internet NO, network YES

[filippos]

I've set my network card (Holco Enterprise co. Shuttle 190 Gbit), first thru dhcp and then fixed-ip but no luck.
My system is a SuSE 10.2 GM x86_64.

ifconfig returns OK
route also OK
dig returns OK too
BUT traceroute works partially so we have no internet connection to any site.
I've searched for firewall rules but they don't exist (if they were then, traceroute wouldn't be at step #5 to stop. It would have stopped at step #1).
My other PCs in network work fine.
My router's firewall keeps telling me that there is an attack by this PC on UDP ports 64015-64054 to google UDP ports 33449-33488.

Hm ...

You use an invalid netmask. 192.168. ... is a class C network thus you have to use at least 255.255.0.0 as your netmask. I use at home 255.255.255.0. Then your Bcast IP is 10.255.255.255 which is a BC IP address outside of your network. This should be 192.168.56.255. I don't know whether this fixes your problem - but at least it's a good idea to fix this .

Your eth0 has two IP addresses. Do you actually need them? I'm not familiar with multiple IP addresses for one nic. I would remove this definition if you don't need it.

[filippos]

I think that the problem is the BAAD sis190 module.
If I place another card everything is OK
If there is a newer one than 2006, I would appreciate it.
