<alkisg>
stgraber: an idea about nbd swap: "prerun=nbdswapd %s", "virtstyle=ipliteral" and "exportname=/var/run/ltsp-swap/%s"
06:07
and another one: a one single swap file exported with "copyonwrite=true", "sparce_cow=true"
06:07
In both cases, NBD_SWAP=True would result in using the export named "swap".
06:08
I can try to implement one of the in the next couple of days - any preference on which?

<shan>
hello! I have installed ltsp-5 on my ubunut 10.04 server
09:54
I have dotmatrix printers connected to my nodes
09:54
I have put made the entries in lts.conf
09:55
but when I try to print form any applications it is not printing
09:55
but when I do a telnet 192.168.13.23 9100 and type something it is printing
09:55
any idea why?
09:58
could this be because of a wrong printer driver configuration?
10:42
Can some one help me. When I try to login from the terminals sometimes it does not login it.
10:42
It keeps showing the login screen
10:42
after a few tries it goes in.

<Hyperbyte>
shan, so you have two problems. One is that you can't always log in, and two is that the printer doesn't wor, correct?

12:09
<shan>
hyperbyte: sorry! i was away from my desk.
12:09
Yes as you said I have two issues
12:10
could you please tell me what is the difference between ltsp-server and ltsp-standalone-server?
12:10
these two are available in ubuntu
12:11
could there be any thing to do with this and the issues?
12:12
I have been using ltsp for almost 7 years now and haven't had such kind of problems
12:12
before
12:13
Hyberbyte: ???
12:15
<markit>
shan: I think the latter installs much more packages, like dhcp and tpftp
12:15
shan use "aptitude show packagename" to see the differences
12:16
i.e. I use dnsmasq for dhcp and tftp, so don't want a "mega-package" that installs things I will replace
12:16
<shan>
ok, but what I uninstalled the standalone and installed only there server and I find that it is installing pretty much most of what is required
12:17
so the stand alone is the mega?
12:17
<markit>
yes
12:20
<shan>
Some times when I try to login from the nodes, the login screen reapperas. Only after a couple of tries I am able to get to the desktop. Any clue as to why i could be having this problem?
12:20
<Hyperbyte>
Is there anything in /var/log/syslog on the server?
12:21
It can be a bit quiet in this channel during weekends by the way. ;-)
12:21
<shan>
I under stand
12:23
<Hyperbyte>
When the login screen disappears and reappears it usually means it couldn't open an SSH session for some reason
12:23
As for your printer problems, are you trying to print with an application running on the server or a localapp on the client?
12:24
<shan>
application running on the server.
12:25
It is a Java swing application
12:25
<Hyperbyte>
Then you don't need any of the options in lts.conf
12:25
You need to distinguish between client and server here. Anything that runs on the server, will use the server's configuration. Anything that runs on the client, will use the client's configuration.
12:25
<shan>
We have been using this for quite some time. Last week we have a hard disk crash and hence I had to reinstall.
12:26
<Hyperbyte>
lts.conf is used to set client configuration. If you want an application running on the server to be able to print, you just need to configure cups on the server.
12:26
Try visiting http://localhost:631/ using a browser running on the server.
12:26
<shan>
I have cups configured on the server, I have entries for the printers in the lts.conf file
12:27
<Hyperbyte>
You don't need entires for the printers in lts.conf, unless you are using "ltsp-localapps" to run the program.
12:27
<shan>
the java application will be run by the users on the clients, what I ment by server was that it is not a local app
12:27
<markit>
shan: that happend to me with older version of kubuntu, was a proxy problem
12:28
shan: or better, maybe I misunderstood your problem, I had to enter password 2-3 times sometime
12:28
<shan>
when I telnet 192.168.13.22 9100
12:28
<Hyperbyte>
shan, you just said two very conflicting things in one line. You said it's ran by users on the clients, but it's not a local app. If it's not a local app, it's running on the server. This is how LTSP works.
12:28
<markit>
btw, need to reboot, bye
12:28markit has left IRC (markit!~marco@88-149-177-66.staticnet.ngi.it, Remote host closed the connection)
12:29
<shan>
and type some text it gets printed to the printer
12:29
but when I try to print from the java application, it is not printing
12:30
<Hyperbyte>
Right, but where the actual user application running? On the LTSP thin client, using ltsp-localapps, or on the LTSP server?
12:30
<shan>
I need a clarification, when I click on the fire fox from the client is it a local app or server?
12:30
<Hyperbyte>
That depends. :)
12:31
Are you logged in to a client now?
