OpenSSH the secure way to manage your server remotly .

System Administrator are efficent and pragmatic , so why keep a connection alive , if the use idle means that the connection is unused and lock a process for nothing .
This is the reason because the ssh servers disconnect users that are not doing anything for some time .

If you are a PRO and you want to keep a connection alive , and you cannot access the sshd_config file you can add keepalive in your client configuration , how ?

I presume that you use your computer as a personal one , so you can put hands on ssh_config . Modify /etc/ssh/ssh_config and add , or decomment :

ServerAliveInterval 60

This send a keepAlive signal to the server .

There’re others interesting directives in the pre mentioned file :

Host *
Protocol 2

Host : is the directive that point to the remote system , * means any . If you want to specify one just put the hostname
Protocol : make the point on the used version

Host , exclude or include hosts to the directives in the /etc/ssh/ssh_config , for exampe :

Host www.sitonerd.com

will apply keepaliveinterval only in ssh connections to www.sitonerd.com

Host *

will apply directives to all .

Have fun on this 18th of August
