I have a config file in my .ssh dir that looks like this

Host somehostA
HostName 123.45.67.89
User katsh

So from my local machine, i can ssh into multiple machines by their name in the config file, like so

ssh somehostA
ssh somehostB
ssh somehostC
...
etc

Is it possible to get a list of all machines i am connected to, by their name?

I know I can do:

 lsof -i tcp -n | grep '\<ssh\>'

and i'll get something like

ssh        9871 katsh    3u  IPv4 400199      0t0  TCP 987.654.2.2:47329->987.654.2.2:47329:ssh (ESTABLISHED)
ssh       20554 katsh    3u  IPv4 443965      0t0  TCP 123.456.7.8:41923->123.456.7.8:ssh (ESTABLISHED)

But it does not list their names, just IP
