My apology, that was a typo. I have tried several times for different
global ip address every time I reactivated the connection. So,  Ssh
was done to the right IP but failed. I baceme curious because with the
same provider and the same service, I was able to do ssh before. Also,
inside  LAN with ip 192.168.xx.xx, ssh works fine. /etc/init.d/sshd is
running.

The customer service said that  ssh is not allowed. So, what to do
then? I badly need a server with global IP for experimenting grid
computing.
