Connect to Internet via a router

Hazzie · 10-23-2004, 06:34 AM

Hi i am getting the following message when i try to connect to the internet (or even ping an IP address).

ping 212.28.224.56
connect: Network is unreachable

I can ping from my Linux box to my XP box on my internal network fine.
I can ping my router fine.
My XP box can connect to the internet (its how i am writting this post).

From a few searches people have asked for this information

route -n

Code:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.0.0     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     0      0        0 eth0

and ifconfig

Code:

eth0      Link encap:Ethernet  HWaddr 00:0C:6E:2F:8B:44
          inet addr:192.168.0.3  Bcast:192.168.0.255  Mask:255.255.255.0

          RX bytes:54630 (53.3 Kb)  TX bytes:52352 (51.1 Kb)

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:16436  Metric:1

          collisions:0 txqueuelen:0
          RX bytes:700 (700.0 b)  TX bytes:700 (700.0 b)

my router is configured as 192.168.0.1

From the above route table i presume it says that my network card (eth0) can access the following paths 192.168.0.0 and 169.254.0.0. I have no real idea how the 169.254.0.0 got in there (but thats not the issue here i think). Do i have to specify a specific IP for the router in that table and if so is the command to do it

route add -net 192.168.0.1 netmask 255.255.255.0 dev eth0

Am i on the right track?

You need to specify a gateway:

route add default gw 192.168.0.1

Also make sure that your /etc/resolv.conf file contains nameserver
information.

Ahh well i was in the right area then..

Thanks for your quick reply, it worked a treat.

Just a follow up to this. I shutdown my machine last night. When i switched it back on the route that I added last night no longer appears in the routing table and i cannot access the internet again. Is there a way to make it stick?

Hi,

I think you need to add this line in /etc/sysconfig/network

gateway=192.168.0.1

and save the file

then restart the service ..and it will stick eventhough you boot the system
