Hi Jose,

Thanks for mail. The problem is that when I change the accept port on the
server, stunnel doesn't start:



accept = 2404
connect = 2406


client = yes
accept =
connect = *my_server_name*:2406


I edited the stunnel.conf on the server:

accept = 2406
connect = 2406

Then trying to start the service:

*/etc/init.d/stunnel start*
*Starting stunnel (SSL tunnel) startproc:  exit status of parent of
/usr/sbin/stunnel: 1*
*  please see /var/log/rc.stunnel.log for details


/var/log/rc.stunnel.log is empty but in the log specified in the
stunnel.conf I have the following:

tail -10 /var/log/stunnel/stunnel.log

Same thing happens when I try to change the ports on the client. Any idea
how this problem can be solved?

Thanks and regards,
