Client Authentication and CRL Verification
by Mehdi B. 02 Dec '15

02 Dec '15

Hello everybody I am using stunnel in server mode with mutual authentication. Auth is ok, but the crl didn't work, and I need it in production next week.... I do many tries with CRLpath/CRLfile, with my production version (5.08), the last one (5.26) Same result. With a revoked certificate, my client connect on the server. Do you have some idea? Or maybe found my mistake? If you need something else please contact me. Stunnel 1 is the server. Stunnel 1 certificate is revoked ** Configuration ** *** root@auditd:/var/lib/stunnel/2/ca# cat /etc/stunnel/1.conf *** ; * Global options * chroot = /var/lib/stunnel/1/ ; Chroot jail can be escaped

Failover behavior with stunnel
by Thireus 30 Nov '15

30 Nov '15

Hi, I have a couple of questions regarding failover with stunnel: 1. I would like to know if there is a way to use failover with two servers with two different set of TLS cert/key. The following rule doesn't work, because the cert and key parameters are overwritten, but it shows what I would like to achieve: [failover] accept = 127.0.0.1:4441 <http://127.0.0.1:4441/> cert = cert_1.cert key = key_1.pem connect = server-1:1234 cert = cert_2.cert key = key_2.pem connect = server-2:1234 2. On the same topic, I would like to know if there is an option that could open the local port (accept) only when the connection (connect) is established? The problem I'm facing is that I use a PAC profile with failover on several stunnel entries: "return PROXY 127.0.0.1:4441 <http://127.0.0.1:4441/>; PROXY 127.0.0.1:4442 <http://127.0.0.1:4442/>; PROXY 127.0.0.1:4443 <http://127.0.0.1:4443/>;". However, when one of the remote server is down (i.e. server-1), it is not easily detected by web-browsers (Chrome does not seem to detect it well), and so instead of switching to the next PROXY, it simply dies on the first one. If the port 4441 relative to server-1 (which is unavailable) was closed, then the webrowser could easily detect it and switch to the second server with port 4442. 3. Is there another way to tweak stunnel behavior when a remote server is down? I'm thinking about a couple of things, like being able to switch to a different rule set: [failover1] accept = 127.0.0.1:4441 <http://127.0.0.1:4441/> cert = cert_1.cert key = key_1.pem connect = server-1:1234 connect = 127.0.0.1:4442 <http://127.0.0.1:4442/> ; This is failover2 [failover2] accept = 127.0.0.1:4442 <http://127.0.0.1:4442/> cert = cert_2.cert key = key_2.pem connect = server-2:1234 Or maybe there are some options that I'm not aware of to timeout connections more efficiently: so that Chrome (or other clients using HTTP proxies) will immediately know that stunnel cannot connect to the remote server and so that the proxy is down. Thank you for your help. Cheers, Thireus.

syslog communication using TLS with the help of stunnel
by Girish Kumar 24 Nov '15

24 Nov '15

Dear All, Currently we are using syslog communication without any security. That is using UDP protocol with the server listening on port number 514. This is unsecure. I want to use syslog over TLS that is over TCP . As of now in my project syslogd daemon is used. I am planning to use stunnel to achieve this. I have few questions. Please clarify * To support stunnel, syslogd should be on TCP and not on UDP? * Is stunnel is a daemon ? * My understanding is syslogd forwards messages to the stunnel local portal at port 61514. The local stunnel forwards data via the network to port 60514 to its remote peer. * I assume stunnel-5.26(stunnel-5.26.tar.gz) is the latest version and this can be used on linux Regards, Girish
