| |
03:30 | ==> That means that you can set "KIOSK_OPTIONS" in lts.conf to point to a specific web page

06:23 | <mgariepy> good morning everyone
| |
06:23 | <franck> good morning
| |
06:24 | I have a question for anyone witch can answer it :
| |
06:25 | do someone know how to setup a scanner plugged un an ltsp 5 client
| |
06:25 | ?
| |
06:26 | <mgariepy> have your tried the SCANNER=True in lts.conf ?
| |
06:27 | <franck> yes I did
| |
06:27 | still not working
| |
06:27 | just info : the scanner works perfectly when plugged on the server
| |
06:28 | <mgariepy> you need to have saned running on the client
| |
06:28 | installed on the thin client chroot.
| |
06:28 | <franck> ok
| |
06:30 | <mgariepy> it's part of sane-utils package
| |
06:30 | on ubuntu
| |
06:31 | <franck> ok apt tells me it is already installed
| |
06:33 | <mgariepy> in your session do you have SANE_NET_HOSTS variable ?
| |
06:33 | open a terminal and run: env | grep SANE
| |
06:35 | <franck> not seems to be set
| |
06:35 | your command returns me nothing
| |
06:35 | <mgariepy> which os version are you using ?
| |
06:36 | <franck> debian "squeeze" 6.0
| |
06:40 | <mgariepy> hmm, i'm out of idea.
| |
06:41 | the variable is supposed to be set in the user session
| |
06:41 | can you paste your lts.conf file on pastebin ?
| |
06:43 | <franck> Work in progres ...
| |
06:43 | <mgariepy> does saned running on the thin client ?
| |
06:44 | <franck> I don't know
| |
06:44 | Gremble has quit IRC | |
06:44 | <mgariepy> you can run: ltsp-localapps xterm
| |
06:45 | this will open up a shell on the thin client
| |
06:45 | <franck> wait wait wait, I found a tutorial at the end of the web, I think I'll thy it it seems to be nice
| |
06:45 | <mgariepy> ok

09:37 | <jtwood> Hello everyone.
| |
09:38 | Just had a question about using some of the advanced build options, specifically caching and using that cache for future client builds. I am not sure that I completely understand and know how to set this up. There also doesn't seem to be much documentation that I have found on this.
| |
09:54 | <Gadi> jtwood: I believe if you pass ltsp-build-client the option "--mount-package-cache", it will bind-mount the server's apt archive cache into the chroot
| |
09:54 | that way, all of the packages that the chroot downloads the first time can be available on subsequent times
| |
09:54 | if you do not want to share the server and chroot package archives, you can specify a different server directory to use
| |
09:55 | with: --mount-package-dir <directory>
| |
09:57 | wakko222 has joined #ltsp | |
10:00 | <wakko222> jtwood: thanks for the help the other day. My LTSP setup worked great with your help. Booting from Grub is really simple too.
| |
10:18 | <jtwood> Gadi: okay...I've done that. It just seemed that it isn't actually pulling the packages from the cache. I'll play around and watch what its doing on the next build.
| |
10:20 | I am sure its something simple. It seems that the packages are being cached. One other question, is much of these documented other than the basics?
| |
10:24 | Kicer86 has quit IRC | |
10:26 | <bieb> Gadi: quick question for you.. my boss and the network admin redesigned out network last night.. changed the way we had subnetting etc. I reset the IP on my ltsp server, and the clients get the boot screen. but authentication does not work. We have AD and I am using likewise-open. I have disconnected and reconnected to the domain, with no luck. Do I have to update the ltsp image for the ip changes??
| |
10:27 | jhutchins_lt has joined #ltsp | |
10:29 | <Gadi> bieb: sudo ltsp-update-sshkeys && sudo ltsp-update-image
| |
10:29 | <bieb> Gadi: so that is the thing I am missing huh?
| |
10:30 | <Gadi> jtwood: ltsp-build-client "plugins" are distro-specific, which is why you can get options with: ltsp-build-client --extra-help and not in the man page
| |
10:30 | if there were docs, i would look toward the distro wiki
| |
10:32 | <jtwood> I kind of figured that...no biggie...thanks for direction though

