Hi, ltsp-cluster isn't supported in upstream LTSP anymore, so I'm marking this "Won't Fix".
We'll remove all references to ltsp-cluster from the LTSP code in the next big version, unless someone that wants to maintain ltsp-cluster (or wishes to sponsor its development) steps up and does it.

Firstly, I ask that writing mistakes be ignored, as I am not fluent in the English language yet.

I recently had to configure an LTSP-Cluster boot server on Ubuntu 16.04.6 LTS and did the following:

1 - I copied the getltsp-cluster script from https://github.com/opinsys/ltsp/blob/master/client/getltscfg-cluster/getltscfg-cluster to the "/usr/bin" directory located in chroot

2 - I changed line number 116 of the "/usr/bin/getltscfg-cluster" script to:

    echo INTERFACE_MAC = $ (ifconfig | grep $ {INTERFACE} | cut -f9 -d "")> $ cache_info

3 - I granted execute permission to the "/usr/bin/getltscfg-cluster" script

4 - I changed line number 28 of the "/usr/bin/ltsp-cluster-info" script located in chroot to:

    INTERFACE_MAC = $ (/ sbin / ifconfig | grep $ {INTERFACE} | awk '{print $ 5}')

5 - I updated chroot with the command ltsp-update-image

After performing the steps described above, I booted a thinclient pxe and it was properly registered in the LTSP-Cluster Control Center.

Ooops, sorry for the typo.

INTERFACE_MAC = $ (/sbin/ifconfig | grep $ {INTERFACE} | awk '{print $ 5}')

[Rafael dos Prazeres (rafaelprazeres)]

Consider the following correction in comment # 2. Sorry for the typo again.

2 - I changed line number 116 of the "/usr/bin/getltscfg-cluster" script to:

echo INTERFACE_MAC=$(ifconfig | grep ${INTERFACE} | cut -f9 -d" ") > $cache_info

4 - I changed line number 28 of the "/usr/bin/ltsp-cluster-info" script located in chroot to:

INTERFACE_MAC=$(/sbin/ifconfig | grep ${INTERFACE} | awk '{ print $5 }')

Hi, LTSP5 is not developed anymore so there's no need to send code about ltsp-cluster...

The new ltsp is: https://ltsp.github.io.
