<danboid>
No alkisg?
13:19
It's not possible to use LTSP fat clients over the internet is it? I know you could still kinda use the server via x2go or VNC etc but that's no longer LTSP
13:20
I remember alkisg had some kind of solution in place for these situations but I don't remember what
13:21
highvoltage, ^^
13:30
<alkisg>
Hey danboid
13:30
You want to netboot over the internet?
13:30
How fast is your internet?
13:32
Are you sure you don't want to cache the ltsp image locally in the target lan?
13:32
<danboid>
I think its 100 Mb/s up at the DC where our LTSP server lives
13:33
<alkisg>
Anyway, there's no "LAN" restriction in any phase of an ltsp client boot, except for dhcp
13:33
<danboid>
The LAN is gigabit
13:33
<alkisg>
You can overcome the dhcp part if you use ipxe
13:33
If you have the ability to use even a raspberry pi there as a dhcp/image server, it would make things a lot faster
13:34
Even if login + /home are over the internet
13:35
If you want better advice, describe the use case in more detail
13:35
<danboid>
Yes, I asking about internet netboot. It can be done with ipxe you say?
13:35
<alkisg>
Sure, there's no restriction for tftp, nfs, sshfs, ssh etc that says you need to use lan
13:35
Only dhcp uses ethernet packets instead of ip packets, so you need ipxe to overcome that part
13:35
<danboid>
Obviously it will be a lot slower than using it on the lan
13:36
<alkisg>
Is it about coronavirus teleworking?
13:36
<danboid>
How did you guess? :)
13:36
<alkisg>
:)
13:36
How many clients, and do you have SSDs in them?
13:37
<danboid>
Why do you ask about SSDs?
13:37
<alkisg>
Because it would allow you to cache the image there, and make things a lot faster, and put ipxe as well
13:38
(actually, grub in that case, not ipxe)
13:41
<danboid>
I think the envisioned scenario is that we'd like students to be able to stick a bootable ipxe USB drive into their laptops/desktops and boot into a fat client. Most will not have a Rpi available and I don;t want to presume they have any kind of disk or OS installed
13:42
Obvs they will but it could be a Mac, Linux or Windows machine with any kind of disk
13:42
<alkisg>
OK, see, you gave more info :)
13:42
Instead of putting ipxe in the usb stick, you could put the ltsp image, and make things a lot faster
13:43
But if you want to avoid that, sure; experience teaches better than irc advice :)
13:44
It's also possible to cache the image in any disk that already has an OS, but if you don't want to go there, understandable
13:44
<danboid>
I never considered putting the image on a USB. That's a good idea but then again we do update it frequently
13:45
<alkisg>
Depending on some things, updating the image over the internet automatically could again be faster than netbooting
13:45
<danboid>
So with the caching, it would be able to check if the LTSP server has a newer image and if it does, it downloads that?
13:46
<alkisg>
Yeah; and it's possible to either "wait until it's done", or "use the available image, and prompt for reboot when the new has finished downloading"
13:46
A bit of scripting would be needed in either case, it's not automated
13:50
Additionally, wireguard could be used to implement a low-level VPN and make things safer for everyone
13:51
Finally, it's also possible to instruct users to use virtualbox and netboot an LTSP fat client inside their OS. But this requires that they have hardware virtualization and enough RAM.
13:52
<danboid>
OK great. There are more options than I thought then
