Processing during CRL expiry and refresh
by Nagasundaram, Sekhar 06 Jun '06

06 Jun '06

All: I have 2 questions: 1. Is there a way to have Stunnel continue processing and accepting connections after the CRL expiry? Currently it gives a "revoking all certificates" error and stops accepting connections. 2. Is there a configurable parameter through which we can have the CRL list refresh itself such that 1 above does not happen? Much Thanks in advance.. Sekhar

unsecure configuration
by Robert Bator 01 Jun '06

01 Jun '06

Hi , I am trying to set up stunnel to accept unsecure calls on port 1001 from inside and secure calls on port 1000 from internet. All calls are forwarded to machin B The configuration like this: secure --> 1000 machine A unsecure --> 1002 machine B unsecure --> 1001 machine A unsecure --> 1002 machine B Is this setup possible i stunnel? PS. I use "stone repeater" and this rules are easy to setup. Best Regards, Robert Bator

stunnel and bad rsa signature
by Trent Townsend 30 May '06

30 May '06

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 On a test environment, I successfully had stunnel securing MySQL traffic between 2 systems using a verify level of 3. However, with the production system and what I would call an identical setup (albeit with new certificates), I get the following errors (see log below.) The version I'm running of stunnel is 4.11. I saw the "bad rsa signature" message in the server's output, so I regenerated the private key file to be sure I'd used the right one. Everything seems to be in order, but it will not work. Any ideas?

Problem getting stunnel to chroot on Suse 10
by Paul Stepowski 29 May '06

29 May '06

Hi list, I'm using stunnel package that comes standard with Suse 10.0 stunnel 4.10 on i686-suse-linux-gnu UCONTEXT+POLL+IPv4+LIBWRAP with OpenSSL 0.9.7g 11 Apr 2005 I can tunnel ports over ssl using stunnel but the chroot directive doesn't seem to be working. E.g. my pid file is being created under / rather than /var/lib/stunnel-syslogng. The other paths in the config file are taken by stunnel as relative to / rather than the chroot directory. What am I missing? Here's my stunnel config. I'm not passing any other flags when running stunnel. ---snip--- client = no #debug = 7 #foreground = yes chroot = /var/lib/stunnel-syslogng setuid = stunnel setgid = nogroup pid = /stunnel.pid #output = stunnel.log socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 #compression = rle #options = DONT_INSERT_EMPTY_FRAGMENTS #verify = 2 #CApath = /certs #CAfile = /certs/stunnel.pem #CRLpath = /crls #CRLfile = /etc/stunnel/crls.pem cert = /var/lib/stunnel-syslogng/certs/stunnel.pem ---snip--- Thanks, Paul

The first, successful (!) call to run_client() seems to leave the ssl context in an undefined state which makes the following calls to run_client() segfault in the forked child which in turn produces the core file. My guess is, that it's not actually supposed to loop if the call to run_client() is successful. Reverting client.c to roughly 4.14 fixes the problem for me. A patch is attached. Any insights and a more permanent fix would be highly appreciated. BTW: I configured stunnel with --with-threads=pthread. By default, ucontext is detected, which is broken in stunnel-4.14 as well. After finishing, 4.14 hangs in s_poll_wait waiting for -1 seconds on 0 fds (!?). I can provide debugging log and gdb output if needed. -- bye, Michael

Using a signed *.domain.com with ssl - Getting "unable to get local issuer certificate"
by Pritesh Mehta 24 May '06

24 May '06

Hello all, I have had a good hunt around and am having trouble finding a solution. I am using stunnel to provide encrypted pop3 access to our mail server, and we have recently purchased a signed *.XXX.com certificate from godaddy. This has been great since I can use the same cert on all our servers, and this has worked cleanly with the webservices. However, I am having some issues with the stunnel and pop3 service. I am not entirely certain whether it is caused by the *.XXX.com certificate (although I think it unlikely) but was hoping someone more knowledgeable could enlighten me? I currently have stunnel configured thusly: stunnel -f \ -A /etc/stunnel/certs/sf_issuing.pem \ -p /etc/stunnel/certs/wildcard.XXX.com.stunnel.pem \ -r 127.0.0.1:110 Unfortunately my users are getting warnings, and using the openssl client I get: $ openssl s_client -connect mail.XXX.com:995 CONNECTED(00000003) depth=1 /C=US/ST=Arizona/L=Scottsdale/O=Starfield Technologies, Inc./OU=http://www.starfieldtech.com/repository/CN=Starfield Secure Certification Authority/emailAddress=practices(a)starfieldtech.com verify error:num=20:unable to get local issuer certificate verify return:0 --- Certificate chain 0 s:/O=*.XXX.com/OU=Domain Control Validated/CN=*.XXX.com i:/C=US/ST=Arizona/L=Scottsdale/O=Starfield Technologies, Inc./OU=http://www.starfieldtech.com/repository/CN=Starfield Secure Certification Authority/emailAddress=practices(a)starfieldtech.com 1 s:/C=US/ST=Arizona/L=Scottsdale/O=Starfield Technologies, Inc./OU=http://www.starfieldtech.com/repository/CN=Starfield Secure Certification Authority/emailAddress=practices(a)starfieldtech.com i:/L=ValiCert Validation Network/O=ValiCert, Inc./OU=ValiCert Class 2 Policy Validation Authority/CN=http://www.valicert.com//emailAddress=info@valicert.com --- Server certificate -----BEGIN CERTIFICATE----- [snip] -----END CERTIFICATE----- subject=/O=*.XXX.com/OU=Domain Control Validated/CN=*.XXX.com issuer=/C=US/ST=Arizona/L=Scottsdale/O=Starfield Technologies, Inc./OU=http://www.starfieldtech.com/repository/CN=Starfield Secure Certification Authority/emailAddress=practices(a)starfieldtech.com --- No client certificate CA names sent --- SSL handshake has read 2381 bytes and written 340 bytes --- New, TLSv1/SSLv3, Cipher is AES256-SHA Server public key is 1024 bit Compression: NONE Expansion: NONE SSL-Session: Protocol : TLSv1 Cipher : AES256-SHA Session-ID: 4E550C07BDA9661C4B532A28110E5616549CB9FA72D37E5C979E3C6579F8FB99 Session-ID-ctx: Master-Key: 2E588101AA098463FA40C0353009F5842FA19B1C3D48D9A0000EB2E241EFB70BB10D52FE9BC444344D49653B9FEB25F4 Key-Arg : None Start Time: 1148463445 Timeout : 300 (sec) Verify return code: 20 (unable to get local issuer certificate) --- I am positive this must have been covered before somewhere, but I haven't been able to find anything conclusive.

