Delay before sending server hello
by Dan Price 28 Apr '11

28 Apr '11

I am using stunnel to accept TLS connections. I'm opening eight connections at virtually the same time, and occasionally see that for one of the connections, the handshake does not complete - stunnel does not send the server hello, and the client usually resets the connection. I did manage to capture one instance where stunnel sends the server hello, but it is delayed by over a minute. I upgraded to version 4.35, and I see the same behavior. I set debug=debug, and captured what I think are the relevant logs (through write server hello). I kept the logs for the successful connection (59924) that came in after the failed one (59923).

Does stunnel support startTLS?
by Markus Borst 28 Apr '11

28 Apr '11

Stunnel supports encryption in the "old" ssl style extra port configuration (i.e. imaps on port 993) where the encryption is negotiated immediately upon start of the connection. Does stunnel also support the startTLS method? i.e. a clear text connection is established (imap on port 143) and one of the first imap commands is startTLS, which negotiates the encryption and protects the connection from that time onwards. I know that supporting startTLS is a lot harder, since it means sniffing commands in the higher level protocol, but we need it nevertheless. (In fact, our imap server does support startTLS, but it does _not_ support importing an external certificate, which is why I'm looking for an external solution.) From reading the documentation I'm not sure whether stunnel supports startTLS, there are a few option descriptions which might point to startTLS, but I'm not sure. Anybody knows the definite answer?

Thx for continuing reply my msg, Yes, there is var/log/messages Inside there only has some iptables log, FTP, SMTP application log and nothing else. I am positive that this problem is not cause by iptables, becuase I tried with iptables off. Nothing else related to stunnel is found in that folder. Any other suggestions?

Patch to enhance verify=3 with SHA-1 check
by Philipp Hartwig 27 Apr '11

27 Apr '11

As indicated in a previous mail to this list I was surprised by the following behavior: With "verify=3" stunnel doesn't compare the peer's certificate with the locally installed certificate for actual equality but it only checks whether they have the same subject. The recent Comodo incident[1] has shown that it is not impossible to get a certificate which matches the subject of the certificate of some interesting server and is signed by a trusted CA. That's why I was interested in a stricter form of verification (at least in client mode). I have attached a small patch, derived from code in the file "mutt_ssl.c" of the Mutt[2] mail client, which adds a check for equality of SHA-1 hashes to the "verify=3" certificate check. I mainly wrote it for personal use but maybe someone else will find it useful or has some comments. Regards, Philipp [1] http://blog.mozilla.com/security/2011/03/25/comodo-certificate-issue-follow… [2] http://www.mutt.org/

Those with the ".crl" extension, I suppose ;-) You'll need to look for the CRLs matching the certificates you want to use. Note, there may be CRLs for intermediate certificates too. At least (the randomly selected) Class3SoftwarePublishers.crl seems to be in DES format, you might have to convert it to PEM for use with stunnel.

If you are using verify=3, stunnel checks client certificates against the set of certificates in CApath or CAfile, not against CAs and CRLs. In order to have stunnel check the certificate chain of client certificates, you'll have to use verify=2. For that, stunnel needs access to the CA's root certificate and the intermediate certificates (i.e. they have to be locally installed to CApath/CAfile). > Secondally, i need to download and update the crl files, and also (if it's > possible) the certificates of knowed CA.

For VeriSign, my first idea is to use wget to download them from http://crl.verisign.com. There may be better ways, though. And I don't know AIX.

You could also store the client's certificates in PEM format files (one file per certificate) in a directory stunnel can reach at connection time. You have to specify the name of this directory as CApath then (in contrast to CAfile), and you'll have to run c_rehash on this directory.

Temporary failure in name resolution
by Phil Wieland 26 Apr '11

26 Apr '11

I think I've done something stupid but I can't work out what. I'm running stunnel4 version 4.29 on an Ubuntu server box, using it to tunnel smtp connections to my ISP's mail server. Everything works perfectly until I reboot the server, when it stops working. In syslog, I get: Apr 24 15:56:11 friedbread stunnel: LOG5[1101:3074997104]: ssmtp accepted connection from 127.0.0.1:50681 Apr 24 15:56:11 friedbread stunnel: LOG3[1101:3074997104]: Error resolving 'smtp.blueyonder.co.uk': Temporary failure in name resolution (EAI_AGAIN) Apr 24 15:56:11 friedbread stunnel: LOG3[1101:3074997104]: No host resolved Apr 24 15:56:11 friedbread stunnel: LOG5[1101:3074997104]: Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket every time I attempt to send mail. I can ping smtp.blueyonder.co.uk no problem. The problem persists until I restart stunnel4, after which it works perfectly for weeks on end. Looking at syslog for boot time, it looks like stunnel tries to resolve smtp.blueyonder.co.uk as soon as it starts, but dhcp hasn't finished at this time so it fails. It seems to cache something from the failure and not try again? Even though the error is "Temporary". All advice gratefully received.

I installed the 4.35 one into my CentOS, it seems like the same problem still exist. Is there anything I can do to fix it?

You can recompile the SRPM (4.29) from redhat 6 (or scientific linux 6) and it works fine under CentOS 5.
