stunnel 4.14 errors and dropped connection
by stunnelusers＠tinfoil.cotse.net 21 Jan '06

21 Jan '06

Hello, If I leave my computer downloading via stunnel and come back to it later, I find the download has stopped halfway and in the stunnel log it says: SSL_read: Connection reset by peer (WSAECONNRESET) (10054) and then a number of lines like: Error resolving 'xxx.xxx.xxx': Neither nodename nor servname known (EAI_NONAME) where xxx.xxx.xxx is the url I was downloading from. I am using stunnel 4.14 on win xp. If I try to load a web page like google I get told it cannot be found. I have to switch off the router and switch it back on. When Windows finds the "new" connection it resets itself and everything works perfectly again, for a while, and then it happens all over again. This did not happen before I upgraded to 4.14. What is happening? Why is it happening? How do i stop it? Thanks.

RE: [stunnel-users] exclusively TLS
by Moehrke, John (GE Healthcare) 20 Jan '06

20 Jan '06

It is not the list of ciphers that I want to choose from. We are indeed using a select set of ciphers and that seems to be working fine. My problem is that when stunnel connects to the server it is trying sslv3, and this causes an error as the server is only supporting TLS. I could easily be wrong...

exclusively TLS
by Moehrke, John (GE Healthcare) 20 Jan '06

I need to talk to a server that is requiring pure TLS. It seems that STUNNEL always starts with SSL. How do I get STUNNEL to start the client side conversation with TLS?

Stunnel in a three tier setup
by Louis Young 19 Jan '06

19 Jan '06

Hi Guys I would like to set up stunnel in a three tier environment, i.e. instead of just having a client and a server, I have a client, midware and server. I tried doing this: On the client: [VNC on TestMachine] accept = 9000 connect = 192.168.100.12:9000 192.168.100.12 is the "mid-ware" machine: On this "mid-ware" machine: [VNC on TestMachine] accept = 9000 connect = 192.168.100.16:9000 192.168.100.16 is the destination: Then on the destination: [VNC] accept = 9000 connect = 192.168.100.16:5900 The only machine with client=yes is the client and they all use the same key. If I change the settings on the client to point directly to the destination (i.e. using only two machines), it works, but with three machines there seems to be a problem Any ideas?

verify server certification is missing
by Olivier twist 17 Jan '06

17 Jan '06

I think a functionnality is missing in stunnel. I compare the behaviour of stunnel and apache mod-ssl. If you have a certificate signed by third party, apache checks the root certificate like stunnel do this with -v 1 option but apache don't ask for a client certificate, stunnel do this :-( I think that stunnel should control server certificate chain defined in CA file even if option -v 1 is not set !!! Could you give your opinion? If I use stunnel and not apache it's because I have some protocols to handle with ssl and stunnel is a very easy to use solution. Thanks Oliver

Delay option
by Stefaan Van Dooren 16 Jan '06

16 Jan '06

Hi, I'm setting up stunnel and I'm facing a problem with dynamic IP-adresses. Searching google and the man pages I tought that the "delay = yes" option would solve my problem, but it doesn't seems to. If I had "delay = yes" to my config file, none of my services seems to work anymore. If I remove it, everything is working fine, until the the remote-IP changes, and I have to restart stunnel. What am I doing wrong ? Or isn't this the right option for this job ?

Some newbie question for stunnel
by Thomas Stein 13 Jan '06

13 Jan '06

Hello, After reading some doc pages about stunnel I have still some questions: 1.) I read that the client part of a pop3 connection (e.g. for GoogleMail) is like stunnel -c -d pop3 -r bar:pop3s However I did not found any explations of the flags -d, -d and -r When I type stunnel -help none of these flags are explained. 2.) Can I replace pop3 and pop3s in the command above by real port numbers? 3.) Is stunnel compatible with SSH servers ? In other words: can stunnel on the local machine communicate with a SSH server on the remote computer and vice versa? 4.) Is there a timeout function? Read: When I start stunnel I would like to exit the service after lets say 5 minutes automatically. Is there such a feature/option? 5.) Has someone experiences with googlemail pop3 retrieval of emails? Is the following stunnel command recommendable for googlemail.com? stunnel -c -d pop3 -r pop.googlemail.com:pop3 Thank you in advance for the answer Thomas -- ___________________________________________________ Play 100s of games for FREE! http://games.mail.com/

