Hi everyone,
I'm at my wits end here with this and I don't know who to ask..
For about a week now my OpenBSD router has been acting up in the
strangest ways. Route's dissapear, ethernet speeds crawl to a halt and
other wierdness.. I'm about to wipe this box clean and start from
scratch but I would really like to try and figure out what's going on
first..
I don't know if it helps if I describe some of the symptoms..
I'll try and draw a diagram first if I may...

Interface dc0 is bridged with interfaces dc1&dc2
Firstly, and perhaps most alarming....
When I run the iperf utitlity between the router and a system on the
network I get about 3Mb/s throughput. When I run it between a system on
the DMZ and the router - the same thing. I tried disabling pf and get
the same results.
Running iperf between the boxes on the LAN I get proper results - of
course.
My only ideas are 1) failing NIC
2) NIC Drivers??
3) routing issues?
The second symptom is that periodically my vpn will drop throughout the
day - corresponding with this (I think) whenever I run a continual ping
to somewhere(anywhere) on the internet it will work fine any number of
times but then it'll stop - sit there and hang for 10 seconds perhaps
and then start back up
IF it is a failing NIC - could one bad NIC make the others act up
(interrupts?)
I'm not sure I made myself very clear on this - I'm having a very hard
time tracking this down. Any ideas or suggestions on investigation this
would be appreciated.
Any beautifully simple solutions even more so :)
I REALLY want to figure out what's going on instead of simply wiping the
box clean. Think of all the knowledge value :|
Thanks a lot...
