| 04:37 | <alkisg> So after all those bug fixes, does it work at all?
| |
| 04:37 | <vagrantc> ltsp-config nbd-server basically works
| |
| 04:38 | dnsmasq support is kinda borked
| |
| 04:38 | the install_examples function doesn't seem to handle no language extension ... even though it looks like it should
| |
| 04:39 | <alkisg> Ouch, /me has a lot of work to do on Sunday then :)
| |
| 04:40 | Ah and we need to modify postinst to actually use ltsp-config
| |
| 04:40 | <vagrantc> isc-dhcp-server seemed to work, although on debian it will require modifying /etc/dhcp/dhcpd.conf
| |
| 04:41 | <alkisg> We can put overridable functions like in other tools
| |
| 04:41 | <vagrantc> won't be able to do so for the potential policy violations
| |
| 04:41 | <alkisg> In ubuntu's postinst we do modify the nbd-server configuration anyway
| |
| 04:42 | ...but since no images exist at that point, we should probably remove it from there...
| |
| 04:42 | <vagrantc> nbd-server in debian configures /etc/nbd-server/config by default now
| |
| 04:42 | oh, new upload of nbd today... hopefully for the best
| |
| 04:43 | <alkisg> Hmm we'd need to modify our check for when to start nbd-server
| |
| 04:43 | Because before, ltsp-config nbd-server would start nbd-server if no config was found,
| |
| 04:43 | but if nbd-server ships a config, it should check conf.d/* instead
| |
| 04:44 | Or check if nbd-server is running
| |
| 04:44 | <vagrantc> the service function is weird ...
| |
| 04:44 | <alkisg> How can we make it better?
| |
| 04:45 | E.g. in gentoo they manually run the services with /usr/sbin/*...
| |
| 04:45 | <muppis> Hopefully it's only me. Alt-Tab (nor Alt-Abovetab) doesn't work in 12.04 fat with unity.
| |
| 04:45 | <vagrantc> it should check for service in $PATH
| |
| 04:45 | alkisg: debian has both service and invoke-rc.d ... it we should prefer service if it's available
| |
| 04:46 | <alkisg> Ah, I thought it was the other way around
| |
| 04:46 | So, service if it exists, invoke-rc.d if it exists, and finally fall back to running the service from path?
| |
| 04:46 | <vagrantc> actually, i'm not sure now ... the service thing is newish
| |
| 04:47 | <alkisg> muppis: I haven't seen that behavior... try with a new user?
| |
| 04:48 | <vagrantc> alkisg: what i don't know is if service will respect policy-rc.d and stuff like that...
| |
| 04:48 | but service seems to support upstart if it's installed, which would be good.
| |
| 04:50 | <alkisg> vagrantc:
| |
| 04:50 | alkisg@alkis:~$ sudo strace -e trace=file service nbd-server start 2>&1 | grep policy
| |
| 04:50 | alkisg@alkis:~$ sudo strace -e trace=file invoke-rc.d nbd-server start 2>&1 | grep policy
| |
| 04:50 | stat64("/usr/sbin/policy-rc.d", {st_mode=S_IFREG|0644, st_size=20, ...}) = 0
| |
| 04:50 | ...no checks
| |
| 04:50 | <vagrantc> hmmm.
| |
| 04:50 | maybe would be better to default to invoke-rc.d, then.
| |
| 04:55 | * alkisg wishes a good day/night etc to all, bb | |

| 19:39 | <alkisg> vagrantc: can we submit ltsp manpage updates for wheezy in e.g. a couple of weeks?
| |
| 19:39 | <vagrantc> alkisg: probably, though depends on how invasive the changes are
| |
| 19:39 | alkisg: if it requires a new build system or something, ugh
| |
| 19:39 | <alkisg> No, nothing like that
| |
| 19:40 | E.g. ltsp-update-image still mentions port 2000 etc
| |
| 19:40 | <vagrantc> if it's just a straight update of the documentation, should be fine.
| |
| 19:40 | Phantomas has left IRC (Phantomas!~Phantomas@unaffiliated/phantomas, Ping timeout: 252 seconds) | |
| 19:40 | <alkisg> Some of the tools have very different command line options now too, and some of them lacked the options in the manpage the first place
| |
| 19:41 | Cool, so I'll focus on testing for now, and do the manpages later on
| |
| 19:41 | * alkisg just found out that firefox supports `man:ltsp-update-image` URLs :) | |
| 19:41 | <vagrantc> waaah.