Sniffing the network --how to disable SSL?
by david-e.hansen＠ubs.com 12 Jan '06

12 Jan '06

Hi, I know this sort of defeats the whole purpose of stunnel, but I have an LDAP server which listens for non-SSL on one port, and SSL on another. We decided to use stunnel and the SSL port on our LDAP server for security purposes. However, now we need to see the communication between clients and the LDAP server, in order to debug a production problem. Sniffing won't be terribly useful unless we can turn off the SSL encryption of the communication. I can't just re-point the application to the non-SSL port because this is stored in a central database and would affect everyone (it's a 3rd pty app), so I just want to change the stunnel.conf file on my PC so that it does port-forwarding but no encryption. Is this possible to do? Regards, David E.

Connection reset by peer on same local network?
by Gabe Martin-Dempesy 03 Jan '06

03 Jan '06

I'm attempting to setup an encrypted rsync to pull backups off of a file server onto a safe backup machine. To do this I'm using a combination of stunnel and rsyncd (It needs to pull root-owned files, so -e ssh wouldn't work unless I want to have a backup script remotely logging in as root!!) For now the machines are both on the same local network, 10.10.10.0/24, but I'm have weird problems with stunnel getting a 'connection reset by peer' after a couple minutes of the rsync, halting the transfer prematurely. Here's what I see in the logs: Client: Dec 29 10:19:21 backup stunnel[2568]: 8001 connected from 127.0.0.1:39215 Dec 29 10:21:09 backup stunnel[2568]: SSL_write: Connection reset by peer (104) Dec 29 10:21:09 backup stunnel[2568]: Connection reset: 192532 bytes sent to SSL, 5920666 bytes sent to socket Server: Dec 29 10:20:00 proto stunnel[30434]: 973 connected from 10.10.10.20:54054 Dec 29 10:20:00 proto rsyncd[1776]: rsync on xserve from localhost (127.0.0.1) Dec 29 10:21:49 proto stunnel[30434]: SSL socket closed with 16384 byte(s) in buffer Dec 29 10:21:49 proto stunnel[30434]: Connection reset: 5953434 bytes sent to SSL, 98416 bytes sent to socket Dec 29 16:21:49 proto rsyncd[1776]: rsync: writefd_unbuffered failed to write 4096 bytes: phase "unknown": Connection reset by peer Dec 29 16:21:49 proto rsyncd[1776]: rsync error: error in rsync protocol data stream (code 12) at io.c(666) Note that the client gets the 'connection reset by peer' a good 40 seconds before the server notices the disconnect. Here are the associated stunnel.conf's, which are pretty basic Client: cert = /etc/stunnel/backup.crt key = /etc/stunnel/backup.key setuid = stunnel setgid = stunnel pid = /var/run/stunnel/stunnel.pid socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 client = yes [8001] accept = 8001 connect = 10.10.10.15:973 Server: cert = /etc/stunnel/proto.crt key = /etc/stunnel/proto.key setuid = stunnel setgid = stunnel pid = /var/run/stunnel/stunnel.pid socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 [973] accept = 973 connect = 127.0.0.1:rsync Both are using: stunnel 4.09 on i686-pc-linux-gnu PTHREAD+POLL+IPv6+LIBWRAP with OpenSSL 0.9.7e 25 Oct 2004 Global options cert = /etc/stunnel/stunnel.pem ciphers = ALL:!ADH:+RC4:@STRENGTH debug = 5 key = /etc/stunnel/stunnel.pem pid = /var/lib/run/stunnel.pid RNDbytes = 64 RNDfile = /dev/urandom RNDoverwrite = yes session = 300 seconds verify = none Service-level options TIMEOUTbusy = 300 seconds TIMEOUTclose = 60 seconds TIMEOUTconnect = 10 seconds TIMEOUTidle = 43200 seconds Both of these machines are Gentoo 2005.1, updated to current, using the hardened 2.6 profile. Neither of them use non-standard make flags. Does anyone have some insight? There shouldn't be any "peer" (besides themselves) in the way between these two boxes to disconnect them.

