I recall people talking about running voip client software from thin clients. Are people doing this?

Political campaigns need to setup phone banks. It would be very cool if LTSP and Asterisk could provide this at people's homes throughout the country. Phone banks of 20-30 people.
10:24

joebaker: I've done it kinda
10:33Sly-Guy has joined #ltsp

joebaker: There was an article on Linux Jorunal some time ago about this.
10:39
<joebaker>
rjune Nice.
10:39
sbalneav: I seem to recall that.
10:40
<rjune_>
joebaker: not really, it didn't interop with anything but itself.
10:40
still, it was a start
10:40
<joebaker>
yes. You had voip clients running on the thin clients. Were they local apps or using pulse audio?
10:41
or both?
10:41muh2000 has joined #ltsp
10:41
<sbalneav>
The article did it with local apps.
10:41
<joebaker>
thanks I'll go dig it up at linuxjournal.com
10:42
I suppose it could work now with server side apps piping through pulseaudio.

Here's my google query to locate the article: http://www.google.com/search?q=voip+ltsp+site%3Alinuxjournal.com&ie=utf-8&oe=utf-8&aq=t&rls=com.ubuntu:en-US:official&client=firefox-a
10:49
<rjune_>
local apps
10:49
any reason to do it any other way?
10:51cliebow__ has quit IRC
10:51
<sbalneav>
Well, seeing as how localapps really doesn't work without a whole lot of manual effort, getting to go via pulse would be a nice solution.
10:52
But I'm bending my 2-3 braincells towards localapps right now.

Quick question to everyone: I'm debating doing an Edubuntu LTSP install at home for my kids and wife's computers. Just wondering what is the recommended hardware would be to do this and if there is any good page that may have the pros/cons for this setup.
11:03
Recommended hardware for the client machines that is.
11:07
<sbalneav>
Check out the Edubuntu handbook
11:07
!handbook
11:07
<ltspbot`>
sbalneav: "handbook" is The edubuntu handbook is the best source of LTSP5 documentation. You can find it at: http://doc.ubuntu.com/edubuntu/handbook/C/
11:08
<sbalneav>
There's a sizing section, some hardware recommendations, and other info.

