I tried finger as the other commenter suggested. I tried bunch of variations. Whole username, 8 chars truncated, and a shorter version which was in my notes. I also tried both sdf.org and freeshell.org. All of them gave me an empty output. I guess the fact that it didn't output no such user
means it must be either of them. Or all of them refer to the same user.
I also found an email sent from my sdf user. The address in format username@sdf.org
had the whole username (more than 8 chars). Then there's the shortest version of the name in my notes. That's written as sdf.lonestar.org/1/users/username
. No idea what that refers to. Seems I didn't take very good notes. So which of these would more probably be the correct one?
I actually tried to finger the same usernames on sdfeu.org and it reports
no such user
so I guess it's not there.