RE: [stunnel-users] Connection reset by peer on same local networ k?
by Jeremy Simons 03 Jan '06

03 Jan '06

The problem is not with stunnel, but with rsyncd. I assume you are running rsyncd on the source machine in conjunction with the /etc/rsyncd.conf file. The cool thing about running rsyncd through stunnel is the rsync client appears to the rsyncd as a local machine (obviously) so permissions are a problem. The best way I could recommend since you need to access root owned files would be to setup your rsyncd entry something like: ## Example of full access to /home directory [home] uid = root gid = root path = /home comment = home directory. hosts allow = 127.0.0.1 read only = no ignore nonreadable = no refuse options = checksum dont compress = * If you notice the "hosts allow" directive only allows access from localhost(127.0.0.1). The problem is *anyone* can connect to your stunnel server unless you require security I would recommend using your firewall to allow access to your stunnel instance and also to use non-standard ports (I.E. 50000-50010). Using a firewall in lieu of authentication is obviously NOT secure or even recommended for a production environment but is simply added security that certainly doesn't hurt. The workaround would be to secure stunnel and leave rsyncd wide-open to localhost. As for the "connection reset" errors I was getting the same thing until I upgraded to the latest version of stunnel. I read a post on stunnel.mirt.net about it. Are you sure you're using the latest version of stunnel?

I'm attempting to setup an encrypted rsync to pull backups off of a file server onto a safe backup machine. To do this I'm using a combination of stunnel and rsyncd (It needs to pull root-owned files, so -e ssh wouldn't work unless I want to have a backup script remotely logging in as root!!) For now the machines are both on the same local network, 10.10.10.0/24, but I'm have weird problems with stunnel getting a 'connection reset by peer' after a couple minutes of the rsync, halting the transfer prematurely. Here's what I see in the logs: Client: Dec 29 10:19:21 backup stunnel[2568]: 8001 connected from 127.0.0.1:39215 Dec 29 10:21:09 backup stunnel[2568]: SSL_write: Connection reset by peer (104) Dec 29 10:21:09 backup stunnel[2568]: Connection reset: 192532 bytes sent to SSL, 5920666 bytes sent to socket Server: Dec 29 10:20:00 proto stunnel[30434]: 973 connected from 10.10.10.20:54054 Dec 29 10:20:00 proto rsyncd[1776]: rsync on xserve from localhost (127.0.0.1) Dec 29 10:21:49 proto stunnel[30434]: SSL socket closed with 16384 byte(s) in buffer Dec 29 10:21:49 proto stunnel[30434]: Connection reset: 5953434 bytes sent to SSL, 98416 bytes sent to socket Dec 29 16:21:49 proto rsyncd[1776]: rsync: writefd_unbuffered failed to write 4096 bytes: phase "unknown": Connection reset by peer Dec 29 16:21:49 proto rsyncd[1776]: rsync error: error in rsync protocol data stream (code 12) at io.c(666) Note that the client gets the 'connection reset by peer' a good 40 seconds before the server notices the disconnect. Here are the associated stunnel.conf's, which are pretty basic Client: cert = /etc/stunnel/backup.crt key = /etc/stunnel/backup.key setuid = stunnel setgid = stunnel pid = /var/run/stunnel/stunnel.pid socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 client = yes [8001] accept = 8001 connect = 10.10.10.15:973 Server: cert = /etc/stunnel/proto.crt key = /etc/stunnel/proto.key setuid = stunnel setgid = stunnel pid = /var/run/stunnel/stunnel.pid socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 [973] accept = 973 connect = 127.0.0.1:rsync Both are using: stunnel 4.09 on i686-pc-linux-gnu PTHREAD+POLL+IPv6+LIBWRAP with OpenSSL 0.9.7e 25 Oct 2004 Global options cert = /etc/stunnel/stunnel.pem ciphers = ALL:!ADH:+RC4:@STRENGTH debug = 5 key = /etc/stunnel/stunnel.pem pid = /var/lib/run/stunnel.pid RNDbytes = 64 RNDfile = /dev/urandom RNDoverwrite = yes session = 300 seconds verify = none Service-level options TIMEOUTbusy = 300 seconds TIMEOUTclose = 60 seconds TIMEOUTconnect = 10 seconds TIMEOUTidle = 43200 seconds Both of these machines are Gentoo 2005.1, updated to current, using the hardened 2.6 profile. Neither of them use non-standard make flags. Does anyone have some insight? There shouldn't be any "peer" (besides themselves) in the way between these two boxes to disconnect them. _______________________________________________ stunnel-users mailing list stunnel-users(a)mirt.net http://stunnel.mirt.net/mailman/listinfo/stunnel-users