11:05 | <bieb> Gadi: you still around?
| |
11:05 | <Gadi> corporeally
| |
11:07 | <bieb> ok.. after doing ltsp-update-sshkeys && ltsp-update-image ( iwas already sudo) when I boot one of the clients it fails to load
| |
11:07 | <Gadi> fails to load how?
| |
11:07 | <bieb> Mount: mounting /dev/nbd0 on /rofs failed:invalid argument
| |
11:07 | <Gadi> you mean it does not boot all the way?
| |
11:07 | ah
| |
11:07 | do you have more than one image?
| |
11:07 | <bieb> right doesnt complete
| |
11:08 | should only be one image
| |
11:08 | <Gadi> try: ltsp-update-image --force
| |
11:08 | <bieb> the next failed mounting are /dev /sys /proc
| |
11:08 | <Gadi> seems for some reason, your nbd port numbers got screwed up
| |
11:08 | (you are oon Ubuntu, correct?)
| |
11:08 | <bieb> then tells me target filesystem doesnt have /sbin/init
| |
11:09 | yeah ubuntu
| |
11:09 | <Gadi> ok
| |
11:09 | try: ltsp-update-image --force
| |
11:09 | <bieb> ok
| |
11:09 | <Gadi> that will force it to recalculate the port numbers
| |
11:09 | and hopefully set you straight
| |
11:09 | <bieb> sounds good..
| |
11:09 | will let you know
| |
11:17 | Gadi: when I run the update image.. there is no force option.. if I run it regular at the end I get 2 "Info" notes....
| |
11:18 | first.. Port 2000 is already defined with /opt/ltsp/images/i386.img in inetd.conf
| |
11:18 | second.. taking no action

11:29 | <Gadi> bieb: you did "--force"?
| |
11:30 | two dashes?
| |
11:30 | maybe ur on an older version
| |
11:30 | well then, you will have to make some hand edits
| |
11:30 | check: /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default
| |
11:31 | make sure nbdport=2000
| |
11:31 | on the kernel command line
| |
11:42 | <bieb> yeah I did --force. I do have an older version... 9.04
| |
11:42 | options are: base, port, no-comp,exclude-dirs,tftpbootdir,arch, and help
| |
11:44 | <Gadi> ah
| |
11:46 | <bieb> so my next step is the /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default??
| |
11:51 | <Gadi> yeah: the port that the image is exported on (listed in /etc/inetd.conf) should match the port that the thin client is told to use (/var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default <- or 2000 by default)
| |
11:51 | <bieb> ok.. I will check there

11:54 | cliebow has quit IRC | |
11:59 | <bieb> Gadi: ok the /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default has just one line in it.. where should I add the ndbport?
| |
11:59 | DEFAULT vmlinuz ro initrd=initrd.img quiet splash
| |
12:04 | <Gadi> on that line
| |
12:04 | after squash
| |
12:04 | put nbdport=2000

| |
12:21 | <Gadi> correct
| |
12:21 | make sure the server is listening on port 2000 -> sudo netstat -anp|grep :2000
| |
12:26 | <bieb> yep.. listening

12:33 | <bieb> Gadi: what should I check next??

