Hi, I have a weird problem I cant solve. I have several computers, two with xubuntu 9.10 One of them, acting as a media server, has stopped to work when it comes to external network.. I can do for example: ping google.com

Which gives me an ip adress back, like:

name@Media:/etc$ ping google.com
PING google.com (66.102.9.147) 56(84) bytes of data.

That tells me it reaches the dns?, but I get no response at all... If I ping a local computer all works fine. I can also reach the computer via ssh without any problems. I have always used network manager, but now I uninstalled it and made the settings manually like this:

/etc/network/interfaces

auto lo
iface lo inet loopback

auto eth0

iface eth0 inet static
address 192.168.1.52
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1

Still no luck. I have no specific settings for this one in my router, and all the other computers, including my win laptop works fine. This is very annoying since I cant even do an update or anything..

ifconfig looks like this:

  eth0      Link encap:Ethernet  HWaddr 00:24:1d:9f:10:89
          inet addr:192.168.1.52  Bcast:192.168.1.255  Mask:255.255.255.0

route -n like this

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.1.0     0.0.0.0         255.255.255.0   U     0      0        0 eth0
169.254.0.0     0.0.0.0         255.255.0.0     U     1000   0        0 eth0
0.0.0.0         192.168.1.1     0.0.0.0         UG    100    0        0 eth0

I do not know where the adress starting with 169.254 comes from.. Could that be a part of the problem?

Hoping for some assistance since Im totally stuck here.. /george