stunnel library inconsistencies
by Brian T 29 Dec '05

29 Dec '05

Hi, I've been using stunnel 4.08 on an embedded Linux platform for a while now, and am attempting to move to the 2.6 kernel from the 2.4.20, which has changed my building platform. I am cross-compiling with libs and tools targeted for the embedded system, which is an i486 type AMD Elan chip. I have tried 4.08, 4.14 and 4.15b, all with the same result. Everything looks to compile properly, but when running stunnel I get the following: Inconsistency detected by ld.so: dl-minimal.c: 134: realloc: Assertion `ptr == alloc_last_block' failed! strace doesn't supply any helpful information. I have tried building with and without tcpwrappers, and have tried libssl 0.9.7g and 0.9.7i. Libssl v0.9.8a doesn't seem to play very nice. Anyone able to look at my config.log? It's 140k uncompressed, but will zip it up if needed. Thanks, -Brian

./configure issues

I'm running a fresh install of Solaris 10-sparc, and am having a helluvatime getting stunnel to configure. I come from a Gentoo background, where compiling apps is second nature, and I'm not used to this kind of problem! I originally installed gcc3.3.2 using the sunfreeware package, and as an afterthought went back again using pkg-get to make sure I had all the dependencies I needed. When I run ./configure, it errors out: # ./configure configure: **************************************** initialization checking for a BSD-compatible install... /opt/sfw/bin/ginstall -c checking whether build environment is sane... yes checking for gawk... gawk checking whether make sets $(MAKE)... yes checking build system type... sparc-sun-solaris2.10 checking host system type... sparc-sun-solaris2.10 checking for gcc... gcc checking for C compiler default output file name... a.out checking whether the C compiler works... yes checking whether we are cross compiling... no checking for suffix of executables... checking for suffix of object files... o checking whether we are using the GNU C compiler... yes checking whether gcc accepts -g... yes checking for gcc option to accept ANSI C... none needed checking for style of include used by make...

stunnel connect success even if remote side do not exist
by Nadav, Erez 28 Dec '05

28 Dec '05

i have a question: I conbfigure the stunnel to work as tcp wrapper. I configure stunnel for accept on 2003 and connect to 10.1.1.1:2003 (not exist address). I see that any TCP connect to 2003 always succeed. I expect that the TCP connect will fail if the remote side connection failed. Is there a way to make it happen Nadav Erez R&D Verint Systems Inc Phone: +972+9-9624753 Cellular: +972-54-7784753 Email: Erez.Nadav(a)verint.com Web: www.verint.com <http://www.verint.com/> __________________________________________________________________________________________ This electronic message contains information from Verint Systems, which may be privileged and confidential.

