on Friday i set up 4 old celeron boxes as DNS servers for a client. after
about 5 minutes, their ability to reach the network vanishes... they can't
ping their router, and inbound network traffic vanishes. rebooting fixes
the problem... for another ~ 5 min.
the only things running are chrooted bind, postfix, and webmin. ipfw is
on, with firewall_type="open". i've also tried it with ipfw disabled.
The same thing happens with my laptop, which is also running 5-STABLE as
of about noon on friday.
I know this sounds like a network issue, but is there anything in the
system that might cause thist type of behavior? it doesn't seem to be the
hardware - my laptop is a pentium M centrino system with a bg nic, and
they're old Celeron 500 machines with fxp nics.
I believe something happenend out there in DNS land around noon on
Friday...on the root servers possibly? I've been struggling with slow
SSH and SSL connections that started around that time, and when I've
posted, others have reported similar things...all starting around noon
on Friday. AFAIK, something happened that affected reverse DNS
lookups...on the machines on which I was able, I could fix SSH by
setting "UseDNS no" in sshd_config. Today, I cured all the slowness (I
think so far) by adding in-addr.arpa zones for my internal 10.x.x.x
subnets.