12:32
<shan>
no, i can in a short while, i just removed the ltsp-standalone-server and am installing ltsp-server
12:32
can I get in touch with you once it is completed
12:34vagrantc has joined IRC (vagrantc!~vagrant@conference/debconf/x-sjaouxwczbvjuzex)
12:35
<Hyperbyte>
Okay
12:35
You are using thin clients right, not fat clients?
12:36
<shan>
yes, i am using pcs with out a hard disk with pxe rom
12:37
<Hyperbyte>
What's the command you use to build the client? Just ltsp-build-client, without any parameters?
12:37
<shan>
yes
12:37
<Hyperbyte>
Okay
12:37
Then, by default, anything you start on the client, runs on the server.
12:37
The client boots, starts a kernel, detects hardware and does some other Linux & LTSP magic...
12:37
And then it starts X and LDM (the LTSP login manager), also on the client.
12:38
<shan>
that's what I thought and the reason for the confusion as to whether it is running on server or local client machine
12:38
<Hyperbyte>
After you've entered your username and password and hit 'enter' it opens a connection to the server, and from that point on, -anything- that starts, is ran on the server and not on the client.
12:38
<shan>
ok
12:39
<Hyperbyte>
However, it is also possible to run programs on the client. If you have fast clients, it could be useful to run a webbrowser locally, for example, because it greatly saves your server.
12:39
<shan>
that was my understanding too. In the older versions of ltsp, we never used to have these clients builds and so on
12:39
ok, so how do I do that?
12:39
<Hyperbyte>
Now, if you would want to print with the webbrowser running on the client, you'd need to configure a printer on the client, which is what lts.conf is for.
12:40
<shan>
ok
12:40
<Hyperbyte>
So if your java app is started normally on the server, you don't need any configuration for it's printers in lts.conf
12:40
<shan>
ok
12:40
I got your point
12:41
<Hyperbyte>
So, your problem lies in the server configuration. Not in lts.conf and it probably isn't even LTSP related.
12:41
<shan>
since the printers are configured as hpjet printer, right?
12:41
<Hyperbyte>
Try logging in using keyboard and monitor on the server itself, you'll probably have the same problem with the java application.
12:42
<shan>
let me give it a sholt
12:42
shot
12:43
I will have to wait for the ltsp-build to be overs and the printers are connected to the clients
12:43
<Hyperbyte>
Wait - the printer is connected to the client?
12:44
I thought they were network printers?
12:44
14:28 <shan> when I telnet 192.168.13.22 9100
12:45
<shan>
no, they are dot matrix printers connected to the clients and that is why I was using lts.conf
12:45
<Hyperbyte>
Right - well that changes things.
12:45
<shan>
:)
12:45
<Hyperbyte>
In that case, yeah, you're gonna need lts.conf
12:45
But you're also gonna need to run the java application on the client.
12:45
Not on the server.
12:46
This is done with the command 'ltsp-localapps'
12:46
For example, 'ltsp-localapps xterm' will give you a terminal on the client.
12:47
<shan>
but in my previous installation, we never did it that way.
12:47
<Hyperbyte>
Are you 100% sure?
12:48
I could be confused about how this works then, I'm no LTSP expert. But I thought printers on client and server are seperated.
12:48
<shan>
The users will have a shortcut to the application on their desktop and when they click it, it will execute a script /usr/java/jdk.../bin/java -jar xxx.jar
12:48
we have been using it this way for almost 6 to 7 years.
12:48
<Hyperbyte>
Are you sure the old shortcut didn't have 'ltsp-localapps' in it?
12:48
<shan>
I thought the new version of ltsp had some changes, if not then it should work.
12:49
I am dead sure.
12:49
<Hyperbyte>
Still, an LTSP from 6 to 7 years ago?
12:49
I bet some things have changed drastically, yes. :)
12:50
<shan>
a lot has changed and we had upgraded to ltsp-5 about 6 months to a year back if my memory serves right
12:50
<Hyperbyte>
Ahh
12:50
<shan>
and we didn't have any problems then
12:51
i had used almost all version of ltsp right from may be 2..
12:51
<vagrantc>
ltsp-localapps isn't all that old
12:51
so it sounds like something customized
12:51
<shan>
earlier we had to do some configuration to have application run as local apps and we never did that
12:51
<Hyperbyte>
vagrantc, am I correct when I assume that printers configured on the client are not available to apps running on the server?
12:52
<vagrantc>
Hyperbyte: not necessarily ... cups does tend to share things
12:52
<Hyperbyte>
mmm
12:53
<shan>
vagrantc, we have never used local apps earlier and neither are we using it now.
