Hi ogra! Do you happen to know if there were any changes in "how to prevent snap from auto-updating" in the past year or so?
06:59
In https://github.com/ltsp/ltsp/blob/main/ltsp/client/init/55-snap.sh I had adapted code from casper, but some people recently reported that snap was downloading updates on ltsp clients anyway, exhausting their RAM...

alkisg, snapd only allows holding back updates for max 60 days ... with firefox becoming a default snap in desktop i expect https://forum.snapcraft.io/t/wip-refresh-app-awareness/10736 to also be set by default soon though ... that will make sure to not update currently running snaps and notify you to please close and update it manually
13:34
(the same 60 days limit applies though ... after these are over snapd will force an update)
13:35
the casper hack is really just that ... a hack ...
13:57
<alkisg>
Heh, more good news about ltsp :D
13:57
There should really be an off switch, for things like live cds or ltsp...
14:04
<ogra>
well, for livecds the assumption is that you dont run them for 60 days usually ...
14:05
the refresh-app-awareness setting is pretty nice thogh ... not much different from the in-app notification firefox gives you for updates
15:36
<brcisna[m]>
alkisg, This is an odd scenario,just curious if this would be possible with ltsp. Would it be possible to set the dnsmasq settings that are generated by ltsp build into a libvirtd virnet config file?
15:36
Reason asking: Assumed a cellular connection as internet access. This only allows for one connected device. Have messed with iptables rules until im blue in the face. After i connect more than one device along with server the modem starts disconnecting. (Thought i was having problems with modem but was the fact only one net connection allowed) If i setup a couple hard drive machines inside of kvm/qemu and start them they will all allow
15:36
continuous connections. The NAT forwarding in libvirtd must have the glue to not appear as another machine? Sounds like a goofy idea , i know. Sorry for long post. Thanks Barry
15:37
<alkisg>
ogra: but you can run a live cd that is itself 60 days or 2 years old, right?
15:37
So its snaps may be more than a year old...
15:38
brcisna: I don't use libvirtd so I'm fuzzy on the details; but if you set up your ltsp server ethernet NIC to 192.168.67.1, it automatically does NAT to your internet connection
15:39
So, ethernet = 192.168.67.1, and internet comes from cellular connection => it will only see one IP, everything should automatically work
15:41
<brcisna[m]>
Ok thank You,,Thank You,,alkis,,I will set nic to 192.168.67.1 !! I am still stuck on the default ips ltsp used 15 years ago,is like 172.31.100.0 ! :) will report on this ina aday! You are always good help.
15:43
<alkisg>
Note that in 192.168.67.1, it also does REAL dhcp, not proxy dhcp
15:43
So then you should disable any other dhcp servers you have
15:44
<brcisna[m]>
alkisg , I only have the default dnsmasq server going.. have never added any other dhcp items/packages.
15:45
<alkisg>
Where do your clients get the IP from? E.g. in my setup, they get it from the router
15:46
<brcisna[m]>
i set the dnsmasq settings for dhcp-range= eth0,172.31.100.50,172.31.100.250
15:47
when the ltsp-dnsmasq it did see the isp dhcp range to proxy,,i commnetd this out,,,probably shouldnt have?
15:47
<alkisg>
OK then just run this:
15:48
ltsp dnsmasq
15:48
No parameters involved. Then set your server IP to 192.168.67.1
15:48
<brcisna[m]>
ok thanks,,will do tonight,,,thansk a million!
