06.build http://foner.www.media.mit.edu/people/foner/Sys/stunnel-4.07.build http://foner.www.media.mit.edu/people/foner/Sys/stunnel-4.08.build I've done some websearching, and I've searched the stunnel archives at mirt.net, but haven't found anything relevant. Any clues? Thanks...

stunnel logging problem
by Brian T 28 Feb '05

28 Feb '05

Hi, I work for a company which has a custom embedded Linux platform, and have been working with stunnel for some time but have never seen this problem. I have seen it with stunnel 4.04 and 4.07, which is compiled on a Redhat 7.2ish platform, but newer SSL libraries. (below my sig is the stunnel info). Basically I use a config file, but when debug= and output= is commented out, stunnel seems to cause a problem which resets the embedded unit. If I uncomment them both and use output=/var/log/stunnel.log ( or /dev/null ) everything works fine. Not sure where to look for the problem that is causing this since I can't even get a core dump. I looged in s_log() but nothing stuck out as being wrong.

openssl - generating stunnel.pem - stunnel.cnf
by k-i-r＠web.de 24 Feb '05

24 Feb '05

Using Stunnel under Windows I want to create a certificate (stunnel.pem) with Openssl. According to FAQ the syntax for creating a certificate with Openssl is openssl req -new -x509 -days 365 -nodes -config stunnel.cnf -out stunnel.pem -keyout stunnel.pem I use openssl for windows (as part of apache-windows-http-server) . Where do I get the file stunnel.cnf ? Or is this file not necessary for creating a certificate ? Thanks for help, k.

Stunnel and configuration
by Bohdan Linda 22 Feb '05

22 Feb '05

Hi all, I have configured stunnel to do the client authetication, but I have some question. I have used following config: cert = /etc/certificates/server.pem - file with signed server cert and key (passwordless) chroot = /var/run/stunnel/ CAfile = /etc/certificates/certs -file where first item is my CA certificate followed by list of all client certificates sgined by my CA. setuid = nobody setgid = nogroup pid = /stunnel.pid verify = 3 This setup is working, but this seems to me very "unlogical". If I create for me "more logic" setup: cert = /etc/certificates/server.pem chroot = /var/run/stunnel/ CAfile = /etc/certificates/CA/cacert.pem - only certificate of my CA CRLfile = /etc/certificates/crls - only certificates signed by my CA I get the following error: 2005.02.22 15:15:10 LOG5[22418:81926]: VERIFY OK: depth=1, /C= ..... 2005.02.22 15:15:10 LOG4[22418:81926]: VERIFY ERROR ONLY MY: no cert for /C= The question is ... why? Why CAfile has to contain all client certificates, when clients certs are not CA? Why I cannot have separate file for CA and separate file for certificates that I want accept? If I do the similar setup in mod_ssl, the configuration works as expected. Anyway, I'am newbie to deploy stunnel, thus I would like to ask you for giving me you opinion of this configuration, caveats and possible enhancements. Thanks for any comments, Bohdan Linda

multiple stunnel client
by Manila, Dinesh - Contractor 15 Feb '05

15 Feb '05

Hi, I am working in a project, whereas the EMS application need to be secured while communicating with NE. To make it secure, we have decided to go with stunnel and openSSL. I have following questions while using stunnel in my application: 1. I read that stunnel limits the number of clients to be connected to 125. Can I increase this number. If so, by increasing this number, what is the implication in performance of stuunel. 2. Since my EMS is capable of managing more than 1000 NEs, I would want to have multiple stunnel client running on the same workstation. Is this possible to have multiple stuunel process running on the same server. if so, how should my stunnle.conf file look like. I appreciate greatly, If I could get the answers for the above queries. Thanks and Regards, Dinesh Wipro Technologies. Bangalore.

