Tim,
I think a better way would be 'ps ax | grep login'. 'ps aux' will
list even processes not attached to a terminal (which will not be the case
for a login shell).
I dont have two machines at home (I do at the office, but I am
answering this from home), which is why I cant assure you that this will
work for telnet logins from remote machines. I shall try this in the
office tomorrow...
Another thing that has been ignored by the posters on this topic
has been the question of how to prevent the guy from relogging on. If all
users (and not just a specific user) are to be kept out, then simply
create a file /etc/nologin ('touch /etc/nologin'). Otherwise, one has to
setup an appropriate entry in /etc/usertty corresponding to the user. The
man page for 'login' explains in detail how to go about this.

There is no such thing as luck. 'Luck' is nothing but an absence of bad luck.
