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!

Anyone here managed to build stunnel for Irix? it seems socklen_t is undefined as a type on this OS (and also older versions of solaris). I have found a possible solution here: http://sprg.ssl.berkeley.edu/~fastops/ITOS/portable/socklen$_t.html but I need to know what type this identifier is supposed to be. any help?

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

I'm NOT going to break SSL protocol in stunnel to support broken SSL clients. Use: TIMEOUTclose = 0 configuration option instead. Best regards, Mike

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?
