This is really weird.
My laptop sent out a DNS query to my primary DNS server at WORK!
After 5 seconds, it sent another query to the secondary DNS server
at WORK!
It looks like this.
0.0 laptop -> workdns1 query laptop.workdomain.com
5.0 laptop -> workdns2 query laptop.workdomain.com
5.1 workdns2 -> laptop no such name "laptop.workdomain.com"
5.1 laptop -> workdns1 query laptop
10.1 laptop -> workdns2 query laptop
10.2 workdns2 -> laptop no such name "laptop"
10.3 laptop -> workdns1 query laptop
15.3 laptop -> workdns2 query laptop
15.4 workdns2 -> laptop no such name "laptop"
Just to throw a little confusion in, "workdns2" is our DSL modem.
At home, I have a similar DSL modem with the same IP = 192.168.1.254.
So by pure chance, the DNS queries I send to "workdns2" happen to
be answered by my DSL modem at home. But this does not change the
overall problem.
If I "ping laptop", I see a normal DNS exchange happen.
0.0 laptop -> homedns1 query laptop
0.1 homedns1 -> laptop laptop = 192.168.1.100
Just to be sure, I checked my /etc/resolv.conf file. It looks like
this:
search homedomain.com
nameserver 192.168.1.1
But when I start an X-windows application, it does not use my updated
DNS information... instead, it insists on using old DNS information
from work to look up my local hostname.
I tried adding "192.168.1.100 laptop.homedomain.com" to my hosts
file, but that did not help either.
