I recently upgraded to FreeBSD 9.1-STABLE, and there was a strange added side effect. Users that telnet into the machine seem to have their logins forever ghosted in who/w. If a user connects via telnet, then logs out, their login still remains in the w/who. If another user logins in with the pty they had, whatever they do also shows up in the ghosted w/who of the previous user using that pty. For example: User X logs in, runs BitchX. Detaches the process and logs out.User Y logs in, gets assigned User X's previous pty, who/w now reports that user is running BitchX. That user has no access to the BitchX session or anything, it's just being displayed weird in who/w. I seem to remember this problem like a decade ago and I had written a script or there was a script that passed around called clearlogin. Any ideas?

Thanks all!Damon Is GNU screen involved? It sounds like it.
