[ubuntu] Local lan DNS suffix resolution problem

http://ubuntuforums.org – Hi All, I have been plagued by an annoying DNS issue for a long time and was wondering if anyone has any solutions. Our corporate LAN has a DHCP server which assigns my PC's IPs as well as a domain suffix details. My resolv.conf ends up like this: # Generated by NetworkManager domain aa.domain.local search aa.domain.local nameserver 10.0.0.1 nameserver 10.0.0.2 Problem is as such. When connecting to lan servers I can successfully connect using just the hostname, eg: exchange ping exchange PING (HowTos)

Hello, I'm experiencing a weird DNS issues.

This is a bit of a weird one. I'm running ubuntu on a Windows domain. If I type "ping server" I can ping correctly and I can connect without any problems. It looks up my search domain (domain.local) and everything is hunky dory.

Problem is when I try to ping server.domain.local.

I just got FIOS, MI242WR router hooked to my desktop using DHCP over ethernet.

a `ping google.com` succeeds, but it takes ~10 seconds for each ping to succeed.

If I ping the google IP, the ping runs every second, as I would expect.

Here is my resolv.conf:

Code: me@me:~$ cat /etc/resolv.conf # Generated by NetworkManager

DNS Settings 3 years 25 weeks ago

I am trying to troubleshoot a DNS issue. I added a bogus nameserver as the primary in resolv.conf and a legitimate on as the secondary. I modified the timeout to 0 seconds so it finds the 2nd DNS server more quickly. However, when I try to ping another server, it still waits about 2 seconds then finally gets a response. I do the same test with a Windows server and the ping response is immediate.

My /etc/resolv.conf shows:

# Generated by NetworkManager domain someuniversity.ac.uk search someuniversity.ac.uk nameserver 128.85.161.265 nameserver 128.85.161.241

I understand nameserver but what is the usefulness and relevance of "domain" and "search"?

Thanks .

My problem is as follows.

I have two internal dns servers set up and all my servers have both of them in the resolv.conf Our main dns server went down and suddenly no server could see each other. I edited a few of the servers resolv.conf manually and committed out the first (down) dns server and that machine would instantly be able to ping again.

Hi,

I am using Ubuntu 9.04 (x86-64).

My internet connection is not working, i've tried to fix it and the issue seems to be with DNS. I can ping google's IP, but i can ping it URL.

I have used the GUI network manager(from Gnome's equivalent of the Windows system tray), to add the DNS IP addresses to the IPv4 wired connection - that hasn't helped.
