Re: [Ltsp-discuss] client reboots continuously on LTSP 5

Ltspinfo seems like it is the right answer in 4.1, but I cant find it on my system. Is there anything else, other than running a ssh service on each client? In LTSP5 + Ubuntu, there's a program called 'student-class-manager'. It gives you a list of connected client with a preview of each station's screen. We can disconnect/blank the screen/chat with them.

[Ltsp-discuss] Help on dhcpd.conf for mix env
Hello all,
I took this part of dhcpd.conf from Jim Kronebusch yesterday :)
I have a situation where the LTSP5 clients is located in the same network as
the non-LTSP clients. Therefore I believe we can use the host declaration
based on MAC address.
But, I'm sure about the correct syntax. I need to setup DHCP on this case:
Clients are divided into 3 groups:
Group A: 192.168.0.1-192.168.0.10 (Non-LTSP clients)
Group B: 192.168.0.50-192.168.0.60 (Non-LTSP clients, notice the gap of IP
range from Group A).
Group C: 192.168.0.100-192.168.0.130 (LTSP clients).
This is the quoted dhcpd.conf:
authoritative;
# Main LAN IP Range
subnet 10.6.0.0 netmask 255.255.0.0 {
option domain-name winonacotter.org;
option domain-name-servers 10.6.1.50;
option routers 10.6.0.1;
option subnet-mask 255.255.0.0;
pool {
allow unknown-clients;
range 10.6.253.1 10.6.253.255;
}
}
# LTSP5 Clients by Mac address
group {
use-host-decl-names on;
deny unknown-clients;
if substring( option vendor-class-identifier , 0 , 9 ) = PXEClient {
filename /ltsp/i386/pxelinux.0;
}
else {
filename /ltsp/i386/nbi.img;
}
option root-path /opt/ltsp/i386;
host chsmain1 {
hardware ethernet 00:1A:4D:2F:A5:78;
fixed-address 10.6.252.1;
}
}
Cheers.

Re: [Ltsp-discuss] 2 balanced servers
HI, does this configuration need any other changes bedides these made in dhcpd.conf-files. I was just today trying to get two old servers work side by side. Managed to clients get ip from another and then mix the servers during boot up. Btw, firewall rules are difficult. I had to turn it off to get on...just to be sure that firewall is not the reason. This was when I was trying to nfs mount /home from the primary server. mikkoj Lainaus Asmo Koskinen [EMAIL PROTECTED]: Asmo Koskinen kirjoitti: After summer we get this two servers at school with 120 thin clients.

IMHO run ssh connect just for reboot/halt (a few times a year in some cases) is time (resources) waste. However, lots of people seem to want remote shutdown, so maybe I'll spend an hour tonight, and cobble together a quick ltsp5 remote shutdown wibbly-bit. Pls do NOT forget reboot feature.

I believe the following should do what you want. Of course use your domain
name server,
your router ip, and change mac addresses for fixed hosts. To add the other 28
LTSP
clients duplicate this portion for all needed clients:
host client1 {
hardware ethernet 00:1A:4D:2F:A5:78;
fixed-address 192.168.0.100;

I hope this helps you out. Jim
