<vsuojanen>
vagrantc: Hi
17:06
ltspfs did the mount job with localdev when i used xfreerdp
17:06
<vagrantc>
sure
17:08
<vsuojanen>
one more thing is with network level authentication. you need to give the userid, passwd and server there in xfreerdp options
17:08
xfreerdp --from-stdin -f --plugin rdpsnd --plugin rdpdr --data disk:Drives:/media/root -- server
17:09
and that was not useful with xinitrc
17:10
i worked it like this
17:10
xfreerdp --from-stdin -f --plugin rdpsnd --plugin rdpdr --data disk:Drives:/media/root -- server
17:10
aa
17:10
SCREEN_07 = "xterm -geometry 120x24+100+100 +sb -title 'RDPClient' -e /bin/bash -c 'xfreerdp --from-stdin -f --plugin rdpsnd --plugin rdpdr --data disk:Drives:/media/root -- serve¨r
17:12
with network level authentication it doesn't start the rdp session before the authentication is done ?

17:43alkisg has joined IRC (alkisg!~alkisg@ubuntu/member/alkisg)
17:48
<vagrantc>
haven't really used the rdp support much; i suspect it depends on how your environment is configured.
17:48
the ltsp scripts don't do anything other than what you tell them
17:49
there's not really much that is LTSP specific in the rdp support in those scripts
17:52
ltsp does no authentication on it's own with the xfreerdp screen script.
17:52
it simply calls xfreerdp
17:52
there is some rdp support in LDM which does handle some of the authentication... i've only briefly tested that.
17:55
vsuojanen: the RDP server i used presented a login screen over RDP, so xfreerdp didn't need to bother with that.
18:05
<alkisg>
xfreerdp -u ''
18:05
That presents a login screen
18:06
And I think we managed to work around "--" in xinitrc, so it shouldn't be an issue...
18:07
RDP_OPTIONS=${RDP_OPTIONS:-"-f -u ''"}
18:07
The user is expected to add those to his command line, if he's using SCREEN_07="xfreerdp params"
18:09
<vagrantc>
aha
18:10
inklings of a memory about that were starting to seep in, but of course, alkisg beat me to it!
18:11
<alkisg>
inklings, never heard of that one before! :)
18:12
Google translate didn't have that one, fortunately http://www.merriam-webster.com/dictionary/inkling did
18:23
<vagrantc>
heh
18:23
alkisg: gotta be something i can tech you yet :)
18:33
<vsuojanen>
thank u
18:35
i tested '' and ' ' but i couldn't get it working.
18:38
alkisg: so i should get rpd session login prompt.from win7 when i give xfreerdp -u '' ? it makes no difference if nla is on or off?
18:39Dsys has joined IRC (Dsys!466ada6e@gateway/web/freenode/ip.70.106.218.110)
18:42
<vsuojanen>
i think it xfreerdp doesn't give the login prompt from remote desktop service if nla is "forced" there in server
18:42
<alkisg>
vsuojanen: put SCREEN_07=xterm and start the tests there
18:43
When you find the correct params, then put them in lts.conf
18:43
xfreerdp -f -u '' in my experience gives a login prompt, at least in w2008 server
18:43
<Dsys>
Good afternoon. Would anyone happen to know if LTSP fat clients always require ssh access to the server? I'm concerned that the users will be able to ssh into the server to run cmds/store data when I don't want that. I could try to configure LTSP to use ldap auth/NFSHOME, but I wasn't sure if some amount of ssh access would still be required.
18:44
<alkisg>
Dsys: are there other services on your server and you don't want your users to have ssh access to it?
18:45
E.g. suppose you used a VM server or a chrooted server, would that help/
18:45
?
18:46
...and, you don't want them to store data? what about /home/username, not even there?
18:46
<Dsys>
Nope. Not even there. I have it configured to mount an overflayfs over their NFSHOME (which is exported as ro)
18:47
<vsuojanen>
alkisg:
18:47
20:10 < vsuojanen> SCREEN_07 = "xterm -geometry 120x24+100+100 +sb -title 'RDPClient' -e /bin/bash -c 'xfreerdp --from-stdin -f --plugin rdpsnd --plugin rdpdr --data disk:Drives:/media/root -- serve¤r
18:47
<Dsys>
A chrooted server could work, but I cant find much online about what I need to put in that chroot. (I see it tries to call echo and exec on the LTSP server when I log in from a client)
18:47
The idea is I don't trust my users and dont want them to be able to store data or mess with my server, yes.
18:50
I had attempted to set the shell to 'lshell' but no amount of configuration seems to allow LTSP to fully login and do what it needs to (for the record, lshell's logs show that it seems to get hungup on some escape sequence, even though I had allowed the use of ';' for the "echo LTSPROCKS; /bin/sh -" that LTSP calls.
18:58
<vagrantc>
Dsys: do the users need to be authenticated?
18:58
Dsys: you could use the kiosk scripts or something like that
18:59
<Dsys>
kiosk scripts? I hadnt read about that. I'll check into those.
19:00
<vagrantc>
SCREEN_07=kiosk
19:00
typically used for just a web browser kiosk, but there's no technical reason you couldn't run a whole desktop session ...
19:01
or, if there is a technical reason, we should fix it :)
19:02
<Dsys>
I pretty much just want to launch Remmina (as a vnc client)
19:03
and have that utilize the client hardware's resources, as they are fat clients. It sounds like kiosk mode only works for thin clients...or do you know if thats not the case?
19:03
<vagrantc>
we should probably write a vnc screen script or something
19:03
shouldn't be too hard to adapt one of the other scripts to cal remmina
19:03
kiosk mode runs on the local hardware
19:04
but "just want to launch remmina" doesn't wouldn't be much of a fat client .... ?
19:04
<alkisg>
vsuojanen: that allows you to give the password via stdin, not in the server login screen though, right?
19:04
<Dsys>
it's not much of a fat client, but the ltsp server isn't beefy.
19:05
<vagrantc>
sure
19:05
it shouldn't be hard to write a screen script that calls remmina
19:05
<alkisg>
Dsys: where are you vnc'ing to? a windows server, a linux server?
19:06
<Dsys>
Windows yes
19:06
<alkisg>
It's strange that you're using vnc, it's the lamest of all the remote desktop protocols... :)
19:06
Why not use xfreerdp to connect to windows?
19:06
LTSP already has a script for that...
19:06
<Dsys>
yep, that wasnt my choice.
19:07
it has to be vnc, sadly.
19:07
that part is not up to me.
19:07
<alkisg>
OK
19:07
It's not fat clients if you vnc though
19:07
<Dsys>
but im not sure how this affects user login?
19:08
<alkisg>
How are you providing the windows credentials for vnc?
19:08
<vagrantc>
you don't even need a user to log in from the LTSP client perspective, it can just run your VNC client
19:08
<alkisg>
try this: SCREEN_07=xterm
19:08
...and from that xterm, try to launch vnc with the params you want
19:09
If the result satisfies you, you can easily put that in lts.conf
19:11
<Dsys>
ok i think i see where you are going with that.