| |
12:35 | anything change in your image since last time?
| |
12:35 | <bieb> I know.. its driving me crazy.. hate when they break things on Friday
| |
12:36 | <Gadi> anything in syslog?
| |
12:36 | does syslog report that it is exporting i386.img?
| |
12:36 | <bieb> nope.. well except I chrooted in and created a small text file in /tmp, just to give it a change
| |
12:37 | havent checked syslog.. what should I be looking for?
| |
12:37 | <_UsUrPeR_> Gadi: about the rdesktop nosound issue I was having yesterday. I am still trying to figure it out.
| |
12:37 | spectra has quit IRC | |
12:37 | <_UsUrPeR_> lFor the record, sound works from rdp to windows. just not rdesktop in ubuntu.
| |
12:39 | <Gadi> bieb: also make sure your dhcpd.conf file is correct and it is handing out the right IP
| |
12:39 | _UsUrPeR_: what have you tried?
| |
12:40 | <bieb> ok
| |
12:40 | <_UsUrPeR_> gadi: rdesktop, remote desktop viewer, tsclient. rdesktop is the hopeful since I can put it in the lts.conf easily.
| |
12:41 | <Gadi> _UsUrPeR_: you are straying off course
| |
12:41 | :)
| |
12:41 | _UsUrPeR_: ok, first things first - can you get a shell on the client?
| |
12:41 | (or ssh in)
| |
12:41 | <_UsUrPeR_> yes
| |
12:41 | <Gadi> ok
| |
12:42 | can you run alsamixer?
| |
12:42 | spectra has joined #ltsp | |
12:42 | <_UsUrPeR_> yep
| |
12:42 | <Gadi> good levels, nothing muted?
| |
12:42 | <_UsUrPeR_> gadi: that is correct.
| |
12:43 | <Gadi> ok, is pulseaudio running?
| |
12:43 | komunista has quit IRC | |
12:45 | <_UsUrPeR_> ps aux |grep pulse shows it's running yes
| |
12:45 | /usr/bin/pulseaudio
| |
12:46 | <Gadi> and if you kill it and log into rdesktop, does sound work?
| |
12:46 | <_UsUrPeR_> one moment. let me check that.
| |
12:49 | gadi: no. It does not work.
| |
12:49 | <Gadi> you still have the: -r sound:local option?
| |
12:50 | <bieb> Gadi: syslogs are 0 bytes.. think we had turned it off way back.. dhcpd is not adjusted.. we use MS server to handle DHCP (it does dhcp for rest of company) all that was changed in the DHCP server was the new IP of the ltsp server
| |
12:50 | <_UsUrPeR_> gadi: that is correct, yes
| |
12:51 | <Gadi> bieb: thats an important piece of info
| |
12:51 | :)
| |
12:51 | <bieb> :)
| |
12:51 | <Gadi> bieb: go back to your pxelinux.cfg/default
| |
12:51 | <bieb> ok
| |
12:52 | <Gadi> and instead of nbdport
| |
12:52 | use: nbdroot=<ip-of-server>:2000
| |
12:52 | <bieb> ok
| |
12:52 | <Gadi> _UsUrPeR_: ps -efw|grep rdesktop verifies that it is called with that option?
| |
12:54 | <_UsUrPeR_> Gadi: correct. It's showing "rdesktop -r sound:local <server ip>"
| |
12:54 | <Gadi> is this 10.10?
| |
12:54 | <_UsUrPeR_> Gadi: 10.04
| |
12:55 | <Gadi> doesnt make sense
| |
12:55 | can you transfer a wav file to the chroot and play it with "aplay <filename>"
| |
12:55 | <_UsUrPeR_> heh. ok, that will take a second
| |
12:56 | <Gadi> just grab something from /usr/share/sounds
| |
12:56 | or some such
| |
12:57 | <_UsUrPeR_> just updating the image now
| |
12:57 | <Gadi> you could have just scp''d it to the running image
| |
12:57 | :)
| |
12:59 | <_UsUrPeR_> fffffffff
| |
12:59 | now all images will have this .wav dammit! :)
| |
12:59 | my official decree :)
| |
13:00 | <bieb> Gadi: changed the default config to nbdroot.. ran ltsp-update-image.. still get the same 2 notes at the end about port use and nothing being done.. boot client.. and same issue
| |
13:01 | <_UsUrPeR_> gadi: aplay does work
| |
13:03 | gadi: have you verified this works for you?
| |
13:21 | jtwood222 has joined #ltsp | |
13:22 | <jtwood222> When using alternate authentication, say kerberos or ldap, is it as simple as configuring pam to use these authentication methods on the LTSP server and configuring ssh to use PAM?
| |
13:22 | Thus allowing the LTSP clients to login with kerberos or ldap?
| |
13:26 | <Gadi> sorry, guys
| |
13:26 | was on a call
| |
13:26 | <_UsUrPeR_> no problem :)
| |
13:27 | <jtwood222> Gadi: no problem
| |
13:27 | <Gadi> _UsUrPeR_: I certainly have run rdesktop with sound
| |
13:27 | <_UsUrPeR_> jtwood222: I have gotten openLDAP and LTSP to work with each other
| |
13:27 | jtwood222: totally possible
| |
13:27 | <Gadi> _UsUrPeR_: do you have an ubuntu laptop handy - so you can check from there
| |
13:28 | <_UsUrPeR_> Gadi: sure. Let me give that a shot.
| |
13:28 | <Gadi> jtwood222: yeah, thats exactly how it works
| |
13:28 | <_UsUrPeR_> any different parameters for me to try?
| |
13:28 | <Gadi> _UsUrPeR_: shouldnt need any
| |
13:28 | jhutchins_lt has quit IRC | |
13:28 | <_UsUrPeR_> k
| |
13:29 | <Gadi> bieb: you dont need to update the image when changing pxelinux.cfg/default
| |
13:29 | in fact, just doublecheck that updating the image didn't *change* your pxelinux.cfg/default
| |
13:30 | <jtwood222> Yeah, I figured and hoped that was how it worked...since I already have my WinAD working for authentication with everything. I would also assume that Unix Schema Extension would supply the home directory for the ltsp user and I could use pam_mount to mount the filesystem for the home directory...
| |
13:30 | <Gadi> jtwood222: are you using likewise?

13:31 | good

13:31 | <_UsUrPeR_> Gadi: same problem with a 10.04 desktop environment. rdesktop -r sound:local <server ip>
| |
13:31 | <bieb> Gadi: no change to default
| |
13:31 | <Gadi> _UsUrPeR_: sounds like it is a server side config problem
| |
13:31 | :)
| |
13:31 | <_UsUrPeR_> :PPP
| |
13:32 | ok, if it works with windows remote desktop, does that mean that it could still be a problem?
| |
13:32 | it = server

