suse 11.1 extremely slow beyond my router?

English Network/Internet
1

This has been a fun excercise, lol.

It started out with me upgrading my mobo to a Gigabyte GA-X48-DS4.

Obviously, Windows bailed when faced with the new devices, so I had no choice after 3 reboots of it’s lengthy time consuming self diagnostic/repair tools, to just reinstall.

Then came the fact that Windows did not like the new NICs but of course there was a set of drivers included in the mobo’s box so no real problems there. You can see where this is going right^^

Hooray for shell & mkinitrd. With a quick boot in to the SUSE 10.3 rescue shell, I mounted the drives and ran mkinitrd. Job done, the system instantly booted with the new mobo.

However, SUSE 10.3 did not like the new nics either and no matter what I could do, it just was not gonna work. So, as I was planning on upgrading to 11.1 anyway, I did and it took less than half the time the similar Vista reinstall took. Not bad considering I was upgrading from 32 bit SUSE 10.3 to 64 bit SUSE 11.1 :wink:

So here’s where it starts to get frustrating. The nics in question are the dreaded Realtek 8169 chips that apparently are actually 8168B/8111B chips.

SUSE 10.3 saw the nics and let me supply configuration data but refused to accept that they were actually wired >:(

SUSE 11.1 sees the nics, lets me supply configuration data and accepts that they are wired.

I can even access my router’s admin page via a browser over the lan. Using the router’s admin tools, I can see the Internet connection is working because I can resolve addresses and ping them.

Yet I cannot access anything beyond my router from the SUSE system, regardless of whether I am using the shell or gnome, or whether I use dns or ip addresses. Well sort of :\

For one thing, the dns resolver is definitely not working. I cannot resolve addreses in any gui or cli application.

If I resolve the name of say BBC - Homepage using the router’s admin tools and then access the website via the ip address in firefox, I actualy get the page after a time span that can only be measured accurately in eons rotfl!

I cannot ping nor traceroute the dns servers which are 2 hops beyond my router.

I checked the nic settings using ethtool and it all looks good, which is a relief considering all the posts I read said that the nic would suffer the same problems it did in SUSE 10.3.

So to recap, I can access my routers admin interface using Firefox over the lan. The routers internal admin dns resolver and ping tools work perfectly. A laptop on the same lan, using the same router at the same time, gets instant Internet responses. Of course when the same computer is booted in to Vista it gets perfect Internet access using exactly the same nics, router and cable.

My system is

O/S: openSUSE 11.1 64bit (no updates/patches)
MOBO: GA-X48-DS4
CPU: Q6600 @ 3.2Ghz
RAM: 4GB PC2-1066

The nics are onboard and are reported as RTR8168B/8111B in the boot log but are loaded with the r8619 module, which is used by the MII module according to lsmod output.

ethtool confirms the nics advertise auto negotiation and are running 100Mb/s full duplex on MII port, current message level 51 (decimal).

Now ordinarily I would suspect that if I could solve why I cannot ping beyond the router, then the dns resolver problem would be solved.

However, I am confused by the fact that I could load BBC - Homepage by ip address in Firefox, albeit excrutiatingly slowly.

So any ideas anyone?

  1. If you have not done so already disable IPv6 globally with YaST and in
    Firefox. If this solves your problem just quit. With some ISPs IPv6 causes
    problems.
    2 Assuming the above does not help, can you post the results of the following
    commands:

/sbin/ifconfig -a
/sbin/route -n
cat /etc/resolv.conf

If you are using dhcp, it is possible that your router is not setting the DNS
server. In this case set a static DNS with your ISP’s DNS server’s IP.
(Their DNS server’s address should be available on their web site)

Okay I was asked to make sure ipv6 was disabled and provide the following information

/sbin/ifconfig -a
/sbin/route -n
cat /etc/resolv.conf

So ipv6 was disabled, it’s one of the first things I check with networking on any o/s tbh.

