Dear Alepha One, I'm on an internal university email list for bugtraq. Can you pass this onto the list, as it seems my emails to bugtraq usually get dropped? Thanks, Gary ------------------cut here----------------------------------------- And what about the default of the ports 256, 257, 258 and 259 appearing on every interface? A little concerning, since they are not listed in the table of ports in the main manual. Even more concerning when I'm told they are for secure remote support, logging and configuration control! This obscurity makes one rather nervous. Cheers, Gary On Tue, 27 Oct 1998, David S.
