can get the list of my entire roster but not the status of a particular buddy.

Maybe that buddy is not in your roster?

what am i doing wrong here ? $user is undef !!

It appears you're not reading the fine manual (Net::XMPP::Roster), online returns undef when a user is not online

Try Dumper-ing the results of query  my %hash = $Roster->query('bob@jabber.org');