Multiple listeners with just one instance of Stunnel?
by Michael Zarlenga 15 Feb '05

15 Feb '05

It doesn't seem possible to start 1 instance of Stunnel for multiple accept ports. Judging by the format of the Stunnel configuration file, it seems that I need to 1 instance of Stunnel for each port that accepts connections from the outside world. Is this true?

using no certificate
by Zohar 14 Feb '05

14 Feb '05

Hi, I'm very new to all this issue of SSL, so I apologize if this question sounds stupid. I currently have a server that listens to connections on a TCP port. Clients that connect to it may do so using SSL v3 (mobile clients, which use their own SSL packages, so I have very little control over it). I want to add stunnel to my server's setting, to enable SSL communication. I have no need for the client to authenticate the server, I am only interested in the data being encrypted. I tried setting this up, but the client complains that my server certificate cannot be authenticated (I produced it using http://www.stunnel.org/pem/). Any pointers on how to set such a thing up (even for the time being, while I develop), without having to pay lots of money to a CA ?

Multiple Instances of stunnel
by dps_maillists＠mac.com 11 Feb '05

11 Feb '05

Hi everyone; Is it possible to run multiple instances of stunnel (v 4.07) in client mode on a single machine? We sould like to use stunnel to secure connections from a small number of client applications (1 to 10) connecting to a larger number of server applications (200 per client app). Ideally, we would like to use one instance of stunnel per client. Many thanks in advance. Doug

concurrency request
by kevin 01 Feb '05

01 Feb '05

hi, I've recently set up stunnel for SSL connect. When I test its performance with siege with 700 concurrency request, I got this log: "Error: socket: connection timed out.: Operation now in progress" So, may I ask what is the upper limit of concurrency in stunnel, if the performance of the machine is good enough. and how can I increase the concurrency upper limit. thanks

Q: rereading configuration file?
by Heiko Nardmann 01 Feb '05

01 Feb '05

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi! Does stunnel offer a way to signal a need for rereading the configuration file, i.e. some kind of SIGHUP ? I would like to add services while running stunnel without stopping the program ... it should compare currently available services with the new list of services, stop the ones not available any more and start those which are new in the new/changed configuration ... - -- Heiko Nardmann (Dipl.-Ing.

Q: need of restart after CRL/CA directory contents change?
by Heiko Nardmann 31 Jan '05

31 Jan '05

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi! Since I want to write CRL files from all relevant CAs based on a regular (daily) basis I wonder whether it is necessary to restart stunnel if the contents of the CRL or CA directory changes. The regular part is going to be handled by a cronjob which does an LDAP search which results in the CA certificate and crl files. How does stunnel work in this situation? Do I need a restart after a cron run or not? Thanks in advance! - -- Heiko Nardmann (Dipl.-Ing.

Hi, I've initiated 11 stunnel processes in the same server. Each of the stunnel process has its own client certificate to communicate to application server. However after sometime of execution, the stunnel processes are crached (dying off) one by one. below is the last portion of my log (with debug level 7). I don't see any critical error in the log. Would appreciate if someone could highlight to me what cause the problem or anyone has similar experience. 2005.01.25 16:02:41 LOG7[2244:1424]: 0 server connects that finished 2005.01.25 16:02:41

Profiling STunnel
by Mark Swann 26 Jan '05

All, I need to do some performance profiling on STunnel. I assume gcov and gprof are the correct tools for this. Does anyone have any experience profiling STunnel? Any advice on how to do it properly would be appreciated. Thanks Mark Swann

Cannot find License.CM file
by Ranjit Mallick 26 Jan '05

26 Jan '05

Hi , I am new to stunnel , one of the previous develoeper has developed a application using Stunnel, essentially this app will work as a proxy to outside world and tunnel back to the remote server. On the server side the Stunnel has License.cm file and when ever I bring stunnel in CMD mode, it shows a message cannot find the License.cm file(even though it is there), Obviously the License file has expired or corrupted. How do I tell this tunnel.exe not to look for that file or how can I generate a license file(.cm)? Pls note that the tunnel has all the required files in it's directory tunnel.pem,tunnel.conf,ssleay32.dll,libeay32.dll,ssleay32.exp), pls help this is a show stopper and is effecting the client.Any leads or direction will be much appreciated. Thank you Ranjit __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

win32 stunnel - quiet service install
by joe smith 22 Jan '05

22 Jan '05

I would like to request the following feature be included in subsequent releases of stunnel. Cheers, Jeff Greetings, It would be great if while installing as a service on win32, there was an option to install quietly - i.e. only pop up a dialog box to the user if there's a problem. Any chance of somebody nice compiling me a binary that does this? :) M. -- Michael Brown {0x527670C0} | `One of the main causes of the fall of Systems Administrator | the Roman Empire was that, lacking zero, +1 519 888 7111 x2339 | they had no way to indicate successful michaelb at opentext.com | termination of their C programs.' - Firth --------------------------------- Do you Yahoo!?

