[gentoo-user] tftp config problem (ltsp)

[sean]

I am trying to get LTSP working here.
All appear on the right track with one apparent problem, tftp'ing the file.

When I boot a client it appears to pull in the network information but 
when it starts to tftp the file, I receive a message that the file is 
not found on the client display.

I have been following the instructions here, 
http://www.gentoo.org/doc/en/ltsp.xml
and of course alter to what I need for my system.
Am I missing something obvious or something less so?

			Thanks,
			Sean


Below is my in.tftpd file.
# /etc/init.d/in.tftpd

# Path to server files from
# Depending on your application you may have to change this.
# This is commented out to force you to look at the file!
#INTFTPD_PATH="/var/tftp/"
INTFTPD_PATH="/tftpboot/"
#INTFTPD_PATH="/tftproot/"

# For more options, see in.tftpd(8)
# -R 4096:32767 solves problems with ARC firmware, and obsoletes
# the /proc/sys/net/ipv4/ip_local_port_range hack.

# -l is passed by the init script in addition to these options.
#INTFTPD_OPTS="-R 4096:32767 -s ${INTFTPD_PATH}"

The tftp file looks exactly like the one specified in the instructions.

Here is the tail of the message log. If I am rading correctly, it looks 
proper and the client is trying to start the tftp session.

Are you using syslinux?  I'm not sure but shouldn't there be a
pxelinux.0 file in /tftpboot?

Sounds like you have had better success than me.

Since removed. Made no difference.

I am using what ever was emerged using Gentoo's instructions.
I have had a bit more success since last posting, but not full success.
Depends on what I put in the dhcpd.conf file for the filename entry.

If it specifies
filename "/pxe/pxelinux.0"; it will start the boot but finally halts 
stating cannot find kernel image: linux.

If it specifies
filename "/lts/vmlinuz-2.6.17.8-ltsp-1"; then I get the NBP is to large 
for memory error.


So far no luck getting past either point.

				Thanks

Re: [gentoo-user] tftp config problem (ltsp)

[sean]

Looked over the directory structure in the tftp directory compared to 
what was setup in the ltsp directory.
Found some differences.

Copied over a directory called 2.6.17.80ltsp-1 which contained all the 
needed files in proper placement to tftp under the same original name.
Adjusted some conf files to point where needed and my test laptop 
started to boot.

First problem I ran into here was due to the touch mouse hardware.
It caused the boot to hang or panic. I deactivated the touch mouse and 
the boot restarted and progressed further till another problem.
During the boot process was getting error notices about not being able 
to connect to the nfs server.

Did some research and found this sometimes occurs when the speed of the 
server nic is so much faster then the client nic. Apparently this showed 
up with the 2.6 kernel.
Anyway, some more tweeks and had a successful boot and was greeted by 
the KDE login screen.

Logged in and was greeted by my usual desktop. Setting are still default 
so will play with them for such things as sound.

Decided to order a diskless workstation from 
http://www.disklessworkstation.com/ They appear to be a supporter of the 
ltsp project.
Also ordered an etherboot model, since that is an open standard.
Now when that shows up get to beat on it for a while.

         Thanks all for the help,
         Sean

They support the project so I figured one could not hurt.

why would you do that?  Coudn't you build an excellent diskless host
for less than they cost?  And their specs aren't very impressive...
