LTSP/SLED10

From openSUSE

Installation

• Install SLED 10 SP2
• Add SLES 10 SP2 repository via YaST2 Installation sources module, this is where server packages will get installed.

 cd /usr/bin
 wget -c http://forgeftp.novell.com/kiwi-ltsp/ip-easy-ltsp-config.py
 chmod +x ip-easy-ltsp-config.py

• Add openSUSE:Tools and server:ltsp repositories

There may be complaints about missing squashfs and easy-ltsp, ignore and continue.

Configuration

• Use "traditional method" for network configuration, give static IP 10.0.0.254 to the internal interface on the server.
• Edit /etc/sysconfig/kiwi-ltsp "DHCP_Interface=ANY", change "ANY" to the interface your dumb clients are on.
• Turn off firewall to the interface connected to internal network.
• Run the following to configure all the services:

 kiwi-ltsp-setup -c

If you give any other IP address change /etc/sysconfig/kiwi-ltsp''' "SERVER_IP" variable accordingly.

Troubleshooting

• If a client gives a "Could not find rootfs..." error during boot you need to remove the "COMBINED_IMAGE=" line from /srv/tftpboot/KIWI/config.default
• If a clients screen starts blinking after most of the boot process is finished you need to change "CONFIGURE_X=False" to "CONFIGURE_X=True" in /srv/tftpboot/KIWI/lts.conf
• If clients mysteriously can't find a DHCP server to start the TFTP boot process the dhcp daemon may have died. To check open a terminal and type "rcdhcpd status" if the output says "dead" issue an "rcdhcpd restart" I wrote a little bash script that issues "rcdhcpd restart" and put it in /etc/cron.hourly. I am not sure what is causing this issue but one hint might be in /var/log/warn where it reports "dhcpd: Can't create new lease file: Permission denied". Issue "less /var/log/warn | grep dhcpd" to check that.