13:32 | in Windows, remote sound works

13:33 | <_UsUrPeR_> hahaha
| |
13:34 | <bieb> other than dhcp.. what else should I be checking to get the desktop to load?
| |
13:34 | <Gadi> bieb: you can do this:
| |
13:34 | in pxelinux.cfg/default
| |
13:34 | add: break=bottom
| |
13:34 | that will drop you to an initramfs prompt
| |
13:35 | <bieb> k
| |
13:35 | <Gadi> just after it was supposed to mount the stuff that it didnt
| |
13:35 | at the prompt, type ifconfig
| |
13:35 | and see if it got an IP
| |
13:35 | maybe the interface didn't come up
| |
13:36 | which could be a dhcp setting issue
| |
13:36 | see, here's the deal
| |
13:36 | <bieb> I can do that now right? because that is where it leaves the client during the boot
| |
13:36 | <Gadi> PXE gets an IP address from the DHCP
| |
13:36 | ah, right
| |
13:36 | so yeah, at the initramfs prompt, poke around a bit
| |
13:36 | <bieb> without adding break=bottom
| |
13:36 | <Gadi> right
| |
13:37 | anyhow, in the initramfs,
| |
13:37 | <bieb> ok.. so ifconfig... anything else? should I try to mount things manually?
| |
13:37 | <Gadi> the client gets its IP for a second time
| |
13:37 | <bieb> ahh
| |
13:37 | <Gadi> and then tries to mount nbd
| |
13:38 | now, where does it know the nbd server?
| |
13:38 | well, usually it uses the dhcp server
| |
13:38 | alas, for you, that is bad
| |
13:38 | so, nbdroot=<ip>:2000
| |
13:38 | should tell it to use that IP
| |
13:38 | <bieb> right
| |
13:38 | <Gadi> which is the IP of your ltsp server
| |
13:40 | nbd-client $NBD_CLIENT_ROOT_SERVER $NBD_ROOT_PORT /dev/nbd0
| |
13:41 | make appropriate substitutions
| |
13:41 | <bieb> everything worked yesterday prior to the network changes.. once the ltsp server had a new IP, that scope was added to the Win Dchp server.. the thing I missed was updating the sshkeys and image.. we would get to the login screen but it would fail authentication.. once I ran the ltsp-update-sshkeys && ltsp-update-image.. thats when it stopped loading..
| |
13:41 | <Gadi> right
| |
13:41 | I'm with ya
| |
13:43 | <bieb> I hate things getting broken on a friday
| |
13:43 | <jtwood222> bieb: AMEN to that!
| |
13:44 | <Gadi> worst thing to break on a friday is the beer glass
| |
13:45 | <bieb> very true
| |
13:45 | <jtwood222> Haha...LMAO
| |
13:45 | <bieb> ok.. off to check ifconfig..
| |
13:45 | <Gadi> bieb: we'll get it going
| |
13:45 | its only plumbing
| |
13:45 | :)
| |
13:47 | <jtwood222> Gadi: So you asked if I was using likewise...I am guessing that one way or another makes it difficult?
| |
13:47 | This setup is entirely in testing right now, so if likewise would be better way to go for ldap auth through a winad...
| |
13:49 | <Gadi> well, I just got my bottom burned a bit by likewise
| |
13:49 | so< i would have given you some cautionary advice
| |
13:50 | seems they don't test much on multiuser environments
| |
13:50 | and a bunch of folks trying it with LTSP (myself included) would find that it would crap out after a certain number of users log in
| |
13:50 | <jtwood222> Oh really? That is almost useless then...ouch
| |
13:50 | <Gadi> (daemon would hang, system grinds to a halt or doesnt let future logins)
| |
13:51 | but, they gave me a version that is supposed to fix that problem
| |
13:51 | <jtwood222> I am glad I just went with the good ol' standy then
| |
13:51 | <Gadi> have yet to try it out
| |
13:51 | and confirm
| |
13:51 | because Im still wiping the egg off my face
| |
13:52 | aside from that issue, likewise was going great
| |
13:52 | so, I won't turn away from it
| |
13:52 | <jtwood222> No doubt...I am just dabbling in replacing a lot of out M$ stuff with somewhat more robust and configurable (and in my mind a lot more stable) software...I would rather purchase support from the developers or donate then pay M$ licensing and be stuck
| |
13:53 | The AD Server and the TS Server are the only two we will keep...because AD is HARD to get away from once you've used it and there is unfortunately some software that you need Windows to run
| |
13:53 | <Gadi> well, for this particular issue we lie in a weird nexus of the universe
| |
13:54 | right
| |
13:54 | have you been using seamlessrdp?
| |
13:54 | thats another one on my $hitlist
| |
13:54 | <jtwood222> No, haven't run into that...looking for it right now
| |
13:55 | <Gadi> hehe
| |
13:55 | fun times
| |
13:55 | ahead
| |
13:55 | lol
| |
13:58 | <bieb> Gadi: ifconfig works and shows the correct client ip
| |
13:58 | <Gadi> bieb: excellent!
| |
13:58 | <bieb> if we make any changes to the win dhcp server.. I dont have to update the image correct?
| |
13:58 | it is just directing the clients
| |
13:58 | <Gadi> right
| |
13:58 | we prolly wont touch it
| |
13:59 | have you tried the nbd-client command?
| |
13:59 | (at the initramfs prompt)
| |
13:59 | <bieb> no..
| |
14:00 | nbd-client $NBD_CLIENT_ROOT_SERVER $NBD_ROOT_PORT /dev/nbd0 correct?
| |
14:00 | <Gadi> but substitute
| |
14:00 | with actual server ip and port
| |
14:01 | <bieb> so... ndb-client 172.18.16.25:2000 /dev/nbd0??
| |
14:01 | <Gadi> no colon
| |
14:02 | <bieb> space?
| |
14:02 | <Gadi> nbd-client 172.18.16.25 2000 /dev/nbd0
| |
14:02 | <bieb> ipcool
| |
14:02 | lol
| |
14:02 | ok..let me try that
| |
14:02 | <jtwood222> Gadi:Oh beautiful...so from the quick look, its like an windows applications server pseudoclient
