unable to configure network ifconfig works route fails

[akshay]

Hi,

I am having a strange problem with configuring the network, before I can get the installation going. I have the ipaddress, netmask, gateway address. During bootup eth0 is detected. I use ifconfig to setup the parameters as shown in the handbook :
ifconfig eth0 192.168.14.55 broadcast 192.168.14.255 netmask 255.255.255.0
This goes smoothly, but when I give the route command :
route add default gw 192.168.0.100

If gives the following error message for that :
"SIOCADDRT: network is unreachable"

I cannot ping any machine except my own. Running "ifconfig eth0" shows eth0 is UP.

Is there something I am missing?

lsmod shows the forcedeath module as loaded (which I think is the module for my lan card, which is an nvidia nforce2)

I am using the 2004.0 live cd.

Any help will be appretiated,

Akshay.

I thought your gateway needs to be on your subnet. Are you sure about the netmask/broadcast?

[akshay]

Geez ! I never thought of that. The ISP told me the netmask and I assumed it was correct! grrr! feel like an idiot..
I gotta rush and try it out. Thanks a ton. I shall come back and confirm if that was the problem.




I see light at the end of the tunnel .....

That fixed it. Thanks a ton.

Im off to install gentoo.

Hey I am having the same problem with route. Unfortanately I am not up on the lingo of networking. So I don't understand how the problem was fixed. So here is my problem

On my Gentoo Box,
I have my eth1 connected to the internet using dhcp
I have my eth0 connected to my other computer through a crossover cable. Eth0 is a dhcp server, which is working.

My other computer is running off the gentoo livecd (its an old computer) and it is recieving its IP and the such (from dhcp server, eth0). I can ping from my other computer to my gentoo box. BUT I cannot ping from my gentoo box to my other computer. When I do a
$ route add default gw x.x.x.x
on my other computer i get a "network unavailable"

On my gentoo box I have firestarter.


What I would like to do is do file sharing between the computers using NFS. I would also like to setup up NAT on my gentoo box so that I can surf the internet on my "other" computer. Here is the info from my gentoo box

$ ifconfig

On my "other" computer i have /etc/resolv.conf the same as my gentoo box, and it is getting the info from the dhcp server


I have searched and i don't know what else to do.

Hi,

I think that your eth0 has an ip address od 192.168.1.0. If I remember correctly numbeers ending in 0 and 255 are reserved for the network and broadcast addresses. Maybe you can give eth0 an address like 192.168.1.13 (or any other number instead of 13) using

ifconfig eth0 192.168.1.13 netmask 255.255.255.0 broadcast 192.168.1.255

Also from what I understood of what mseigneurin had mentioned, I think the gateway needs to be on the same subnet, which means that your gateway should also have an address of the form 192.168.1.14 (or some other number instead of 14). I suppose gateways need to have more than one IP address on for the network that they are on (which should be your network of 192.168.1.0 ) and one external network (24.222.209.10 or something, again you have a number ending in zero there).

I am not sure about what I have said above, its only what I understand of things. I hope im not way off the mark

Hope that helps.
Akshay.
