alkisg, Hi!
09:56
alkisg, Did you finish writing the wiki page fot dnsmasq?
09:56
(in Greek)
09:56
<alkisg>
Hi danboid , yes, ...
09:57
> danboid, the new page is temporarily there: https://pe86.github.io/linux/LTSP/Προχωρημένα/Πολλά_εργαστήρια/
09:57
Don't link to that page as it's a temporary URL, but the content is indeed finalized
09:58
<danboid>
Great, thanks! I'll have a read now
10:04
I'll edit that and add it to the wiki today
10:06
<alkisg>
Nice. danboid , regarding the issue, yeah I'm planning to add a small note "use mbr/single ext4 partition" to keep things simple
10:07
<danboid>
Great, thats all the user needs to know really.
10:07
<alkisg>
Some other things are indeed supported, but it would take a lot of time and space to explain the restrictions, as the same code is used inside the initramfs where the tools are sparse
10:08
<danboid>
alkisg, I failed to fix the kernel /VB issue on our old (but still in use) LTSP server. I removed all old kernels and configs (ie did a purge of kernel packages) but the kernel versions still don't match up
10:08
<alkisg>
We'd need to check via vnc for that
10:08
It'd take too long to do it over chat...
10:08
(as you already looked at all the usual culprits)
10:09
<danboid>
Not sure VNC would work but I could create you a temp SSH account
10:10
We'll hopefully get it replaced within the next couple of weeks with a fully uptodate and modern server
10:10
<alkisg>
Sure, but it's better if you can see what I'm doing with vnc or terminal sharing
10:10
x11vnc -connect alkisg.ltsp.org => for graphics,
10:11
/usr/share/epoptes-client/share-terminal 81.186.20.0 ==> for terminal sharing
10:11
But for terminal sharing you need to ping me to open my side first, I don't have it listening all the time
10:11
While with ssh a malicious technician could plant malware or whatever, without you seeing what he's doing
10:13
<danboid>
Indeed
10:15
I just tried the share terminal command
10:15
socat[34152] E connect(6, AF=2 81.186.20.0:5499, 16): Connection refused
10:15
<alkisg>
"you need to ping me first" :D
10:15
OK opening my side...
10:15
<danboid>
ping
10:15
<alkisg>
Ready
10:18
danboid: essentially I just want to see what bootfilename it provides
10:18
I don't need to ssh to it
10:18
Moment, school, back in a bit...
10:19vsuojanen has left IRC (vsuojanen!~vsuojanen@cable-hml-585682-65.dhcp.inet.fi, Ping timeout: 260 seconds)
10:20
<danboid>
OK, I'll find out now
10:20
<alkisg>
danboid: you want kernel 4.15 on the clients?
10:20
<danboid>
Yeah, the same as on the server
10:20
<alkisg>
Can we move all the extra images aside, so that we're sure they're not interfering?
10:21vsuojanen has joined IRC (vsuojanen!~vsuojanen@cable-hml-585682-65.dhcp.inet.fi)
10:21
<danboid>
Yes
10:27
<alkisg>
Back, checking
10:30
danboid: it's chrootless, right? Can I run ltsp-update-image -c / now?
10:30
<danboid>
Yep
10:30
Ah, I forgot to mention
10:30
<alkisg>
OK as you can see, you did have all those 4.4 kernels and initrds
10:31
<danboid>
We run this monitoring thing called Taniumclient and I often stop that before updating the LTSP image
10:31
<alkisg>
danboid: OK I cancelled ltsp-update-image, do it your way
10:32
<danboid>
I'm not sure if it causes probs or not but it does cause messages during the update
10:32
<alkisg>
Do it inside our shared terminal so that I can see
10:32
<danboid>
yep
10:33
I've not checked that epoptes share terminal script yet, is it using screen?
10:33
<alkisg>
Yes, socat/openssl/screen
10:34
<danboid>
I'll be so relieved to be able to wipe this server and start afresh. I inherited it and it was a mess 3 years ago.
10:35
Now its a very outdated mess
10:35
Its going to be get re-installed and then become the failover
10:36
I'm going to set it up like the new one, Ubuntu 20.04, VM images, soft RAID for the OS and ZFS for home dirs
10:37
OK its updated now#
10:37
I won't be able to check its fixed until tomorrow but I trust you've fixed it. Thanks alkisg!
10:38
I might be able to get solmeone else to check it for me
10:39
In fact I should be able to pxe boot a VM to test it
10:39
once I'm on the VPN, never tried that
10:40
I'll do that wiki page now coz I owe you one :)
10:41
<alkisg>
danboid: the main problem is that you also had a chroot in /opt/ltsp/amd64
10:42
So the kernel was coming from the chroot
10:42
<danboid>
Ahh! I didn't know about that!
10:42
<alkisg>
I do not make money from ltsp nor from the wiki. Do not do it for me
10:42
Do it for you, as a community
10:42
If you want to help each other, that is; I can only help so much.
10:43
<danboid>
Yep. I want to lessen your support burden if I can
10:43
<alkisg>
👍️
10:43
(I closed the shared terminal, it looked ok now)
10:44
<danboid>
Excellent! I hate telling the staff I can't fix stuff, you saved my ass
10:44
I reckon the new server should be up in the next couple of weeks but all sorts of surprise delays could happen
10:45
and our security guys not liking stuff
10:45
Which they have good reason for in many cases
10:56
I made some tweaks / small additios to 3 of the wiki pages last night - chroots, SAMBA DCs and the Ububntu server guide I wrote

alkisg, Check this for me please https://github.com/ltsp/ltsp/wiki/Multiple-LTSP-servers-on-one-network
13:00
I've just give it a once over with the formatting, should be good now
14:14
<alkisg>
dan__: great, nice work!
14:15
denial => probably "negation" is a better term in english
14:15
<dan__>
Thanks!
14:15
Yeah I suppose so
14:17
Fixed
