Thanks for the pointers Eric, I checked all the files you suggested but
I couldn't find anything amiss. I have done a reinstall today, disabling
the IPv6 option and everything went went OK. I think you were correct in
your guess about IPv6, I almost missed the option the second time round!
Is the any advantage / disadvantage in not installing with IPv6?
One issue though even installing with IPv4 the first entry in hosts was
::1 LTSP-2 localhost.localdomain localhost
Webmin was not happy with this arrangement and refused to play until I
modified it to
127.0.0.1 LTSP-2 localhost.localdomain localhost
This doesn't seemed to have caused any problems yet with the rest of the
system the terminal boots OK and the home folder in found.
Thanks for your many hours of hard work in making K12ltsp the superb
software that it is.
Best Regards
Peter