<Stunnel> multiple connection
by aliquippa1 23 May '06

23 May '06

Hello I have problem with stunnel. I want to use feature which I'm not sure if is available. I want to accept connection from a host and then connect to a few hosts. I want to have something like this: accept = xxx.xxx.xxx.xxx:xxxx connect = yyy.yyy.yyy.yyy:yyyy connect = zzz.zzz.zzz.zzz:zzzz connect = vvv.vvv.vvv.vvv:vvv Now I want to get such situation: 1.accept connection from xxx. 2.try to connect to yyy. 3 if it doesn't work try to connect to zzz. 4 if it doesn't work try to connect to vvv. I wonder if it's possible, because if I use stunnel and connect from xxx it connects me only to the first host and when I connect from xxx again it connects me to the second host and after the third trial from xxx it connects me to vvv. Thanx Agnes

stunnel-4.15 segfaulting and looping under FreeBSD-CURRENT

Hi, I've run into the problem mentioned in: > Scott Tuc Ellentuch at T-B-O-H ml at t-b-o-h.net > Fri Apr 21 23:45:11 CEST 2006 > Hi, > I just did a portupgrade in FreeBSD from 4.14 to 4.15, and now it > seems to be looping the command that I asked it, instead of just doing > it once. Has there been an option added I need to tell it to just do > once? > Thanks, Tuc I'm running stunnel in client mode. It execs uucico which receives and sends uucp jobs via stdin/stdout. The first call to uucico actually succeeds. It seems like stunnel is segfaulting and then re-exec-ing when it would normally quit. A core file is created in the current directory. But stunnel never quits and indefinitely continues to re-exec itself. Has there been any progress in solving this problem? -- Thanks, Michael

Thanks a lot! Craig. I use your method: ./configure --prefix=/stunnel2 It seems that installation is successful. It successfully generate a directory ./stunnel2, in which there are six subdirectories: etc lib man sbin share var But when I run stunnel command in the teminal window. It does not take it as a command. Is it supposed to run stunnel command after the installation or not? Is there anything missing in the Mac machine before it can run stunnel?

Hi, I want to install Stunnel 4.15 into MAC OS X machine. Somehow I do not have the right to make any directory in /usr so I can not install Stunnel in /usr/local. How do I install Stunnel into different directory? Thanks Peng

SSL2Proxy
by Steve Cohen 12 May '06

12 May '06

Hello all, I'm tyring to get around content based(notHostBased) int*rn*t cen$0ring. (don't want this page to be indexed with that keyword, so please don't wite it in your response). This is what I need to do: Set Browser on client machine to use <proxyX:port>, but I want content to be encrypted. The proxy is trusted(ownedByMe), everything else in between is not, after the proxy everything is trusted. So this would be the setup: SetupA: ClientBroswer <> STunnelOnRemoteServer <> LocalProxyServerOnSameServer(Squid) <> RestOfTheInternet And NOT this: SetupB: Browser<>LocalSTunnel<>RemoteSTunnel<>Proxy<>RestOfTheInternet Because I don't want any special kind of configuration on the client's local machine except for setting the proxy.(I am currently doing this via ssh tunneling) -I have squid running on remote server listening on 3128 and it works -I have stunnel running on remote server listening on 8686 and forwarding to localhost:3128, -I have Firefox set to use <myServer:8686> as proxy But when trying to use it, Firefox says connection reset.... Please tell me why this is happening and what I need to do. Feel free to make any suggestions you want, I won't be annoyed if you tell me something I already know. Thanks.

Assuming you mean over a channel that starts of plaintext and is later converted to encryption, the command to start TLS is usually specific to the application protocol. What protocol are you using?
