RE: Network Config Problems

[root linux1 root]# ifconfig eth0 195.224.13.86 broadcast 195.224.13.255 gw
195.224.13.1 netmask 255.255.255.0 arp up
gw: Host name lookup failure
ifconfig: `--help' gives usage information.

if you like you can specify it, it might help:
ifconfig eth0 195.224.13.86 broadcast 195.224.13.255 gw 195.224.13.1 netmask
255.255.255.0 arp up

Why is the mac not showing? are you just showing 00 for the purposes of the
mail?
What happened with the tracroute?

Yes, just did that and then:

ernel IP routing table
Destination     Gateway       Genmask         Flags   MSS Window  irt Itace
195.224.13.0    0.0.0.0       255.255.255.0   U         0 0          0 eth0

There is no firewall on the outter network,

195.229.13.0 doesn't exsist.. should that top table look like this:

195.224.13.86    195.224.13.1      255.255.255.0   U     0 0      0 eth0

?

Thanks for all the help so far :)

,Tom

did you try "ifdown eth0" first?
what was "ifconfig -a" after that?
what was the routing table after that "netstat -rn"?


When you bring up the network interface try using a MTU of 1300, I have seen
where there is an issue with certain firewalls.
also try doing a traceroute:

"traceroute www.yahoo.com"

This should tell you where you are getting hung.

That seem to work, I tried pinging again, and it seems to detect the ip of
the destination.. i.e. if I ping ns1.iapbb.net

ping ns0.iapbb.net
PING ns0.iapbb.net (216.127.80.104) 56(84) bytes of data.


216.127.80.104 being the ip of the nameserver.. so its somehow getting out
to the www?

>>Try to configure all again:

ifconfig eth0 195.224.13.86 broadcast 195.224.13.255
netmask 255.255.255.0 up

and then, restart your eth0:
/etc/rc.d/init.d/network restart
