[05:35] [_UsUrPeR_] morning all
[05:37] [vvinet] good morning
[05:39] [_UsUrPeR_] I'm trying to figure out how to get all the open office variations (word processor, spreadsheet, etc...) to be known by the server/client as localapps. Right now, I have "ooffice" under LOCAL_APPS_MENU_ITEMS, but it's not creating an xprop command for OOo.
[05:40] [_UsUrPeR_] I have realized that instead of separate office executables, openoffice is opened by the same executable along with an option (i.e. -calc, -write, etc...) is anybody familiar with getting the menu items working?
[05:43] [alkisg] _UsUrPeR_: are you looking for the "normal" way, i.e. by opening them from the gnome menus, or are you looking for something special, e.g. a command line way?
[05:43] [alkisg] Because for the "normal" way you just need to enable the local apps menu, you don't need to speficy any items...
[05:44] [alkisg] LOCAL_APPS_MENU=True
[06:22] [highvoltage] hey alkisg
[06:23] [alkisg] Hi highvoltage
[06:23] [highvoltage] alkisg: since you're always on top of things, have you tested ltsp installation with the new ldm-server package and have you had it hang on installation again?
[06:23] [highvoltage] alkisg: mine still does and I have the newest package, which is weird.
[06:24] [alkisg] highvoltage: no, this week I'm programming an inetd-based bash server & a bash client to remote control ltsp clients, so I haven't tried anything new
[06:25] [highvoltage] alkisg: sounds like fun :)
[06:25] vbundi (~vbundi@d204-191-8-43.abhsia.telus.net) left irc: Quit: Leaving
[06:25] [alkisg] highvoltage: if it succeeds, I'll have no more use for italc, tcm, controlaula etc :)
[06:25] *** alkisg is able to send text commands and receive text output both on thin + fat clients, and is working on getting binary data e.g. for screenshots..
[06:26] [alkisg] highvoltage: but do comment your experience on the bug report...
[06:31] [highvoltage] alkisg: yep! will try out. do you implement ssl as well?
[06:31] [alkisg] highvoltage: no, it's working over the existing ssh connection
[06:31] [alkisg] So no need for authorization / encryption or whatever
[06:31] [alkisg] (that's for fat clients)
[06:31] [highvoltage] alkisg: ah ok
[06:31] [alkisg] For thin clients, it's working directly on the server, so again no encryption is necessary
[06:32] [alkisg] ..and as a side-effect, I get automatic notifications of when clients boot / users logon / logoff etc...
[06:32] [alkisg] The client is just a bash script, so it can run in 64mb as well.
[06:33] [highvoltage] alkisg: nice
[06:33] [highvoltage] alkisg: do you plan to make it something that could be included by default in ltsp one day?
[06:34] [alkisg] I'm trying to, e.g. I put lts.conf variables for clients that one might not want to control etc,
[06:35] [alkisg] but for Lucid it's just going to be part of my "sch-scripts" project, which due to time constrains is greek only,
[06:35] [alkisg] ...but I'd like to internationalize it in the summer, if any native english speaker is interested on proofreading it
[06:47] [alkisg] Yey! Binary transfers working :)

[07:41] [alkisg] highvoltage, and anyone else that might be interested: I have two scripts ready, `sch-server` which runs from inetd on the ltsp server, and `sch-client` which runs both on the thin client as root and on the user session from /etc/xdg/autostart.
[07:41] [alkisg] Now I'm creating the third and final script, `sch-send`, which will be used by the sysadmin to send commands to the clients and/or users, and I'd like some feedback on what its parameters should be.
[07:41] [alkisg] I'm thinking: sch-send [-h] hostname | [-u] username | [-i] ip | [-m] mac-address command [params]
[07:41] [alkisg] E.g. `sch-send ltsp123 poweroff`, or `sch-send ltsp123 firefox`.
[07:41] [alkisg] The problem is that `poweroff` should be executed by the root sch-client (daemon), while `firefox` should be executed by the user sch-client.
[07:41] [alkisg] So in order for that simple syntax to work, I'd need to list some specific commands (get-client-info, poweroff, reboot), to be executed by root, while all the others by the user sch-client. Is that acceptable? Any other commands that you'd need to run as roots on the clients?
[07:44] [alkisg] (and alternative would for an additional [-r] parameter that would specify that the command should be executed by the root daemon)

[10:11] [alkisg] So far it seems stable; I transfered a whole .iso without problems
[10:12] [alkisg] I think I'll have the framework ready in 2-3 days, so if anyone wants to package it separately from sch-scripts, it'll be very nice

[11:23] [vaix] is there CentOS integration on LTSP server side? Are there any best practices/concerns around using mixed distros? All our linxu servers today are CentOS. We have several stand-alone workstations running ubuntu
[11:24] [Appiah] should be no concerns regards different dists..
[11:24] [Appiah] K12Linux = LTSP on Centos I think
[11:25] [vaix] Appiah: thanks.
[11:26] [vaix] LTSP work in combo w/ LVS - so I can have an HA/DR config for LTSP?
[11:26] [Appiah] I dont know what LVS is
[11:26] [Appiah] and HA/DR either
[11:26] [vaix] LVS = linux virtual server. HA = High Availability, DR = Disaster Recovery
[11:27] [Appiah] LVS , yes
[11:27] [Appiah] HA/DR Well there is ltsp-cluster
[11:27] [Appiah] check that out and how you can put that togheter with your HA config today

