OK I made SSH_ASKPASS work properly, no need for pxssh
04:47
Just sshfs

highvoltage: it's too late to put only sshfs (=40kb) in the buster live .iso, right?
07:56
<highvoltage>
alkisg: yes
07:59
<alkisg>
I verified that only sshfs is needed to "netboot debian-live.iso using ltsp19, with ssh authentication and sshfs homes", so it would be fun to use it as the first test case, but np, in the next one :)

Hello team my question is about the network comsumption of an PXE boot terminal whe are having some performance issues and somethimes the terminal hangs, the network team says that they see a lot of reconnections between the terminals and the server and a lot of bandwith traffic

fjag79: thin or fat clients?
16:56
!fatclients
16:56
<ltsp>
fatclients: Nowadays LTSP supports thin and fat clients. They are both diskless and netbooted from the same LTSP chroot, but while thin clients run the session on the server and transfer the screen, fat clients run the session locally with their own CPU/RAM, thus performing amazingly better. See also !ltsp-pnp and https://help.ubuntu.com/community/UbuntuLTSP/FatClients
16:57
<fjag79>
I think they are fat clients but without hardrive
16:59
<alkisg>
There shouldn't be any reconnections at all
16:59
But to know more, you need to tell us more about your setup
17:00
E.g. booting a fat client might need 80MB
17:00
Loading libreoffice, 120MB
17:00
But... what distro, version, ltsp version, how many clients, gigabit networking or not...
17:00
all those matter
17:05
<fjag79>
ok we are using LTSP on debian 8.10 we are working with at least 25 client per server using gigabit connection but we use vmware to virtualize the ltsp server
17:06
the client uses libre office the calc, firefox, chrome and we install the citrix receiver because we need it to work with a custom app
17:09
<alkisg>
ok it sounds like you shouldn't be having any networking issues then
17:13
<fjag79>
ok should I need to validate some network configuration by my side so I cant guaranteed to the Network Team That my config is ok because the only network config I usually make are config the network address and define the network range no change on mtu or other network parameters

!lan-benchmark
17:21
<ltsp>
lan-benchmark: If you have a mixed-speed network (gigabit server<=>switch connection, and 100 Mbits/sec clients<=>switch connections), then you might suffer from the !flow-control issue. To benchmark your LAN with epoptes, see http://www.epoptes.org/documentation/lan-benchmark
17:21
<alkisg>
You can measure your lan speed with that ^
