Dear LiLuxer,
the next meeting will take place next thursday, april 27th.
There will be a presentation by yours truly about LTSP:
Linux Terminal Server Project. You'll get a short overview
of the technologies involved [1], the basic configuration of
such a system starting from a Kubuntu installation, including
a live demo of LTSP 4.2 in action.
Greetings, Eric
[1] tech: dhcpd, tftpd, pxe boot, nfs, xdmcp
Hi , i will give this week all the ideas i got a try, and i will inform you
of the outcoming.
Thanks for the help up to now.

Subject: Re: [Lilux-help] Kill stops too much processes
The father process receives a signal when one of its sons dies. The default
behaviour of a Unix process in this case is 'ignore', but it might be set a
different way, and the default behaviour of a signal that is not ignored but
unhandeled is 'kill' the process receiving the signal, so the father
process.
Other sons might not survive this situation, especially if they are not
completely independant from the father. As example, if they share pipes, and
the last writer or reader dies, they might consider this as an inacceptable
condition and stop.
I would also check the possible alias for 'kill' to make sure it was not
aliased a way or an another.
Lets try
> alias kill
or use \kill to avoid a possible alias.
Maybe the processes showns are actually not different processes, but
different threads in the same processus space. Can you confirm ?
I know also that there are 'light' forks on modern unices. They actually
share the same memory area, and separate the memory pages only in case of
writing. This is not far from the thread situation. Maybe it is the case
here.
I think you should send an another signal than -9 in order to stop this
process. -9 is quite hard, as the process has no chance to catch it: it is
no more executed at all. An another signal, unhandeled, as -HUP, gives the
process the possibility to close a cleaner way.
Tell me if it helps.

Hi , to all Lilux Users,
We have migrated some of our AIX and Solaris Programs to Linux with some
success. We are
hitting only smaller "features" like this one where we find no real
explanations , even by googling.
So the problem is when we kill one process all the processes of the user are
killed. But to make it
more complicated not all the time , so it is not reproductible.
If someone knows a hint to this .
Thanks in advance

Hi
A friend of mine gave me an UPS. It's a strong part as it has 850VA.
The only thing about it is that I can find no documentation on it. It has a
female sub25 on his backside. I suppose it's a serial port.
It is A Microferrups BEST QME850VA UPS.
Any idea?
Al
Hi
I've configured a little test server with a LAMP system.
Thus, here is every port closed, so to go on Internet, >I have to use
our proxy.
Everything works fine, except that my script in php doen't reach out
the wide internet world. Traffic must go through a proxy.
How must I configure php.conf that the php (http) server uses the proxy
to go on the internet?
Thanx.

Just FYI, Lilux AG is 19h00 as stated on the written convocation.

Hi,
I have a strange problem... I have a box running ubuntu dapper, and all
is fine.
Now I cloned the disk, and put it into another box which is 100& the
same hardware, and it still works fine, apart of one thing...
What was eth0 and eth1 before is now eth2 and eth3 :-/
root@box:~# ifconfig -s -a
Iface MTU Met RX-OK RX-ERR RX-DRP RX-OVR TX-OK TX-ERR TX-DRP
TX-OVR Flg
eth2 1500 0 1071 0 0 0 638 0 0
0 BMRU
eth3 1500 0 0 0 0 0 0 0 0
0 BMU

0 LRU
sit0 1480 0 0 0 0 0 0 0 0 0 O
root@box:~#
How can I go back to eth1/2 ?
Best regards,
Yves
p.s.
The NICs are an e1000 and a via_rhine, and unfortunately I found no way
of forcing the interface name on module load, that would be my preferred
solution...
Hi,
we are in the process of setting up a new web- and mailserver, and
consider switching from sendmail to another mail agent...
At the risk of launching a flamewar, which one would you recommend from
a security and maintainability point of view?
Best regards,
Yves
Hi,
as the subject says - can you tell me Free Software - related events in
french-speaking regions (ok, limit that to european countries) that are
of a certain size and level an thus merit visiting or participating in?
I'm not talking small install fests here, but rather larger events - I
am aware of the FOSDEM and RMLL, are there other such events around?
Somehow, I know much more stuff happening in german-speaking regions...
TIA, Eric