stunnel and verify
by Brian Hirt 21 Jan '05

21 Jan '05

Hi, I've recently set up stunnel for a remote vnc connection, and it's working great. However, I would like to restrict access based on cert (only allow access a single public key), because nobody else should be accessing it besides my one machine. It seems what i want is to set verify = 3, but I'm using self-signed certs on my client, so verify = 3 fails. Is there some way to verify the client public key without doing the self signed test too? I'm sorry if this is a faq -- i searched the lists and read the faq and couldn't find anything. Thanks! (I'm running stunnel 4.04 on fedora1, and stunnel 4.04 on mac 10.3.7, installed via fink) my stunnel.conf is pretty simple. client conf is (sans connection info) client = yes cert = /sw/etc/stunnel/stunnel.pem chroot = /var/run/stunnel/ pid = /stunnel.pid setuid = stunnel setgid = stunnel server conf is: client = no cert = /etc/stunnel/stunnel.pem CApath = /etc/stunnel/clientdb chroot = /var/run/stunnel/ verify=3 pid = /stunnel.pid setuid = stunnel setgid = stunnel -------------------------------------------- MobyGames http://www.mobygames.com The world's largest and most comprehensive gaming database project

As it is already present in the services list, this has to fail. You can easily start and stop stunnel using the net command from a command line window: net start stunnel to start stunnel, or: net stop stunnel to shut it down again. You could make up a batch file to launch stunnel automatically for the time agent is running: --file runagent.cmd begin-- @echo off net stunnel start C:\Program Files\Agent!\Agent32.exe net stunnel stop --file runagent.cmd end-- Just edit the path for agent32.exe to match the path where you have Forté Agent installed, and you're done. P.S. I know net stunnel start can complain about that the service is already running, but that's just cosmetical and I was too lazy to implement logic to check if the service is already running ;) Best regards, Andre

Activating Stunnel After Exiting (Newbie)
by mhrtmhd94＠att.net 20 Jan '05

20 Jan '05

Hi. I just installed Stunnel, in order to be able to continue Agent as my mews reader. This works well. Based on the cautions on the website, I have decided to keep Stunnel active only when I am using Agent. Stunnel opens when I boot Windows - (XP Home Edition with Service Pack 2.) After close Agent, I right-click the Stunnel icon on the task bar and choose Exit. If I try to activate Stunnel later, by double-clicking its desktop icon, I am presented with an error window headed "stunnel 4.07 on Win32" with the following message: "Failed to create a new service". Looking at Properties on the desktop, I see that the Target is "C:\stunnel\stunnel-4.07.exe -install". This looks wrong, as it appears to be the option for initial installation of the program. I assume I need to change this, or discover another method of re-opening stunnel. As it stands now, I have to reboot to accomplish this. Any assistance will be appreciated. Thanks.

stunnel dropping connection with media wiki
by christopher＠baus.net 12 Jan '05

12 Jan '05

Hi all, I've been using stunnel with SMTP, IMAP, and HTTP with out a problem. Yesterday I installed media wiki on Fedora Core 2 w/ Apache. It works fine if I access it directly, but if I access the site via stunnel, the proxy drops connection. I was wondering if anybody else has seen this type of problem. I am tempted to dig into it, but I am honestly short on time right now. I think it might have something to do with the redirects that Media wiki uses, but that's just a wild guess.

Stunnel and DistCache Patch

we have a RedHat 7.2 system and we are trying to apply the distcache_geoff.patch to enable distcache 1.4.5 with stunnel-4.04. We have run into a snag after the configure script is run and we attempt the "make", it complains that configure.in is missing.

