[GRLUG] LTSP

[Godwin]

Hi Bill,

We use it at work.  I married RedHat 9 with LTSP a long time ago.  You
can get ROMs (to use from a floppy or serve from your DHCP/LTSP
server) from www.rom-o-matic.net

I would imagine most of it is already setup for you.  You just need to
tweak a few files.  Here's a typical entry on the dhcpd.conf file:
--------------------------------------------------------------
ddns-update-style none;
option domain-name-servers 192.168.37.2, 192.168.37.3;
option routers 192.168.37.1;
deny duplicates;
subnet 192.168.37.0 netmask 255.255.255.0 {
        option root-path "192.168.37.113:/opt/ltsp/i386";
        option broadcast-address 192.168.37.255;
        option subnet-mask 255.255.255.0;
        option domain-name-servers 192.168.37.2, 192.168.37.3;
        option domain-name "idcomp.net";
        option routers 192.168.37.1;
        range 192.168.37.11 192.168.37.99;
        }

# Boot from floppy.
host thinclient4.idcomp.net {
        next-server 192.168.37.113;
        filename "/lts/vmlinuz-2.4.21-ltsp-1";
        option root-path "192.168.37.113:/opt/ltsp/i386";
        hardware ethernet A0:50:1F:75:6B:C0;
        }

# Walmart PC - boot with PXE (sis900 nic)
host thinclient6.idcomp.net {
        hardware ethernet 00:0B:6A:3E:EA:84;
        next-server 192.168.37.113;
        if substring (option vendor-class-identifier, 0, 9) = "PXEClient" {
                filename "/lts/pxe/eb-5.2.4-sis900.zpxe";
        } else if substring (option vendor-class-identifier, 0, 9) = "Etherboot"
 {
                filename "/lts/vmlinuz-2.4.21-ltsp-1";
                option vendor-encapsulated-options 3c:09:45:74:68:65:72:62:6f:6f
:74:ff;
        }
        option root-path "192.168.37.113:/opt/ltsp/i386";
        }
--------------------------------------------------------------

Then look at the "lts.conf" file for specific workstation tweaks (ie.
sound, video, COM ports, etc.).  You need to export the home dirs and
fonts (via NFS): [/etc/exports]

/usr/lib/openoffice/share/fonts  
192.168.37.0/255.255.255.0(ro,sync,no_root_squash)

# Export /home for local Apps support in LTSP
/home                            
192.168.37.0/255.255.255.0(rw,sync,no_root_squash)
----------------------------------------------------------------

I believe that's it.  Download a rom for your specific NIC, write it
to a floppy then boot the workstation from it.  Not all PC's support
PXE booting, but I read somewhere that the newer versions of LTSP
support RPL booting as well.  Hasn't worked for me though.

cheers,
Godwin
