how do we specify an ssh default identity?
In your ~/.ssh/config file put:
IdentityFile /home/myuser/.ssh/keyhello
which will tell the outgoing ssh connections to use that as the default identity
You can specify an alternate keyfile on the command line with the -i
option, or you can change it permanently with IdentityFile
in the ssh client config file.
/usr/bin/ssh-copy-id will use the last created file that match id_*.pub. To change which one is default just touch it.
me@my-machine:~/.ssh$ touch id_rsa id_rsa.pub
