| 17:37 | <Leandro_> Hello guys. I'm currently trying to run an ltsp server over ubuntu-mate-amd64-18.04. I need both 32 and 64bits clients to be able to run, so I have a chroot-less amd64 running well, and made a chroot i386 build. The problem is that when I try to login the i386 client, I get hte following message on client screen: Error: Unknown error in reply to NBD_OPT_GO; cannot continue. Then I drop to a initramfs prompt.

| 17:38 | <Leandro_> What config file should be helpful for me to share?
| |
| 17:38 | <alkisg> Leandro_: that's just a misconfiguration on nbd-server or dnsmasq
| |
| 17:38 | <vagrantc> check the logs on the server, maybe it's getting the wrong NBD image
| |
| 17:39 | <alkisg> Are you sure that a single 32bit installation isn't best for you?
| |
| 17:39 | How much RAM does your server or your best client have?
| |
| 17:40 | adrianorg has left IRC (adrianorg!~adrianorg@177.156.224.28, Ping timeout: 246 seconds) | |
| 17:40 | <Leandro_> The RAM on my server is not really and issue. But my clients are some old 4GB RAM All-in-one, that are able to run 64-bits, but I have also some old HP thin-clients, that I think have only 512MB RAM and are only 32-bits
| |
| 17:41 | <alkisg> Leandro_: 32bit installations have problems with much ram, so the server ram is an issue, if it's over 8gb
| |
| 17:41 | the 4gb clients will function about the same with 32 or 64bit
| |
| 17:41 | So if you have <=8 gb ram on the server, I would go for a single 32bit installation
| |
| 17:42 | Much easier to maintain, with no real drawbacks in this scenario
| |
| 17:42 | My second choice would be a 32bit installation with an additional 64bit kernel for the server
| |
| 17:43 | The dual chrootless/chroot setup would be 3rd or lower choice...
| |
| 17:44 | <Leandro_> Could you elaborate a little bit on your second choice please?
| |
| 17:44 | <alkisg> Could you mention your server ram?
| |
| 17:44 | It will make the chat easier
| |
| 17:45 | So the idea is, you install/maintain a 32bit chrootless setup. The clients perform fine. The drawbacks are: some apps like e.g. viber are 64-bit only,
| |
| 17:46 | <Leandro_> Sure, I have between 4GB, up to 8GB if necessary. It is a VM.
| |
| 17:46 | <alkisg> and, there's a bug where if you have 32bit and e.g. 10+ GB RAM, the *disk* performance is 100 times slower
| |
| 17:46 | <highvoltage> alkisg: ah I haven't considered that one... interesting
| |
| 17:46 | <alkisg> So, in cases where the server ram is 10+ gb, we install a 64bit kernel
| |
| 17:46 | so that the server disk access remains fast, i.e. it doesn't hit that bug
| |
| 17:47 | <vagrantc> !pae
| |
| 17:47 | <ltsp> I do not know about 'pae', but I do know about these similar topics: 'non-pae'
| |
| 17:47 | <alkisg> So in your case, you'd just go with 32bit chrootless and nothing more
| |
| 17:47 | <vagrantc> that's a really annoying bug that will probably never get fixed :(
| |
| 17:47 | <alkisg> You don't need 64bit, you don't need two kernels
| |
| 17:47 | <vagrantc> since most development has moved on to 64bit...
| |
| 17:48 | <alkisg> Yeah. I do think it makes 64bit hard disk access 2-3 times slower, but noone has cared enough now to solve it, with SSDs and all
| |
| 17:48 | I hope some time in the future I'll see a phoronix article "developer solves 10 year old issue, making disk access 2-3 times faster" :D
| |
| 17:49 | (i mean, it affects 64bit too, but a lot less than 32bit)
| |
| 17:49 | <vagrantc> oh, didn't know it caused issues on 64bit
| |
| 17:49 | (even if more hidden)

| 17:55 | <Leandro_> Sorry, my ISP went down
| |
| 17:55 | Could please forward your last messages again?

| 17:56 | <ltsp> logs: http://irclogs.ltsp.org/
| |
| 17:58 | <Leandro_> Thank you. I will go with your solution where I use only 32-bits image. I don't think I'll need much more applications other than the stock ones ubuntu provides.
| |
| 17:58 | Thanks a lot alkisg.
| |
| 17:58 | <alkisg> You're welcome

| 18:41 | <||cw> size = 202223351MBErrir: Exported device is too big get a 64-bit machine
| |
| 18:41 | I have a 64bit machine in this case, but will have 32bit ones, so i have a 32bit kernel and 32bit server
| |
| 18:42 | the img file is 1.5GB though, so what happened here?
| |
| 18:42 | <alkisg> ||cw: that usually means wrong path, broken symlinks for the image etc
| |
| 18:43 | Those nbd errors are really cryptic :)
| |
| 18:43 | Check the path mentioned in ltsp_amd64.conf vs the real image path in the disk
| |
| 18:45 | <||cw> path is fine
| |
| 18:48 | does ndb not put anything in syslog?
| |
| 18:56 | ok I found the issue. my dhcp/pxe is doing it, it's connecting to the wrong server. it also doens't seem to be downloading lts.conf from tftp

| 20:12 | <epoptes_user3> Hello. I have debian stretch installed and epoptes 0.5 that work fine except for full screen broadcast. How can i install the version one of epoptes without using the ubuntu ppa repository (ts_sch_gr-ubuntu-ppa-disco)? Thanks.
| |
| 20:13 | <vagrantc> hmmm...
| |
| 20:14 | i could try and backport it to stretch to make it available via stretch-backports
| |
| 20:14 | but the next release of debian is coming out soon, so not sure how much free time i have for it
| |
| 20:15 | really need to spend some more time testing the next release of ltsp...
| |
| 20:15 | er, debian
| |
| 20:16 | epoptes_user3: you might be able to just install one of the alternate vnc viewers, the default installed with epoptes on debian might lack some features ...
| |
| 20:19 | oh, it switched to python3 ... that might be hard to backport
| |
| 20:20 | if the appropriate python3 dependencies aren't available in stretch, it would be a large project
| |
| 20:23 | <epoptes_user3> OK i understand that i will have to wait for next stretch update. Efcaristo poly (merci beaucoup)
| |
| 20:24 | <vagrantc> no, it most likely will never end up in stretch
| |
| 20:24 | will have to wait till buster
| |
| 20:25 | which is hopefully not *too* long
