Peoria, IL). He also got a new computer, so I'm trying to help him
set up his old PC as an OpenBSD 3.1 firewall/gateway.
I'm having some strange problems with his network configuration that I
can't seem to figure out. I instructed OpenBSD to use DHCP on the
ethernet card that is connected to the cablemodem.
On boot, I get an IP address assigned, but it's not the same one that
his Windows box gets assigned. In fact, it's not even close. When
OpenBSD boots, it gets an IP address of 10.14.something.something,
while the Windows box would get 12.something.something.something. In
fact, my friend also had one of those hardware routers, which likewise
got an IP address of 12.x.x.x.
Now the strange thing is that with this (apparently bogus) IP address,
whenever I do an nslookup on any symbolic hostname, it always returns
12.x.x.x as the IP address. But at the same time it appends some junk
domain information to the hostname that I queried. I'm not at his
computer now, but here's a forged example of what nslookup would
return if I were at his box:
Server: dns-something.something.insightbb.comQuote:> nslookup mtco.com
Address: (whatever the IP is of insightbb.com's DNS server)
Now if I were to do a dnslookup on an actual numerical IP address, I
get a "Non-existent host/domain".
So clearly there is something messed up with the hostname/dns
configuration, but I'm not sure what that is.
I read a thread a while back about OBSD possibly needing the TTL fix
in dhclient (upping it from 16 to 128). I applied this patch to the
dhcp package, and installed it, and it didn't have any effect.
I also tried turning the cablemodem off for about 10 minutes, then
cablemodem, I had a permanent symbolic hostname (something like
c123456-a.x.x.home.com), but a dynamic IP. So when OBSD invoked DHCP,
computer doesn't have anything like this, so I'm not sure if there's
something special I need to have dhclient send to the DHCP server.
Anyone got any thoughts on this? Any ideas?
