Title: Internet connection lost after setting up thin client
Post by: fearingsept 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.

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.