| |
14:03 | <Gadi> what is?
| |
14:05 | <jtwood222> seamless rdp...
| |
14:05 | <bieb> Gadi: it gives a bunch of errors.. how can I make it stop so I can see the first error.. |more at the end didnt work
| |
14:06 | <Gadi> well, what kind of errors are they?
| |
14:12 | mistik1 has quit IRC | |
14:12 | <Gadi> jtwood222: yeah, it is an extension of rdesktop -> but it is mostly a hack - especially now that W2K8 allows you to publish applications.
| |
14:13 | <jtwood222> Gadi: Yeah, I see that...but I am interested in exactly how it works with the M$ licensing...
| |
14:14 | Gadi: Have you played around with it at all? I know we have a couple of applications that our users/management will not move away from...otherwise Windows would be pretty much gone...
| |
14:14 | <bieb> Gadi: End Request: I/O error, dev ndb0, sector 0
| |
14:14 | ldm_validate_partition_table (): disk read failed
| |
14:15 | <Gadi> bieb: try this on the server:
| |
14:15 | sudo pkill nbd
| |
14:16 | jtwood222: dont read too much into it - you are just bringing up single aapps off the WTS using RDP, seamless just helps drop the Linux window decorations
| |
14:16 | <bieb> anything else with the pkill? or after it?
| |
14:16 | <Gadi> you still need to do all of the plumbing
| |
14:16 | bieb: then reboot the client
| |
14:16 | <bieb> ok
| |
14:16 | <jtwood222> Gadi: I did wonder if pam_mount mounting the filesystem on for the homedirectories on the LTSP server would be an appropriate way to mount the homes for the ltsp clients...I guess I am not exactly positive on the way the auth/fs mounting on the clients work...
| |
14:18 | Gadi: Gotcha on seamless...it still sounds like a good thing to check into anyway...I'll have to play with it to really know
| |
14:18 | <Gadi> jtwood222: yeah - I find seamless to be a bit quirky
| |
14:18 | also, I usually have to write a wrapper to rdesktop so users have "single sign on"
| |
14:18 | for those apps
| |
14:19 | its all a mess
| |
14:19 | and all a lot of feeling ur way in the dark
| |
14:19 | <jtwood222> Gadi: I was worried about that part of it...I've had enough feeling my way in the dark with the voodoo AD/Linux Integration
| |
14:19 | <Gadi> yeah
| |
14:20 | I think ur alternatives to dark feeling are all commercial
| |
14:20 | <jtwood222> Yes...they definitely are...
| |
14:20 | <Gadi> OSS is good at providing lots of pieces
| |
14:20 | not usually so good (or willing) to put them all together
| |
14:21 | <jtwood222> The problem is, those commercial alternatives, some of them just brute force everything together from what I have seen and don't work well with anything outside their package
| |
14:21 | kalib has quit IRC | |
14:21 | <jtwood222> Yeah, but once you understand how the pieces work, it gets easier to make them work together...PAM was a big stumbling block for me...I know that...
| |
14:24 | <bieb> Gadi: same thing
| |
14:24 | <Gadi> bieb: the server and clients are on the same subnet?
| |
14:25 | komunista has joined #ltsp | |
14:25 | <Gadi> bieb: and the client can ping the ltsp server from the initramfs?
| |
14:26 | <bieb> initramfs doesnt have ping
| |
14:26 | <Gadi> crap
| |
14:26 | <bieb> they are on same subnet
| |
14:26 | <Gadi> ah, can the server ping it?
| |
14:26 | <bieb> let me try that
| |
14:26 | <Gadi> we know the problem is with nbd-client
| |
14:27 | the question is: why can't nbd-client connect to your nbd-server on port 2000
| |
14:27 | <vagrantc> firewall?
| |
14:27 | <Gadi> show me, firewall!
| |
14:28 | *audience applause*
| |
14:29 | <bieb> Gadi: server --> client ping = GOOD
| |
14:30 | <Gadi> bieb:
| |
14:30 | on the server, do:
| |
14:30 | sudo tail -f /var/log/syslog
| |
14:30 | then reboot the client
| |
14:30 | and watch the syslog screen
| |
14:30 | <bieb> ok
| |
14:30 | <Gadi> and see if nbd-server fires at all
| |
14:31 | if not, hit ctrl-c
| |
14:31 | check your /etc/inetd.conf
| |
14:31 | make sure port 2000 is set correctly there
| |
14:31 | and: sudo service openbsd-inetd restart
| |
14:31 | for good measure
| |
14:31 | <bieb> what should it say for port 2000?
| |
14:32 | <Gadi> 2000 stream tcp nowait nobody /usr/sbin/tcpd /usr/sbin/nbdrootd /opt/ltsp/images/i386.img
| |
14:33 | or some such
| |
14:33 | <bieb> ok
| |
14:36 | <jtwood222> Gadi: Thanks for the advice with seamless and ldap...much appreciated. I've got some playing around to do...hopefully I don't mangle anything too badly...haha
| |
14:36 | <Gadi> keep in touch
| |
14:36 | we'll bump heads in the dark
| |
14:36 | :)
| |
14:37 | <jtwood222> Absolutely...just curious what your involvement in LTSP is...you seem to be on the ball
| |
14:37 | <Gadi> im one of the devs
| |
14:37 | for many many moons
| |
14:37 | :)
| |
14:37 | <jtwood222> I figured at much....alkisg too?
| |
14:37 | <Gadi> yup
| |
14:37 | tho, my membership card is older and more worn
| |
14:37 | ;)
| |
14:38 | <vagrantc> gadi's one of the only currently developers who predates the muekow/5.0 times
| |
14:38 | * vagrantc pines for sbalneav | |
14:38 | <Gadi> seriously
| |
14:38 | where the heck is he?
| |
14:38 | <jtwood222> Nice...I'm just learning this stuff really...was out of the Unix/Linux world since around 2000 so a lot has seriously changed
| |
14:39 | <Gadi> you missed the lively days of LTSP
