Simple SMTP encryption
by James Moe 19 May '07

19 May '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 hello, stunnel 4.20 with OpenSSL 0.9.8d 28 Sep 2006 I wish have my MUA to send messages encrypted to a secure mail server. Stunnel is set up as a client with the following configuration: client = yes [smtps] accept = 127.0.0.1:465 connect = smtpauth.earthlink.net:25 I missed the part somewhere that tells Stunnel to issue a STARTTLS to the smtp server before attempting to negotiate a TLS connection. The "failed handshake" bit is because the server is rejecting the command because of NULLs in the text stream. 501 NULL characters are not allowed in SMTP commands. Then there is the "wrong version" error. I suppose that is a side effect of the handshake failure? Here is a typical connection log: 2007.05.19 12:52:42 LOG7[232:4239]: smtps accepted FD=12 from 127.0.0.1:52672 2007.05.19 12:52:42 LOG7[232:4239]: Creating a new thread 2007.05.19 12:52:42 LOG7[232:4239]: New thread created 2007.05.19 12:52:42 LOG7[264:4239]: smtps started 2007.05.19 12:52:42 LOG7[264:4239]: FD 12 in non-blocking mode 2007.05.19 12:52:42 LOG7[264:4239]: TCP_NODELAY option set on local socket 2007.05.19 12:52:42 LOG5[264:4239]: smtps accepted connection from 127.0.0.1:52672 2007.05.19 12:52:42 LOG7[264:4239]: FD 15 in non-blocking mode 2007.05.19 12:52:42 LOG7[264:4239]: smtps connecting 207.69.189.201:25 2007.05.19 12:52:42 LOG7[264:4239]: connect_wait: waiting 10 seconds 2007.05.19 12:52:42 LOG7[264:4239]: connect_wait: connected 2007.05.19 12:52:42 LOG5[264:4239]: smtps connected remote server from 192.168.69.14:52673 2007.05.19 12:52:42 LOG7[264:4239]: Remote FD=15 initialized 2007.05.19 12:52:42 LOG7[264:4239]: TCP_NODELAY option set on remote socket 2007.05.19 12:52:42 LOG7[264:4239]: SSL state (connect): before/connect initialization 2007.05.19 12:52:42 LOG7[264:4239]: SSL state (connect): SSLv3 write client hello A 2007.05.19 12:52:42 LOG7[264:4239]: SSL alert (write): fatal: handshake failure 2007.05.19 12:52:42 LOG3[264:4239]: SSL_connect: 1408F10B: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number 2007.05.19 12:52:42 LOG5[264:4239]: Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket 2007.05.19 12:52:42 LOG7[264:4239]: smtps finished (0 left) - -- jimoe (at) sohnen-moe (dot) com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (OS/2) iD8DBQFGT1lQzTcr8Prq0ZMRAv50AJ9Kydmi3F/VBQ8hvpr+HmodUZhJEgCfQjbz TRdvnzpATUH/y3gzA1EXMYo= =jTqm -----END PGP SIGNATURE-----

Several connections on a short period of time problem
by Teigao, Rafael Coninck 16 May '07

16 May '07

Hi, I'm running Stunnel 4.20 to connect a Win client to a Win server. On the server it runs as a service, but on the client side I call it every time a connection is requested with a different config file (I need dynamic configuration) If I connect, disconnect and connect again very quickly (say, in 10 seconds), the fourth time (usually) that I try to connect will give me error 10060 (timeout) on the client application (not Stunnel). Does Stunnel restrict the amount of connection from the same client based on time or something like that? Thanks, Rafael.

Looking at the stunnel window, there are no messages about any connections to the stunnel. If I do: telnet 222.222.222.222 139 the telnet session connects and I see messages about a connection in the stunnel window. Any ideas why Vista is not using port 139?
