Changing ssh port - multi server setup

Hi all,

On a multi server setup assuming I will change in ssh config the default 22 port to lets say 5555 will I need afterwards to update anything else in ISPConfig itself?
Any kind of script that is invoking ssh is it checking the ssh config to lookup the default port?

Thanks

 

Thanks Till

 

@till one more question please.
If I disable also the PermitRootLogin in ssh config, would that affect the communication between servers somehow?
If yes, is there a way to setup to ISPConfig to use instead of root lets say the user1 with sudo?