sbalneav, i am not able to log in to any server, except one, ldm just respawns as soon as i enter password, here is the ldm.log http://pastebin.ca/718580
11:24
<sbalneav>
Connection to 10.0.0.2 closed by remote host
11:24
<cyberorg>
failsafe login and login using the same image into the server the other(working) server works fine
11:25
<sbalneav>
Something's terminating the the connection.
11:25
<cyberorg>
sbalneav, where do i look?
11:25
<sbalneav>
take a look in the .xsession-errors file.
11:25
<cyberorg>
after failsafe login, i can launch Xsession fine
11:26
where do i find .xsession-errors?
11:26
<sbalneav>
in the home directory of the user
11:27
<cyberorg>
there is no such file on server ~/
11:28
<sbalneav>
Well, then maybe the user has problems with their home dir.
11:29
should be right in /home/user/.xsession-errors
11:29
<cyberorg>
sbalneav, i tried on three different servers fresh installed
11:30
<sbalneav>
Are you already logged in as one of the users somewhere?
11:30
i.e. are you trying to log in muliple times?
11:30
<cyberorg>
sbalneav, nope, server is on init 3
11:31
<sbalneav>
You're running gutsy?
11:31
<cyberorg>
sbalneav, hold on, got xsession-error, suse :)
11:32
<sbalneav>
ah.
11:32
<cyberorg>
http://pastebin.ca/718652
11:32
there
11:32
<sbalneav>
Ah, right, you're one of the suse devels
11:33
<cyberorg>
not suse devel, kiwi-ltsp devel ;)
11:33
<evarlast>
joebaker: Ron Paul? who is that? ;)
11:33
<cyberorg>
sabayon fsked?
11:33
<sbalneav>
yeah
11:33
looks like sabayon's doing you dirt
11:33
if sabayon returns an exit code of 1, it'll kill your session.
11:33
<cyberorg>
sbalneav, user can login on from the server fine
11:35jimcooncat has joined #ltsp
11:35
<cyberorg>
can sabayon be safely removed?
11:36
<sbalneav>
Ummm, well
11:36
how I'd suggest to fix it is:
11:36
take a look where the sabayon's being invoked:
11:37
it's probably doing a "sabayon-apply"
11:37
change it to sabayon-apply || true
11:37
<cyberorg>
hope it is not in gnome-session
11:40
sbalneav, did some more testing, .xsession-error is not generated when login in from ltsp client, only when login from the server
11:40
<jimcooncat>
what is the favorite method for deploying remote access to home users? freenx? putty/vnc? something else?
11:41
<sbalneav>
cyberorg: Wierd. However, it's probably the sabayon that's mucking you up.
11:42mpthx has quit IRC
11:42
<cyberorg>
sbalneav, i removed sabayon
11:43
<sbalneav>
ah, ok
11:43
That fix it?
11:44
<cyberorg>
nope, still same
11:44
logs out immediately, can login failsafe
11:44
<sbalneav>
Hmm.
11:44
Well, something's bunging up the works.
11:44
<cyberorg>
any other logs i can check?
11:45
<sbalneav>
Well, .xsession-errors the place where it SHOULD log
11:46
so, the fact that it isn't on a thin client is.... troubling.
11:46
It does on Ubuntu, but that doesn't help you much.
11:47
<cyberorg>
i have .xsession-errors only when i log on directly on the server
11:47
here is the latest one http://pastebin.ca/718668
11:47
<sbalneav>
things are settling down a bit now with the Ubuntu release, i'll spend some time and get opensuse/kiwi going this weekend.
11:47
yeah, it should log to .xsession-errors regardless.
11:47
<cyberorg>
cool :)
11:47
<sbalneav>
So there's a bug somewhere.
11:48
<cyberorg>
ldm.log doesn't show ssh command anymore
11:48
<sbalneav>
hm
11:48
weird.
11:48
<cyberorg>
earlier it used to show ssh -X bla bla
11:48
this is the latest code from gutsy-ltsp
11:49
however, i know ldm is fine as i can log into another server, am not able to log on to any fresh installed openSUSE RC1 servers
11:51
i get just one line in /var/log/messages "Accepted keyboard-interactive/pam for geeko from 10.0.0.100 port 54059 ssh2"

