| 17:30 | <RodrigoAlves[m]> Hello, could someone help me?
| |
| 17:31 | is it possible to pxe boot on different networks? Using for example a DDNS?
| |
| 17:32 | i saw something related to this on the ipxe page but i'm not sure

| 18:43 | <vsuojanen[m]> you mean ipxe.org or something else?
| |
| 18:57 | pxe boot wouldn't work without a dhcp boot server near the clients. but when the client boot (firmware) or boot server offered something like ipxe it can do stuff sure. But... what (OS, web page) do you want to offer from The server and why it can't locate in same network?
| |
| 19:01 | <RodrigoAlves[m]> <vsuojanen[m]> "you mean ipxe.org or something..." <- the same, but it's just a question, I don't really know if it's possible
| |
| 19:02 | <vsuojanen[m]> "pxe boot wouldn't work without a..." <- and if i used a router like dhcp is this possible? Like for example make a dhcp proxy for a DDNS or something?
| |
| 19:03 | I need to do it this way because there are several different places using the same server...
| |
| 19:08 | <vsuojanen[m]> I wouldn't recommend boot over routers, especially with ltsp. Ltsp boot server provides normally a OS filesystem for The clients. What places are you having?
| |
| 19:12 | <RodrigoAlves[m]> It's because I can't think of any other way to do it.
| |
| 19:12 | sorry I didn't understand the question
| |
| 19:13 | <vsuojanen[m]> What these client machines in different networks you have need from The server?

| 19:20 | <vsuojanen[m]> LTSP is used in LAN network where the clients are. If there are different networks they need to controlled and routed in network level. E.x dhcp relay on routers/switch
| |
| 19:21 | <alkisg> Do each of these places have gigabit connection to the central ltsp server?
| |
| 19:21 | LTSP does need fast network speed...

| 19:28 | <RodrigoAlves[m]> <vsuojanen[m]> "What these client machines in..." <- are different places, for the same server
| |
| 19:29 | <vsuojanen[m]> "LTSP is used in LAN network..." <- I understood
| |
| 19:31 | <alkisg> "Do each of these places have..." <- Yeah
| |
| 19:31 | <alkisg> "LTSP does need fast network..." <- but how could i make this configuration?
| |
| 19:32 | <vsuojanen[m]> I would think The whole setup first from clients and Their local network. What you need to bring to The network... Not what you need to bring to The server
| |
| 19:34 | <RodrigoAlves[m]> good... the local network is already configured
| |
| 19:41 | <vsuojanen[m]> you want to have just one ltsp client Image to clients which pxe boot in different networks?
| |
| 19:47 | <alkisg> If you have gigabit connections, then just boot them with ipxe
| |
| 19:47 | What are the local DHCP servers like? Are they configurable?
| |
| 19:54 | <RodrigoAlves[m]> <vsuojanen[m]> "you want to have just one ltsp..." <- that the same server
| |
| 19:55 | <alkisg> "What are the local DHCP servers..." <- I'm using ISC DHCP
| |
| 19:59 | What do I need exactly for it to work? Because the image would literally have to go through the internet
| |
| 20:01 | <alkisg> You have isc dhcp on the local networks? (not on the ltsp server lan)
| |
| 20:01 | Then just follow the doc page about it
| |
| 20:02 | <RodrigoAlves[m]> alkisg: no, only on lan of ltsp
| |
| 20:02 | so would i have to have a DHCP at each location?
| |
| 20:03 | <alkisg> How do your clients get IPs?
| |
| 20:03 | Describe the client side lan
| |
| 20:04 | <vsuojanen[m]> pxe boot need DHCP yes.
| |
| 20:05 | <RodrigoAlves[m]> hey I don't know exactly if it works, but I imagined a router with DHCP only and the clients. Or some way to use DDNS
| |
| 20:07 | <alkisg> Rodrigo Alves: can you tell us how your clients get their IPs?
| |
| 20:07 | <vsuojanen[m]> client broadcast to DHCP i need IP and boot server < DHCP IP + boot server
| |
| 20:07 | <alkisg> Do they have configurable routers, or cheap home routers?
| |
| 20:07 | You need to describe your setup to get to a solution
| |
| 20:08 | E.g. tell us "I have remote locations with 10 clients and a XXX model router and a YYY model switch"
| |
| 20:08 | Then we'll be able to advice how to configure the router to point to the ltsp server

| 20:10 | <RodrigoAlves[m]> alkisg: I'm considering using a router with dhcp for the clients. I'm a layman, I don't know if it would work, so I'm asking...
| |
| 20:11 | alkisg: are configurable
| |
| 20:12 | alkisg: oh ok, I'll formulate my question correctly lol
| |
| 20:12 | alkisg: ok, just a moment, i'll try to put as much information as possible
| |
| 20:35 | <alkisg> If the client routers are configurable, you just set next-server to the ltsp server ip
| |
| 20:35 | Anyway it's late here, good night...

| 23:16 | <RodrigoAlves[m]> <RodrigoAlves[m]> "ok, just a moment, i'll try to..." <- the environment is as follows: In the company is the LTSP server, so any client that is started via pxe on the company network will get the server image. The company manages this server for a clinic, this clinic has two branches in nearby cities, and it already has a Windows RDP server running. The idea is to exchange this Windows server for the PXE server that is in the company,
| |
| 23:16 | leaving only the router in the clinics so that clients have access to the outside (WAN). I'm a technical student and I'm just starting in the area, so I don't know much that seems obvious
| |
| 23:18 | > <@alkis:matrix.org> If the client routers are configurable, you just set next-server to the ltsp server ip
| |
| 23:18 | > Anyway it's late here, good night...
| |
| 23:18 | ok, but should I point the router's dhcp client to where? Can I point to a DDNS? Because that way he will have to look for the server on the internet (WAN) right?
| |
| 23:19 | I don't know if I'm missing information, but that's it...