(Other) client to stunnel server 4.14
by Jurgen Tessers 24 Dec '05

Hi all, I'm in a situation where Biztalk has to communicatie through Stunnel with a broker on a other site (both on Win XP). Now the only way to reach this broker is through a proxy, and that seems the problem with Stunnel, you can't configure a proxy. Is there another way, or another client that have the possibility to configure a proxy and can connect to a Stunnel server. With regards, Jurgen

Can not estabilish stunnel
by McDouglas 13 Dec '05

Hi, I have difficulties setting up a tunnel between two linux box I administrate. Right now its only in test phase, i would like to make an stunnel connection to the smpt server at 195.56.52.140. My final goal is to set up syslog through stunnel, thats why the port name/numbers. Config file for the server: cert = /usr/local/etc/stunnel/stunnel.pem pid = /usr/local/etc/stunnel/stunnel.pid socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 debug = 7 output = /usr/local/etc/stunnel/stunnel.log [ssyslog] accept = 195.56.52.140:2514 connect = 10.10.2.1:25 Config file for the client: cert = /usr/local/etc/stunnel/stunnel.pem pid = /usr/local/etc/stunnel/stunnel.pid socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 debug = 7 output = /usr/local/etc/stunnel/stunnel.log client = yes [ssyslog] accept = 2514 connect = 195.56.52.140:2514 I get the following messages in the logs after, executing a "telnet 127.0.0.1 2514" command at the client machine (of course, smtp works on the other side, and i set iptables to allow incomming connections on 2514 dport) Server: 2005.12.13 09:09:22 LOG5[11505:1]: stunnel 4.14 on i686-pc-linux-gnu UCONTEXT+POLL+IPv4 with OpenSSL 0.9.7e 25 Oct 2004 2005.12.13 09:09:22

stunnel closing on first packet
by justin alexander 11 Dec '05

11 Dec '05

I have a client application on a windows machine, which tunnels through stunnel v4.14 to launch and inetd through stunnel v4.09 on a Linux box. The Linux side INETD successfully sends a packet of 25B to the client. The client (windows) receives this packet and returns a 12B packet. The packet IS received by the INETD but then stunnel immediately closes the socket. Why is it doing this? I'm including all configs and longs.

windows stunnel
by Noel Sanchez 09 Dec '05

09 Dec '05

Hello List. What I'd like to do is use stunnel on a Windows server behind the firewall then forward the data that comes in to the Windows server to another machine (another public ip behind the firewall) that's running an app that needs the original data. For example, I have a device out in the field that is using ssl to send data on port 4000 to my server in the office that has stunnel installed and listens on port 4000. Once the data is sent to the Windows server using stunnel, I'd like the Windows server to send the data to another computer that needs it but that doesn't have stunnel on it. The encryption will happen from the field device to the Windows server in the office, then that Windows server will have to forward the data to another computer that needs the data. I am at a lost on how to do this if at all possible. Any help would be great! Device using ssl out in the field sending data on port 4000---------firewall forwarding traffic from port 4000 to Windows server running stunnel behind firewall-----------Windows server receives stunnel data then forwards to another computer-------system that needs data---- Regards

Re: Windows config with both SSL listen and non-SSL listen
by Han Jun Li 08 Dec '05

Paul, This is a temporary solution but it works. What you need to do is run two instances of Stunnel--one instance configured in client mode and the other in server mode. If you want to run both as services, you can install the standard one with the "-install" switch. For the second instance, you need to use some other binary to install it with a different name and change the imagepath to point to the executable. /han >_____ > >From: stunnel-users-bounces(a)mirt.net [mailto:[email protected]] >On Behalf Of Paul Hethmon >Sent: Wednesday, December 07, 2005 2:50 PM >To: stunnel-users(a)mirt.net >Subject: [stunnel-users] Windows config with both SSL listen and >non-SSLlisten > > >I'm trying to set up using the Windows service the ability to listen in SSL >mode on one port (5102) and forward to non-SSL port (5010) and then also >listen on one port (5101) in non-SSL mode and forward to a remote port >(5102) in SSL mode.

