| 15:46 | <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
| |
| 16:07 | woernie has left IRC (woernie!~werner@pd9e8bc11.dip0.t-ipconnect.de, Ping timeout: 240 seconds) | |
| 16:07 | <alkisg> I don't know about webmin
| |
| 16:08 | woernie 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> Please put your password there
| |
| 16:20 | And there
| |
| 16:20 | <brcisna> ok great that worked,,Thanks!
| |
| 16:21 | appriciate your help
| |
| 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> ok second
| |
| 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?
| |
| 16:35 | RaphGro 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