Newbie trying to connect over a Microsoft Proxy
by Michael Blake 05 Jan '05

05 Jan '05

Hi All I'm a relative newbie to Stunnel, and am trying to set up a tunnel so I can Remote Desktop from work to my PC/server at home. I'm using versions 4.05 & 4.06 of the Windows binaries. A Microsoft Proxy Server v2.0 is used at work, and it proxies HTTP, Secure (is that SSL/port 443??), FTP and Gopher over port 800. I'm not sure if it proxies Socks, as there's no entry for it in Internet Explorer. I've tested the configuration and it works on my LAN, and it works from home when I enter my domain home (so my firewall is set up correctly). My config is as follows: #Client CAfile = stunnel.pem cert = stunnel.pem client = yes verify = 3 [rdp-80] accept = localhost:3390 connect = xxx.xxx.xxx.xxx:80 #Server CAfile = stunnel.pem cert = stunnel.pem client = yes verify = 3 [rdp-80] accept = 192.168.10.221:80 connect = 127.0.0.1:3389 Is there something I need to do to traverse this proxy?

Port forwarding based on application type
by Konda Ankireddyapalli 03 Jan '05

03 Jan '05

Hello all, Can stunnel forward the traffic to different ports based on an application type as opposed to by port? If yes, how can it be configured? My need is that on the client side we have many applications that share a single outgoing port. On the server side I want to demultiplex the stunnel traffic coming in on a single port to multiple applications after decryption. Thanks in advance, Konda

A couple of patches against 4.06
by Peter Pentchev 31 Dec '04

31 Dec '04

Hi, First of all, thanks for writing and maintaining this great piece of software :) When I ported 4.06 to FreeBSD on Monday, there were three changes that needed to be made. One is the passing of -1, not -1000, to poll(2), which has already been discussed on this list (and which, by the way, is mandated by POSIX and the Single Unix Specification, as you can see at http://www.opengroup.org/onlinepubs/007908799/xsh/poll.html ) The other two can be seen in the patch below. The first one is related to the fact that EAI_NODATA is not present on all systems - it was actually obsoleted by the KAME implementation of IPv6 about an year ago. On some systems it is defined and has its own value - then stunnel builds just fine. On other systems it is not defined at all, while on yet other systems it is aliased to EAI_NONAME, so 'case EAI_NONAME' and 'case EAI_NODATA' would produce an error message from the compiler. Thus, the #ifdef and #if in the first chunk of the patch. This could not be done portably with a single statement, something like '#if defined(EAI_NODATA) && EAI_NODATA != EAI_NONAME', since there are some compilers that would barf on the second part if EAI_NODATA was not actually defined. The second chunk of the patch fixes getnameinfo() error reporting - just like with getaddrinfo(), getnameinfo() errors should be displayed using s_gai_strerror() instead of sockerror(). Keep up the good work!

using stunnel for smb networking
by David Bear 28 Dec '04

28 Dec '04

out of curiousity, has anyone been able to use stunnel as a cheap vpn for smb/cifs windows networks? We have a stupid firewall policy that blocks ALL port 139 traffic. Yes, thats good most of the time since microsoft rpc's are notoriously insecure. It does cause a problem when we have other units at other universities with different firewall policies however, so I was hoping to go around the different bureacracies and tunnel it myself. just curious. -- David Bear phone: 480-965-8257 fax: 480-965-9189 College of Public Programs/ASU Wilson Hall 232 Tempe, AZ 85287-0803 "Beware the IP portfolio, everyone will be suspect of trespassing"

stunnel 4.06 problems with service on XP
by Mat Leinmueller 28 Dec '04

28 Dec '04

Hi, I tried to upgrade an existing 4.04 stunnel service to 4.06 (uninstalled service, reinstalled with new version). The service gets registered correctly, when I try to start it, however, it seems not to find the stunnel.conf file. After downgrading to 4.04 everything works again. Any suggestions? Mat

Error when executing stunnel 4.06 Windows binaries as service
by Liron Newman 28 Dec '04

28 Dec '04

Hello, I'm trying to run the offical stunnel 4.06 Win32 binaries from stunnel.org as a service, but I get the following error: "The procedure entry point freeaddrinfo could not be located in the dynamic link library WS2_32.DLL" I looked it up a bit and it seems to have something to do with IPv6, but I don't use it.. stunnel 4.05 works fine as a service, and worked without a problem for months now. I'm using Win2k SP4 fully patched. Help? :)

