<alkisg>
Leolo_2: using a dedicated nbd port is deprecated, try to use the new name based method.
03:48
Also, if you want to use a loopback image AND be able to experiment on top of it, create a new VM with e.g. virtualbox, select static image, not dynamic, and then work on snapshots on top of that
03:48
The "ltsp-update-image" equivalent then will be "merge snapshot"
03:48
...which only takes a couple of seconds
03:49
btrfs allows for snapshots within the image itself, that's why I was experimenting on it

<laro>
hi everyone :)
07:54
<alkisg>
Hello
07:54
<laro>
Today I have a question about "shared folders", I mean by that a folder in the ltsp-pnp server that any user can access
07:54
hey alkisg ;)
07:55
everything is working smoothly here, installed the tp-link sg-1024de as you suggested
07:55
<alkisg>
Do you know about LOCALAPPS_EXTRA_MOUNTS?
07:55
<laro>
I was reading this https://lists.debian.org/debian-edu/2016/02/msg00005.html
07:55
<alkisg>
err, typo, LOCAL_APPS_EXTRAMOUNTS
07:55
<laro>
and it mentions it, but I didn't if I had to do the same but in /var/lib/tftpboot/ltsp/i386/lts.conf
07:56
*didn't know
07:56
<alkisg>
Yes, the correct lts.conf path is in tftp, not in opt
07:58
<laro>
so I create a folder in the server and edit lts.conf right?
07:59
<alkisg>
Yes, e.g. /home/Shared, and make sure it's there in the chroot as well
08:03
<laro>
ok I'm gonna try that
08:03
Do I need to restart the server? or just the clients?
08:03
<alkisg>
Only the client
08:04
<laro>
Is it safe to update the system? because last time it messed up with my interfaces set up, I guess you remember XD
08:08
<alkisg>
Sorry I don't remember, can you remind me?
08:08
In general it's safe to run ubuntu upgrades (it's unrelated to ltsp),
08:08
<laro>
Yes, I am using ubuntu mate 16.04 with ltsp-pnp
08:08
<alkisg>
but of course there's always a risk; I've seen newer kernels not booting with the same hardware, graphics drivers issues, filesystem issues etc
08:09
<laro>
And last time some update messed with interfaces, I think, You had to vnc and fix it
08:09
<alkisg>
I remember the vnc, but I don't remember what issue it was
08:11
<laro>
root@servidor-ltsp:~# cd /etc/network/if-up.d/ root@servidor-ltsp:/etc/network/if-up.d# mv /tmp/sch-scripts.if-up sch-scripts root@servidor-ltsp:/etc/network/if-up.d# chmod +x sch-scripts root@servidor-ltsp:/etc/network/if-up.d# ip a
08:11
something like that I think
08:12
<alkisg>
Do you have a 2-nic setup?
08:13
<laro>
Yes
08:13
<alkisg>
That script solves the flow control issue and adds automatic nat support. It's not related to issues caused by updates.
08:14
I.e. that indeed fixed a problem, but not a problem caused by updates
08:14
<laro>
13:08 <alkisg> laro: your dnsmasq needed restarting because of stupid ubuntu patches
08:14
I found the log haha, it was dnsmasq
08:15
<alkisg>
Again not related to updates though
08:16
<laro>
oh ok
08:16
thought patches were related to updates
08:17
<alkisg>
The issue was this: ubuntu puts dnsmasq in a special mode called "bind-interfaces". This "patch" has been added a few years ago.
08:17
<laro>
13:11 If you're keeping notes, the main issue was "bind-interfaces" in /etc/dnsmasq.d/network-manager 13:11 I'll add that to the wiki, if I don't have it already...
08:17
<alkisg>
But dnsmasq doesn't work well that way, and some times it hangs and it needs to be restarted
08:17
So for ltsp, it's best if we remove the stupid ubuntu "bind-interfaces" option
08:18
<laro>
ok I understand it
08:18
now
08:18
<alkisg>
So it wasn't caused by updates. You always had this issue, it just appears randomly, e.g. 1 out of 100 times
08:19
<laro>
so I was just being unlucky
08:19
<alkisg>
Yes, a reboot would have fixed it
08:19
<laro>
shared folder is working, btw, thanks again
08:20
<alkisg>
np :)
08:20
<laro>
ok, because of that "magic" you did, I was afraid to touch anything haha, newbie issues

I get as far as the swapon and then it hangs
22:49
