Hi all,
I was just asked by the "system administrator" at the school where I work to take
down my Linux box and I'm looking for vindication:
I put the words "system administrator" in quotes because the man unfortunately isn't
even given the authority to create NT trust accounts for our NT domain- anything that
involves real sysadmin is run centrally (and, of course, incompetently) by the school
district. We've been having all sorts of network problems at our location, and after
months of troubleshooting someone noticed a non-Windows, non-school-supplied machine
running on the network, which allegedly violates some rules (it would be pointless to
bring up that there is no money for me to be given a computer, so if I want one at
school I have to bring it in myself). What I wonder, though, is if there is some
possibility that the computer is responsible for the network problems, which was just
described to me as 'something creating so much network traffic as to bring the network
down.' First, the machine had been running Samba. The smbd settings relating to the
machine acting as a Primary Domain Controller were all set to either Auto or No. I
did notice, though, that one time that the network went down the nmbd process was
using up a lot of processor time. Is it possible that the machine was forcing domain
controller elections and thus overloading the network? Second, I've been using ssh to
log in to my machine at home, (using an X client only on extremely rare occasions).
As I understand it, ssh does not generate a huge amount of data, it simply requires
processing power on either end and should not affect the network. Third, if there
were a situation where password security on my machine were compromised, could it be a
more dangerous tool for mischief than the Windows machines? It hasn't been running
any telnet or ssh daemons, although it has been running the exim MTA. Obviously, on a
well-run network this would not be an issue, but this is sort of situation where
anything that is unfamiliar is automatically suspected.
