<Guest62834>
hi there -- running Ubuntu Mate LTSP server; looking for help on fat client /etc/hosts
05:12
i see by design that it gets overwritten at boot time, but i would like a handful of entries for local server resources
05:13Guest62834 is now known as gatorparrots
05:14
<gatorparrots>
i saw one listserv message indicating that in lts.conf, there is an undocumented option for HOST_XX entries for this purpose

05:22Freejack has joined IRC (Freejack!~Freejack@unaffiliated/freejack)
05:26
<gatorparrots>
thus far tried setting those entries in lts.conf
05:26
and an rc.local script that echoes entries into /etc/hosts
06:13
should i look toward installing dnsmasq for local dns? it's really only for a single hosts entry, but 2-3 more would be nice to have

<alkisg>
gatorparrots: dnsmasq would help in speeding up things
06:26
gatorparrots: are you sure your lts.conf gets parsed?
06:27
Put its contents to pastebin

epoptes: Epoptes is a computer lab administration and monitoring tool. It works on Ubuntu and Debian based labs with LTSP or non-LTSP servers, thin and fat clients, standalone workstations, NX clients etc. More info: http://www.epoptes.org
06:30
<alkisg>
Epoptes helps a lot in testing things, it allows you for example to run this on the client:
06:30
getltscfg -a
06:31
..and see if lts.conf gets properly parsed there

07:16
<gatorparrots>
lts.conf is for sure parsed -- i had DNS_SERVER as 192.168.1.1 (router), but it was letting pr0n through, even though the DNS servers on the router are set to use filtering DNS
07:17
<alkisg>
OK, put your lts.conf to pastebin
07:17
<gatorparrots>
so i changed the lts.conf to read "DNS_SERVERS 199.85.126.20 199.85.127.20" aka Norton ConnectSafe DNS and now the blocks are in place
07:19
do you have a syntax for lts.conf host entries? or was that a listserv myth?
07:23
http://pastebin.com/tUDNv04p
07:25
Here is the listserv message to which i refer: https://sourceforge.net/p/ltsp/mailman/message/34093808/
07:28
(i'm a good friend of bennabiy's — he helped us set up this lab)
07:30
okay, so i just figured it out: HOSTS_01="192.168.1.10 server server.tld"
07:30
HOSTS_02="192.168.1.11 anotherhost anotherhost.tld"
07:34
boy do i wish that was documented somewhere! except for that one listserv mention, i wouldn't have ever thought to try that syntax in lts.conf !

<alkisg>
gatorparrots: I don't see any HOSTS in that paste
07:56
Ah, you figured it out, ok
07:56
Also, your RCFILE syntax is wrong
07:57
See the correct syntax there: http://www.epoptes.org/documentation/fat-clients

<alkisg>
Welcome :D
11:31
<sruli>
alkisg: i cannot seem to find anywhere on epoptes.org documentation for openssl, where do i need to look?
11:31
<alkisg>
It's not documented, it's inside the code
11:31
It's using openssl by default for the client connections,
11:31
but I don't think it's using it for the assist function... let me check...
11:31
<sruli>
alkisg: ok, so on github, the default install uses openssl?
11:32
<alkisg>
Yes, but only for part of the functionality
11:32
It's also in ubuntu, you don't need to compile it or anything
11:32
just apt-get install
11:33
<sruli>
alkisg: but for scoat and vnc does it use openssl by default?
11:34
alkisg: or is that something i can adjust easliy in config files?
11:34
<alkisg>
It's using openssl with socat, but not for the task you want,
11:34
See this: http://bazaar.launchpad.net/~epoptes/epoptes/trunk/view/head:/debian/epoptes.postinst
11:34
It has the code to generate the certificate etc
11:35
...and this has the client side code for socat/openssl: https://github.com/Epoptes/epoptes/blob/master/epoptes-client/epoptes-client
11:36
So, to do what you want, we should clone that code into another file, which has the vnc/socat reverse connections, this one: https://github.com/Epoptes/epoptes/blob/master/data/client-functions
11:37
So basically only a couple of lines need to be modified
11:37
bbiab
11:49
<sruli>
alkisg: i'm confused... /master/epoptes-client/epoptes-client has the code to generate certificate, what exactly do i need from /debian/epoptes.postinst and where in /master/data/client-functions do i need to put that code?
12:19gdi2k has joined IRC (gdi2k!~gdi2k@210.5.107.2)
12:21
<sruli>
alkisg: you around?
12:38
<alkisg>
sruli: around-ish...
12:38
Your goal is to make epoptes remote assist to run over ssl, or to get the code and run it manually without epoptes?
12:38
<sruli>
alkisg: regarding openssl, i'm confused... /master/epoptes-client/epoptes-client has the code to generate certificate, what exactly do i need from /debian/epoptes.postinst and where in /master/data/client-functions do i need to put that code?
12:42
alkisg: my goal is to make eopoptes run vnc over ssl
12:43
<alkisg>
sruli: you can file a bug report about it,
12:43
!epoptes-bug
12:43
<ltsp`>
Error: "epoptes-bug" is not a valid command.
12:43
<alkisg>
...at launchpad :D,
12:43
and maybe we could implement it in some future release
12:43
I don't have the time right now to do the implementation
12:43
<sruli>
alkisg: ok, but in the meantime is it a simple task to do manually?
12:44
<alkisg>
It shouldn't take more than a few minutes, yes
12:44
<sruli>
alkisg: any chance of a pointer in the right direction?
12:44
<alkisg>
I tried to, in the last sentences before i left
12:45Faith has joined IRC (Faith!~paty_@unaffiliated/faith)

<alkisg>
There are 2 places to read and 1 place to edit
12:45
(edit = client-functions)
12:45
<sruli>
alkisg: as i said i am not to sure what to do with that sentence ;-)
12:46
<alkisg>
The next more specific thing would be to copy/paste the code myself, which i don't have time to do currently... sorry...
12:47
<sruli>
alkisg: what i dont understand is if /epoptes-client/epoptes-client has the code to generate certificate, what am i looking for in /debian/epoptes.postinst?
12:48
<alkisg>
epoptes-client doesn't have code to generate certificate
12:48
it has code to fetch and use certificate
12:52
<sruli>
alkisg: if i already have the cert installed, (socat) all i need is to copy fetch_certificate function and test -n "$need_certificate" && fetch_certificate to /client-functions ?
12:59
alkisg: i posted the issue on github, do you have a donate page?

Heya Scotty :)
16:02
<sbalneav>
How goes, alkisg?
16:02
<alkisg>
...still waiting for the ministry to make up their minds about ltsp, but other than that, all is fine! you? :)
16:03
<sbalneav>
Doing well; a significant portion of my time at work next year has been approved for LTSP and Mate work.
16:04
<alkisg>
Yey!
16:04
I'm planning to deploy ubuntu-mate to schools here on september, so it'll be close enough to your debian-mate :)

mate rocks
