DNS problems...
our main server and DNS is bushwack.gilo.jlm.k12.il here at the school,
and we added a few CNAME lines in the named DB so we can address it as
www, mail, ftp etc.
at some point, Oori also added gilo.jlm.k12.il with the same IP address,
and an MX record routing the mail to mail.gilo.jlm.k12.il, which is again
the same computer as appears in a CNAME line.
problem is this: for the last 24 hours, aqpperently noone from outside
our net can see the 'domain-only' alias, which means ira@gilo.jlm.k12.il
is not recieved. Not the MX nor the A records work, on the other hand,
the rest of the aliases we have for bushwack DO work!
I tryed kill -1 on named, but the problem stayed! in the end I discovered
that only kill -9 and firing up named again can work. But this incident
still haunts me... why didn't only ONE of the aliases work?
is Hank playing tricks on me, or is this some internal bug?!?
