Re: Client time/date synchronisation

Hi Wolfgang,

I have done a new installation this morning using the i386-server-image instead of the amd64 one. Things definitely work much better now.

Client time sync without internet was not working for me with the default setting "ltspConfig: TIMESERVER=ntp". You suggested to switch to "ltspConfig: TIMESERVER=auto". This works for me appending "server" to /etc/ntp.conf. Syncing however happens with several minutes delay.

Thin client is also working using "ltspConfig: LTSP_FATCLIENT="False"". However, this setting is not what I prefer because it deactivates the possibility to boot as "diskless workstation" in the "primary subnet".

Removing "ltspConfig: LTSP_FATCLIENT="False"" and adding "ltspConfig: FAT_RAM_THRESHOLD=1000" should work but doesn't for me. I don't know why.

The fix for me was to remove "ltspConfig: LTSP_FATCLIENT="False"" again and editing the configuration in /var/lib/tftpboot/ltsp/i386/lts.conf by adding "FAT_RAM_THRESHOLD=1000".

Thanks a lot for your help fixing my issues.

Kind regards,
