If I do the 2 nic install how do the clients know to send their dhcp

Can I convert my current setup to the 2 nic or is it better to
reinstall?

A "Two NIC" setup is when your LTSP server is plugged into the school's network on one side (on eth0 for example) and on the other side is plugged into a switch that only goes to the thin clients (eth1 in this case). That way your thin client's DHCP requests never reach the school's DHCP server. Their traffic has to travel though the LTSP server. Here's an example.



----- LTSP server ---- Thin clients
                                  /                  |
Internet --- Firewall --- Schools servers (DHCP, File, Authentication, Etc.)
                                  \                  |
                                     \ Other Desktop PCs


The thin clients are segmented on their own network, separate from the rest of the school. Only the LTSP server is plugged into the rest of the network on the other network card.

This works well if all the thin clients are in the same room as the server (like in a lab, or you have one "server" per classroom). If the clients are scattered about with only a couple in each location and have to be plugged into the school's network, then the alternate DHCP port is probably easier. -----BEGIN PGP SIGNATURE-----
