ok it's my fault. The man page is too old in fact the command should be
jerry at backup:~ $ sudo route add -net 192.168.1.0 netmask  255.255.255.0
maybe you must replace -net by -host but i think not.
Can you post the output of netstat -r but this time on the other machine.
The machine form wich you can do ssh.

to log into the other machine sshd must run on the machine 192.168.1.50
main.jerrysdomain.com main. So the the command 
jerry at main:~ $ sudo /etc/init.d/ssh restart
but this time on the other machine (main.jerrysdomain.com)

if there is no firewall on the other machine yes. Try
jerry at main:~ $ sudo iptables -L
but also on the other machine (main.****)

Depends on wich file you touched. restart networking alos just to be sure.
