| 09:01 | <gdi2k> alkisg, thanks for the hint regarding SCREEN_02=shell the other day. Unfortunately it doesn't work for me, which makes me think that my lts.conf is being completely ignored
| |
| 09:02 | I have 2 other servers, and lts.conf is fine, but on this server, it seems it is being ignored
| |
| 09:04 | <alkisg> try `sudo getltscfg -a -c /var/lib/tftpboot/ltsp/i386/lts.conf`, on that server
| |
| 09:04 | <gdi2k> I don't have getltscfg
| |
| 09:04 | command not found
| |
| 09:04 | <alkisg> /opt/ltsp/chroot/usr/bin/getltscfg
| |
| 09:05 | <gdi2k> I don't have the chroot on this server - I only copied the complete image and boot directories from the "master" server
| |
| 09:05 | was thinking that wasn't required :/
| |
| 09:06 | <alkisg> Copy the lts.conf elsewhere and check it there
| |
| 09:06 | <gdi2k> k
| |
| 09:06 | <alkisg> The getltscfg command just tries to check the syntax of lts.conf
| |
| 09:06 | <gdi2k> got it
| |
| 09:06 | <alkisg> So it'll notify you if you have an issue
| |
| 09:08 | <gdi2k> no errors reported http://pastebin.com/FYpYNmi0
| |
| 09:10 | <alkisg> OK then it's not a syntax error
| |
| 09:10 | Is that server 12.04?
| |
| 09:10 | <gdi2k> 14.04
| |
| 09:10 | <alkisg> I don't think 14.04 supports arcfour
| |
| 09:11 | What is the problem you're facing again?
| |
| 09:11 | <gdi2k> hmm, ok. I did try a bunch of configs, and a lot failed, but this one worked
| |
| 09:11 | I would like to use LDM_SERVER="192.168.1.12"
| |
| 09:11 | I want the boot / image server to be separate from the /home server
| |
| 09:11 | <alkisg> And you said that it works on some servers but not on a specific one/
| |
| 09:12 | Or you never managed to do it?
| |
| 09:12 | <gdi2k> I never managed to do it
| |
| 09:12 | but I think the issue is that lts.conf is being ignored
| |
| 09:12 | and therefore LDM_SERVER="192.168.1.12" is being ignored
| |
| 09:12 | (on this particular server)
| |
| 09:12 | <alkisg> lts.conf comes from tftp
| |
| 09:12 | If a client uses another tftp server, you need to put lts.conf there as well
| |
| 09:13 | What's your end goal, to load balance?
| |
| 09:13 | <gdi2k> we have 2 buildings linked via wireless (50 MBPS each way). we have 15 clients in remote building. Was hoping to reduce bandwidth requirements by hosting local boot / image server, so only /home stuff would be pulled across wireless link
| |
| 09:14 | need to think about your tftp statement, that may be my issue...
| |
| 09:14 | ogra_ has left IRC (ogra_!~ogra_@p5098ed03.dip0.t-ipconnect.de, Ping timeout: 260 seconds) | |
| 09:15 | <alkisg> gdi2k: you can do that with a simple FSTAB command
| |
| 09:15 | Ah you also need the user accounts, never mind
| |
| 09:15 | You want to manage the users in one server, not in 2 servers, right?
| |
| 09:15 | <gdi2k> exactly
| |
| 09:15 | we actually have 2 servers with synchronized user accounts for redundancy in the main building, but I really don't want a third

