SSH connection timed out from only one client

ssh

I'm facing problem with only one machine A which can't get connected to another remote machine B through ssh.

This is what I do when I try to connect with ssh from A to B : 

ssh root@92.39.xxx.xxx -vvv
OpenSSH_5.5p1 Debian-6+squeeze2, OpenSSL 0.9.8o 01 Jun 2010
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Applying options for *
debug2: ssh_connect: needpriv 0
debug1: Connecting to 92.39.xxx.xxx [92.39.xxx.xxx] port 22.
debug1: connect to address 92.39.xxx.xxx port 22: Connection timed out
ssh: connect to host 92.39.xxx.xxx port 22: Connection timed out

On the other hand, if I try to connect through SSH from a machine C to B, there is absolutely no problem at all. So I am sure the port 22 is open.

Moreover there is no public/private key set up beforehand.

Any help will be much appreciated.

Cheers

I found the reason of my problem.

A was banned on B, so I had to unban it with the following command : 

iptables -D fail2ban-SSH -s the.i.p.banned -j DROP
