Stunnel error
by Reinier van der Gugten 23 Feb '09

23 Feb '09

Hi, I use the STunnel tool to connect to my Ms-SQL database. And so far this works nice. However at one organization I have the following problem: << connect_wait: s_poll_wait timeout>> And the connection fails. Here is the log file and config file. Can you give me any hints how to check where it goes wrong? Thanks.

The rsync job (873) failed after the IP of the stunnel host had changed. I had to manually restart stunnel to get the job done and put the cron script back again. delay = yes does not with work with ddns. Regards, Adamson H

stunnel hanging (libwrap)
by Ulrich Wisser 11 Feb '09

11 Feb '09

Hi, on my current project I have a strange error. Stunnel will work for months and suddenly stop accepting connections. At other times it will fail after a couple of hours. It doesn't crash. Connections are still accepted, but no SSL negotiation does take place. Please find a log below. It seems to be some problem with libwrap. As you can see in the logs the last usage of libwrap doesn't release libwrap properly. "Released libwrap process" log statement is missing. And after that just everything hangs waiting for libwrap. But why is this happening? Our host.allow and host.deny files are empty. libwrap is supposed to allow everything. Any suggestions are welcome!

stunnel client connecting to host with dynamic dns service
by Adamson H 09 Feb '09

09 Feb '09

Hi, stunnel 4.26 solves a number of issues running on FreeBSD. However, a stunnel client still has a problem reconnecting to a host with dynamic DNS service after the host IP has changed. Stunnel client seems unaware of the host update, pointing the dynamic DNS name to the old outdated IP. In order to get reconnected to the host, I have to create a cron script to detect the IP change and restart stunnel on the stunnel client. My client conf file has the following: [1873] accept = 1873 connect = hostname.dynaip.org:1873 The ip of hostname.dynaip.org changes at a random interval. Please help. Adamosn H

Your understanding is not correct, but similar functionality was re-implemented from scratch. You may consider Reading The Fine Manual at: http://stunnel.mirt.net/static/stunnel.html The relevant part is: protocol = proto application protocol to negotiate SSL currently supported: cifs, connect, imap, nntp, pop3, smtp protocolAuthentication = auth_type authentication type for protocol negotiations currently supported: basic, NTLM Currently authentication type only applies to 'connect' protocol. default: basic protocolHost = host:port destination address for protocol negotiations protocolPassword = password password for protocol negotiations protocolUsername = username username for protocol negotiations Best regards, Mike

crl next update field functionality seems incorrect
by Steve Hoffman 04 Feb '09

04 Feb '09

Regarding this piece of code in verify.c: if(X509_cmp_current_time(next_update)<0) { s_log(LOG_WARNING, "Found CRL is expired - " "revoking all certificates until you get updated CRL"); X509_STORE_CTX_set_error(callback_ctx, X509_V_ERR_CRL_HAS_EXPIRED); X509_OBJECT_free_contents(&obj); return 0; /* reject connection */ } I don't believe this is correct functionality. The "next update" field is not an expiration of the CRL, but more of an indicator that you, as the holder of the CRL, should obtain a new one. Snippet from this link: http://www.netscape.ca/browser/netscape8/help/en/ssl_help.html#next_update About the "Next Update" Date The browser uses the CRLs it has available to check the validity of certificates issued by the corresponding CAs. If a certificate is listed as revoked, the browser won't accept it as evidence of identity. A CA typically publishes an updated CRL at regular intervals. Every CRL includes a date, specified in the Next Update field, by which the CA will publish the next update of that CRL. In general, if the date in the Next Update field is earlier than the current date, you should obtain the most recent version of the CRL. To view CRL information and set up automatic CRL updating, see Viewing and Managing CRLs. CAs are required to produce a new CRL by the Next Update date. However, the absence of the most recent CRL does not by itself invalidate a certificate. For this reason, if the most recent CRL is not available, a certificate may be validated even though the most recent CRL shows it as expired. Automatic CRL updating can help to avoid this situation. I'd like to suggest removing this check. Thanks, Steve
