Joseph, I can't spot the problem either. And the dhcp3-server package in 11.10 is new to me (dhcp3-server - ISC DHCP server (transitional package)). But since your error references not being able to process your /etc/ltsp/dhcpd.conf file correctly, consider 1) backing it up and regenerating it 2) checking it's read permissions (ls -l ) 3) ensure that it's the correct config file (correct name/correct location)
I'll try to remember to check your dhcpd.conf file against mine when I get to work today. I think it's unrelated to your dhcp server issue, but make sure you work out your upstream device (eth0) which might require purging network-manager. And dont' forget to run *sudo ltsp-update-sshkeys* since you changed your nics. but maybe you knew all that... -peter On Sat, Sep 3, 2011 at 11:45 AM, David Groos <[email protected]> wrote: > Hey Joseph, > > Some things that come to mind... > > 1.