Michal, Ok, the next obvious questions then: 1. When is 4.15 expected? 2. If not in the next 7 days, what can I do to help? I've done C/C++ and sockets for the last 10 years. I've looked at the code briefly so far, but have not set up a build environment yet. I need it in the next week so if there is any coding I can do which would help you, let me know your thoughts and where to put stuff. Also, just a public thanks for putting the package together. I started coding my own a couple of days ago and then thought there must have been someone else who just needed an SSL tunnel (and not a full blown SSH setup).

Server connecting back to client?
by Joshua Kugler 02 Dec '05

02 Dec '05

I've looked through the man pages, FAQ's, examples, and found one post (without a reply: http://stunnel.mirt.net/pipermail/stunnel-users/2005-May/000487.html) about this, but still don't have my question answered. I have a machine outside the firewall (let's call it outThere) that needs to connect back to a machine inside the firewall (let's call in inHere) for backup procedures. Now, because of the firewall, outThere cannot connect to inHere, but inHere can connect to anything on outThere that it wants. Can I initiate an stunnel connection from inHere to outThere, and then have stunnel on outThere listen on a localhost port, which, when connected to, would actually forward the connection (over SSL) back to a configured port on inHere? Is this at all doable? j----- k----- -- Joshua Kugler CDE System Administrator http://distance.uaf.edu/

Stunnel sending ICMP packet at startup
by Paul Jones 30 Nov '05

30 Nov '05

Hi there, I have set up Stunnel on both the server and the client. There is a firewall on the server side that only allows TCP connections through. When Stunnel is started up on the client side, the firewall is actually receiving an ICMP packet, not a TCP. Is this how Stunnel should be working? I assume it's doing a ping or something at startup. Thanks in advance. Paul _________________________________________________________________ SEEK: Over 80,000 jobs across all industries at Australia's #1 job site. http://ninemsn.seek.com.au?hotmail

My stunnel client must start without user intervention. So I installed stunnel in client mode in a Windows XP Home computer as XP service. In XP Proffesional I can specify that only Administrators group has access to stunnel directory. XP Home does not have security tab in folder properties. Any person working in XP Home compter can copy stunnel private key How to protect private key from copying ? Andrus.

Call for Beta Testers: Tool similar to Stunnel.
by Wilfred Nilsen 22 Nov '05

22 Nov '05

We have designed a tool that is similar to Stunnel and we would like to know if anyone would be interested in testing the tool. A short introduction: The Barracuda HTTPS tunnel allows you to encrypt arbitrary TCP connections inside SSL. The HTTPS tunnel allows you to secure non-SSL aware services such as TELNET, FTP, VNC, etc., by having the HTTPS tunnel provide the encryption. The HTTPS tunnel can also be used, for example, to tunnel traffic out from behind a restrictive firewall/proxy that only allows outgoing HTTPS web connections. The client is a Java program that can either be downloaded and started from the command prompt or started using Java Web Start. The server is BarracudaDrive. http://barracudaserver.com/examples/BarracudaDrive/ We will make the beta program (the server and client) available if anyone is interested in testing the tool and give us feedback. We are specifically interested in beta testers that are behind a restrictive company proxy. Thanks, Wilfred

Re: [stunnel-users] Problem with Stunnel Working fine on the firstconnection and not on subsequent connections
by Kevin A. McGrail 19 Nov '05

19 Nov '05

> I'd try to disable chroot and run stunnel under strace with "foreground = yes" option. Mike, When running in foreground, with or without chroot, things work as expected. Without foreground, it did not work. Two key differences on the logs for each: Output of "Cleaning up the signal pipe" prior to checking the libwrap permissions a finish line of "ssmtp finished (0 left)" instead of "ssmtp finished (-1 left)" (Yes, this is a dual processor box.) It looks like the key problem lies in the regerenation of the standalone mode. Is there a way with v4 to just use inetd to answer on port 465, negotiate and connect on port 25 on another host because perhaps that will avoid the issue.

