No Internet browsing with opensuse 11.2 x86-64 XEN

Hi,

I have installed opensuse11.2 on a HP proliant 350
This is a server configuration with DHCP, BIND, XEN and Apache servers

I cannot browse the internet. I looked at same problems described on this forum and did a lot of testing
The network is up : I can ping the router-modem and the DNS address of my provider
I can reach google with the browser when setting the address 209.85.229.103 but not with the name Google

I have disabled the IPV6 flag in the Yast network
I have set ipv6.disable=1 in the boot option
I have removed the file /etc/resolv.conf

Nothing help but I think that it is a problem of DNS. If I stop the BIND server still cannot reach the internet >:(

in the Bind log I see these lines
14-Nov-2009 12:15:55.891 network unreachable resolving ‘www.symantec.com/A/IN’: 2001:503:231d::2:30#53
14-Nov-2009 12:15:56.485 network unreachable resolving ‘za.akadns.org/A/IN’: 2001:500:2f::f#53
14-Nov-2009 12:15:56.485 network unreachable resolving ‘za.akadns.org/AAAA/IN’: 2001:503:ba3e::2:30#53

The addresses are IPV6
Si I think that there is a problem with IPV6

In the /var/log/messages log I have found this
Nov 14 12:00:46 hpprol avahi-daemon[2739]: Leaving mDNS multicast group on interface br0.IPv4 with address 192.168.1.130.

Nov 14 12:15:03 hpprol named[10596]: listening on IPv6 interfaces, port 53

Any idea hoz to solve this?

Use ifup network configuration through YaST, not Knetwork Manager.

I use ifup with Yast
>:(

Never used knetwork manager

DNS seems to be a common problem with fresh 11.2 installations. There’s plenty of other solutions around this forum, most recommending deletion of resolv.conf: switching to ifup worked for me so I haven’t tried any of the others.

I also encountered the same problem and still, I can’t find a better solution. I was able to remove the file resolv.conf but I don’t know excatly what you mean “swith to ifup”.

Problem solved.

removing resolv.conf doesn’t solve the problem because when configuring the network interface with Yast (network settings) the same resolv.conf was recreated.

It contains only the comments and “search xxxxx” where xxxxx is domain search set in Yast ==> Network setting ==> hostname/DNS

the Name server 1 to 3 defined on the same tab in Yast are missing

I added in resolv.conf the strings
nameserver xxx.xxx.xxx.xxxx
nameserver xxx.xxx.xxx.xxxx

where xxx.xxx.xxx.xxx are the DNS address of my provider
Thereafter internet browsing works:)

Manage the network through YaST. There’s a selection box there somewhere to disable Network Manager and use what it calls the “traditional method”. Then just enter your connection details.
This worked for me, but may not work for you.

As far as I can ascertain it is NOT a DNS issue.

I spent 3 days mucking around with settings and YAST configuration but no resolution.

I reset all the default settings via (1) /etc/sysconfig and (2) YAST “Network Settings”. I reinstated IPv6 to active. It is NOT IPv6 in my opinion.

I reverted to firefox 3.0.15 from 3.5 and all my problems disappeared.

I suspect, in my scenario, that it IS firefox 3.5

Cheers and good luck.

I had a similar issue. The Firefox was working okay but after enabling the DNS server Firefox stopped working and neither could I ping. Though $host command did resolve the ip address. Finally if had to manually edit etc/resolv.conf to direct the system towards the name servers.

nameserver (name server ip1)
nameserver (name server ip2)
search domain_name.com

The system is up and running well. YAST has a tendency of overwriting configuration files.

Pam,

I think your errors were related to these:

https://bugzilla.novell.com/show_bug.cgi?id=557385
https://bugzilla.novell.com/show_bug.cgi?id=548678

How to fix for now:

  1. In Firefox, select the menu Edit->Preferences
  2. Select Advanced menu
  3. Select Network tab
  4. Select Settings… for Connections Configure how Firefox connects to the internet
  5. Set to No proxy (Auto proxy… seems to work too)

There is a major bug in OpenSUSE 11.2 X64, that seems to have been around for some months, affecting new installations. It impacts DNS, DHCP, Wget, Firefox, etc., and possibly IPV6 and Avahi, and there are comments all over the discussion boards about various secondary consequences of it, and some proposed fixes, but the correct solution is not prominently noted.

The effect of the bug is that ping to a static IP works, but DNS lookups do not, and thus browsers do not work by URL (but will by IP address), and packages cannot be updated from repositories.

Some have suggested turning IPV6 off, some telling Firefox not to use IPV6, and some to edit /etc/resolv.conf --although this is a temporary solution as the file may get overwritten, or it may prevent future updates by Yast.

vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
THE TEMPORARY FIX IS:

sudo echo “nameserver 8.8.8.8” >> /etc/resolv.conf

WHICH MANUALLY POINTS DNS TO GOOGLE’S NAMESERVER

THEN, FOR THE PERMANENT FIX:

MANUALLY RUN UPDATES TO DOWNLOAD THE PERMANENT FIX FROM THE REPOSITORIES; PARTICULARLY TO DHCPD!!! [Update cites Bugzilla 565030 and 569972]
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

If you are lucky, the fix will be in the update and the bug will go away.
