If you need to log back in to a dialup that you were logged in to
earlier (to recover a file from /tmp for instance), but don't remember
the name of the dialup you were logged in to, you can check the
file ".lastdialup" in your home directory to see which dialups you
have been logged in to most recently.

The ".lastdialup" file lists up to five dialups that you have been
logged in to. If you have not logged in to another dialup since the
one you are looking for, it will be the one listed on the last line of
the file. If you had to log in to a dialup again to be able to check
your .lastdialup file, then the dialup you are currently logged in on
will be on the last line, and the earlier dialup will be on the
second-to-last line.

Note that this is dependent on having standard dotfiles; if you've
modified your login files extensively, then you may not see this
behavior.
