My Linux laptop can no longer resolve DNS
I moved my Linux laptop from my home network, where everything seemed to be working fine, to another wireless network. All of a sudden, it no longer seems to be able to resolve dns (at least Firefox/Thunderbird).
My Firefox/Thunderbird in my Windows virtual machine works fine, and in Linux all other Internet things seem to be working fine (such as Skype, and pinging google.com etc). I can even enter an IP address directly into Firefox and it will work, just typing an actual domain name such as www.google.com won't work and give the standard 'cannot find server at ....' error. What could have gone wrong here? (Reinstalling Firefox/Thunderbird to latest versions, and starting them in safe mode changed nothing.) The only thing I can think of is looking at 'route' command output, which shows: Code:
Destination Gateway Genmask Flags Metric Ref Use Iface Any other changes to dns settings I may need to make? Not sure why things would have just stopped working when I changed the wireless network to which my Linux laptop is connected. But everything else seems to be working fine, except for DNS resolution in Firefox/Thunderbird. If you could please help, I'd really appreciate it! |
This is not a problem with your routing table. Most likely the DNS addresses in /etc/resolv.conf are incorrect or non-existent.
If you are using DHCP on the new network verify that the DHCP server is supplying the correct DNS addresses. If you have a static address assigned on your new network find out what the correct DNS addresses are and update your /etc/resolv.conf manually. |
Since the problem is only in firefox, and you can ping google.com, DNS is working.
Can you browse using another browser? Try to disable ipv6 in firefox. http://thedaneshproject.com/posts/di...-in-firefox-3/ Kind regards |
Thank you very much, marking thread as solved. People who stumble upon this thread can solve this problem by disabling ipv6 as described above in both Firefox and Thunderbird (must do it in both to get both working). Thanks again!
