telnetd is ONLY if you want to telnet INTO your server, which is not
what you are trying to do.

if you want to be sure of the IP address for that workstation, just tail 
the /var/log/messages file immediately after booting the workstation.  
You should see the dhcp reply message that shows what IP address it was.

Try telnetting using the IP address, rather than the hostname.

that is:     telnet 192.168.0.247 9200

As long as your workstation is booted, it should work.

ltsp-sound...and SIS sound onboard problem

Hello all,

I just setup a LTSP server running gentoo and a thin client.
It "all works perfectly" except the sound which i simply CANT make it
work!

I booted my ltsp client on runlevel 3 and nasd or esd simply *dont
start*.

nasd complains about something while opening /dev/dsp (which doesnt
work).

I have tried loading a lot of modules like sound, soundcore, sis, sisfb,
etc but none of them seem to create /dev/dsp.

Although when i load some of these modules, i get some new devices like
/dev/audio and /dev/sound/*

Can anybody help me? I RTFM on google for nasd+sis but couldnt find any
satisfactory answer anywhere!

PS: Im using ltsp version 3.x.
PS2: also i had to use a vesa driver on x-win for my onboard graphic
controller (couf...i use one of those cheap boards with
every'thing'onboard...).

Has anybody got a sis onboard graphic controller working properlly as a
lts client? If so, can you please paste a sample conf here?

Thanks in advance,
(Continue reading)

Re: LTSP4 and Local Applications

Dear Bryn,

I have setup LTSP4 with Local Application enabled. And I am using Mozilla 
Firebird 0.7 running as local app on thin clients. All I did was, I 
downloaded all the tarballs from ltsp website and compiled the whole thing. 
It took nearly 4 hours. Then I used the ltsp root. Then I unzipped the 
Mozilla Firebird tgz in the ltsp root. Copied all the required libraries from 
the main OS into the ltsp root. And Firebird was working as a local app on 
the thin clients. I have followed the procedure as mentioned by Jim. Only 
place I have deviated is that I am not using ssh to run the local app, 
instead I am using rsh. Reason being that I have nearly 40 odd thin clients 
and nearly 1000 users. 
I have added Flash plugins into the browser and copied the necessary library 
files into ltsp root. So far I have not faced any major problem with the 
browser except that it is a bit slow and needs 128MB RAM on thin client to 
work properly. I have also faced problem with javascripts ( on certain sites 
the button don't work properly ). Otherwise it is more stable than Netscape 
4.77 that was available with LTSP3.0

Just to add, my thin clients are used only for browsing internet and my setup 
is Mandrake Linux 9.1 with Icewm.

modprobe problem

Having installed LTSP4 on a fedora box, on boot up I get "modprobe: Can't open
dependencies file /lib/modules/2.4.22-ltsp-2/modules.dep".  The only other
post I could find regarding this was one from a guy who had built his own
kernel, but I have just used the stock build, any ideas?

Regards

Phil

Re: modprobe problem

Phil,

Any chance you didn't actually "Install" the ltsp-3 kernel package ?

If you grab the ltsp_kernel package from ltsp.org, and install it 
properly, it will put the kernel modules in the 
/opt/ltsp/i386/lib/modules directory.

Use local disk as root partition?

Hi,
  Suppose you have a PC you want to use as an X-Terminal, and suppose it
has a local disk. Now suppose you want to use that disk to optimize the 
system.
The first thing to do is, to use the disk to do the initial boot (after 
which the kernel
is loaded over the network). The second thing to do is to use part of the
disk as a swappartition (Done!).

The next thing you MAY want to do is reduce network traffic (will it 
...?) to the
X-Terminal by using a local partition as it's root. Would this reduce 
network traffic
(seriously)? If so, it's worthwhile investigating on how to do this. I 
would imagine
it to make sense to have the X-Terminal (during boot) synchronise it's 
local root
filesystem with the root file system available on the server. This may 
require
some changes in the initrd of the network kernel. First question though 
.. would it
be worthwhile in terms of reducted network traffic. After all, all the 
X-Terminal
does is run X.

Cheers,
  Erik

Right...

The errors are:

Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

Re: LTSP & Upgrade from RH8 to Fedora?

David - 

I couldn't agree more. Unfortunately those above did not see the same requirement.

Ended up building a replica of our existing setup on the Athlon with Fedora and tested all apps. Put this
aside as a standby replacement, then upgraded production server. Had to play the game that 'If you want it
done this way, I can't guarantee any form of success.'

All my CUPS printer settings were completely screwed by the upgrade, but salvageable. Those above who
complained about the printing issues had to suffer in silence. Or perhaps I just didn't hear them.

And yes, I was sweating as each (fully tested) Fedora disk went in.