Stunnel 4.06 released
by Michal Trojnara 25 Dec '04

25 Dec '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Here is the ChangeLog entry: Version 4.06, 2004.12.26, urgency: LOW: * New feature sponsored by SURFnet http://www.surfnet.nl/ - IPv6 support (to be enabled with ./configure --enable-ipv6). * New features - poll() support - no more FD_SETSIZE limit! - Multiple connect=host:port options are allowed in a single service section. Remote hosts are connected using round-robin algorithm. This feature is not compatible with delayed resolver. - New 'compression' option to enable compression. To use zlib algorithm you have to enable it when building OpenSSL library. - New 'engine' option to select a hardware engine. - New 'TIMEOUTconnect' option with 10 seconds default added. - stunnel3 perl script to emulate version 3.x command line options. - French manual updated by Bernard Choppy <choppy AT free POINT fr>. - A watchdog to detect transfer() infinite loops added. - Configuration file comment character changed from '#' to ';'. '#' will still be recognized to keep compatibility. - MT-safe getaddrinfo() and getnameinfo() are used where available to get better performance on resolver calls. - Automake upgraded from 1.4-p4 to 1.7.9. * Bugfixes - log() changed to s_log() to avoid conflicts on some systems. - Common CRIT_INET critical section introduced instead of separate CRIT_NTOA and CRIT_RESOLVER to avoid potential problems with libwrap (TCP Wrappers) library. - CreateThread() finally replaced with _beginthread() on Win32. - make install creates $(localstatedir)/stunnel. $(localstatedir)/stunnel/dev/zero is also created on Solaris. - Race condition with client session cache fixed. - Other minor bugfixes. * Release notes - Win32 port requires Winsock2 to work. Some Win95 systems may need a free update from Microsoft. http://www.microsoft.com/windows95/downloads/ - Default is *not* to use IPv6 '::' for accept and '::1' for connect. For example to accept pop3s on IPv6 you could use: 'accept = :::995'. I hope the new syntax is clear enough.

Fwd: [stunnel-users] stunnel 'options' section of config file
by Justin Miller 21 Dec '04

21 Dec '04

I understand the security concerns... I was just trying different protocols because I was receiving weird error messages with some https proxies (using the mathias wald patch) about wrong version numbers, etc. Googling it seemed to indicate that enabling/disabling ssl2/ssl3/tls1 could do the trick. However, I can't even get 'openssl s_client...' to yield a successful connection with some of these proxies. Can stunnel handle incoming http or socks proxy requests/connections? If not, will you ever support that? For instance I want stunnel listening on a local port 8080 and connect to a remote https proxy, and I set the HTTP proxy server in gaim to localhost:8080. -Justin On Tue, 21 Dec 2004 15:20:19 +0100, Michal Trojnara <Michal.Trojnara(a)mobi-com.net> wrote: > Justin Miller wrote: > > So all looks well ang good...

stunnel 'options' section of config file
by Justin Miller 21 Dec '04

21 Dec '04

Is it just me, or does stunnel not seem to obey the ssl 'options' setting in the config file? I have the lines: options = TLS_ROLLBACK_BUG options = NO_TLSv1 options = NO_SSLv3 And when I start stunnel, the output is: 2004.12.20 07:47:46 LOG7[9981:1024]: Configuration SSL options: 0x06800000 2004.12.20 07:47:46 LOG7[9981:1024]: SSL options set: 0x06800000 So all looks well ang good... But then when it sends the client hello message, one would expect an ssl2 message, but we get the following output: 2004.12.20 07:47:51 LOG7[9984:1026]: SSL state (connect): SSLv3 write client hello A 2004.12.20 07:47:51 LOG7[9984:1026]: waitforsocket: FD=10, DIR=read 2004.12.20 07:47:51 LOG7[9984:1026]: waitforsocket: ok 2004.12.20 07:47:51 LOG7[9984:1026]: SSL alert (write): fatal: handshake failure 2004.12.20 07:47:51 LOG3[9984:1026]: SSL_connect: 1408F10B: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number That first line seems to indicate that it's still sending a v3 message. Is this actually what's happening?
