<JdGordon>
I think I have my lstp server set up correctly, but I have my router for dhcp and dont want to use the ltsp for it. Can someone point me to how to get it to boot once it gets an ip from the router?

<PMantis>
Hey guys
13:11
<jammcq>
hey PMantis
13:11
<PMantis>
jammcq, I need to write a (perl?) program to telnet into Asterisk Manager, login, and listed for events, then UDP broadcast them to the network... any pointers?
13:11
errr s/listed/listen/
13:13* jammcq thinks there's already hooks in Asterisk for that sort of thing
13:13* PMantis not sure where to begin... but I think this would be a good opportunity to learn more perl.
13:13
<jammcq>
using the telnet protocol would be kind of a backwards way of doing it
13:14
<PMantis>
I don't think that kind of support is there. the Management interface is for this sort of thing... which you telnet into, then if events are turned on, you get blasted every event that occurs.
13:14
It would be better to broadcast this information to the network, than to have 30 telnet sessions all requesting the same information.
13:14
<jammcq>
I dissagree
13:15
the management interface is just a client program that uses the same API that you can use to write other clients to talk to the asterisk engine
13:15
<PMantis>
Oh, you disagree to the "support" comment.
13:16
<jammcq>
yes
13:16
<PMantis>
AFAIK, it's built into *
13:16
Hmmm, perhaps I've looked at it wrong.
13:16
I'll have to ask in #asterisk.
13:16
<jammcq>
yeah, but I think the API is there, and there are hooks there to trigger things for you
13:17
it's common to do Perl things in Asterisk
13:18
certainly you could do it with Perl watching the mgmt interface, but then you are screen-scraping the data on the screen, and it becomes very brittle
13:20
<PMantis>
Sure,, AGI can use perl
13:20
<jammcq>
AGI ?
13:20
<PMantis>
Asterisk Gateway Interface.
13:20
<jammcq>
ah
13:20mistik1 has quit IRC
13:20
<PMantis>
Like CGI, but for the * dialplan
13:21
<jammcq>
oh, to construct dial plan rules on the fly ?
13:21
what kind of events are you interested in catching?
13:22
<PMantis>
Not *quite*, but to shell to perl from the dialplan, and with an AGI->blah, you can control the channel from within your native language... perl being a great example.
13:22
The events I need are things like dial, ring.
13:23
Want to have a client program that installs on each computer, and displays the state of the phone that's in the same cubicle.
13:23
Such as play a "ring" wav file when the phone rings... client is used to that with the phone system that's being replaced.
13:24
<jammcq>
hmm

16:14
<tomcats>
has anyone used ltsp over leased bandwith?
16:20* vagrantc modularized the debian ltsp init scripts!
16:24
<tomcats>
vagrantc: u there?
16:25
<vagrantc>
sure.
16:25
<tomcats>
vagrantc: a while back I was having trouble setting up a call center based on ltsp and thin clients...
16:26
the project went well, they have been running for 3 months now and no problems
16:27mistik1 has joined #ltsp
16:27
<tomcats>
at the end we decided to have everything run locally kind of what muekow does
16:28
so basically the server is really just a nfs, nis server
16:29
<jammcq>
for a call center, that's a good way to go
16:29
<vagrantc>
muekow doesn't run everything locally by default
16:29
but it's easier to do that LTSP 4.x
16:29
er, easier to do with muekow than older LTSP versions
16:30
<tomcats>
yes indeed
16:30
<vagrantc>
pwd
16:30
tomcats: so ... you want to switch to LTSP 5.0/muekow or what? :)
16:30
<tomcats>
now what we are trying to figure out is if we could colocate the servers (asterisk + app) in our datacenter..
16:31
this way other people could use the spare cycles of both the cervers and the end-user would have nothing to break...
16:32
<vagrantc>
how do you propose to use these "spare cycles" ?
16:33
<tomcats>
the only way we think we could do this reliably is with leased bandwith, but we never seen a machine boot PXE over HDLC or PPP..
16:33* vagrantc doesn't have any experience doing that
16:33
<tomcats>
vagrantc: I mean the servers and architecture is scalable, meaning other call-centers could run using the same hardware for less$$
16:33
<jammcq>
are you talking about putting the clients in a rack somewhere?
16:33
<tomcats>
jammcq: yes
16:34
<jammcq>
but the monitor, keyboard, mouse and headset would need to be where the user is sitting. How would you connect those things up to a server colocated ?
16:35
<tomcats>
jammcq: sorry, servers --> datacenter clients --> call-center
16:36
<vagrantc>
tomcats: you're going to have a really hard time not having some sort of basic server at each call center.
16:36
<jammcq>
well, keep in mind, if you run the apps locally, you'll be doing a whole lot more NFS traffic. Separating the clients from the servers by a low-speed connection will cause the apps to load VERY slowely
16:38
<tomcats>
jammcq: the idea is to have everything run locally so yes it would take some time to load but from there it should be quick, the only traffic would be g729 voice (~10k/s) and say... a web based CRM...
16:39
vagrantc: why hard time?
16:39
<vagrantc>
tomcats: i suspect it will be totally unworkable.
16:39
tomcats: NFS eats a lot of bandwidth, at least when you're talking non-ethernet.
16:40
tomcats: the startup times may be so slow as to be unuseable- quite possibly getting NFS timeouts.
16:41
tomcats: but feel free to prove us wrong. :P
16:42ogra has quit IRC
16:42
<tomcats>
vagrantc: nfs is not really needed after boot time... and PXE would load the main fs
16:43
<jammcq>
no
16:43
PXE loads the kernel and a very small initramfs
16:43
unless you've created some massive initramfs
16:43
<tomcats>
bingo
16:43
<jammcq>
how big is your initramfs ?
16:44
<vagrantc>
you probably want something like PXES or something, for that.