[12:57] [vaix] perhaps I am dense... but is there a way to get LTSP w/out using the ISO ditributions? Can I download the source and compile/configure directly? Are RPM/deb files available?
[12:58] [alkisg] What .iso distributions?
[12:59] din_os (~k@ppp-94-65-169-239.home.otenet.gr) joined #ltsp.
[12:59] [alkisg] E.g. in ubuntu you can get it with apt-get install ltsp-server, or apt-get source ltsp-server if you want the source, or aptitude download ltsp-server if you want the .deb...
[12:59] arauto (~leandro@187.20.24.211) joined #ltsp.
[12:59] [vagrantc] vaix: yes, you can install debian, ubuntu or fedora and then install the ltsp-server packages and then use ltsp-build-client to build the ltsp environment
[13:00] din_os (~k@ppp-94-65-169-239.home.otenet.gr) left irc: Client Quit
[13:00] [alkisg] vagrantc: does debian support tcp sockets in bash? E.g. exec 3<>/dev/tcp/localhost/22 ?
[13:01] [vagrantc] alkisg: i think i played with that back in 2001...
[13:01] [vagrantc] so i'm guessing so
[13:01] [alkisg] vagrantc: I got 3 scripts almost ready, 2 in bash and one in python, to send commands to ltsp clients
[13:01] [alkisg] They reuse the ssh channel to transfer the commands
[13:02] [alkisg] Do you think they'd belong upstream, given enough care of course?
[13:02] [alkisg] The server script uses openbsd-inet + bash
[13:03] [alkisg] The client script only bash ==> works in 64 MB ram clients,
[13:03] [vagrantc] possibly...
[13:03] [alkisg] and the command-send script python, so that it can be used as a module
[13:04] [alkisg] Right now I'm tailoring them to my needs, but if there's a possibility to get them upstream, maybe I should give them more generic names... (e.g. now I'm calling them sch-server, sch-client and sch-send...)
[13:04] [alkisg] http://bazaar.launchpad.net/~sch-devs/sch-scripts/trunk/revision/109
[13:05] [vagrantc] alkisg: and what sorts of things are you planning on doing with them that couldn't be done easily before?
[13:05] [alkisg] vagrantc: in /var/run/sch-server/* I have a list of sockets with mac/ip/user/host, so I can easily detect which user/host is on
[13:05] [vagrantc] oooh.
[13:05] [alkisg] I can send a poweroff to the clients or run cron jobs on them from the server
[13:06] [alkisg] (no authentication needed)
[13:06] [alkisg] I can send commands to the user sessions, be it on thin or fat clients
[13:06] [vagrantc] a restricted (or restrictable) set of commands?
[13:06] [alkisg] E.g. "sch-send user123 firefox"
[13:06] [vagrantc] sounds pretty cool.
[13:06] [alkisg] The root commands are restricted currently
[13:06] [alkisg] (to poweroff, reboot, exit and sch-info)
[13:06] [alkisg] The user commands are not restricted on purpose
[13:07] [alkisg] The root commands are unencrypted, but they're using reverse connections, so they cannot be easily exploited
[13:07] [alkisg] The user commands use the ssh channel, so they're encrypted
[13:07] [vagrantc] unencrrypted?
[13:07] [alkisg] poweroff/reboot => do they need encryption?
[13:08] [vagrantc] just curious how you implement them unencrypted if the communication channel is already encrypted
[13:08] [alkisg] There are 2 daemons per terminal, one that runs as root (always), and one that runs inside the user session
[13:08] [alkisg] The one that runs as root is executed before ldm starts
[13:08] [alkisg] So it connects to server:9570 on an unencrypted channel
[13:09] [vagrantc] ah.
[13:09] [alkisg] The other one is using ssh port forwarding, so it uses encryption
[13:09] [vagrantc] got it
[13:09] [Gadi] sounds like a system bus and a session bus
[13:09] [alkisg] (and connects to the same port)
[13:09] [Gadi] :)
[13:09] [alkisg] Each connection is only using one bash on the clients, so it needs minimum ram
[13:10] [alkisg] And I've already started implementing some lts.conf options for not starting some of them...
[13:10] [alkisg] (e.g. we might not want to run them in some hosts)
[13:11] [alkisg] If you guys are interested, I should change the names to more generic ones, get rid of the sch-* prefix
[13:11] [alkisg] ...and we'll see in the future if it's worth to be put upstream.
[13:12] [alkisg] Gadi, right, nice metaphor :)
[13:13] [Gadi] just something I was doodling on the side of my notebook while the professor waas teaching ;)
[13:14] *** Gadi cheers alkisg on - and hopes he doesn't get sidetracked from this effort when people start talking about tubes and dbus over ssh and unicrons and all the other "correct" approaches to things
[13:14] [Gadi] :)
[13:14] [Gadi] *unicorns
[13:15] [alkisg] Gadi, I've wasted 2 weeks on those :)
[13:15] [vagrantc] the one true cron
[13:15] [alkisg] ...and another one on twisted :)
[13:15] [vagrantc] twisted?
[13:15] *** vagrantc cringes
[13:16] [alkisg] BASH_ROCKS!
[13:16] [Gadi] Linux is a bizarre beast aint it? I mean what other OS can you have a twisted gimp talking to an oaf through a tube on dbus?
[13:16] [Gadi] honestly
[13:16] [alkisg] Hehe
[13:16] [Gadi] it just sounds ridiculous
[13:17] [vagrantc] next hackfefst, we should play illuminati
[13:17] [Gadi] I'm waiting to sweep the nation with a project called Poopie