| |
| 19:41 | :)
| |
| 19:42 | <muppis> alkisg, not in Windows. ;)
| |
| 19:42 | <alkisg> Haha
| |
| 19:43 | <Hyperbyte> muppis, that's a bad joke and you should feel bad.
| |
| 19:43 | <alkisg> Meh Ubuntu Greek translators decided that some of my upstream greek translations for epoptes weren't good enough! :D :D
| |
| 19:43 | <muppis> Hyperbyte, it wasn't a joke.
| |
| 19:43 | <Hyperbyte> muppis, you mean you really are using Windows? :o
| |
| 19:43 | <vagrantc> alkisg: here's to peer review!
| |
| 19:43 | <muppis> Rebuilding my ltsp enviroment, so had to use Windows 7 for a while.
| |
| 19:44 | <Hyperbyte> muppis, sinner! Blasphemer!
| |
| 19:44 | ;-)
| |
| 19:45 | <muppis> Hyperbyte, what I can say... No Force Feedback -compliant system in Linux, so had to use for gaming also.
| |
| 19:46 | <Hyperbyte> muppis, I'm just teasing you... using Windows 7 myself, for audio editing/recording mainly. :)
| |
| 19:46 | <alkisg> What's wrong with audacity? Which tool are you using in windows?
| |
| 19:47 | <muppis> Hyperbyte, I noticed. :)
| |
| 19:47 | * alkisg is using windows for ... chkdsk /f ntfs volumes :P | |
| 19:48 | <Hyperbyte> alkisg, Adobe Audition.
| |
| 19:48 | <muppis> In some machines I used Windows to just visit http://goodbye-microsoft.com with IE..
| |
| 19:48 | <Hyperbyte> And there's lots of stuff wrong with Audacity
| |
| 19:50 | <alkisg> I used to work with cooledit pro years ago, but I don't think it was too much better than audacity
| |
| 19:50 | No idea how better it's now that adobe has it
| |
| 19:50 | <muppis> I think I should get some sleep. My kids are sleeping long if they aren't waking me up at 7.00 atleast.

| |
| 20:37 | <muppis> :D
| |
| 20:37 | But it happens in all clients.
| |
| 20:39 | <alkisg> Run ldminfod on the server (or the client, if you use fats) and see what sessions it lists

| 21:11 | <msignor> hello - can anyone point me in the best direction for troubleshooting my NFS home mount? Specifically why it would not be working?
| |
| 21:12 | I am able to properly mount by hand - and the lts.conf is properly modified. There is only one in the tftp root folder as well, but no way to confirm that is where it is being read from
| |
| 21:13 | <muppis> In which distro?
| |
| 21:13 | Parker955 is now known as Parker955_Away | |
| 21:15 | <msignor> debian squeeze server / ubuntu chroot
| |
| 21:15 | <muppis> o.O
| |
| 21:16 | <msignor> yeah. my server is low power (500mhz) and is also my nfs server for some file sharing
| |
| 21:16 | but i built an ubuntu chroot as it was much easier / faster than going the straight debian way
| |
| 21:17 | (using fat client btw)
| |
| 21:17 | <muppis> Ah.
| |
| 21:17 | Tried autofs_
| |
| 21:17 | ?
| |
| 21:17 | <msignor> nope..
| |
| 21:17 | not that i know of at least
| |
| 21:18 | i honestly had set this up all working at one point. rebuilt my server due to me being dumb.. and now i am trying to piece through what I did to get it all working
| |
| 21:18 | it boots, gets to login, can login, but I have no mounts
| |
| 21:18 | <muppis> Founded that easy to use in most situations where home mount over nfs was needed.
| |
| 21:19 | <msignor> is there a link / page I can read to verify how it should be configured?
| |
| 21:20 | <muppis> Can't give yoy direct url, but google for: ubuntu autofs nfs home
| |
| 21:21 | My GUI is messed up and I can use only tty right now.
| |
| 21:23 | <msignor> hrmn . just googled for it
| |
| 21:24 | shouldn't the lts.conf handle the home mapping by default?
| |
| 21:24 | ie, if you specify "/home" it will try to nfs mount (server):/home to /home?
