openSSH default user ...

[Damien Touraine]

Hello,

I connect from my computer to several systems with one specific user 
login on each system. By default, openSSH use the current login name as 
default name to the remote host. As each login may have been generated 
randomly, I would like to don't have to specify the login for each computer.

So Is there any way to include a configuration file that gives for each 
remote host, the default login name to use ?
