| |
| 07:59 | <alkisg> Hello
| |
| 08:07 | <SYS64738> I didn't solve the DNS issue, at the moment I bypassed it using static records in the /etc/hosts in the server
| |
| 08:08 | <alkisg> It's not an ltsp issue though, is it?
| |
| 08:08 | <SYS64738> sure

| 08:15 | <SYS64738> from logs I see that the lts.conf is sent
| |
| 08:15 | May 15 10:15:33 Reziario dnsmasq-tftp[6137]: sent /var/lib/tftpboot/ltsp/amd64/lts.conf to 192.168.67.75
| |
| 08:16 | <alkisg> That's nice, but it doesn't verify that it has no syntax errors
| |
| 08:17 | <bcg> Hello. I've been porting ltsp to RHEL7(-ish) system. Actually I've already got it working. What's your preferred way to submit general and rhel7-specific patches?
| |
| 08:18 | <alkisg> Hi bcg
| |
| 08:18 | Bug reports and bzr merge requests
| |
| 08:18 | <bcg> Current directory structure is just "Redhat" without version number. How to specify rhel6 vs rhel7 patches?
| |
| 08:18 | <alkisg> Eh, the code doesn't support multiple versions of distros
| |
| 08:18 | Are those for ltsp-build-client?
| |
| 08:19 | <bcg> mostly for ltsp-build-client, some for client startup.
| |
| 08:19 | <alkisg> E.g. if you want an init-ltsp.d script to work on rhel6 and rhel7, then you either need to take care to include it only at the packaging step, or create an "if version=xxx" inside the code
| |
| 08:20 | Can you put something to pastebin, to have a quick look?
| |
| 08:20 | E.g. a diff or something?
| |
| 08:21 | <bcg> Packaging step is probably the best then as I've also made spec file.
| |
| 08:22 | <alkisg> The key question is, do you want to keep both versions upstream?
| |
| 08:22 | <bcg> I'll still have to do some cleanup and more testing. This is just initial package to get it running on rhel7.
| |
| 08:22 | <alkisg> Or the rhel6 version is something that you, as the maintainer, will keep local for your packaging needs?
| |
| 08:23 | <bcg> I don't really care. Do you? I have no use for rhel6 anymore.
| |
| 08:23 | <alkisg> Nope then
| |
| 08:23 | It's best to only have the latest version in upstream code
| |
| 08:25 | <bcg> Ok. Then I'll start with generic patches and as last step do rhel6->rhel7.
| |
| 08:25 | <alkisg> So you got the latest upstream ltsp working in rhel7?
| |
| 08:25 | Or is it some older ltsp version?
| |
| 08:25 | <bcg> yep, latest snapshot.
| |
| 08:25 | <alkisg> Cool. How much time did it take you?
| |
| 08:26 | <bcg> about 25 hours.
| |
| 08:26 | <alkisg> Very nice.
| |
| 08:26 | OK, ping either me or vagrantc when you're ready to submit things
| |
| 08:26 | Or when you want feedback
| |
| 08:26 | <bcg> I started with version 5.4.5 and got it working, then upgraded to latest snapshot.
| |
| 08:27 | <alkisg> Hmm when you say snapshot, which one is that?
| |
| 08:27 | <bcg> ...as I'm running 5.4.5 on rhel6.
| |
| 08:27 | <alkisg> If you're talking about .tar.gz, that may be really out of date...
| |
| 08:27 | Latest LTSP is 5.5.9
| |
| 08:27 | <bcg> oh, i mean tar.gz created from bzr trunk head(?).
| |
| 08:28 | 5.5.9 + some commits
| |
| 08:28 | <SYS64738> alkisg: I moved up in the conf the two directives about DNS, now i can see them with getltscfg
| |
| 08:28 | thanks for the hint
| |
| 08:29 | <alkisg> bcg: ok, good
| |
| 08:29 | SYS64738: np
| |
| 08:31 | <SYS64738> the only strange thing in the lts.conf i the [OLD_MONITOR] section
| |
| 08:38 | <alkisg> What's strange about it?
| |
| 08:38 | It's an example on how to use sections

| |
| 14:00 | <alkisg> root^debian-11: are you using ltsp?
| |
| 14:00 | <root^debian-11> no
| |
| 14:01 | <alkisg> Did you follow the steps in epoptes.org/installation?
| |
| 14:01 | <root^debian-11> yes
| |
| 14:01 | on the server, and client
| |
| 14:01 | <alkisg> What's the output of this command, on both the server and the client?
| |
| 14:01 | sudo ls -lha /etc/epoptes

| |
| 14:03 | server
| |
| 14:04 | <alkisg> Your server.crt is 0 bytes
| |
| 14:04 | <root^debian-11> how can i fix that?
| |
| 14:04 | <alkisg> That means that at some point, you tried to run `epoptes-client -c` from the server,
| |
| 14:04 | which tried to download the file from the server and write it to the server,
| |
| 14:05 | which then made the 0 size issue
| |
| 14:05 | On the server, purge epoptes and reinstall it
| |
| 14:05 | E.g. apt purge epoptes epoptes-client; apt install epoptes
| |
| 14:05 | <root^debian-11> owkay
| |
| 14:05 | <alkisg> Then run epoptes-client -c from the client, not from the server
| |
| 14:06 | <root^debian-11> do i need reinstall it on the client?
| |
| 14:06 | <alkisg> No
| |
| 14:06 | <root^debian-11> owkay i gonna try
| |
| 14:07 | gpasswd -a username epoptes
| |
| 14:08 | do i need to do that again?

