Hello,

I'm debugging with openssl s_client...

From inside the box:

$ openssl s_client -connect blackshell.usebox.net:995 CONNECTED(00000004) depth=0 /C=ES/ST=Valencia/L=Valencia/O=usebox.net/OU=blackshell/CN=blackshell.usebox.net verify error:num=18:self signed certificate verify return:1 depth=0 /C=ES/ST=Valencia/L=Valencia/O=usebox.net/OU=blackshell/CN=blackshell.usebox.net verify return:1 ...

And works fine.

From outside:

$ openssl s_client -connect blackshell.usebox.net:995 CONNECTED(00000003)

(and halts for n minutes)

I hope this helps, even I don't know the difference between "CONNECTED(00...4)" and "CONNECTED(00...3)".

Regards,

Juanjo
