iScsi almost done, fat clients and new chroot builder are in testing phase, fc18 downloading, and i designed a neat logo for the release =)

<vnc786>
how to ssh fat clients ? what i did 1. installed openssh-server in chroot successfully 2. KEEP_SYSTEM_SERVICES=ssh in lts.conf 3. updated ssh-keys & image
11:10
but still not working ..when taking ssh of fat clients from server it asks for rsa key...after y/n ? y --> password --> permission deny
11:10
any help on this ....??
11:12
<muppis>
Fat's doesn't contain any user accounts so you need to add one or set a root password in chroot.

<vnc786>
yes i have already set root passwd in chroot and i tried ssh root@<fatclient ip> still it gives ssh: connect to host 172.16.0.32 port 22: Connection refused
11:27
muppis: i have one admin account created in chroot in which i can login in tty1 and root in tty2
11:42
okay i have got ssh thru root but i was trying ssh username@<ip> -X....so does conclusion says ssh can not be taken using fat clients username ..???
11:58
<muppis>
No, because users are in server, not in clients. If you want achieve that, you might need set up NIS or LDAP to get same useraccounts to clients.

!users
13:40
<ltsp>
users: LTSP users for graphical login should be created on the server itself, NOT inside the client chroot. LTSP clients connect to the server to verify user credentials, they should not hold any user information themselves as this is very insecure.
13:42
<Hyperbyte>
But SSH'ing to clients should technically be possible if you set a root password. Why you'd want to do that is beyond me though. You should check /var/log/auth.log on the client.

21:40
<Hyperbyte>
kev_n, the arguments to the xrandr command. Depends on what you're trying to do
21:41
Let's say you type xrandr --output VGA1 --mode 800x600 to configure the display
21:42
You'd do XRANDR_OUTPUT_0=VGA1 XRANDR_MODE_0=800x600
21:53alkisg has joined IRC (alkisg!~alkisg@ubuntu/member/alkisg)
22:15
<kev_n>
ohh ok, thank you hyperbyte
22:16
does configure_x need to be set to true or does it matter?
22:17
<vagrantc>
configure_x shouldn't been deprecated ages ago...
22:17
or did we re-purpose it?
22:18
<kev_n>
dunno, but it is in the man file for lts.conf
22:18
<vagrantc>
sadly, the docs are usually only updated when someone notices something wrong with them
22:18
they haven't received a lot of work in quite some time
22:20
<kev_n>
really? I remember it looking different last I looked, like it had been updated/re-formatted recently (I'm on Debian wheezy rc/ltsp 5.4.2-5)
22:21
it seems a lot more comprehensive than last I looked too

<vagrantc>
last upload of ltsp-docs was in june of 2012...
22:22
<kev_n>
wow, wonder if it has been that long since I last looked...
22:22
or mebbe my memory is just that awful
22:22
so should I comment configure_x out/delete it?
22:23* vagrantc honestly can't remember if it's used anymore
22:23
<vagrantc>
kev_n: you can always comment it out and see what happns :)
22:25
<kev_n>
vagrantc: I guess that's true, I've been trying that for the most part, but I had just set it back and forth between true and false cuz I didn't actually think of commenting it out... not exactly my proudest moment
22:26
<alkisg>
CONFIGURE_X is supposed to be set automatically when a xorg.conf needs to be generated
22:27
In most cases it doesn't need to be present in lts.conf
22:27
<kev_n>
are the xrandr settings dependent on others? i.e. you need xrandr_output for xrandr_mode to work, or something like that?
22:27
<alkisg>
No
22:28
There's also XRANDR_COMMAND_0 to 9 if you want a simpler form
22:29
<kev_n>
I don't think I am using it correctly so I am trying to go back and forth using different options
22:30
<alkisg>
What do you want to do, and what's your current lts.conf like?
22:30
<kev_n>
here is what I had tried first || XRANDR_COMMAND_0="xrandr --newmode 1920x1080 124.4 1920 1952 2640 2672 1080 1102 1113 1135 -hsync +vsync" / XRANDR_COMMAND_1="xrandr --addmode DVI1 1920x1080" / XRANDR_COMMAND_2="xrandr --output DVI1 --mode 1920x1080 --output DVI2 --mode 1920x1080" ||
22:31
<alkisg>
It was cut in half, better use pastebin
22:31
<kev_n>
I just got a new thin client and have been trying to get dual screens working (it's a hp t5570)
22:31
<alkisg>
If you run those commands in a terminal, do they work like you want them to?
22:32
<kev_n>
I haven't been able to log in on the client.... ohhhh I just realized I didn't use update sshkeys
22:33
http://pastebin.com/m6PAHnpM
22:36
<alkisg>
Start with solving your login problems, so that you can test xrandr commands locally and not by rebooting a client each time
22:36
Also it's XRANDR_RATE_0 to 9...
22:37
<kev_n>
oh.. duh
22:37
thanks
22:42
so when I start it up it starts up at 640x480 at a 59 refresh rate, so it is all screwy, and I hit ctrl-alt-f1 to get into the terminal and try logging in but it won't let me despite setting the password in the chroot for root and user
22:43
obviously I am screwing up something, probably simple...
22:43
<alkisg>
Can't you login at the 640x480 ldm screen?
22:44
!screen_08
22:44
<ltsp>
screen_08: To get a root shell on a Debian thin client, put SCREEN_07=ldm, SCREEN_08=shell and SCREEN_DEFAULT=07 to lts.conf.
22:44
<alkisg>
Also this could help... ^
22:44
<kev_n>
I can, but I can't see it because the monitor doesn't like the resolution/refresh
22:44
ok, will try that
22:52
it says can't open display
22:52
do I need to add a --display or --screen option
22:53
<alkisg>
!xauthority

22:53
<alkisg>
Also put /var/log/Xorg.7.log to pastebin (you can scp it to your server first if it helps)
22:57
<kev_n>
I just get the > after hitting enter
22:58
is it mebbe export $(tr '\0' '\n') < /proc/$(pgrep -nx 'ldm|kdm_greet|lxdm-greeter-gt|dbus-daemon')/environ | egrep '^DISPLAY=|^XAUTHORITY='
22:58
?
23:00
that just seemed to make it freeze when I put the ) there
23:02
<alkisg>
You missed some of the quotes
23:03
<kev_n>
ok
23:03
<alkisg>
Hmmm wait
23:03
No it needs a final parenthesis

23:07
<kev_n>
and I am supposed to do this on the client, right? or not?
23:10
<alkisg>
On screen 08
23:10
<kev_n>
ok, thought so and just did... and use scp to copy it to the server?
23:10
<alkisg>
kev_n: if you run that, now you can try xrandr from the terminal
23:11
And see the available modes, test the 'xrandr --newmode' commands etc
23:12
Xorg.7.log might reveal that the driver can't read the display EDID so you might just need X_HORZSYNC and X_VERTREFRESH
23:12
<kev_n>
oh, ok, sorry, not overly familiar with this