Here’s the ouptut requested, plus lsmod output, ethtool output and an extract of perhaps relevant entries in my dmesg

resolv.conf output

/etc/resolv.conf file autogenerated by netconfig!

Before you change this file manually, consider to define the

static DNS configuration using the following variables in the

/etc/sysconfig/network/config file:

NETCONFIG_DNS_STATIC_SEARCHLIST

NETCONFIG_DNS_STATIC_SERVERS

NETCONFIG_DNS_FORWARDER

or disable DNS configuration updates via netconfig by setting:

NETCONFIG_DNS_POLICY=’’

See also the netconfig(8) manual page and other documentation.

Note: Manual change of this file disables netconfig too, but

may get lost when this file contains comments or empty lines

only, the netconfig settings are same with settings in this

file and in case of a “netconfig update -f” call.

So far, no matter what I have tried does not work and ofc all other computers on the network are fine, lol

Sadly I will be moving away from SUSE to Mandriva again, same thing I tend to do every 12 months lol.

Unfortunately I cannot get 11.1 network to work.

I replaced the mobo nics with a pci nic to see if it was the drivers or the network sub-system that was faulty. It seems that it is the network system that is at fault.

I have checked everything I can to the best of my abilities and I simply cannot get 11.1 networking to work, so as I have to use my computer for work I have no choice but to move on to another distro that works for me. After checking google for people with similar problems and finding none, I have to accept that this problem is local to me for some weird reason, I even reinstalled 11.1 from scratch because I did not trust the upgrade that I did.

Then I booted with a Mandriva live cd and it worked straight away with full networking.

I tend to switch to Mandriva when SUSE does not work for me and wait for the problem to be solved through patches before I come back again. So I will not be removing it from my system, just putting it into hibernation for a while.

Fingers crossed the networking issue will be resolved soon.

Well this sounds to me like a configuration issue rather than a hardware/driver issue.

One thing that looks a bit odd to me is your list of nameservers (DNS).
nameserver 192.168.4.100
nameserver 192.168.8.100

These are local addresses on different subnets to your Suse box. I presume that one of these IPs belongs to your router or some other box handling DNS queries? Which is a bit odd as I would expect it to be on the same subnet as your Suse box (192.168.0)
If there is no route to these hosts, then that is likely why you cannot browse the web from your Suse box. Have you tried pinging them from your Suse box?

What I tend to do is use the DNS server my ISP gives me as the DNS server in Suse, ie using them in Suses network config. I find that if I put the actual IP address of my ISPs DNS servers in there, DNS lookups are much quicker than going via my router. Its worth a shot, but of course YMMV.

Hey Grans, thanks a lot for pointing out the embarrassingly obvious, that I had put the wrong dns addresses in resolv,conf :X

I will swear though that the first time around, i.e. when I upgraded from 10.3, the resolv.conf file would have had the correct addresses in it because the upgrade process does not change your existing config.

In any event, I had changed it to be the address of my router, i.e. namesever 192.168.0.1 but that did not work either.

Now I can set my resolv.conf to use either my router address or the isp dns addresses which are actually 194.168.4.100 and 194.168.8.100, with complete success either way. So it looks like that last complete install on to a freshly formatted partition fixed things, even though I had done that before.

cough note the subtle difference in the actual isp dns addresses and the ones I had entered rotfl!

Now I have a dilemma in that for the first time in a very long period, I have both SUSE and Mandriva working installations on my system.

Oh well it will be interesting to compare both distros. Already I can say that they both incorrectly state the speed of my Q6600 as 3.6Ghz when it is in fact 3.2Ghz.

I will need to resolve this dilemma soon though, as one of them will need to make way for Windows 7 RC.

Hey Grans, thanks for the reply which made me look at the SUSE distro again, otherwise I might not have looked for acouple of weeks. Guess it was a case of “can’t see the wood for the trees” in the end.

PPS: On a good ending, I can say that the r8169 driver is definitely working correctly in the latest kernels.