| |
14:39 | * Gadi thinks we've sobered up too much since 5.0 | |
14:39 | <Gadi> :)
| |
14:40 | <jtwood222> HAHA...its always lively in the beginning isn't it...
| |
14:40 | <Gadi> well, the global economy hasnt helped
| |
14:40 | <jtwood222> Honestly, my headaches would be a lot fewer without windows...the thing I always know in Linux is that it can be done...Windows...that isn't always true
| |
14:40 | <Gadi> everybody winds up working at 100000%
| |
14:41 | <jtwood222> No, economy is bad...I agree...I work for an oil and gas company, so I've been fortunate...
| |
14:41 | <Gadi> hehe
| |
14:41 | unless you're cleaning the gulf
| |
14:41 | :)
| |
14:42 | <jtwood222> Yeah yeah...I went to school for Engineering, Mechanical & Petroleum and I am one of the computer guys here, so figure that out. I just happened to end up doing control systems for a while and ended up into networking and admin work
| |
14:42 | * Gadi is a EE | |
14:43 | <jtwood222> Where you at in this big old world, Gadi?
| |
14:43 | <Gadi> just north of NYC
| |
14:43 | u?
| |
14:43 | <jtwood222> Erie, PA
| |
14:43 | <Gadi> ah!
| |
14:43 | <jtwood222> closest city anyway
| |
14:43 | * Gadi is a Quaker | |
14:44 | <Gadi> (in the UofP variety)
| |
14:44 | <vagrantc> hrm?
| |
14:44 | <Gadi> (not the quaker oats kind)
| |
14:44 | <bieb> Gadi: you went to UofP?
| |
14:44 | <Gadi> yup
| |
14:44 | <jtwood222> I did the PSU route
| |
14:44 | <bieb> cool.. I gre up in Philly.. now in Atlanta
| |
14:44 | <jtwood222> Damn, small world here...
| |
14:44 | <bieb> jtwood222: my favorite school
| |
14:44 | <Gadi> sure is
| |
14:45 | <jtwood222> I live in Texas now--but looking like I am moving back north...
| |
14:45 | TheGuy has joined #ltsp | |
14:45 | <jtwood222> Been here for projectes for months...
| |
14:46 | Well, you guys have a good evening...I need to go start the ol' diesel and get her warmed up for the miserable drive in the snow...
| |
14:46 | <Gadi> yeah, I gotta run, myself
| |
14:46 | bieb: where are we at?
| |
14:46 | mistik1 has joined #ltsp | |
14:46 | <jtwood222> later all...
| |
14:47 | jtwood222 has quit IRC | |
14:47 | jtwood has quit IRC | |
14:48 | <bieb> Gadi: http://pastebin.com/RZVccKX4
| |
14:48 | TheGuy has left #ltsp | |
14:49 | <Gadi> is that the IP of the client?
| |
14:49 | <bieb> yep
| |
14:49 | <Gadi> then, nbd is fine
| |
14:49 | I think your image file is bad
| |
14:49 | <bieb> crapppppppppppppp
| |
14:49 | <Gadi> dont panic
| |
14:49 | make sure you are not low on disk space or something
| |
14:50 | thn:
| |
14:50 | sudo mv /opt/ltsp/images/i386.img /tmp/i386.img.backup
| |
14:50 | sudo ltsp-update-image
| |
14:50 | and make it fresh
| |
14:51 | all those I/O errors you were getting
| |
14:51 | can't be good
| |
14:51 | it means it has trouble reading from the image
| |
14:51 | <bieb> ok.. so it will be an empty image?
| |
14:51 | <Gadi> no no
| |
14:51 | <bieb> ok
| |
14:52 | <Gadi> it creates the image FROM /opt/ltsp/i386
| |
14:52 | <bieb> whewwww
| |
14:52 | gotcha
| |
14:52 | how soon are you heading out?
| |
14:53 | <Gadi> 5 min
| |
14:53 | <bieb> damn
| |
14:53 | <Gadi> well, lets go over what we know
| |
14:53 | always easier this way:
| |
14:53 | nbd-client is what is reporting the IO errors
| |
14:53 | _UsUrPeR_ has quit IRC | |
14:54 | <Gadi> but, the client is working -> nbd-server sees it request the file
| |
14:54 | <bieb> right
| |
14:54 | <Gadi> and exports it
| |
14:54 | so, either there is something wrong with the file
| |
14:54 | alkisg_android has joined #ltsp | |
14:54 | <Gadi> or there is something wrong with nbd reading the file
| |
14:54 | <bieb> ok
| |
14:54 | <Gadi> you are checking the first one
| |
14:55 | <bieb> right
| |
14:55 | <Gadi> by rcreating a brand new image file
| |
14:55 | but, of course, it may still fail
| |
14:55 | <bieb> right
| |
14:55 | <Gadi> because all the other times it was created, it failed
| |
14:55 | as for the second option,
| |
14:56 | was there any sort of change in block sizes or any other network change that happened when they changed the scope on you?
| |
14:56 | <bieb> no
| |
14:56 | <Gadi> yeah, didnt think so
| |
14:56 | also, you had a working image
| |
14:56 | before you updated the image
| |
14:56 | <bieb> yep
| |
14:57 | <Gadi> so, something in the image update gave you an image that nbd doesn't like
| |
14:57 | tell me, is this a server you can reboot safely>
| |
14:57 | ?
| |
14:58 | because I wonder if there might not be something else that is gumming things
| |
14:58 | up
| |
14:58 | <bieb> yeah.. and it has been rebooted a couple times today.. I went into likewise and disconnected from the domain.. then reconnected, 2 different times
| |
14:59 | <Gadi> so, if the update image fails again
| |
14:59 | try rebooting the server
| |
14:59 | and then rebooting the client
| |
14:59 | <bieb> ok
| |
14:59 | <Gadi> crappy kind of solution
| |
14:59 | :)
| |
14:59 | <bieb> I know
| |
14:59 | I will take whatever works
| |
14:59 | <Gadi> I figured
| |
14:59 | :)
| |
15:00 | good luck, bieb
| |
15:00 | I gotta run
| |
15:00 | <bieb> this would not have been so bad next weekend.. when I am not busy as hell on Saturday, cause I could have used all day Saturday and did a rebuild of the image...
| |
15:00 | thanks Gadi
| |
15:01 | <Gadi> ciao

