| 09:56 | <danboid> Mornink
| |
| 09:56 | 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...
| |
| 10:19 | vsuojanen 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?
| |
| 10:21 | vsuojanen 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

| 12:44 | <dan__> 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