Problem with Stunnel Working fine on the first connection and not on subsequent connections

Have worked on this all day without any glimmer of hope and would appreciate help and feedback! Regards, KAM # Description of your problem. What programs are on which machines, and how are they attempting to communicate. What connections are you attempting to secure in SSL. I am having problems with the regeneration of stunnel on an old but fairly reliable machine. I am switching from v3 to v4 and it works absolutely perfectly ONCE. The second time it just hangs. # What version of Stunnel you're using - remember, Stunnel 4.x doesn't take Stunnel 3.x command line options! 4.x # The list of parameters you are using for stunnel, and if you are running it standalone or from inetd/xinetd.

Stunnel Session Hangs
by Zachariah K Zachariah 17 Nov '05

17 Nov '05

Hi folks, I use stunnel-4.12 with openssl-0.9.7g to tunnel my CVS-pserver protocols. I have set up the local stunnel client to listen to port 22400 and to forward any connections on it to the cvs server that has the server side stunnel listening on port 22401 forwarding connections to the cvs-pserver on port 2401. Having set up thus, I can do a cvs login just fine. I can watch the negotiation happening using tcpdump. However when I try to check out a module from the repository, I see some files coming through but only to eventually hang. If I <Ctrl C> and try again, more files come in but hangs before the transaction is complete. I have to do this several time in order to download all the files to my local workspace. Upon checking the logs, I find that the hang occurs immediately after the message: 2005.10.28 14:21:53 LOG7[15095:67]: SSL_read returned WANT_READ: retrying 2005.10.28 14:21:53 LOG7[15095:67]: SSL_write returned WANT_WRITE: retrying 2005.10.28 14:21:53 LOG7[15095:67]: SSL_read returned WANT_READ: retrying I have included a snippet of the log file for reference. I have also included my stunnel.conf file. Sorry for the voluminous output. Can some one help me here?

Visual studio compilation errors

Hi, After browsing all previous list messages I havent found information about an error I get compiling stunnel with visual studio. The errors appear in linking step with undefined symbol message: "undefined symbol: LNK2019 undefined symbol _exit_stunnel referenced in function _main_initialize". I also attach the Makefile.w32 changed to work with visual studio. Thanks in advance. Regards, Jorge.

more stunnel problems
by Louis Young 10 Nov '05

10 Nov '05

Hi guys Ok, as I've said in a previous mail, I'm now merely trying to get the linux client to work. In the config file: [ssmtp] accept = 465 connect = 25 But now: louislaptop:/usr/local/etc/stunnel # telnet localhost 25 Trying 127.0.0.1... Connected to localhost.

Have no machine to test this. Sorry, my patch contained a bad error: ctx->stack+=STACK_SIZE-8 is, of course, nonsense, since ctx->stack must not be changed. My patch to version 4.15b1 should read instead: *** sthreads.c.15b1 Wed Nov 9 12:18:18 2005 --- sthreads.c Wed Nov 9 17:07:57 2005 *************** *** 78,85 **** return NULL; } ctx->ctx.uc_link=NULL; /* it should never happen */ ! ctx->ctx.uc_stack.ss_sp=ctx->stack; ! #if defined(__sgi) || (defined(CPU_SPARC) && ( \ defined(OS_SOLARIS2_0) || \ defined(OS_SOLARIS2_1) || \ defined(OS_SOLARIS2_2) || \ --- 78,84 ---- return NULL; } ctx->ctx.uc_link=NULL; /* it should never happen */ ! #if defined(CPU_SPARC) && ( \ defined(OS_SOLARIS2_0) || \ defined(OS_SOLARIS2_1) || \ defined(OS_SOLARIS2_2) || \ *************** *** 88,96 **** defined(OS_SOLARIS2_5) || \ defined(OS_SOLARIS2_6) || \ defined(OS_SOLARIS2_7) || \ ! defined(OS_SOLARIS2_8))) !
