Hi! I have a problem. Intel NUC terminals RX is 100 megabits with a gigabit channel (TX is 1000 megabits, ok). ltsp 20.04-1~ubuntu18.04.1, linux mint 19.3, Chrootless.

<alkisg>
eu^22tfn2Kalugan: how do you measure, with epoptes lan benchmark?
11:01
<eu^22tfn2Kalugan>
epotes: iperf
11:01
epoptes and iperf
11:01
readings are the same
11:02
<alkisg>
eu^22tfn2Kalugan: I don't have much time, do you mind if I see for myself?

vnc-edide: To share your screen with me, open Epoptes → Help menu → Remote support → Host: srv1-dide.ioa.sch.gr, and click the Connect button
11:02
<alkisg>
It sounds to me like related to flow control...
11:04
<eu^22tfn2Kalugan>
A couple of minutes, approval needed
11:04
<alkisg>
ok, also boot the clients
11:05
(tell them I'm an LTSP developer, if it helps...)

<fiesh>
I can vouch for him, when I gave him access to our system, no files were del... oh wait a second!!!!!
11:10
<alkisg>
Hehe :D I thought `rm -rf /` was the same as chkdsk... :P :D
11:10
OK OK time to go, I'll be back in 3-4 hours, cheers
11:13
<fiesh>
hehe
11:18
<eu^22tfn2Kalugan>
Unfortunately, I can’t negotiate the connection. is it possible to solve in other ways?
11:19
rm -rf / don't offer ))
12:18
<alkisg>
eu^22tfn2Kalugan: do a network benchmark with epoptes, then upload the resulting screenshot

<alkisg>
eu^22tfn2Kalugan: oh, this happens with a single client as well?!
12:47
Is the client connected to the same switch as the server?
12:48
Do you have any services like firewalls that could be interfering?
12:51
<eu^22tfn2Kalugan>
This happens with terminals on intel NUC. Other terminals ok. This terminal was downloaded from the hard drive to ubuntu and the speed was gigabit in both directions
12:51
<alkisg>
eu^22tfn2Kalugan: that sounds like a kernel question (bug) then, not an ltsp question
12:51
<eu^22tfn2Kalugan>
Is the client connected to the same switch as the server? No, he isn't
12:51
<alkisg>
But do test on the same switch
12:52
As it might be related to MTU or other things that can be finetuned
12:53
<eu^22tfn2Kalugan>
ok! thank you!
