I'm trying to set up my mandrake machine to be on my local network. Somehow I can get the Internet to work (I'm here), but I can't see any of the other machines on my network even though all IP address are 192.168.1.xxx -- how is this possible? I'm going through the same router as everyone else! Am I in some kind of stealth mode or something? I can't ping by hostname or IP address, but I am going through the router. Furthermore, I can't ping the router! But I AM going through it in order to connect to the Internet. The light lights up on the router and my machine, the Internet works, but I can't ping anything. Can anyone clue me in on what's going wrong? Thanks!

What is your subnet mask? What is the output of "ifconfig -a"?

-K.

My subnet mask is 255.255.255.0, same as on the windows machines in the network. ifconfig -a sends out:

From other machines I can't ping 192.168.1.45 or 192.168.1.46. I can't ping other machines from my linux box, either. Thanks for posting your reply!

Oh, and here is my routing information:

192.168.1.0 * 255.255.255.0 U 0 0 0 eth1

Do you have a firewall running on your Linux box?

-K.

I don't think so. I checked in the Mandrake control center, and there was nothing firewall related under "network." Also, when I installed the OS I didn't install the firewall. When I do ps -A I don't see anything that looks like a firewall -- what would it be called if it were running? But I don't think I have a firewall up.

Ah! I think I fixed it! I ran lisa config from the control panel and set up the machine to accept addresses from the local network (range 192.168.1.1-192.168.1.255). Then I tried pinging other stations, but noticed that it was pinging from 46 when I set up lisa from 45. I configured eth1n(46) down, since I don't need it anyway. Now I can ping machines on the network! It still isn't resolving host names, though. Maybe I have to set something else up? Also, I can't log into the machine from the windows machines, even though the other machines are in the IP range I specified and login/password matches what I configured on the linux box as a user. Maybe I should ask a separate question for this. Maybe samba needs to be configured. Although I CAN SSH to the machine now, so I'm very happy! But I still can't browse over the network, even when my login/password is correct. It must be a samba thing, right?

Okay... lets address one thing at a time. You now think you have network access corrected, right?

But you still can't resolve host names?

Do you have the proper nameserver entries in /etc/resolv.conf ?
