Re: kernel 2.6.6



I can suggest to check some simple things.. what is the output
of /sbin/ifconfig and /sbin/route (you don't have to be root to get this)
when the network is not working properly?


As root, does tcpdump show any traffic if you run it on your machine and ping
your machine from another?

Ok Thanks. Here is the output ifconfig and route.




$ ./ifconfig
lo        Link encap:Local Loopback
         inet addr:127.0.0.1  Mask:255.0.0.0
         inet6 addr: ::1/128 Scope:Host

         TX packets:4018 errors:0 dropped:0 overruns:0 carrier:0
         collisions:0 txqueuelen:0
         RX bytes:5138658 (4.9 Mb)  TX bytes:5138658 (4.9 Mb)


$ ./route

And I could not ping but I try to activate the nic through network-configuration and here is what I got.

$ ./tcpdump

I'm not sure what all this means(well other than it's not working) but if someone has ideas I would appreciate it.


Thanks Law
