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

<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If you're talking about .tar.gz, that may be really out of date...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

root^debian-11: are you using ltsp?
14:00

no

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

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

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

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

<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.

Sound to me that you would be an excellent maintainer for ltsp on fedora/rhel
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.

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.

vagrantc: bcg has some patches for ltsp support in rhel7, and I suggested to him that he could become a maintainer if he'll be using ltsp on rhel for a while
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...)

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 :)
