<derick_>
if ltsp server is providing dhcp services. what can be done to avoid its services to conflict when dhcp services of router?
18:14
<||cw>
derick_: only if it's on its own network
18:14
as in the 2 interfaces examples
18:15
otherwise, configure your router to hand out the PXE related options instead, or turn off your router's dhcp
18:16
or maybe use proxydhcp on the ltsp
18:16
https://help.ubuntu.com/community/UbuntuLTSP/ProxyDHCP
18:17
hm, that might be old, but should be similar
18:18
<derick_>
okay. So if the second interface is in different network(when router is as well), And first interface in network where ltsp is providing dhcp services.
18:18
The setup will work?
18:19
<||cw>
yeah. though http://wiki.ltsp.org/wiki/Installation/Ubuntu implies proxy should work out of the box
18:21
<derick_>
cool. One more question. what is chrootless? I read the docs but I did not understood it.
18:21
I mean in both setup image is created. That is used by ltsp client to boot from.
18:21
<||cw>
it builds image from the server's root, excluding and modifying files as needed on the fly
18:22
great for a mixed fat/thin env as it leave both the same with only one OS install to manage
18:25
<derick_>
okay nice. But see in Installing LTSP in "chroot" mode we use `ltsp-build-client` to create image.
18:25
In Installing LTSP in "chrootless" we use `ltsp-update-image --cleanup /` to again create the image.
18:26
what is the difference then?
18:28
<||cw>
once you have a chroot configured, you also only use ltsp-update-image ot make a new image from it
18:29
<derick_>
And we cannot do that in `chrootless`. Okay. Wow. thanks for clearing me doubt :)
18:30
<||cw>
?
18:30
no
18:31
ltsp-update-image make a new image from a source, chrot or root doesn't matter
18:31
ltsp-build-client make a a new chroot from nothing
18:32
<derick_>
ohh. okay.
18:32
<||cw>
you only run ltsp-build-client once ever, typically

I have created a 2 interface non proxy ltsp setup. But internet does not work on the clients.
19:50
<||cw>
if they are fat clients, you need to make your server a router as well.
19:50
which might be as simple as enabling ip fwd and setup up an appropriate static route on your router
19:51
2-interface is more common for thin clients.
19:53
<derick_>
okay. I will enable ip fwd.
19:57
<||cw>
don't forget the routes. otherwise nothing will know how to get back
19:58
honestly, going single interface and not using the router's DHCP is the best thing in the world. bonus is you get a proper DNS server on your lan