15:29 | <bieb> Gadi, was helping me with this earlier... but he had to go... my boss and the network admin redesigned out network last night.. changed the way we had subnetting etc. I reset the IP on my ltsp server, and the clients get the boot screen. but authentication does not work. We have AD and I am using likewise-open. I have disconnected and reconnected to the domain, with no luck. Do I have to update the ltsp image for the ip changes??
| |
15:31 | <vagrantc> yes, you'd have to update the ltsp image for the ip to get put into the new ssh key
| |
15:31 | well, the new ssh key/ip address pairing
| |
15:31 | <bieb> hey vagrantc did that..
| |
15:32 | let me try to run down what gadi tried..
| |
15:32 | we did the ltsp-update-sshkeys && ltsp-update-image
| |
15:32 | when the clients boot they get to the initramfs screen
| |
15:33 | from there I did ifconfig.. the clients are getting the correct IP
| |
15:33 | I can ping the client from the server
| |
15:34 | I have tailed the syslog.. here is the pastebin... http://pastebin.com/tt2pLjmV
| |
15:34 | I don't know what the first line means.. or if it is good or bad
| |
15:35 | we moved the current image file to /temp/img.backup and redid the ltsp-update-image.. still only gets to initramfs
| |
15:36 | netstat'ed the server to make sure it was still listening on port 2000, it is
| |
15:37 | that is all I can think of at the moment
| |
15:37 | :)
| |
15:40 | vagrantc: anything else you can think of?
| |
15:41 | _UsUrPeR_ has joined #ltsp | |
15:46 | <vagrantc> bieb: first line shouldn't be a problem... just some tftp noise
| |
15:47 | not sure what's going wrong
| |
15:47 | everything sounds good up to that point
| |
15:47 | <bieb> yeah its weird
| |
15:48 | I get the ubuntu screen, with the progress line going back and forth.. then balck screen with cursor in the upper left.. then bleccchhhh .. initramfs screen
| |
15:49 | the first error on the initramfs screen is: mount: mounting /dev/nbd0 on /rofs failed: invailid argument
| |
15:50 | then /rofs failes to mount on /root/rofs with invalid arguement

