Re: [K12OSN] Need help integrating LTSP Server into school network

Is there anything that can be done about this problem without
resorting to buying another internet connection? Also, what should I
check before I plug the LTSP server into the network to prevent
anything catastrophic from happening (like disabling the school network)?

Yep.  Just make sure that eth1 is hooked up to the school network...and
NOT eth0.  Eth0 goes to the thin client segment *ONLY*, because that's
where DHCP is served.  Please do not get that backwards.  Physically
label your LTSP server's Ethernet ports if you have to.

But note that from one kernel version to another, Linux may detect your NICs in a different order. This normally doesn't cause trouble with updates because your ethernet hardware addresses are included in the configuration to subsequently tie down the device names. However if you re-install from scratch the eth0/eth1 names could easily be reversed. A safe way to check is to disconnect the main LAN side before the reboot following an install and make sure you can boot a thin client on the local side to show that your DHCP is going to the right place before reconnecting.
