<alkisg>
Heya brcisna, are you here?
15:47
<brcisna>
hi alkis yes here
15:48
<alkisg>
Do you have epoptes installed?
15:48
!vnc-edide
15:48
<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
15:48
<brcisna>
yes
15:48
<alkisg>
OK let's do taht ^
15:48
<brcisna>
ok
15:49
one second
15:54
<alkisg>
brcisna: which user has the problem?
15:55
<brcisna>
both brcisna and superuser are sudo users,neither can run sudo commands on clinet machine i get .Incorrect login.
15:55
<alkisg>
brcisna: note that they are not in the sudo group. Check "sudoers"...
15:56
<brcisna>
ok,, i will check on client machine via webin later,, they both work fine on server though?
15:56
<alkisg>
brcisna: no, on the server they are not in the sudo group either
15:56
I don't know what you call "file server", is it the ltsp server?
15:56
<brcisna>
i am sure i checked on client a few days ago and they were in sudoers file.i will check again though
15:57
<alkisg>
brcisna: they are in the sudoers file
15:57
<brcisna>
yes the ltsp server sorry
15:57
<alkisg>
They are not in the sudoers group
15:57
They cannot sudo on the server
15:57
See: sudo ls
15:57
Asks for a password
15:57
<brcisna>
ok alkis i will look on client machine image when i get home,,,
15:57
<alkisg>
It's probably a bad sudoers file. But why do you need sudoers instead of the sudo group?
15:57
<brcisna>
only way i know how to make sudo workk.
15:58
<alkisg>
sudo gpasswd -a brcisnasudo
15:58
sudo gpasswd -a brcisna sudo
15:58
<brcisna>
i guess never knew of sudo group,,i am old,,i guess
15:58
<alkisg>
This adds the user to the sudo group
15:58
Then, after `ltsp initrd` and reboot, the user will be able to use sudo
15:58
<brcisna>
ok ill do it that way Alkis,,thanks for the tip,,ill add this way when i get home from work
15:58
<alkisg>
sudoers can do that, but it's not the normal way to do it
16:00
<brcisna>
ok thanks i learned something here,,i guess dont understand why the same two users does work on ltsp server and image is copied as squash for client
16:00
<alkisg>
brcisna: they do NOT work on ltsp server
16:00
Can you see the screen there?
16:00
Do you see it asking for a password?
16:01
If you want "sudo" without password, the sudoers syntax is different, it's "nopasswd"
16:01
OK now check on the client
16:01
<brcisna>
ok let me try
16:02
i have to rebiuild image yes?
16:02
<alkisg>
No
16:04
Can you put the password there?
16:04
<brcisna>
i did yes
16:05
<alkisg>
Are you using the same password?
16:05
In both ssh and login?
16:05
<brcisna>
yes
16:05
<alkisg>
That's strange...
16:05
<brcisna>
same passwords
16:06
yes,,this did work ok,until about a month ago now
16:06
also i may mention if i use webmin to access files on the client machine the sudo users works,,
16:07
<alkisg>
Try again with the password there
16:07
<brcisna>
is there any chance webmin could be messing up the passwors on client wgemin has updated a couple times recently
16:07
ok l;et me try
16:07woernie has left IRC (woernie!~werner@pd9e8bc11.dip0.t-ipconnect.de, Ping timeout: 240 seconds)
16:07
<alkisg>
I don't know about webmin
16:08woernie has joined IRC (woernie!~werner@p578bb7b6.dip0.t-ipconnect.de)
16:08
<alkisg>
Ouch the VNC connection is too slow
16:08
<brcisna>
yes i have poor internet at our house
16:09
i dont want to eat up a bunch of your time alkis,,you have alot to do im sure
16:10
<alkisg>
brcisna: ok let's at least add the users to sudo group
16:10
On the server, type these:
16:10
<brcisna>
ok go for it
16:10
<alkisg>
sudo gpasswd -a brcisna sudo
16:10
sudo ltsp initrd
16:10
<brcisna>
ok second ill do this--
16:10
<alkisg>
Then on the next reboot you should be able to use sudo
16:11
I can't see your screen updating anymore the internet is too slow
16:11
So you need to do it
16:13
The client needs to be rebooted now
16:13
<brcisna>
ok those two commands done success
16:13
ok i do that from epoptes,,i never even use epotes
16:13
<alkisg>
Yes you can reboot it via epoptes
16:13
<brcisna>
ok thanks ill do that now
16:14
<alkisg>
Is there any way to have faster internet? E.g. some other time when you join from work?
16:15
<brcisna>
i just rebooted client alkis,,i apologize my home internet is slow sometimes,,sometimes it is fine
16:16
i am using a lot of your time i know
16:16
let me try and see if sudo work with my name now
16:17
<alkisg>
Aren't you sharing your work computer now? We shouldn't care about your home internet speed...
16:18
<brcisna>
ok i reconnected to you
16:19
sorry i am vpn to home
16:20
<alkisg>