| 09:27 | * fnurl enjoys reading solutions getting worked through - best learning ever! | |
| 09:32 | <alkisg> gdi2k: then LDM_SERVER is indeed the way to do it
| |
| 09:32 | If your client is not reading lts.conf and you can't see, you could unlock the root password in the chroot to be able to login locally without an lts.conf
| |
| 09:32 | But normally, just checking the tftp logs is enough to troubleshoot lts.conf issues
| |
| 09:32 | !tftp
| |
| 09:32 | <ltsp> tftp: Here's a page to help you troubleshoot TFTP problems in Ubuntu: https://help.ubuntu.com/community/UbuntuLTSP/Troubleshooting/TFTP
| |
| 09:43 | <gdi2k> thanks alkisg, I'm pretty sure it's a TFTP issue on the new server at this point - I am unable to pull lts.conf manually using the tftp command, which I am able to do on the other servers. working on figuring it out
| |
| 09:43 | <alkisg> Cool
| |
| 09:45 | cyberorg has left IRC (cyberorg!~cyberorg@opensuse/member/Cyberorg, Ping timeout: 264 seconds) | |
| 09:50 | <gdi2k> alkisg, it's a stupid issue with tftpd-hpa not starting properly on boot. although the "job" is running as per "status tftpd-hpa", "ps ax | grep tftp" shows it is not actually running. Restarting the service with "service tftpd-hpa restart" brings it to life. Ever seen that before?
| |
| 09:50 | <alkisg> gdi2k: I stopped using tftpd-hpa and switched to dnsmasq 5 years ago
| |
| 09:51 | <gdi2k> heh ok
| |
| 09:51 | <alkisg> I heard about tftpd issues with upstart, yes
| |
| 09:51 | I hope they'll be solved now with systemd
| |
| 09:53 | cyberorg has joined IRC (cyberorg!~cyberorg@opensuse/member/Cyberorg) | |
| 09:56 | <gdi2k> alkisg, right, it's liking my lts.conf, and the client is trying to login to the main ltsp server, but there's an auth problem - login screen pauses for some time before refreshing, without logging in. auth.log on main ltsp server shows: ltsp-new1 sshd[24778]: Connection closed by 192.168.1.217 [preauth]
| |
| 09:56 | likely ssh cert issue?
| |
| 09:56 | <alkisg> try ssh'ing from screen_02 to see.
| |
| 09:58 | <gdi2k> it asks me to accept the server to known_hosts, then asks for password, and I can login successfully
| |
| 09:58 | <alkisg> Right, so you need to add those keys to the image
| |
| 09:59 | I.e. create an /etc/ltsp/my-other-server.hosts file
| |
| 09:59 | <gdi2k> inside chroot?
| |
| 10:01 | <alkisg> No, outside it, google it a bit, sorry I don't have much time currently...
| |
| 10:02 | <gdi2k> alkisg, ok thanks for your help, will let you know how I go
| |
| 10:03 | <alkisg> It's related to ltsp-update-sshkeys
| |
| 10:03 | maybe its manpage will have some documentation
| |
| 10:18 | <gdi2k> alkisg, I'm not convinced it's to do with SSH keys; I've copied the image as is from the main server, and clients are logging into the main server again once booted from the new server. Would I really need to update ssh keys in that case?
| |
| 10:23 | <alkisg> If they're using a different ip to connect to it, and they're not using the same hostname, then yes
| |
| 10:27 | <gdi2k> but my main server is still the same - same server, same IP. It's just that the clients are booting off a different server before logging into the main server
| |
| 10:30 | <alkisg> gdi2k: if you try ssh user@server from screen_02 and it prompts you to accept the key, then it's a problem with the keys
| |
| 10:30 | <gdi2k> ok
| |
| 10:30 | <alkisg> Replace user with an existing user, but leave server as it is
| |
| 10:30 | Don't put another hostname or ip there
| |
| 10:30 | With ssh-keygen you can check the keys and pinpoint the issue
| |
| 10:31 | With LDM_SSHOPTIONS you can override the check
| |
| 10:31 | With /etc/ltsp/hostname.hosts you can put your other server's keys
| |
| 10:31 | ...and that's about all the time that I have for free support today, sorry :)
| |
| 10:31 | <gdi2k> thanks for all your help! :)

| 20:46 | <alkisg> vagrantc: hi! if a package A depends on package B, and pre-depends on package C, and the user runs `apt-get install A` while none of them is installed, does that mean that C is going to be installed before B?
| |
| 20:49 | <vagrantc> alkisg: i don't think you can rely on that ... why do you ask?
| |
| 20:49 | alkisg: package B should (pre-)depend on whatever it needs to work correctly
| |
| 20:50 | <alkisg> In sch-scripts we're using various hacks because we don't want the users to have to deal with e.g. questions like "should nbd-client stop all clients declared in /etc/nbd-client.conf?"
| |
| 20:50 | So, sch-scripts uses debconf to answer that question before the nbd-client package is installed
| |
| 20:50 | But as I understand it it's impossible to do it in postinst... so we'll have to keep it in the script that installs sch-scripts
| |
| 20:51 | (we have a wget script && execute script command for them, that adds our repositories, answers debconf questions, and then installs sch-scripts, ltsp etc)
| |
| 20:51 | It would be nice to be less hackish, but I can't find any proper way to deal with a few of such issues without violating the debian policy...
| |
| 20:53 | I'll try to file a bug for it some time, maybe wouter will consider marking that question with lower priority
| |
| 20:53 | <vagrantc> the process for installation is just install a "base" system and then install package A which does all the hacks?
| |
| 20:54 | <alkisg> First we have a tutorial on how to install the base system. This one is not hackish and it's the same for student installations in their houses, or for pcs in the school
| |
| 20:54 | Then we have a command that "upgrades" a normal installation to "ltsp server"
| |
| 20:55 | Which is, wget sch-scripts-installation-script && run sch-scripts-installation-script
| |
| 20:55 | That script adds our repositories ,answers a few debconf questions, and then just apt-get installs sch-scripts, which depends on ltsp etc
| |
| 20:55 | So I was trying to rewrite that script to make it less hackish
| |
| 20:56 | <vagrantc> by moving the hacks into a package?
| |
| 20:57 | <alkisg> If I could do that in a proper way, I could then just tell them to double click on sch-scripts.deb which would take care of everything
| |
| 20:58 | * vagrantc wonders if you could do some of the hacks in preinst | |
| 20:59 | <alkisg> When apt installs A, B and C, does it run all pre-inst scripts first, and all postinst later on?
| |
| 20:59 | Or first A.preinst, then A.postinst, then B.preinst, then B.postinst etc...
| |
| 21:01 | Maybe it would be better to redesign the sch-scripts package so that it doesn't depend on ltsp. But instead to provide a GUI with an option to "setup ltsp". That script then would answer the debconf questions for nbd-client, it would apt-get install ltsp etc...

| 21:03 | <alkisg> Yeah it doesn't show relationships between multiple packages being installed at the same time...
| |
| 21:03 | <vagrantc> yeah, a configuration helper might be a better approach