12:53
Hyperbyte was suggesting that we use local apps for better performance if the clients are fast and it would reduce the load on the server.
12:53* vagrantc was mostly skimming and saw Hyperbyte mention localapps and shan mention 6-7 years old ltsp
12:53
<Hyperbyte>
I wasn't suggesting it, I was explaining the difference between localapps and non-localapps. :)
12:54
<shan>
ok ;)
12:54
<Hyperbyte>
These printers are connected via paralel port I assume?
12:54
<shan>
yes
12:55
<Hyperbyte>
14:28 <shan> when I telnet 192.168.13.22 9100
12:55
How does that work?
12:55
<shan>
what ever you type on the terminal will get printed on your printer.
12:55
when you hit an enter key it will give a line feed.
12:56
this was how we test to see if the printer is indeed connected to the server through the client machine.
12:56
<Hyperbyte>
Well, that much I get. But if they're connected via parallel port, how do they have an IP address with a jetdirect port open?
12:57
<shan>
I am not aware as to how ltsp does that, i know only to use it that way.
12:58
<Hyperbyte>
LTSP does that? :o
12:58
<shan>
i really dont know the technical details.
12:58
<Hyperbyte>
Me neither. =D
12:58
<shan>
i am sure some one in this channel will be able to throw some light on that..
12:59
<Hyperbyte>
vagrantc probably can.
13:00
<shan>
I guess each one of the thin clients would act like a jet direct port when we configure it in lts.conf
13:00
so any information coming to the 9100 port is given to the printer..
13:00LoveStor- is now known as LoveStorm
13:02
<Hyperbyte>
Are the printers only used on the client they're attached to, or are they used on other clients as well?
13:03
<vagrantc>
the thin client essentially emulates an hp jetdirect printer by using jetpipe to connect to the network
13:03
<Hyperbyte>
That's cool! Never knew that. :)
13:03
<shan>
they could be used by the other clients too...
13:05
<vagrantc>
probably
13:05* Hyperbyte is learning here :)
13:06
<shan>
it sure is and I have always found this to be the place to get solutions for almost all of your ltsp problems, if they are not document too..
13:06
the people here are great, they come out and help when needed.
13:07
<Hyperbyte>
Yeah. :) I could've never gotten where I am today with LTSP without this channel. :)
13:07
<shan>
just to give you an update, we feel that there might be a problem with the os and the java program and may not be an issue with ltsp..
13:07
<Hyperbyte>
Anyway, if the clients act as jetdirect, then can't you just configure CUPS with the printers and be done?
13:08
<shan>
no, you will have to make entries in lts.conf to make it emmulate a jet direct device.
13:08
<Hyperbyte>
Yeah, of course, but after you've done that, can't you configure them in CUPS on the server?
13:09
<shan>
that is how we do it.
13:09
in the host name we would give the ip of the client machine with port as 9100
13:09
<Hyperbyte>
Do they work if you just print from a notepad application, rather than your java app?
13:10
<shan>
yes, it does, that is how we are narrowing down to the java app and the os and not ltsp..
13:11
<Hyperbyte>
:)
13:11
Well, hope I've at least been to some help. :P Hehe, I try, but don't know all there is to know about LTSP yet. :)
13:12
<shan>
me too. you sure have.. by they way which part of the world are you located?
13:12
I am in India
13:12
<Hyperbyte>
Netherlands. :)
13:12
<shan>
great, this make the world really flat
13:12
<Hyperbyte>
Hehe
13:13
<shan>
its like we are all in the same town.
13:13
<Hyperbyte>
LTSP town. :)
13:13
<shan>
true.
13:13
ok, thanks for the support, the ltsp server installation is still going on, Shall catch you later.
13:13
bye
13:14
<Hyperbyte>
Byebye
13:28
<shan>
vagrantc: I have an issue with my display on the server. As long as no clients are on, very thing goes fine. but the moment some one tries to log in, my screen gets a lot of lines and then becomes unusable. When I press ctrl+alt+f7 or f6 and then F8 it comes back to normal but only for a short time.
13:29
what could be the problem?
13:38
<vagrantc>
no idea
13:38
logging in with the same username?
13:40
typically, you should only log in to a single server with a given username once. it triggers bugs in *many* applications that make bad assumptions.
13:44
<Hyperbyte>
*cough* Firefox *cough*
13:45
<shan>
no, I am logged in to the server, where as some other user is logging into through the client
13:49
when I log out the log in screen says mode not supported, how could I change the resolution of the log in screen?
13:50
I need to use 1024 x 768 but by default it is set to some thing higher
