It disables flow control and enables NAT for 192.168.67.1, both of which are needed in LTSP

hi
05:19
im having a problem with my ltsp setup can anyone help?
05:22
I have a current samba4 setup with winbind configured but for some reason I cant log into my fat clients using the winbind users
05:28
I checked my auth log the users does authenticate however right after that it says session closed
05:30
<alkisg>
Are you using LDM?
05:33
<john____>
im using ubuntu fat client
05:34
<alkisg>
!fatclients
05:34
<ltsp>
fatclients: You may find some info about the Ubuntu/LTSP implementation of fat clients at https://help.ubuntu.com/community/UbuntuLTSP/FatClients
05:34
<alkisg>
That one? ^
05:35freedomrun has joined IRC (freedomrun!~freedomru@unaffiliated/freedomrun)
05:35
<john____>
yup
05:35
<alkisg>
Do you see this on your clients? https://dl.stgraber.org/images/ldm-natty.png
05:35
<john____>
yep
05:36
<alkisg>
LDM doesn't support samba or PAM
05:36
<john____>
so what do i use?
05:37
<alkisg>
There's no ready-to-use solution in LTSP
05:37
You need to switch to lightdm, pam, samba4, and custom scripts
05:37
<john____>
on another configuration i have samba4 server and ltsp i use likewise open and it works fine
05:38
<alkisg>
If you're only talking about server authentication, then you can still use LDM,
05:38
LDM uses ssh instead of PAM
05:38
So if you can login to the server with a samba user with ssh, then LDM can login too
05:38
<john____>
thats exactly what i can do
05:39
<alkisg>
But of course the fat clients then are no longer samba clients
05:40
<john____>
i can ssh in my samba users using winbind
05:41
just can log into my client
05:41
<alkisg>
What command are you using? ssh user\\domain@server ?
05:41
<john____>
ssh administrator@localhost
05:41
<alkisg>
!screen_02
05:41
<ltsp>
screen_02: To get a root shell on an Ubuntu thin client: https://help.ubuntu.com/community/UbuntuLTSP/ClientTroubleshooting#Using_a_shell_SCREEN
05:41
<alkisg>
Try from a fat client, not from the server
05:43
<john____>
ok thanks i will give it a go
05:48
<vagrantc>
alkisg: i think that's a bit intrusive to unconditionally mess with networking simply by installing a package like that...
05:49
<alkisg>
vagrantc: 192.168.67.1 has an "if" there, so it's not unconditional,
05:49
about the flow control, if you want an /etc/ltsp/ltsp-server.conf file, we can ship/document one, with e.g. DISABLE_FLOW_CONTROL=True,
05:50
<vagrantc>
alkisg: it's pretty unconditional for 192.168.67.*
05:50
<alkisg>
and of course personally I don't care at all, we already ship that in sch-scripts, I'm only mentioning it because there are users asking that functionality in MLs...
05:50
if [ "$ip" = "192.168.67.1/24" ];
05:50
...assuming that always means "internal ltsp subnet"
05:51
<vagrantc>
which is not true.
05:51
i see those sort of things as useful things to add to ltsp-config or some such
05:51
<alkisg>
We can adjust that part of the code to look at /etc/ltsp/ltsp-server.conf too
05:51
<vagrantc>
too intrusive for enabling by default
05:52
sure, if there were explicit enable/disable mechanisms, i'd be more ok with it.
05:53
<alkisg>
OK so an idea would be to "ship the if-up file, have it do nothing by default, but check the /etc/ltsp/ltsp-server.conf file or such, and then have ltsp-config create or modify ltsp-server.conf in order to enable the script features"
05:53
ltsp-config flow-control enable/disable, ltsp-config nat enable/disable etc
05:53
<vagrantc>
sounds reasonable to me
05:54* vagrantc thinks of cross-distro ways of doing it...
05:54
<vagrantc>
or rather, wonders
05:54
well, having a configuration file allows the implementation on a distro level
05:55
we set aconfiguration file, the ditro vendors decide how to implement

<john____>
hey mate so I have done what you linked me in the root shell on my fat client, I can ssh into my samba4 server however cant ssh into the local client. So do i need to configure ssh to start up as the client boots?

<alkisg>
LTSP clients don't have sshd by default, so it's OK if you can't ssh there.
06:36
But can you login to the LTSP server? (not into the samba server...)
06:36
From screen 02 on the client: ssh administrator@server
06:37
Exactly that, don't replace server or administrator...

<john____>
i have install ltsp and samba4 on the same server
06:47
on my previous setup i had samba4 on and ltsp on serperate servers and just used likewise and they could authenticate users with ease
06:48
so yes i can ssh into my ltsp server

<deyon218>
how can we modify user authentication for ltsp clients?
06:54
<alkisg>
deyon218: john____ is already asking about that...
06:59
<john____>
when i log into my ldm using the winbind users it does authenticate but then restarts immediately after
07:00
<alkisg>
Try the xterm session
07:00
From the LDM Preferences menu

how it could be possible ?
08:29
somebody could help to make ssh server work on thin client ?
08:31
<alkisg>
Remove all the ssh* lines from /etc/ltsp/ltsp-update-image.excludes
08:34
<jmilot>
i have only this : etc/ssh/ssh_host_*_key
08:34
i need to update the image?
08:35
<alkisg>
Yes
08:35
Also of course you need sshd installed in the chroot etc
08:36
<jmilot>
yes it already done
08:37
concerning sound, how it could work one time and not an other time (reboot between of the thin client)
08:39
could you explain how the /etc/ltsp/ltsp-update-image.excludes works ?

Hello guys
10:22
I need some help with configuring the ltsp clients
10:23
I currently have running old thinclients which boot fine
10:23
I have also some machines with pentium 4 processors
10:23
They are not working properly
10:25
They load the image but get a error: Could not open log file var/log/xorg.7.log
10:28
Can someone help me with this?
10:28
Maybe its because it uses Intel ??
