[PLUG] Odd name resolution issue on Ubuntu 9.10
|
I'm having a weird name resolution problem with an old laptop I
installed Ubuntu 9.10 on. I use DHCP from my LinkSys router, pointing to
an Active Directory server for DNS. This works fine for my Windows
laptop, and another Linux laptop. But observe this:
$ ping dim-win2300
PING dim-win2300.DaCrib.local (10.0.0.60) 56(84) bytes of data.
64 bytes from dim-win2300.dacrib.local (10.0.0.60): icmp_seq=1 ttl=128
time=0.590 ms
$ ping dim-win2300.dacrib.local
ping: unknown host dim-win2300.dacrib.local
turgon@turgon-laptop:/$ nslookup dim-win2300
Server: 10.0.0.60
Address: 10.0.0.60#53
Name: dim-win2300.DaCrib.local
Address: 10.0.0.60
turgon@turgon-laptop:/$ nslookup dim-win2300.dacrib.local
Server: 10.0.0.60
Address: 10.0.0.60#53
Name: dim-win2300.dacrib.local
Address: 10.0.0.60
So I'm at a bit of a loss as to why pinging the short name works, but
not pinging the FQDN. Especially as a lookup works for either short name
or FQDN.
$ more /etc/resolv.conf
# Generated by NetworkManager
domain DaCrib.local
search DaCrib.local
nameserver 10.0.0.60
I have no entires in hosts (except for 127.0.0.1, of course)
$ more /etc/nsswitch.conf
# /etc/nsswitch.conf
#
# Example configuration of GNU Name Service Switch functionality.
# If you have the `glibc-doc-reference' and `info' packages installed, try:
# `info libc "Name Service Switch"' for information about this file.

clues? Pointers? etc ...
