| 10:57 | <eu^22tfn2Kalugan> 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.
| |
| 11:00 | <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?
| |
| 11:02 | !vnc-edide
| |
| 11:02 | <ltspbot> 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...)
| |
| 11:08 | <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

| |
| 12:47 | <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!
