Greetings,
I have four LTSP Terminals that all have the same hardware.
Occasionally, one or another of the terminals will not boot, giving an
error:
No 'root-path' recieved from the DHCP server
Three out of the four terminals are booting. I also have a couple of
VMWare computers that boot as LTSP clients no problem. The dhcpd.conf
file has defined option root-path defined.
We do have two dhcp servers on the network - we have Windows ISA server
that I am going to get rid of soon. I do not see anything the Windows
Event Log to indicate it is interfering with the process. Also, the LTSP
client is getting the dhcp lease from the corrrect server and is
downloading the kernel.
There do not seem to be any errors in the log files either.
The first time this happened was a few days ago with one terminal. The
problem went away despite my tinkering. Now we have the same problem
with another terminal.
I also seem to recall someone haveing problems like this due to
inaccurate computer clocks - so I have checked the bios clock on the
terminal and the time on the server and they seem fine.
Any ideas of what to look for would be appreciated.
