no, ftp does not. I had no time to dig deep into utmpx world to find the
differences.. 

anyway - I can't see ftp sessions in finger, so definitely there are some
differences:

ftpd is wu-ftpd.

however, I like to see smb sessions in finger...

yes, idle time is bogus - smb/%d is quite hard to bind to some session
specific file.... finger will test file access times to calgulate idle
time.

login & logout times are just ok for me - after pointer dereference fix of