alkisg: might be worth writing a generic xinitrc screen script wrapper to call arbitrary commands ...
19:15
rather than having the xterm lingering in the background
19:16stgraber has left IRC (stgraber!~stgraber@ubuntu/member/stgraber, Ping timeout: 276 seconds)
19:17
<alkisg>
It can even replace the xfreerdp, the xterm and other scripts, I didn't like the RDP_OPTIONS and RDP_SERVER split anyway, they can't be used in multiple screens...
19:19
<vagrantc>
why didn't we think of it sooner? :)
19:25
<alkisg>
I think there were security concerns

<Dsys>
Thanks :) I am able to load xterm with SCREEN_07=xterm, and it will call remmina when I issue that command. Is there a way to have it launch with remmina? I can deal with the ugly xterm window in the background if needed. I tried copying the xterm script in the screen.d folder to "xterm-vnc" with the idea i could feed it the args needed to run remmina. For now, i did not modify it so it should just launch xterm again. But when I then c
19:33
SCREEN_07=xterm-vnc , it appears to hang during boot. Note again that I did not modify the contents of the xterm script yet, it is merely a copy of xterm.
19:33
<alkisg>
SCREEN_07="xterm -fullscreen -e vnc" etc etc
19:34
man xterm for details

<alkisg>
Try it first from withing the xterm window
19:34
To find out the params before you use lts.conf
19:34
<Dsys>
ahh ok
19:35
very cool. i will give that a shot. for now I just jet. Thanks again for the suggestion.
19:35
<alkisg>
You're welcome
19:36
<vagrantc>
can't just call remmina directly?
19:38
<alkisg>
xterm -e whatever, sure... is remmina a better vnc client?
19:38
Or is it just a wrapper?
19:40telex has left IRC (telex!teletype@freeshell.de, Remote host closed the connection)

remmina supports arbitrary backends, i think vnc, rdp, ssh -X, etc.
