Internet connection lost after setting up thin client
« on: October 02, 2007, 10:33:45 pm »
So I have been testing LMCE for a few weeks now and so far it is working out pretty well. That is except when I set up a thin client. I can get the thin client to load with minimal effort and it works nicely. But soon after I loose internet connection from both the client and the core. I remember reading somewhere that some people prefer using 2 Ethernet cards when using thin clients. I assume one as a gateway and the other to manage the clients. I don’t know if that has anything to do with my problem or not. As it seems I am unable to even log into my router at this point. I get a timed out error.
Core: Broken :(

That could be related to a single NIC setup I guess.  Can you paste the output of the following command (executed on the core) in here the next time that happens?
Code: [Select]
sudo ifconfig

is the rest of your network on a 192.168.80.X? do you have eth0 set to use dhcp to configure its network settings or did you set them manually?

Looks to me like the external network card refreshed it's IP# using DHCP and got a new one from the virtual internal network interface's DHCP server. 

It's a typical single NIC setup problem I reckon.  Either use two NICs as it was intended or configure the external NIC manually.

It is set up to use DHCP to configure the network.

Being that I am somewhat inexperienced with setting up network protocol are there any common steps I could use to get my Internet back and just forget the thin client for now?

I think you just need to adjust some settings in the web admin under Advanced>Network>Network Settings and configure eth0 manually with a static IP number etc.
