Run

This will tell you the last place that packets arrived at.

Here is a sample of a traceroute from one of my Linux boxes toward www.google.com:

You can see replies from

192.168.1.1 (my router)
10.0.0.2 (lan side of my DSL modem)
xx.xxx.xxx.1 (my ISP's gateway)
204.252.74.6 (a router at my ISP)

If you don't get a reply from a given router, you'll see a line that looks like


Since you have a non-routable IP address, (192.168.xxx.xxx), I'm assuming that you have a router. If you can log in to your router, you can generally run a ping and a traceroute from the router toward your ISP. You may very possibly have to call your ISP.

Post output for "route -n" from root console, please

if i ping or traceroute any address it gives : connect: Le réseau n'est pas accessible. anyhelp , when i had only one network card everything were fine

please help me with this, it seems that cards desactivated when trying other addresses

My French is not so good, but I'm guessing that this is a routing problem. I would follow nimnull's advice:

this is result of route -n,

Destination Passerelle Genmask Indic Metric Ref Use Iface
82.151.83.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
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 0 0 0 eth1

i can ping anything in "82.151.83.XX" or "192.168.1.xx" it gives result, but trying to ping any other address , it shows

le réseau n'est pas accessible which is "the network is not accessible"

thanks

That is absolutely right behaviour.

Tell please your network configuration: GW and where does it connect to, eth0 or 1?

i changed my gw in /etc/sysconfig/network adding GATEWAY=82.151.83.1 but it didnt work
what shoudl be done
thnx

OK!

I will ask different way.

What OTHER addresses do you want to ping?

ping 62.159.55.3 for example , i tried to add gate way using /etc/sysconfig/network adding line GATEWAY=82.151.x.x
i did this command #route add default gw 82.151.73.x eth1 ,
it gives SIOCADDRT : aucun processus de ce type
nothing chnged

But your computer does not know anything about 62.x.x.x network.
And GW can be only ONE, you can't use many.

What was a command for adding a new route?

May be you were trying to add GATEWAY=82.151.83.1, but here nothing says about it:
Destination Passerelle Genmask Indic Metric Ref Use Iface
82.151.83.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
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 0 0 0 eth1

Ok, there are a couple of things going on here:

1. you don't have a default route set up, meaning that your computer doesn't know where to send any packets which should be headed toward the internet.
2. The route toward 169.254.0.0 indicates that you probably have a link local IP address set up on eth1. This probably isn't what you want.

So: Which interface are you expecting to get internet through? eth0 or eth1? How is your network set up? Do you have a router? What type of internet connection do you have?

I also want to see the output from


All of these questions will determine how eth0, eth1 and your routing table need to be set up.
