ping ok, can't do anything else

Hi Folks,
         I'm trying to install on an asus R2HV and have a weird problem with eth0 that's stopping progress beyond the packages on the CD:

Windows networking / web browsing works fine on the same box so confidence in the hardware is high.

Eth0 is DHCP client, module (auto loaded) is r8169.

Internet connection is cable broadband via a NAT box, local network is 10.24.2.0/24

Kernel version 2.6.22-ARCH

I can ping external addresses OK, 'ping 4.2.2.2' works fine.

I can resolve names OK, 'ping www.bbc.co.uk' works fine.

However any attempt to use wget or pacman results in a connection timeout after a minute or two, any ideas how to proceed here? I'm stuck!

Many thanks,
               Robin.

Re: ping ok, can't do anything else

What do these show:

route -n
iptables -L -n

Re: ping ok, can't do anything else

Hi brebs,
     route -n shows:

   

Destination         Gateway          Genmask                Flags        Metric        Ref      Use      Iface
10.26.2.0            0.0.0.0            255.255.255.0         U              0                0         0        eth0
0.0.0.0.              10.26.2.1         0.0.0.0                   UG            0                0         0        eth0

(excuse the rough transcription, can't cut n paste for obvious reasons   )

Which looks good to me, 10.26.2.1 is indeed my NAT box private side IP address, I don't know the meaning of those flags though.

iptables -L -n shows:

Chain INPUT (policy ACCEPT)
target          prot   opt source             destination


Chain FORWARD  (policy ACCEPT) 
target          prot   opt source             destination


Chain OUTPUT     (policy ACCEPT)     
target          prot   opt source             destination

which, I think, means that there's no firewall issue here ...

Hope this helps,
                   Robin.

Worth a try:

echo "0" > /proc/sys/net/ipv4/tcp_window_scaling

Thanks for the idea but nope... no change, if I run ifconfig on another VT while wget is attempting to fetch a file I can see packets being sent and received with zero errors, overruns, dropped etc.

I'm just burning an ubuntu live CD to see if that works on this hardware, might provide some insight

Cheers,
        Robin.

Re: ping ok, can't do anything else

Hmmm.... same behaviour in ubuntu, 2.6.22-14-generic kernel, r8169 module auto loaded again.

I guess it's time to get wireshark or something installed for more detailed info.... tomorrow, late here, time for bed.

cheers,
        Robin.
