Network Config

Recommended Posts

Hi all,

I got 2008.1 up and running now, but problem is I can not connect to the net if the other computer on the network (running windows) is already on line. I had to turn off the router and turn it on again. I have tried to connect via MCC with out restarting the router, but it wont happen.


Any suggestions?


Thanks all

How did you configure the network card originally? Did you configure with DHCP or did you assign an IP address? And if so, was the IP address you assigned the same one as the Windows machine?

No I didn't assign an address. I just let the install do its thing.

OK. Can you post the IP address assigned to the Windows machine, as well as the Mandriva machine when both machines are on. Then we can see if there is some sort of conflict.


To get this under Linux, open a console window, and then type:


su (enter root password when prompted)
ifconfig -a


then copy and paste the information here so we can see. For Windows, you can get via the network icon by the clock, or you can open a command prompt and type:


ipconfig /all


and we can then see what is configured here. Ideally, what I need are:


IP Address

Subnet Mask

Default Gateway

DNS address


to get DNS address from Linux:


cat /etc/resolv.conf


then copy and paste here.

OK, so we have IP assigned to this machine. I also see DNS is which is your router. So, what we can try now is see if you can ping the router:




now if you see nothing, that means it can't see it. If you get some results back, they should look like this if it's working:


[ian@esprit ~]$ ping
PING ( 56(84) bytes of data.
64 bytes from icmp_seq=1 ttl=64 time=1.32 ms
64 bytes from icmp_seq=2 ttl=64 time=1.32 ms


that is just example from my machine. So, if you ping your router, you should get a similar type of reply. If not, then please post the results here so we can see what's going on.


If the Windows XP machine is on and it doesn't work, switch the XP machine off, then try again. Now, I then want you to power on the XP machine again, and get the IP from this machine - because if it isn't working, it could be that both these machines are trying to use the same IP address. As mentioned before, you can do this by clicking Start, and then Run, and then typing cmd and clicking OK. Then after this, type:


ipconfig /all


then you can post the info here so we can see if it's the same or different.


PS - thanks for the vote of confidence :thumbs:

Hi Ian,

Am on line now, both the windows and linux boxes running. No drama today. So when I pinged the router all was good.


Its only sometimes it wont connect. I am guessing that there is an address clash.


Whats your theory? Should I assign a permanent address to my linux box????

When you next get the clash, check both the IP's on each machine so we can see what is going wrong. I tend to allocate IP's statically rather than via DHCP - but if you do this, you have to make sure that the DHCP range that the router is giving doesn't include the IP that you are going to give manually to the Linux machine.