11:58
<Sly-Guy>
sbalneav: Thanks for the info.
11:58
<evarlast>
its easy to deploy putty regular, just extract the registry keys
11:58ogra has joined #ltsp
11:59
<jimcooncat>
haven't used winders in so long, can I just give my users a .reg file?
11:59
<evarlast>
jimcooncat: yes
12:00Sly-Guy has quit IRC
12:01
<jimcooncat>
wow, that sounds really secure -- not! Anyway if it works for my purposes then great.
12:05
<evarlast>
what?
12:06
how is it insecure?
12:07
<ogra>
evarlast, how secure would you find it if all your users could just replace /etc ?
12:07
<evarlast>
not the same.
12:07
read up on how windows actually works.
12:08
all my users CAN just replace /home/<username>
12:09
<jimcooncat>
evarlast: I didn't mean distributing a .ref file was insecure -- it's that a user can run it without giving it some authorization is kind of iffy.
12:09
.reg file i meant
12:10
<evarlast>
so you are just complaining about explorer.exe's default behavior for .reg files? Turn that off :)
12:11
<jimcooncat>
mine will be the last .reg file they double-click! bwu-ha-ha-ha
12:11
<evarlast>
nice. I like it!
12:11
<lns>
AFAIK there are registry permissions just like the filesystem that depend on the users' rights..they can't just go and blow an install with a .reg file
12:11
<evarlast>
i wonder if you could make a .reg file that disables the .reg file associations. So you double click the .reg file and then you can't click them again.
12:12
lns: right, that was kinda my point and why I asked "insecure what?"
12:12
<lns>
of course, most people run with admin rights, right? =p
12:14Daggett has quit IRC
12:15
<evarlast>
not me :)
12:16
<lns>
well i would hope most people in #ltsp wouldn't be.. ;) of course they wouldn't be using windows in the first place... ? ;)
12:16
<evarlast>
yeah, sorry. I'm a windows guy.
12:17
I rock both worlds instead of just one.
12:17
<jimcooncat>
just read a "trouble-shooting" article on Ubuntu Wiki suggesting replacing LTSP's ssh/ldm combo with openvpn/xdmcp/gdm. Any thoughts on that?
12:17
<lns>
here's a question - has anyone deployed FreeNX on Ubuntu/LTSP5?
12:17
<ogra>
lns, not unless the code changed massively
12:18
freenx ships a complete copy of the x libs ... that way it will never enter ubuntu
12:18
<lns>
ogra, oh wow
12:18
that's really too bad
12:18
<ogra>
nomachine was talking to us several times making big promises over the last years
12:18
but never changed a line
12:19
<lns>
I'm having problems deploying a windows client for the teachers of my school labs to get into an X session without having to have a thin-client at their desks too
12:19
i was thinking NX but if that's the case....
12:19
<ogra>
so unless someone starts to port it over to work with the stadard libs it wont get in
12:19
<evarlast>
jimcooncat: how about ipsec instead of openvpn or ssh !
12:19
<ogra>
lns, nx is fine function wise
12:19
<jimcooncat>
freenx would have been great if they hadn't bundled up so much -- they didn't need to provide ssh, for instance
12:19
<ogra>
you just dont get any security support or anything
12:20
<lns>
ah
12:20
<ogra>
yeah, ssh is in there as well
12:20
<sepski>
lns, you must either install freenx from custom repos. or if all they need i 1 or 2 applications you can use putty+xming on the windows
12:20
<ogra>
i think it gets near a rewrite to fix these
12:21
<lns>
I'd rather use VNC since it's so "universal", but I need two things - 1) for it to work at the GDM level, and 2) for it not to require using XInetd... I'm sure i can figure out getting it going under regular inetd, its a matter of translating the config files...i just read the only howto on VNC/GDM and it called for xinetd..which i stupidly installed and messed up LTSP in the process
12:22
it'd be so nice just to have VNC default to running under GDM instead of an already-logged-in user session...
12:23
<jimcooncat>
lns, big problem I had with freenx is that the server and client's versions must match -- most of the freenx packages are older, and it's harder to find matching clients for windows
12:23
<lns>
jimcooncat, i remember having that issue when first setting it up in my testlab last year
12:24
I also heard that VNC over SSH is comparable to NX in terms of bandwidth compression though..?
12:24
of course you don't get the caching benefits
12:26vagrantc has joined #ltsp
12:27
<jimcooncat>
lns, freenx is more responsive, and the network traffic is close. I had problems with the initial connections, though, and that was just over my home LAN
12:27
<lns>
vagrantc!
12:28
<sepski>
nx is amazingly good, i used NX from cyprus on a phone modem 56k to a machine in norway and i could almost play flashgames, working on the machine was no problem
12:28
<jimcooncat>
lns, they use very different methods (usually) to communicate
12:28
<lns>
Wouldn't it be cool to fork NX to run via thin clients... ;)
12:29
<sepski>
lns, you can also add a preconfigured web applet. that way you can provide a site like http://nx.domain.com, user enter username and password and they get a X desktop
12:29
needs java tho
12:29
<lns>
sepski, there ya go
12:29
<jimcooncat>
lns, thinstation does that

vagrantc, I just made a script for the amixer headphone-jack-sense fix...hoping the following line will work when I go down and test a client:
12:31
amixer set 'Headphone Jack Sense',0 on
12:31
<vagrantc>
lns: ah, cool.
12:31
<lns>
i got that from pastebin google cache... no idea if the syntax is correct and/or universal
12:31
<vagrantc>
lns: maybe i can use that.
12:32
<lns>
i'll letcha know if it ens up working
12:32
<vagrantc>
maybe i'll test it first :)
12:32
<lns>
haha, ok
12:32
that assumes that the sound card you're modifying is card 0
12:34
<vagrantc>
well, that's a reasonable assumption
12:34
in the case of a thin-client

<vagrantc>
lns: sure :)
18:24
lns: i still haven't tried it yet ...
18:25
<lns>
vagrantc, as long as alsa *detects* the headphone-jack-sense (and you can manually switch it on and off w/alsamixer), it should work.
18:26
What's weird is that Edgy had it turned on by default (and stayed that way through upgrade to Feisty) but a new Feisty install defaulted to off.
18:26
Same hardware
