<josefig>
good morning, something weird happened with the account of one of my ltsp clients
15:22
when he logs in the pc is not giving video, i assume is the video card
15:23
<mwalters>
josefig: are you able to see the mouse if you move it around? (e.g., left/right... I'm thinking maybe the client thinks it has another monitor attached, and the one you actually do have attached is not the primary)
15:24
I ran into this with some of my ITX motherboards with laptop style display connectors on the board
15:24
If you do see the mouse, then try opening a root shell w/ epoptes on that client and check xrandr to see what displays it sees
15:25
(you might just want to do that regardless)
15:26
<josefig>
no, i see like an error on screen_02 let me share with you
15:27
libglib-2.0.so.0.5600.3[7f626b029000+113000]
15:28
<mwalters>
is that the only thing given?
15:29
<josefig>
light-locker[1652] trap int3 ip:7f626b07ae11 sp:7ffc93151430 error:0 in libglib-2.0.so.0.5600.3[7f626b029000+113000]
15:29
<mwalters>
probably try to open a VT and check /var/log/xorg logs
15:29
and syslog

<alkisg>
josefig: do you have epoptes?
15:37
!epoptes
15:37
<ltsp>
epoptes: Epoptes is a computer lab administration and monitoring tool. It works on Ubuntu and Debian based labs with LTSP or non-LTSP servers, thin and fat clients, standalone workstations, NX clients etc. More info: http://www.epoptes.org
15:38
<alkisg>
Epoptes can help you access the client logs while xorg is still running, even black, and some times you can also see the client screen via vnc even though it's not displayed locally
15:39
<josefig>
i see the problem is only with that account, i logged into that pc with my account and worked
15:39
some kind of lock or something
15:39
the other accounts worked, i thought was something with the pc
15:39
but nope
15:40
<mwalters>
probably try the problem account on another PC to be sure. Did you copy ~/.config from another server for that account?
15:41
<josefig>
nope
15:51
i removed the .Xauthority and worked
15:59
<alkisg>
Maybe he ran "sudo something" at a point, and messed up his permissions
15:59
sudo find /home -uid 0
15:59
This will help you locate root-owned files, which is a problem

<mmarconm>
i installed ltsp on ubuntu server 18.04, the fat but when try to boot, tftp freeze, and i got a timeout
23:32
<quinox>
does it try to connect to the right IP?
23:33
<mmarconm>
yes
23:33
<quinox>
you can test the TFTP via command line from a running machine on the same network
23:33
perhaps a firewall is in the way
23:33
<mmarconm>
how i test ?
23:33
tftp via command line ?

23:34

23:35

23:35
and euh.. http://www.ing.iac.es/~docs/external/realport/ps-xxxx-tsht-tftp.html
23:37
<mmarconm>
thanks, will try
23:37
what is the diference betw ftp and tfpt ?
23:37
do u know wqui
23:38
quinox:
23:38
<quinox>
ftp is a real protocol, tftp is almost nothing
23:38
ftp runs on port 21
23:39
ftp has commands to get a list of all files, tftp doesn't
23:39
<mmarconm>
ahhhh tftp use udp
23:39
ftp use tcp, that garante the package delivery in good state
23:39
good, thankyou
23:39
<quinox>
(I wouldn't recommend FTP nowadays btw, the separate ports for data transfers are annoying + the binary/text difference can cause issues)
23:39
no problem
23:40
<mmarconm>
ahhh, was just a requestion, i am not planning to use ftp ahahaha
23:41
my friend was argumenting with about upd, he said that udp its used for send data and tcp to receive data
23:42
<quinox>
you can send and receive over both TCP and UDP
23:42
UDP is "fire and forget", packets can get delivered out of order or not at all - you have no guarantees
23:42
TCP sets up a proper connection which includes resending lost packages, making sure packages arrive in order
23:43
<mmarconm>
yes, tcp uses sync ack, tree hand shake to stablish conn
23:43
udp i think its used for streaming videos
23:44
<quinox>
yup yup
