<Chap>
What is the preferred password reset method for a nontrivial number of users (in my case, 150)?
08:18
From initial tests I'm guess ldm doesn't gracefully handle `passwd -e`
08:19
<alkisg>
Chap: password reset happens on the ltsp server from the sysadmin and isn't ltsp specific
08:19
You weren't asking for "how the users can change their password themselves", right?
08:20
<Chap>
Correct.
08:20
Along this vein: https://sourceforge.net/p/ltsp/mailman/message/29868064/
08:21markit has joined IRC (markit!~marco@host179-38-static.243-95-b.business.telecomitalia.it)
08:21
<Chap>
passwd -e expires the password, forcing an interactive password change at next login (via ssh at least)
08:22
<alkisg>
Yes, ltsp 5 doesn't support that, while ltsp 6 will
08:22
(if it ever gets developed)
08:22
<Chap>
LTSP5 is just too damn solid.
08:22
<alkisg>
So instead of expiring them, tell the users to change them?
08:23
There's a gui for the users to change their passwords...
08:24
E.g. setting the password to "1234" and telling them to login and change it, is one workaround...
08:24
instead of using -e
08:26
<Chap>
Dig it. Thank you sir.
08:27
<alkisg>
You can also easily add a menu in LDM for that, using just lts.conf
08:27
(to invoke an xterm to handle the password expiry prompts)
08:28
<Chap>
Ah ha! Yes! I've done that before for another purpose.. probably a motd or something.
08:28
OK cool. I drop those in /etc/X11/Xsession.d right?
08:29
<alkisg>
No, there's an lts.conf setting for menus
08:29
LDM_MENU_ITEM or something
08:29
<Chap>
Ah yes I see.
08:31
Well, I see the RC_FILE01... part
08:32
<alkisg>
Nope
08:32
LDM_MENU_ITEM_0="Change your password"
08:32
LDM_MENU_COMMAND_0="xterm -e command..."
08:33
Where command is the command that would get the user name and ssh to the server etc
08:34
<Chap>
Right on. Doc page? It's not in the lts.conf man pages I'm finding.
08:34
<alkisg>
I don't think anyone bothered to document it :)
08:36
<Chap>
Oh, fun.

<stephen^5ad76ee5>
Good Morning (here inthe UK). I recently installed LTSP GUI manager and, with some considerable, and much apprected, help from Alkisg, I managed to get a fully functioning system up and running...cont
08:45
but, I have just run an "update" on the image and it appears to have broken it
08:46
Same problem as I had when I first installed
08:47
prlem encuntered when "setting up nbd-client" at the bootup screen on the client
08:47
problem
08:48
any help would be welcome
08:53
<alkisg>
what is the exact error message?

<alkisg>
!client-list
09:02
<ltsp>
client-list: to get a list of all nbd-clients (which sometimes is the same as ltsp clients), run: netstat -tn | sed -n 's/.*:10809 *\([0-9.]*\):.*/\1/p' | sort -Vu

<Chap>
alkisg: Where would I see the results of an LDM_MENU_COMMAND_0 ? I set mine to /usr/bin/xterm -e /path/script.sh but nothing seems to happen when I click the menu item.
09:26
<alkisg>
try plain xterm with no params to see, you probably have a misteake
09:29
<Chap>
Yes sir - Plain xterm worked. Invalid path. Thank you.
10:35
Cheers

Stephen: (11:53:33 πμ) alkisg: what is the exact error message?
11:18
<Stephen>
hang on... i'll boot the client and check the exct wording... Back in a minute
11:20
seting up nbd-client ... error: socket failed: connection refused exiting

11:22
<Stephen>
pretty much identical to the original error message when I first installed and built the image
11:24
I should also say, I may have subsequently now muddied the waters futher by carrying out a "fix" as outlined in the pnp ubuntu main page. Which is:...
11:24
sudo -i sed 's/^dns=dnsmasq/# Commented by ltsp-pnp: dns=dnsmasq/' \ -i /etc/NetworkManager/NetworkManager.conf sed 's/^port=0/# Commented by ltsp-pnp: port=0/' -i /etc/dnsmasq.d/ltsp-server-dnsmasq.conf service network-manager restart service dnsmasq restart
11:24
Which was one of the fixes to a bug that has been identified with pnp ltsp
11:24
but whoch must have nothing to do with this problem becasue it has made no difference
11:25
I think this is what is technocally known as "groping in the dark" on my part....hahaha
11:26
<alkisg>
Stephen: now it's 14:30 for me, try to find me online tomorrow morning to help via vnc. If you messed things up a lot, it might be hard to restore them via plain chat.
11:28
<Stephen>
no worries Alkisg. I shall do a complete reinstall of my system (Ubuntu Mate 16.04 LTS 32 bit) and install the pnp LTSP GUI manager and then come back on here tomorrow
11:28
thanks for getting back to me. Hopefully catch you tomorrow