15:57 | <bieb> vagrantc: is there a How to on rebuilding your image from scratch, but keeping the current home directories and permissions??
| |
16:01 | <vagrantc> the home directories aren't in the image
| |
16:02 | bieb: simply removing or moving aside /opt/ltsp/i386 and running ltsp-build-client again should start from scratch.
| |
16:03 | i.e. sudo mv /opt/ltsp/i386/ /opt/ltsp/i386.broken ; sudo ltsp-build-client
| |
16:03 | <bieb> vagrantc: I just want to make sure when I redo the image, we use codeweavers so the students get MS office 2007, I didnt know if there was anything else I would need to do with the Docs in their home dirs

16:03 | <vagrantc> bieb: that's server-side, unless you're doing fatclients or localapps
| |
16:03 | <bieb> I am doing local apps.. but only firefox
| |
16:05 | ok..well this might be a time to fix some issues....
| |
16:05 | since FF is local.. student have a problem opening .pdf files directly from the browser, they have to save to the desktop and then open
| |
16:07 | are fat clients a good option overall?
| |
16:09 | <vagrantc> if your hardware supports it
| |
16:10 | you need more ram and CPU on the clients
| |
16:17 | <bieb> gotcha
| |
16:18 | do I need to run Adobe Reader local to be able to open .pdfs directly from the browser?
| |
16:20 | <vagrantc> the simple answer is yes
| |
16:20 | <bieb> what is the not so simple one?
| |
16:21 | <vagrantc> you could install it locally, and then firefox will use it locally, you could configure your local machine to use remote apps ... you have many choices.
| |
16:22 | if you just install it locally, i think then it will only run when firefox or another locally running program needs to use it
| |
16:22 | you probably don't need to configure it to be used as a localapp
| |
16:23 | <bieb> well how do I tell FF running as a local app to use Adobe Reader as a remote app?
| |
16:24 | <vagrantc> that's an adventure that i don't know off the top of my head :)
| |
16:25 | <bieb> :)
| |
16:25 | is there a how to for it?
| |
16:25 | <vagrantc> the intarwebs would know better than i
| |
16:25 | <bieb> or is it too much of an adventure for the How-to writers?
| |
16:26 | <vagrantc> it relies on a lot of recently developed and not heavily tested features
| |
16:26 | <bieb> ohhhhh
| |
16:27 | well how about this... IS it best practice to run FF as a local app?
| |
16:29 | <vagrantc> it's not a terrible idea ... takes some load off the server
| |
16:29 | <bieb> how many clients do you have?
| |
16:29 | <vagrantc> but localapps have some issues with integrating with other apps, as you've noticed
| |
16:29 | <bieb> yeah they do
| |
16:30 | <vagrantc> the network i work with has about 10-20 terminals ... though different use-cases use different application servers
| |
16:30 | <bieb> I see
| |
16:30 | are you running FF local?
| |
16:30 | <vagrantc> i.e. some log in to a guest server, some have real accounts and such
| |
16:30 | not yet
| |
16:31 | <bieb> I have 13 terminals.. Diskless workstations
| |
16:31 | <vagrantc> i'm working on switching to fatclients as much as i can
| |
16:31 | just don't have the powerful servers to really be able to do thin-clients
| |
16:31 | <bieb> I have the 1520 thin clients
| |
16:32 | <vagrantc> all of the machines in use are just recycled PCs
| |
16:32 | <bieb> server is (2) dual xeon processors, 16gb ram
| |
16:32 | I see
| |
16:32 | <vagrantc> everything from p-II 450MHz w/ 128MB of ram to 2Ghz machines with 512-1024MB
| |
16:33 | <bieb> nice array
| |
16:35 | do you think there would be that big a difference in speed running FF from the server instead of local?
| |
16:37 | <vagrantc> only one way to find out :)
| |
16:38 | <bieb> ohhh.. volunteering me for guinea pig duty?
| |
16:38 | <vagrantc> fairly easy to test

16:58 | <bieb> vagrantc: will I have to configure likewise again? or is that just server based? our students authenticate to AD
| |
16:59 | <vagrantc> bieb: i have no idea what you have to configure in likewise or AD
| |
16:59 | bieb: my guess is no, since you authenticate against the server
| |
16:59 | and you're not deleting the server
| |
17:02 | <bieb> ok cool
| |
17:02 | <vagrantc> almost everything happens on the server.
| |
17:02 | the thin-client is just an extension of the server
| |
17:03 | <bieb> ok.. thanks for the info and help
