LTSP server TFTP file not found error

I am trying to configure LTSP client on Red Hat 8.0,

Server is configured and when try to boot client
it say

.............
..Me192.168.1.9 Server 192.168.1.55
Loading 192.168.1.55:/tftpboot/lts/vmlinuz.ltsp TFTP error 1 (File not found)
Unable to load file
<sleep>
<abort>
Probing for pci nic ...
Probing for isa nic....

but vmlinuz file is present over there.
I tried changing the path /lts/vmlinuz-2.4.26-ltsp-2 in the dhcpd.conf but then also it doesn't works.


Any idea ??

I had the same problem. this path filename "/lts/vmlinuz-2.4.26-ltsp-2"; is the correct path in my config (RH9). After changing the path did you restart dhcp? I know it sounds stupid, but I did that exact thing heheheh. After a "service dhcpd restart" everything worked!

Yes, I had started the dhcp service after configuring dhcpd.conf file.

Will you post the contents of your dhcpd.conf file?

the last line should look like this....
filename "/lts/vmlinuz.ltsp";

Since you are not using the default ip address range of 192.168.0.1 ~ 254, you need to be sure to go through all of the files and make sure they use your ip address range.
/etc/exports
/etc/hosts.allow
/etc/rc.d/init.d/nat
/etc/hosts
/etc/dhcpd.conf
/opt/ltsp/i386/etc/lts.conf
/opt/ltsp/templates/k12linux/hosts-update.sh
/opt/ltsp/templates/k12linux/setup-update.sh
/opt/ltsp/templates/k12linux/ ( check for proper domain name and ip address )

Here is what my dhcp.conf looks like...

Code:
# Sample configuration file for ISCD dhcpd
#
# Don't forget to set run_dhcpd=1 in /etc/init.d/dhcpd
# once you adjusted this file and copied it to /etc/dhcpd.conf.

Your posted dhcpd.conf file shows the path "filename "/tftpboot/lts/vmlinuz.ltsp";" and I believe it needs to be "filename "/lts/vmlinuz-2.4.26-ltsp-2"; " without the outside quotes. Then reboot dhcp and it should work.

Here is a difference in my /etc/exports

/opt/ltsp/i386 192.168.0.0/255.255.255.0(ro,no_root_squash,sync)
/var/opt/ltsp/swapfiles 192.168.0.0/255.255.255.0(rw,no_root_squash,async)

Can you put this into the dhcpd.conf > Change the addresses to match your setup.
Don't forget to restart the dhcpd service after making these changes.


shared-network WORKSTATIONS {
subnet 192.168.0.0 netmask 255.255.255.0 {
range dynamic-bootp 192.168.0.2 192.168.0.50;
use-host-decl-names on;
option log-servers 192.168.0.1;

# trick from Peter Rundle <peter.rundle@au.interpath.net>
if substring (option vendor-class-identifier, 0, 9) = "PXEClient"
{

The dhcpd.conf has a line filename "/lts/vmlinuz.ltsp";
but you have it in with one hardware address.

{
hardware ethernet 00:E0:4C:E1:A8:16;
fixed-address 192.168.1.9;
filename "/lts/vmlinuz.ltsp";
}

It needs to be in brackets by itself...

{
filename "/lts/vmlinuz.ltsp";
}
