Hi all,

I have a server that is used by a number of people.

Each person has their own user id, but there are a number of IDs that
all people can use.

They access the server via SSH using public/private key authentication.

Is there a way to determine, from the shell, which public/private key
was used to authenticate the user?

Thanks,

OK, the method I was going to use to find out the logged on users's IP
address was to use "who -m" and "host" to determine it. (This is a Red
Hat box)

Unfortunately, this falls over if the user uses ssh to simply submit a
command.
"who -m" in this instance returns nothing.

So, can anyone advise on how to determine the current user's IP
address?

Thanks,

Dan Rumney

> netstat -tnp

Thanks,

That lists all the current connections, but this user id doesn't have
root privelige, so the PIDs aren't shown.

Right know, I can't think how I could take that and determine the IP
address that the current user is connecting from.

Any suggestion are welcome... i'm still searching the net and
scratching my head

c.o.l.security pointed out that $SSH_CLIENT is set with the client's IP
address

Thanks all,
