[K12OSN] LTSP server slow or unresponsive when internet connection is not present

[Barry Cisna]

Mathieu,

OK, Your second and third lines of hosts file are fine.
The top line needs to look like this:
-------------------------------------------------------------------------
127.0.0.1        localhost.localdomain localhost servername.domainname
servername
------------------------------------------------------------------------

( you dont have enough info as you have posted in your reply).
Do you have this listing at current?
If not add it as above. This very well could be your sluggish problem. I
bet if you do NOT have listed as stated here you can not do a vnc to the
server itself,either.
Let us know what you find for remedy.

Take Care,
Barry Cisna
