ssh - connection refused

[frmas]

Hi,
I've tried to connect my office computer (client) to my home computer
(server), using ssh, but I always have the same message returned when I
run : ssh 85.201.23.11 -p 5317
"ssh: connect to host 85.201.23.11 port 5317; Connection refused".

When I restart ssh from my home computer (server), I have always the
same error message in the auth log file :
Jan 16 22:34:45 serv sshd[12379]: error: Bind to port 5317 on 0.0.0.0
failed: Address already in use.
(I don't use port 22, and here port 5317 is not the one I use really
;-)), it 's just for the purpose of that message.

This is my /etc/ssh/sshd_config file

Where could be my mistake ? Thanks. Francois
