Re: LTSP and GCC

Pawel,

Not, there isn't a compiler included in the ltsp tree.  We do have it
for the lbe (LTSP Build Environment), but that runs on a server, for
building LTSP.  It doesn't include a compiler for the thin client to
run.

Make a group floppy add the desired users to this. Give the device ownership to this group.

Applications not working on thin clients


	Trying to run amaya on a thin client. Works fine on the server.
But the minute I try and run it on one of my thin clients it crashes with
a

Gdk-ERROR **: 86
  serial 108 error_code 86 request_code 51 minor_code 0

or

Gdk-ERROR **: BadValue (integer parameter out of range for operation)
  serial 109 error_code 2 request_code 51 minor_code 0

	This is not running a local-app.

	Any ideas

No user can start any local application except root.

Hello all,
I am able to run local applications with no problems Thanks for the
help, and great documentation.

But after setting NIS properly with

1.MERGE_PASSWD false.
2.MERGE_GROUP  false.
3.MINUID=0
4.MINGID=0 
5.all:  passwd group hosts rpc services netid protocols mail 

but only and only root can start off any local application.

and other users are getting following errors.

GLib-WARNING **: getpwuid_r(): failed due to: No such user 502.

** CRITICAL **: setup_ctrlsocket(): Failed to assign
/tmp/xmms_somebody.0 to a socket (Error: Permission denied)

I am now using xmms and gmpalyer to watch local movies, audios and with
local devices available at
 /tmp/cdrom 
 /tmp/floppy

And clearly it cannot push data into the network. 

what do i do to enable users to run those applications.
thanks for the Help.

Students w/o Internet permission

	I work in a publish school in the US and am considering LTSP for our 
younger students.  The problem is, a significant number of them have 
paperwork from their parents that forbid them from using the Internet 
while allowing them to use computers in general.  The way that we do 
this on our Macintosh systems is to sort students into two 
"workgroups."  One of them doesn't allow the user to launch certain 
programs, e.g. web browsers, FTP clients, etc. while the other one 
does.

	I know that Unix doesn't usually have anything like this.  I figured 
that my best bet was to set their shells to pdmenu and then manually 
install .xinitrc files in each account.  I could probably script this, 
but a savvy user could still use any text editor (or word processor 
with a Save As command) to change this.

	Does anyone have any suggestions?  I need to be sure that some 
students can run Firefox while others can't.  Any pointers are 
appreciated.  For background purposes, I've been running Unix and 
Unix-like systems (Linux, FreeBSD, NetBSD, etc.) in various ways for 
almost 9 years.

							Thanks in advance,
							Jaime

Re: Students w/o Internet permission

Jamie,
   1) Perhaps run Internet access through Squidguard and filter based on 
user. Everyone would be able to launch Firefox, ftp, etc. but only 
"authorized" students would be able to get to the Net.

   To ensure that everyone uses the proxy use iptables to redirect all 
controlled traffic (i.e. port 80, 22, etc.) through the proxy.

   2) Or perhaps just use iptables user tracking to intercept 
un-authorized traffic and null route it.

   As an aside: It would be interesting to do a study to see if there is 
any difference in the development of the students that have early Net 
access as to those who don't. Finding and parsing information on the 
Internet seems like an important skill set to have and it seems that the 
"have nots" will be at an educational disadvantage.

Create a group, webusers add all users who should be allowed to run the 
software.
Then run:
chgrp webusers /usr/bin/firefox
chmod o-x /usr/bin/firefox
chmod g+x /usr/bin/firefox

Repeat for all apps you want to restrict.
Voila.

Ciao
A.J.

Re: Students w/o Internet permission

Yes you can, the execution permission can be controlled by group. Just
split the students into 2 groups, allow and deny.  Change the
applications to permit only allow group execution and remove world
permissions on the app. Review the commands chgrp, chmod.  

Remember Macs now are just UNIX under the covers. ;)

Re: Students w/o Internet permission

Umm... couldn't you simply not give them write permission to the 
.xinitrc files? Make a user and group called "unpriveleged", set the 
owner of the .xinitrc to unpriveleged:unpriveleged, and set the 
permissions to 611.
