ssh - server->target

[bruce]

Hi.

testing priv/pub keys...

working on a local server, behind firewall, with it's own dhcp ip. the
external wan ip is not the same as the internal ip.

create the priv/pub key for the local server
the normal ssh [e-mail] works

change the local eth0 ipaddress...
 rerun the ssh [e-mail] works as expected...

so, changing local eth0/ipaddress doesn't require changing the priv/pub keypair

however, the one thing I haven't tested, is to be able to change the
external ipaddress of either the local/target server..

I'm of the opinion that this wouldn't change the priv/pub key, but I
might be missing something..

thoughts/comments?

thanks

keys have in general nothing to do with the IP

you only have to confirm once again the host-key if you are
connecting from a notebook and the target IP is different

You are correct. It won't be affected.
