<danboid>
epoptes can only have one machine as the admin but can multiple users on that machine both use epoptes simultaneously, if they are members of the epoptes group?
10:14
s/both/all
10:14
or is it designed to only be used by one admin user
10:18
<alkisg>
danboid: multiple users are supported
10:18
And you can use ssh -X to launch it from other computers
10:20
<danboid>
OK that's good to know

Howdy Everyone. I think the performance issues with LTSP5 machines has been corrected. I added the two lines from alkisg to lts.conf and the machines work fine. I'm still seeing very slow boot times for some machines that worked fine under Ubuntu 16.04 LTSP5 (non-Greek-PPA). They take several minutes sitting at "Loading
16:22
initrd.img-5.4.0-42-generic". These machines have gig nics and reach close to that bandwidth when I'm able to get to a console to test it. )
16:36
<alkisg>
pw77: try to remove quiet splash in order to see in which point the clients delay
16:36
!quiet
16:36
<ltspbot>
quiet: to enable the Debian kernel and initramfs to show up more messages, in order to better troubleshoot the boot process, remove "quiet" from /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default

<pw77>
I looked in /var//lib/tftpboot/ltsp/amd64/pxelinux.cfg/default but didn't find any instance of 'quiet'. I should have been more clear, these are amd64 machines
17:08
<alkisg>
pw77: if they're really taking time at "loading initrd", that's related to tftp speed
17:08
Which in turn is related to the ipxe or pxe stack or tftp server (dnsmasq?) version
17:08
There's no ltsp code involved there
17:09
<pw77>
Ok.
17:15
Thanks for the help so far. I think I have enough to do some more testing. I appreciate the help!
17:28
<quinox>
possibly unrelated, but I have 1 machine that boots incredibly slowly unless I configure a small MTU. Shoddy firmware or something
17:35
and it was nothing outrageous, 1500 was too much, 900 was fine

<pw77>
quinox Where is that MTU specified?
17:55
<quinox>
I did it in my DHCP server
18:01
<pw77>
Gotcha

That appeared to speed up the issue with initrd