| |
| 21:27 | <muppis> I'll boot my client so I can see what's the deal.
| |
| 21:30 | Oh, bummmer. I'm using a thin, so I can't really tell how it is mounted in fat.
| |
| 21:30 | <msignor> hrmn
| |
| 21:30 | okay, i appreciate the effort
| |
| 21:31 | perhaps my issue is that I don't really recall what I did to the debian ltsp server to enable it for the squashfs image
| |
| 21:31 | :)
| |
| 21:31 | <muppis> :D
| |
| 21:32 | I rebuild a fat image in no time.
| |
| 21:33 | <vagrantc> msignor: sudo ltsp-update-image
| |
| 21:34 | msignor: and then it should download the file from the tftp dir, if present
| |
| 21:34 | msignor: what version of ubuntu?
| |
| 21:34 | <msignor> 10.04 is my chroot
| |
| 21:34 | server is deb squeeze
| |
| 21:34 | Phantomas has left IRC (Phantomas!~Phantomas@unaffiliated/phantomas, Ping timeout: 252 seconds) | |
| 21:34 | <msignor> (i rebuild the chroots via an nfs mount -- ie: my local /opt/ltsp is an nfs mount to the server /opt/ltsp)
| |
| 21:35 | maybe this is what is breaking things?
| |
| 21:35 | my notebook is core 2 so much faster than the slow 500mhz server..
| |
| 21:36 | <vagrantc> msignor: you could also build the image on the ubuntu side, and just deploy it in /opt/ltsp/images/
| |
| 21:36 | <msignor> copy / paste you mean?
| |
| 21:36 | <vagrantc> oh, but the ltsp-update-sshkeys will be wrong
| |
| 21:36 | msignor: no idea what you mean about copy and paste ...
| |
| 21:37 | <msignor> you meant copy the image if compressed locally to the server right
| |
| 21:38 | also, I ltsp-update-sshkeys on the server prior to the rebuild image
| |
| 21:38 | <vagrantc> yes, but ltsp-update-image will "fix" it for you if you run from the wrong place
| |
| 21:39 | <msignor> should I just try updating the image from the server and deal with the 2 hour rebuild?
| |
| 21:39 | <vagrantc> either that or manually hack your own copy of ltsp-update-image
| |
| 21:40 | <msignor> should I be concerned that I am not running tftp in the standard root folder?
| |
| 21:40 | i have it moved to /tftpboot
| |
| 21:41 | <vagrantc> should still work
| |
| 21:41 | at least, that used to be a supported location
| |
| 21:43 | <msignor> Just to clarify on all this: I have a DD-WRT router which gives my IP's and bootp info. I have server (1) which is just a file server and it runs ltsp server as well as the nfs-server, its debian and has tftpd-hpa .. client is just built from my notebook and initially copied into the proper location on the server.
| |
| 21:43 | i don't really recall what other modifications I had done to get it working from the nbd image.
| |
| 21:44 | ... i wouldn't mind starting over for the sake of sanity - but i just don't know what I did to get it working in the first place, heh
| |
| 21:47 | <vagrantc> you've got this all kinds of complicated :P
| |
| 21:47 | <msignor> but of course!
| |
| 21:47 | (im running a very lean, lean network from a power consumption standpoint)
| |
| 21:47 | <vagrantc> you might need to specify NFS_HOME=ip.ad.dr.es:/home in lts.conf
| |
| 21:48 | <msignor> hrmn.. good point...
| |
| 21:48 | let me try
| |
| 21:48 | <vagrantc> given that your dhcp server is on a different ip ...
| |
| 21:50 | <msignor> ok, shouldn't need to rebuild image - just boot and try eh?
| |
| 21:50 | <muppis> Yes.
| |
| 21:50 | Just reboot. ;)
| |
| 21:50 | <msignor> my lil vm is rebooting now, we will see
| |
| 21:50 | Phantomas has joined IRC (Phantomas!~Phantomas@unaffiliated/phantomas) | |
| 21:51 | <muppis> Should that IP come out from the server where image is loaded? As I use DD-WRT's dhcpd as well and never specified any IP to lts.conf to get it working.
