| 03:47 | <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

| 07:53 | <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
