syslog on Solaris2.9
by Geoff LeBoldus 13 May '05

13 May '05

I can't seem to get stunnel-4.10 to log properly to syslog. Stunnel logs the startup, but doesn't log any individual tunnel information. If I specify its own file and debug = 7, it logs everything as expected. I've tried a number of different configuration combinations without success. Any thoughts? Here's my current config snippets - stunnel.conf debug = local0.debug -syslog.conf local0.debug /var/log/syslog Stunnel startup from /var/log/syslog May 13 15:31:31 server_name stunnel[4576]: [ID 702911 local0.notice] stunnel 4.10 on sparc-sun-solaris2.9 UCONTEXT+POLL+IPv4 with OpenSSL 0.9.7f 22 Mar 2005 May 13 15:31:31 server_name stunnel[4576]: [ID 702911 local0.notice] stunnel 4.10 on sparc-sun-solaris2.9 UCONTEXT+POLL+IPv4 with OpenSSL 0.9.7f 22 Mar 2005 May 13 15:31:31 server_name stunnel[4576]: [ID 702911 local0.debug] Snagged 64 random bytes from /home/geoff/.rnd May 13 15:31:31 server_name stunnel[4576]: [ID 702911 local0.debug] Wrote 1024 new random bytes to /home/geoff/.rnd May 13 15:31:31 server_name stunnel[4576]: [ID 702911 local0.debug] RAND_status claims sufficient entropy for the PRNG May 13 15:31:31 server_name stunnel[4576]: [ID 702911 local0.info] PRNG seeded successfully May 13 15:31:31 server_name stunnel[4576]: [ID 702911 local0.debug] Certificate: /opt/local/etc/stunnel/stunnel.pem May 13 15:31:31 server_name stunnel[4576]: [ID 702911 local0.debug] Key file: /opt/local/etc/stunnel/stunnel.pem May 13 15:31:31 server_name stunnel[4576]: [ID 702911 local0.info] file ulimit = 1024 (can be changed with 'ulimit -n') May 13 15:31:31 server_name stunnel[4576]: [ID 702911 local0.info] poll() used - no FD_SETSIZE limit for file descriptors May 13 15:31:31 server_name stunnel[4576]: [ID 702911 local0.notice] 500 clients allowed May 13 15:31:31 server_name stunnel[4576]: [ID 702911 local0.notice] 500 clients allowed May 13 15:31:31 server_name stunnel[4576]: [ID 702911 local0.debug] FD 5 in non-blocking mode May 13 15:31:31 server_name stunnel[4576]: [ID 702911 local0.debug] FD 6 in non-blocking mode May 13 15:31:31 server_name stunnel[4576]: [ID 702911 local0.debug] FD 7 in non-blocking mode May 13 15:31:31 server_name stunnel[4576]: [ID 702911 local0.debug] SO_REUSEADDR option set on accept socket May 13 15:31:31 server_name stunnel[4576]: [ID 702911 local0.debug] ldaps bound to 0.0.0.0:1212 May 13 15:31:31 server_name stunnel[4577]: [ID 702911 local0.debug] Created pid file /stunnel.pid May 13 15:31:31 server_name stunnel[4577]: [ID 702911 local0.debug] Waiting -1 second(s) for 2 file descriptor(s) -- Geoff LeBoldus Systems Programmer Information Technology Services

Session Reuse Information for Stunnel
by vasudha.upadhyaya＠convergys.com 11 May '05

11 May '05

I know that Stunnel reuses sessions. Can anyone tell me the default time that stunnel reuses the old session. And to set a value for session timeout do I use the option: session = timeout session cache timeout Thanks, Vasudha. -------------------------------------------- Vasudha Upadhyaya Convergys Speech Solutions Ph:703-885-5837 vasudha.upadhyaya(a)convergys.com -- "NOTICE: The information contained in this electronic mail transmission is intended by Convergys Corporation for the use of the named individual or entity to which it is directed and may contain information that is privileged or otherwise confidential.

zlib compression
by Oleg Ivanov 09 May '05

09 May '05

Hello. I have installed stunnel 4.09 both as client (on my computer) and as server (on server). Both has zlib compression enabled and I can see that zlib initializes properly in the logs (it says "Compression enabled using zlib method"). But when I send any data over that tunnel I can't see any signs of compression - amount of traffic is almost the same as over plain connection. Am I doing something wrong? Or I'm misunderstanding the purpose of this compression ability? And if the traffic indeed must be reduced - why I can't see that and how can I make it work properly? Thank you for your answers. Best Regards, Oleg Ivanov. -- Oleg Ivanov mailto: saruman(a)unigsm.com

connect ip = accept ip on multihomed server ?
by Dennis Spreen 09 May '05

09 May '05

hi all, with a configuration (stunnel4.10) like this [conc1] accept = 100 connect = 99 stunnel accepts all requests on all ips on port 100 but connects with the localhost to port 99. is it possible to configure stunnel that if it accepts a connection on 1.2.3.4:100 it connects to 1.2.3.4:99 ? I know it is possible to use accept = 1.2.3.4:100 connect = 1.2.3.4:99 .... accept = 1.2.3.250:100 connect = 1.2.3.250:99 but i'm on a c-class and that would require about 250 entries in the config file. Is there a better way to do this? regards dennis