| |
| 21:52 | <msignor> nope - no change
| |
| 21:53 | unfortunately i didn't set the root password in the chroot so I can't even see the error messages
| |
| 21:53 | <muppis> put screen_02=shell to lts.conf so you get the root shell in ctrl-alt-f2
| |
| 21:54 | And put screen_07=ldm if you want the graphics at same time. :)
| |
| 21:55 | <msignor> now this is weird. I logged into the terminal as root
| |
| 21:56 | try to mount the nfs path to some random path, and get operation not permitted
| |
| 21:56 | yet the same path works from another machine
| |
| 21:56 | <muppis> Too strict sharing at nfs server?
| |
| 21:56 | <msignor> dont think so. its set to wildcard
| |
| 21:57 | /mnt/ssd/home *(rw,no_root_squash,sync,no_subtree_check)
| |
| 21:58 | (/home is a symlink to /mnt/ssd/home)
| |
| 22:00 | <muppis> I think I'm getting too tired to think clearly. It's 1.00am here.
| |
| 22:00 | <vagrantc> msignor: do you have nfs-common installed in the chroot?
| |
| 22:01 | <muppis> And my kids will kick me up in 6 hours, so I'll catch some sleep. Nights.
| |
| 22:01 | * vagrantc waves to muppis | |
| 22:01 | <msignor> yeap - already tried that, when i did install nfs-common in the chroot, it just updated to the current version
| |
| 22:01 | * muppis waves back to vagrantc | |
| 22:04 | <msignor> wellll shit. i just apt-get installed it in the chroot it (un-updated, since I didn't rebuild the image yet) and it worked
| |
| 22:04 | ... like in the booted terminal, since i was root
| |
| 22:05 | looks like I need to rebuild and go from there
| |
| 22:09 | <vagrantc> yup

| 22:42 | <vagrantc> stgraber: is it sane to default UPDATES_MIRROR to be the same as MIRROR for ubuntu?
| |
| 22:43 | regarding: server/share/ltsp/plugins/ltsp-build-client/Ubuntu/010-updates-mirrors
| |
| 23:03 | muppis has left IRC (muppis!muppis@viuhka.fi, Read error: Operation timed out) | |
| 23:03 | <vagrantc> wheee!
| |
| 23:04 | built an Ubuntu chroot on a Debian server using the latest ltsp upstream code simply by passing: VENDOR=Ubuntu ltsp-build-client ...
| |
| 23:04 | muppis has joined IRC (muppis!muppis@viuhka.fi) | |
| 23:04 | <stgraber> vagrantc: yes, the only mirror that's usually different is the security mirror (security.ubuntu.com to avoid the mirroring delay)
| |
| 23:07 | <vagrantc> stgraber: ok, i'll push that then.
| |
| 23:07 | saves some download time when using a local mirror and not having to specify both
| |
| 23:07 | stgraber: but the security stuff is usually also mirrored to the same location?
| |
| 23:08 | <stgraber> yeah, most mirrors also mirror security but we never recommend using them as we want security updates pushed out as soon as possible
| |
| 23:08 | <vagrantc> stgraber: er, security stuff is often also mirrored to the "regular" mirrors?
| |
| 23:08 | stgraber: for testing, is probably fine, though
| |
| 23:09 | <stgraber> I believe it's the same model as Debian, encourage users to use local mirrors to reduce load on the main mirrors but recommend using the central security mirror to avoid the delay in case of emergency
| |
| 23:09 | <vagrantc> in Debian, i don't think security mirrors are mirrored at all, as far as i know.
| |
| 23:10 | stgraber: so for new installs, it might make sense to add an entry for both $MIRROR $DIST-security as well as security.ubuntu.com $DIST-security ?
| |
| 23:10 | with the $MIRROR hit first?
| |
| 23:11 | <stgraber> I think from a bandwidth point of view it'd be best to just have:
| |
| 23:12 | $MIRROR $DIST
| |
| 23:12 | $MIRROR $DIST-updates
| |
| 23:12 | security.ubuntu.com $DIST-security
| |
| 23:12 | or you'll end up downloading the listing for -security twice
| |
| 23:12 | security updates get copied to -updates, so in most cases if your local mirror is up to date, you'll get them from there
| |
| 23:13 | <vagrantc> but you'd also reduce the load on the security mirror for any updates that got mirrored
| |
| 23:13 | ah.
| |
| 23:13 | well, i'll push the change for -updates to default to $MIRROR
| |
| 23:14 | and the ordering should probably put the security mirror last ...