| |
| 14:12 | error from the client
| |
| 14:18 | <alkisg> read the installation page, the part where you modify /etc/hosts on the client
| |
| 14:18 | there, you put the ip of the server to match the name "server"
| |
| 14:18 | make it so that "ping server" works, before running epoptes-client -c

| 14:28 | <bcg> alkisg: Is https://bugs.launchpad.net/ltsp/+bug/1690824 enough? I prefer git or hg over bzr, but if really needed, I can create pull requests.
| |
| 14:29 | <alkisg> bcg: it's fine; although that's not related to rhel, it's a general feature encanchment
| |
| 14:29 | *enhancement
| |
| 14:30 | <bcg> It is, I want to start with generic patches first.
| |
| 14:30 | <alkisg> But if it e.g. affects 10 files and adds 10 features etc, then a pull request would be better, with separate commits etc
| |
| 14:30 | That one is fine, sure

| 14:49 | <alkisg> There's a thought to switch to git instead of bzr; if you end up being active for months, then we can surely switch there
| |
| 14:56 | <bcg> Is that a promise? :-)
| |
| 15:11 | <alkisg> Sure! We got bitten from rhel/fedora maintainers asking for help for a couple of months and then disappearing, but if someone is here to stay, we could do that much :)
| |
| 15:15 | <bcg> I'm not official rhel/fedora anything (ok, I'm fedora maintainer for sawfish, but not for ltsp). I just work for a company that is using 100+ LTSP clients and want to continue doing that.
| |
| 15:18 | Just looking at my patches... I'll try do bzr, submitting bugs is a bad idea.

| |
| 15:26 | I'm maintaining ltsp on ubuntu, and vagrantc on debian
| |
| 15:37 | <bennabiy> and doing a wonderful job at it as well :)
| |
| 15:47 | <bcg> On my Fedora system: "bzr branch" worked only without launchpad-login. After launchpad-login it doesn't do anything.
| |
| 15:47 | Now I have same problem with "bzr push" after my first commit.

| 15:49 | <bcg> I see it starting ssh to bazaar.launchpad.net with "bzr serve ...", but nothing happens.
| |
| 15:52 | <bennabiy> bcg did you add your key and all in launchpad?
| |
| 15:53 | <bcg> sure.
| |
| 15:54 | "bzr push lp:~bcgss/ltsp/ltsp-rhel" just hangs there after spawning ssh process.
| |
| 15:54 | <bennabiy> bcg: It has been a while since I have done anything with bzr. I like git myself
| |
| 15:54 | <bcg> yeah me too.
| |
| 15:54 | <bennabiy> alkisg: can we please switch to git? ;)
| |
| 15:55 | I think vagrantc would also agree :)
| |
| 15:56 | bcg: is your company currently using LTSP on fedora/rhel?
| |
| 15:56 | <bcg> Yes, on rhel6
| |
| 15:56 | <bennabiy> bcg: did you document what you had to do to get it working?
| |
| 15:57 | bcg: you can always start by contributing documentation to the wiki ;)
| |
| 15:57 | <bcg> We have internal documentatation for that + own rpm files.
| |
| 15:57 | <bennabiy> ah
| |
| 15:58 | <bcg> With my latest rhel7 patches it will be much easier, if I ever get then pushed to lp/bzr.
| |
| 15:59 | I got to go now, back later today or tomorrow.
| |
| 16:01 | <bennabiy> bcg: great!

| |
| 19:01 | He says he has a 100 ltsp client installation in his company, so he might be a good candidate... :)
| |
| 19:01 | He, too, applauds switching to git :D
| |
| 19:02 | So if you want to push your local trees to launchpad, I wouldn't mind switching to git
| |
| 19:02 | (I can also do the conversion, but I think you said that you had some local metadata that you wanted to push...)

| |
| 20:45 | <bennabiy> Just walking with my girls on the weekends I have found about 500cts of sapphires
| |
| 20:46 | so is it official that the repo is switching to git?
| |
| 20:46 | <vagrantc> not sure who would object at this point :)
| |
| 20:47 | alkisg: you proposing to use launchpad's git hosting?
| |
| 20:47 | i've been reasonably happy with launchpad's git support so far, though haven't used it extensively
| |
| 20:48 | mostly, if i can push and pull branches, i'm fine :)
