Is it just me, or is LTSP a mess?

As far as I have been able to tell, italc works great on 8.04+ (make
sure you have an up to date version of italc installed, and if it is
causing problems for you, let us know what they are and we can help.)
I personally use italc on 8.04 without issues... there are some tricks
though, like pointing to the clients u want via their server ip (as
mentioned in an email I sent a while back to the list):

The way to use italc with thin clients is adding or localhost and
the portnumber 10000+last byte of IP. For example... the client IP I want to
connect to is:, then connecting to this user from the master Italc interface
would be:

Some users have mentioned it requires the actual IP of the server (ie.

TCM is no longer supported... don't use it...

I'm sure there are other fixes along with documentation now being up
to date, but most of the changes are LTSP centric (ie, people from
different distros work together and then port these ltsp changes to
all new distros.) In essence LTSP on Fedora, Ubuntu, Debian and Gentoo
and (though a little different, still based on the same work) Suse all
work the same because its the same code under the hood.

Whatever changes have been made to other items (gnome, X, open office,
firefox, etc) are related to the distribution you are using... and
whatever changes have happened to that distro.

For any fine tuning, lts.conf is indeed the place to do that, and like
you say, won't be going away any time soon, but has been automated to
the maximum extent possible. video _should_ work an most thin clients
out of the box, if it doesn't let us know the video card in question
so we can take a look.

The documentation now presents all the possible values that can be put
in lts.conf, if you find there are items required, let us know and
we'll add them...
Can u let us know what non existent file its pointing to, so we can fix that?