Problems in Stunnel4.10
by vasudha.upadhyaya＠convergys.com 06 May '05

06 May '05

Hi, We have been using stunnel 4.05 and recently downloded the stunnel 4.10 and deployed in our environmrnt. All the traffice is going via the Load Balancer Cisco CSS with SSL Module to the unix server(with stunnel4.10 on them). We also 4.10 deployed on the Windows2000 as a client. The CSS sends keep Alives to check the health of the servers(whether they are up or not).And I guess due to this the stunnel on unix servers crashes immediately and there is a access violation error. Attached is the truss output for one of the unix servers.Stunnel4.10 was compiled using OpenSSL0.97d and OpenSSL0.97g, and still we get the same problem.Attached is the stunnel.conf also.[attachment "stunnel.conf" deleted by Vasudha Upadhyaya/CCMG/CVG] (See attached file: truss.out) (See attached file: stunnel.conf) Thanks, Vasudha. -------------------------------------------- Vasudha Upadhyaya Convergys Speech Solutions Ph:703-885-5837 vasudha.upadhyaya(a)convergys.com -- "NOTICE: The information contained in this electronic mail transmission is intended by Convergys Corporation for the use of the named individual or entity to which it is directed and may contain information that is privileged or otherwise confidential.

Does anyone have a good link to setting up qmail to use stunnel for pop3s? I have found a few, but so far nothing seems to work from me.

Newbie windows user needs help patching/compiling with mingw
by Geoff Elmer 04 May '05

04 May '05

Can anyone point me to some documentation on how to use mingw to patch and make stunnel? Specifically, I want to apply connect-proxy_dunbar.patch to v4.05 source and compile it. As I am not really a coder (yet) and am not yet very *nix knowledgeable, any help would be much appreciated. Situation is: I am trying to traverse a MS ISA server (running as a proxy) and the v4.10 stunnel doesn't allow me to specify a proxy to route thru. Thanks in advance, Geoff __________________________________ Do you Yahoo!? Yahoo! Mail - Find what you need with new enhanced search. http://info.mail.yahoo.com/mail_250

I have compiled and installed stunnel 4.10 under Mac OS X 10.3. I want to set up stunnel to connect a non-ssl newsreader client to an ssl nntp server. The newsreader client is Unison and the server is Easynews SSL server. I don't really know how to do this. I wonder if anyone can point me in the right direction. Thanks Geoff ___________ PS I did various searches of the list archive and read TFM, but still need guidance!

ldaps error "unknown protocol"
by Mike Partyka 29 Apr '05

29 Apr '05

Hello, Description of problem is as follows: I have a email server package called Scalix, which when installed came with openldap. On the same server i am also running Stunnel, which is already successfully ssl wrapping imap,pop, and smtp protocols. The ldap directory is very handy for an address book internally but we also have people that will be outside the corporate lan and to provide the directory securely would be desirable so i added the lines in the stunnel.conf to wrap ldap as well. I can see the stunnel daemon listening on port 636. But when i try to connect from any ssl aware mail client, such as evolution, or entourage, i get an error indicating failure to authenticate, which i know is not really the problem because the ldap directory is anonymous read access enabled. Debug logging gives more information about what is occurring, here is the conversion when attempting to connect: 2005.04.28 12:15:05 LOG5[27926:1076812720]: ldaps connected from 71.4.124.200:43012 2005.04.28 12:15:05 LOG7[27926:1076812720]: SSL state (accept): before/accept initialization 2005.04.28 12:15:05 LOG7[27926:1076812720]: waitforsocket: FD=14, DIR=read 2005.04.28 12:15:05 LOG7[27926:1076812720]: waitforsocket: ok 2005.04.28 12:15:05 LOG3[27926:1076812720]: SSL_accept: 140760FC: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol 2005.04.28 12:15:05 LOG7[27926:1076812720]: ldaps finished (6 left) Searching the archive is saw someone suggesting that either the ldap server or ldap client was not compiled with ssl support. I know the email clients i am trying to connect with are ssl compatible and maybe someone can set me straight here but i didn't think that the ldap server had to be ssl aware and that was the advantage of stunnel is that it can wrap services that are do not have ssl support? At any rate i believe the ldap server does have ssl support becuase i can see the binary omslapd (provided by Scalix, preceding "om" is there because Scalix is based on HP's Open Mail) links to the
