Hi, I'm a Linux newbie trying to use my desktop Edubuntu as a thin-client server for the other computers in my house. Because I was a bit nervous with partitioning my hard drive (there's WinXP running there too), I loaded the desktop version of Edubuntu ( 7.1.0)  through Wubi (whose alpha version didn't support the server edition). Configuration has been, shall we say, a challenge. Despite booting the clients to a rom-o-matic CD or (in the case of the computer whose BIOS supports booting to a network device) to the NIC, none has even got to the poing of being successfully assigned an IP address. I suppose it's possible that there's something wrong with the rom-o-matic CD I burned (or the other system's BIOS), but the fact that there are still basic unresolved issues with the NICs on the server suggests I should address those first: I think there's something wrong with my NIC configuration. At present, both eth0 (attached to my DSL modem) and eth1 (attached to my wired LAN) are controlled by DHCP - but I've tried all kinds of other combinations to no effect. I'm trying to use Firestarter as my router but Firestarter always fails on start, claiming that the eth1 connection isn't ready. During Firestarter's setup wizard, the DHCP settings section is grayed-out. In addition, I haven't been able to link to the LAN computers (while they're running Windows) through Samba (the appropriate Windows network name does appear in smb.conf). Regarding my Internet connection: on boot, Ubuntu loads what appears to be the correct ip info for my DSL provider on ppp0, but nevertheless provides only crippled access (the network connection manager shows a very limited number of packets being up and down loaded and, practically, I can't actually load anything in a browser). Running poff in terminal doesn't work as I get a "no pppd process for provider 'ppp0'" message. pon dsl-provider does activate a working Internet session on ppp1 using, for all intents and purposes, the same ip info (except that my ISP provides a new dynamic ip address). I really appreciate any help.