16:20
And there
16:20
<brcisna>
ok great that worked,,Thanks!
16:21

16:21
<alkisg>
Can you put there in sudo?
16:21
To see if sudo works?
16:21
<brcisna>
rats still doesnt work
16:24
<alkisg>
brcisna: something is definitely wrong there
16:24
I don't think the problem is in ltsp
16:25
<brcisna>
Ok alkis,,, thank you for trying,,,you have spent a lot of time here..
16:25
<alkisg>
Do you want me to stop trying?
16:25
<brcisna>
i will google debain,,,forums.
16:25
no,,you can keep trying
16:25
if you want to try and figure it out
16:25
<alkisg>
OK, would you mind if we changed your password for a while, so that you tell it to me, so that I test? And then we can put it back
16:26
<brcisna>
yes thats fine just use whatever password you want
16:26* quinox hands alkis a cup of tea and some cookies
16:26
<brcisna>
or just use brcisna as password to remeber easy
16:26
<alkisg>
Thanks quinox :)
16:26
brcisna: put the old pass there
16:28
Put the new password as well; we were both typing :)
16:32
Ouch VNC got too slow again :/
16:32
<brcisna>
sorry
16:32
<alkisg>
Can you type this in the client terminal?
16:33
ps faux | grep brcisna
16:33
<brcisna>

16:33
i disconnected hang on
16:33
ill report here hang on
16:35
<alkisg>
Can I logout the user?
16:35
It's connected as brsicna, can I disconnect brsicna from the client?
16:35RaphGro has left IRC (RaphGro!~raphgro@fedora/raphgro, Quit: Please remember your own message. It'll be read as soon as possible.)
16:36
<brcisna>
yes
16:36
go ahead
16:38
<alkisg>
brcisna: do you have autologin enabled?
16:38
<brcisna>
no no autologin
16:39
<alkisg>
When I `login` at the terminal, a whole lot of GUI processes start running, goa daemon, gvfs volume monitor etc
16:39
Something is misconfigured there
16:40
But I lost the connection again
16:40
Let's try it another time when you have better internet, I got tired of waiting now :D
16:40
<brcisna>
ok alkis thank you,,for trying
16:44
<alkisg>
Yeah that's the problem
16:44
The first login or sudo or anything, works
16:44
The second one, when /home/brcisna is mounted, fails
16:45
<brcisna>
alksi i am using lxde as session manger could that be it?
16:45
<alkisg>
Why do you have pipewire, is lxde shipping with pipewire, or did you install any beta things?
16:46
<brcisna>
dont know what pipewire is,,i have many multimedia programs installed for doing vieo editing
16:46
never heard of pipewire,,,
16:47
i guess i never tried with using gnome as session manger ot see if sudo fail
16:49
<alkisg>
I renamed your .ssh directory to .ssh-bak
16:49
<brcisna>
ok
16:49
<alkisg>
Lets see if sudo works after reboot...
16:49
<brcisna>
ok you want me to reboot client
16:49
<alkisg>
I rebooted it
16:49
<brcisna>
you rebooted..
16:49
thanks
16:51
<alkisg>
brcisna: I think you have some service there that runs with your name
16:52
Without doing anything on the client, you already have processes running with your name
16:52
I think these are causing the problem
16:52
<brcisna>
ok,,,
16:52
like i said i have installed many multibedia things
16:52
<alkisg>
I think you configured some of them to run as brcisna
16:52
And they're causing files in use etc
16:53
You should either do a clean installation,
16:53
<brcisna>
alkis i think when i get home i will log into a regular gnome session and try sudo?
16:53
<alkisg>
or at least make sure, that after rebooting a client,
16:53
Do mate install
16:53
It's the recommended one, light and works fine
16:54
<brcisna>
mate ok,,i will try mate thanks
16:54
<alkisg>
Do not install a new desktop environment
16:54
The problem won't be solved by installing more programs
16:54
You either need to reinstall your operating system,
16:54
<brcisna>
i have just used lxde it is fast also
16:54
<alkisg>
or to make sure that no processes run as brcisna before login
16:54
When a client boots, do what I did
16:55
right click from epoptes, open root terminal, run ps faux| grep brcisna
16:55
If there are processes => wrong installation, reinstall the operating system
16:55
If there are not => OK, continue
16:55
<brcisna>
ok tahnks i write thisdown copy paste that
16:55
<alkisg>
OK
16:56
<brcisna>
alkis i have installs many arduino elated stalso
16:56
i cant even type,,,sorry
16:57
i will set password back to original password for my username
16:58
the strange thing is,, the sudo passwords do work on ltsp server itself
17:15
<alkisg>
No it's not strange
17:15
Files are in use in sshfs on the client
17:15
Because of processes before login
17:15
That's strange
17:16
That's the problem you need to fix
17:16
Or just reinstall
17:16
<brcisna>
ok will do thank you for all the help
