| 06:18 | <Suresh> Hi sir how to use x11vnc in ltsp over internet(Not local network)
| |
| 06:18 | <alkisg> Suresh: eh, you use it normally, can you explain where you had problems with it?
| |
| 06:19 | Here's an example, if you do this, then you VNC to me:
| |
| 06:19 | !vnc-dide
| |
| 06:19 | <ltspbot> vnc-dide: To share your screen with me, run this: sudo apt-get --yes install x11vnc; x11vnc -connect srv1-dide.ioa.sch.gr - this is a reverse connection, it doesn't need port forwarding etc.
| |
| 06:19 | <Suresh> I tried with x11vnc with local network(Same network) in ltsp, it's working but out side the or other network not working
| |
| 06:21 | <alkisg> OK if I understand you correctly, this problem is completely unrelated to LTSP, and you just didn't do the appropriate port forwarding for VNC to work
| |
| 06:22 | You need to enter your router settings and port forward 5900 to the VNC server
| |
| 06:25 | <Suresh> Ya sir, exactly i want to implement x11VNC server in my ltsp with out port forwarding method
| |
| 06:26 | <alkisg> alkisg => Internet => router (ip=1.2.3.4) => vnc server (ip=192.168.1.123)
| |
| 06:26 | alkisg cannot access the vnc server without port forwarding in this ^ setup
| |
| 06:27 | It's a limitation of NAT networks. If you have NAT (normal router), you need port forwarding

| 06:40 | woernie has left IRC (woernie!~werner@p57A0E783.dip0.t-ipconnect.de, Remote host closed the connection) | |
| 06:42 | <Suresh> Exactly i want to know this operation sudo apt-get --yes install x11vnc; x11vnc -connect srv1-xx.xx.xxx- this is a reverse connection, it doesn't need port forwarding.
| |
| 06:42 | please help me.
| |
| 06:44 | <alkisg> Suresh: it doesn't need port forwarding from you, because *I* did port forwarding
| |
| 06:44 | You need port forwarding at least on one of the sides
| |
| 06:48 | <Suresh> Sir Please help me. How to do this (Brief)
| |
| 06:58 | ??
| |
| 07:01 | <alkisg> Suresh, this isn't related to LTSP, I've sent you a PM in case you want to hire me to help you with port forwarding etc
| |
| 07:02 | <Suresh> ok sir please sent the details
| |
| 07:03 | <alkisg> Can you see the "alkisg" tab where I'm talking to you in private?
| |
| 07:03 | <Suresh> I closed it sir.
| |
| 07:03 | ok got it sir.

| 13:39 | <elec332> Hello. Is it possible to mount samba shares with password on a ltsp 19 client?
| |
| 13:40 | Normally you'd use pam_mount.so, but that doesn't seem to work in this case
| |
| 13:40 | <vagrantc> ah, ltsp 19 does mess with pam a bit; it might be overwriting some configuration?
| |
| 13:41 | look at the relevent configuration files in /etc/pam.d/
| |
| 13:41 | from a booted system
| |
| 13:42 | <elec332> Is seems to be using a fake user of some sort. I added extra mount entries in the Pam files, but they are ran before the user logs in
| |
| 13:45 | <vagrantc> it uses the users from the server and effectively adds them at boot... there's a way to disable that behavior and manually configure if you use some other authentication scheme
| |
| 13:46 | <elec332> I use LDAP, so I already have the empty 54.sh file

| 14:55 | <alkisg> elec332: with an empty pam-54.sh override, ltsp shouldn't be any different from normal non-ltsp clients
| |
| 14:56 | (you could use OMIT_FUNCTIONS=xx in ltsp.conf instead of an empty pam-54.sh file)
| |
| 14:56 | Also, there's nothing about "fake users"... what user do you mean?
| |
| 15:00 | vagrantc: ltsp 19.12 has been tested without users reporting any issues; you may upload it to unstable if you want
| |
| 15:00 | It solves some issues with fuse3 in unstable
| |
| 15:00 | *testing too
| |
| 15:01 | <vagrantc> will be a week at the earliest, but yay :)
| |
| 15:21 | <elec332> I have mount.so in common-password and common-auth
| |
| 15:21 | And both get executed before a user logs in
| |
| 15:21 | And not when a user does log in
| |
| 15:25 | <alkisg> elec332: if you cat those files after boot, aren't they are you expect?
| |
| 15:25 | From what you describe, ltsp has nothing to do with pam in your setup
| |
| 15:30 | Nikoh77 has left IRC (Nikoh77!~Nikoh77@host148-135-static.9-79-b.business.telecomitalia.it, Remote host closed the connection) | |
| 15:31 | <elec332> The Pam files still contain the mount.so entries on the clients
| |
| 15:32 | <alkisg> elec332: do you see them modified by ltsp in any way? They shouldn't be
| |
| 15:32 | I don't think LTSP touches your setup; something else sounds misconfigured,
| |
| 15:32 | <vagrantc> /8/8
| |
| 15:32 | <alkisg> also, pam-auth is called at user login, I'm not sure what you mean "executed before a user logs in"
| |
| 15:35 | <elec332> The problem is they are called before the user logs in, as user gdm
| |
| 15:36 | <alkisg> Whatever you did there, should be unrelated to ltsp, and it should be the same as if it was a non-ltsp client
| |
| 15:36 | LTSP didn't touch pam, didn't do anything with GDM etc
| |
| 15:36 | <elec332> When the system boots up, right before you are taken to the login screen I see the error messages from pam_mount failing to mount
| |
| 15:37 | OK, I'll see what's borked
| |
| 15:37 | <alkisg> That sounds like you put them for gdm too
| |
| 15:37 | So gdm runs them for the gdm user when it starts
| |
| 15:37 | mgariepy has left IRC (mgariepy!~mgariepy@ubuntu/member/mgariepy, Quit: Leaving) | |
| 15:37 | <alkisg> But again, not related to ltsp at all; it sounds like you're following some broken how-to
| |
| 15:39 | <elec332> It's not gdm, I just deleted its home folder and it hasn't reappeared after a reboot
| |
| 15:40 | <alkisg> pam-auth gets called even without a home folder

| 18:56 | <alkisg> The new ltsp doesn't have screen.d at all
| |
| 18:56 | You just define a session however you want it
| |
| 19:07 | <test-94354> it is very good
| |
| 19:10 | I can use the distr Linux Mint 19?
| |
| 19:11 | <alkisg> Yes
| |
| 19:52 | <elec332> Is ltsp19 tested against Ubuntu 18.04 or 19.04?
| |
| 19:54 | Because with a clean install (18.04) with ltsp and LDAP I get the following issues:
| |
| 19:55 | Libre Office doesn't work. Firefox prompts everyone to make a profile. Konversation (KDE app) irc client doesn't work. And mounting samba in Pam doesn't work either
| |
| 19:55 | <alkisg> elec332: it's tested in 16.04, 18.04, 18.10, 19.04, 19.10, and 20.04
| |
| 19:57 | elec332: start with a normal installation, then start tweaking things, so that you know which of your tweak broke things
| |
| 19:59 | elec332: it's very possible that sambe home has issues; noone tested that
| |
| 20:03 | But of course that's completely unrelated to ltsp

| |
| 20:32 | I'll fiddle with permissions for it this weekend
| |
| 20:32 | <alkisg> It's usually a problem with remote locks

| 20:32 | Not permissions