16:47
<tomcats>
i think that 64 mb should be enough to load a basic window manager, firefox and softphone
16:47
<jammcq>
tomcats: umm, good luck
16:47
it *might* be possible
16:47
<cliebow_>
tomcats:in muekow or 4.2
16:48* vagrantc remains skeptical
16:48* vagrantc suspects neither
16:48
<jammcq>
well, some of the coolest things out there are a result of someone saying it can't be done
16:48
<cliebow_>
yeah..take me for instance
16:48
<tomcats>
it can't be impossible...
16:50
plus the cost of bandwith vs. an IT department should be substancial...
16:50
<vagrantc>
tomcats: when you've said 64MB, unless you have very loose interpretations of wha firefox is, it very well might be impossible.
16:50
but no use convincing the skeptic with words :P
16:51
<jammcq>
well, firefox 1.5 on my server takes 30mb
16:51ogra has joined #ltsp
16:51* vagrantc will continue to do work and not discuss theories about what is and isn't possible.
16:51
<jammcq>
although the current LTSP-4.2 tree is about 120mb
16:51
and that's without firefox
16:52
<vagrantc>
right.
16:52
<tomcats>
devonit does it qith 128 DOM module and 256 of ram...
16:52
<jammcq>
there's alot of stuff in the ltsp tree that wouldn't be needed
16:52
<vagrantc>
i think PXES had images aroung 70MB, without anything running locally.
16:52
other than X

isn't dsl smaller than 50mb?
16:53
<jammcq>
does that include X ?
16:53
<vagrantc>
yes.
16:54
but not firefox, i don't think.
16:54
they use a lot of hacks and really old software, though.
16:54
<cliebow_>
dillo?
16:55
<tomcats>
vagrantc: yes,according to webpage DSL includes firefox
16:55
<vagrantc>
well i'll be.
16:55
<tomcats>
lol
16:56
<vagrantc>
tomcats: have at it
16:56
tomcats: probably your best bet is to just serve up DSL images or something.
16:56robbie has joined #ltsp
16:56
<vagrantc>
i wouldn't want to take all the time to re-implement the hacks they've done.
16:57
<tomcats>
you are right that was kind of the lead we were loking at, there is also several hacks of knoppix that could work as a base

these melug guys are all fired up abut it..makes gentoo look like a windows install
18:47
<jammcq>
umm, is that supposed to be a good thing?
18:47
<cliebow>
im going down to se them on Saturday..see if they arer interested in muekow
18:47
<jammcq>
we've already got dberkholz working on that
18:47
if they are interested, they should coordinate with him
18:48* vagrantc puts a sticker on the bicycle "I HEART pre-built binaries"
18:48
<cliebow>
this is even barer metal then gentoo..but semm to be some talented people working on sourcemage
18:48
here
18:49
<vagrantc>
basically, the portage equivalent is written in shell instead of python.
18:49
<cliebow>
vagrantc:you mean in gentoo?
18:49
<vagrantc>
cliebow: no, in sourcemage.
18:49
<cliebow>
ahhh
18:49
<vagrantc>
cliebow: in gentoo the package manager is written in python, i think. in sourcemage, i think it's shell.

18:50
<vagrantc>
i remember trying to read documentation for sourcemage a few years back, and i was convinced they were trying to make it harder to use by developing an elaborate spellcasting analogy :)
18:51
at least they didn't write all the commands in latin or something.
18:51
<cliebow>
well should be interesting..they dont seem to know squat about ltsp
18:52
vagrantc:Haaa..i see what you mena
