Fat client have internet but server doa
Hello everyone. *
I'm a teacher who had been using K12LTSP for many years on two 30 client labs and switched to Edubuntu and ltsp last year using only fat clients. *Things have been awesome, but today while trying to install Epoptes ran into a problem... *I have one wired connection on the server but had two eth connections showing in the network applet. *I removed the one that was indicated "never used" and now the fat clients boot and have internet but the server can't access internet. The one wired connection that is listed is "ifupdown (eth0)" and can not be edited... I should also say that I had students working on it last year playing around with the initial install and checking out what they could do with it. *The history file didn't look too scary and when my other server *that drove my classroom*died,*I grabbed this "test" box, slid it into place and just added users to it. *It has run well since power up with zero troubles until today. * I knew that I may have troubles down the road because I've been staring at the other eth1 "never used" for months... So now I'm kind of stuck... *Help!! -- edubuntu-users mailing list edubuntu-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/edubuntu-users |
Fat client have internet but server doa
Hello Steve, *Thanks. *It doesn't appear that the /etc/network/interfaces file is being used. *It is there but the server starts without a functioning network... *The interfaces file looks to be complete but just doesn't work. *I have removed the network applet but that hasn't changed anything...
As a matter of fact, the Ubnuntu box I'm sitting in front of right now with a static connection has an virtually empty***/etc/network/interfaces file. *All if has in it is:auto loiface lo inet loopback That's it.. *I wonder where the ip, gateway and other info is stored? * Right now the clients work, so things are temporarily ok.

Fat client have internet but server doa
OK, got it, Steve and thanks. *For some reason, the resolve.conf was empty- well, one commented line: *"Generated by NetworkManager"... *No nameserver was listed.
Now both the server and fat clients are back up and happy. *I'll try to finish up the Epoptes install tomorrow.

Fat client have internet but server doa
Yes, forgot to mention that resolv.conf if used properly as well once network-manager is gone, but you have to populate it! *
Glad you got it fixed!
