05:08	<damormino> LTSP on Oneiric (Ubuntu 11.10) is pretty cool. I got it working with Skype, Youtube, pretty much everything. Works just like a Desktop. And both my server and clients are 64-bit.
05:09	Tomorrow I will try 32-bit clients on the same 64-bit server.
05:10	Has anyone seen any major problems on the Oneiric beta that I should look out for?

10:43	markit has joined IRC (markit!~marco@88-149-177-66.staticnet.ngi.it)
10:43	<markit> hi ppl, hi alkisg :) I would love if you could explain clearly to me (like "step by step") how do reverse vnc and ssh to assist school computer, besides what is included in your sch-script (so I can use also for single PC I have at school, or for home pc of teachers), is it possible?
10:43	I could create some basic ruby script for ease this as much as possible, once mastered
10:44	<alkisg> No script needed
10:44	Let's see the shared screen session first:
10:44	<markit> I thought x11vnc was a really slow solution, but I've seen you have been able to assist me with that
10:44	ok
10:44	<alkisg> !socat-screen
10:44	<ltsp> alkisg: socat-screen: to share a local thin client shell with a remote person, see https://help.ubuntu.com/community/UbuntuLTSP/Troubleshooting/socat-screen
10:44	<alkisg> no
10:44	forget that
10:44	!socat
10:44	<ltsp> alkisg: socat: One way to share a console with a remote person is: [local pc] socat tcp-listen:5500,keepalive=1 stdio,raw,echo=0 [remote pc] socat SYSTEM:"sleep 1 && exec screen -xRR ra",pty,stderr tcp:server:5500 & screen -l -S ra
10:44	<alkisg> ^This one
10:45	So, you just need to apt-get install socat screen, to port-forward 5500 in your router (only the local pc, the "technician"), and to run this command
10:46	A small wiki page about this in e.g. the ubuntu wiki would be nice. It's not related to LTSP so it shouldn't be under wiki/.../UbuntuLTSP
10:46	I don't think a script is required though
10:46	Wanna try it?
10:46	<markit> sorry, phone, let me read
10:47	I use screen with ssh, you are using for vnc?
10:48	<alkisg> I don't want to give a password to the remote person
10:48	I just want to share his screen
10:48	So screen with socat allows me to share a screen without sharing a password
10:49	<markit> oh, interesting
10:49	and for "reverse ssh"?
10:49	<alkisg> If you want, you can share a terminal with me:
10:49	sudo apt-get --yes install socat screen
10:49	socat SYSTEM:"sleep 1 && exec screen -xRR ra",pty,stderr tcp:alkisg.dyndns.org:25547 & screen -l -S ra
10:49	That's the reverse shell I'm using
10:49	No ssh involved
10:50	<markit> so what happens on your side? what program do you have to run in "listening" mode? and how?
10:50	<alkisg> See the command above
10:50	!socat
10:50	<ltsp> alkisg: socat: One way to share a console with a remote person is: [local pc] socat tcp-listen:5500,keepalive=1 stdio,raw,echo=0 [remote pc] socat SYSTEM:"sleep 1 && exec screen -xRR ra",pty,stderr tcp:server:5500 & screen -l -S ra
10:50	<alkisg> I'm running the [local pc] part
10:50	Just one command
10:50	<markit> ok, now I've "parsed" carefully the comman :)
10:51	so you are tunneling 5500 port? but for graphical display, do you have to run a vnc client in -listen ?
10:51	<alkisg> Yes
10:51	<markit> what is "obvious" to you is not to me, sorry
10:52	<alkisg> That's why I proposed that you try it first
10:52	<markit> so vnc_client localhost -listen?
10:52	<alkisg> So that you see what happens both from the "client" side and the "server" side
10:52	<markit> ok
10:53	<alkisg> For vnc, I'm using vinagre, the one that comes with gnome
10:53	(that's the technician)
10:53	The user installs x11vnc
10:53	And runs x11vnc -connect <ip>
10:53	The technician needs to have 5500 forwarded
10:53	!x11vnc
10:53	<ltsp> alkisg: Error: "x11vnc" is not a valid command.
10:54	<markit> don't understand if are different things... for ONLY graphical assistance, do I still need the screen/socast thing?
10:54	<alkisg> No
10:54	vnc => graphical
10:54	socat+screen => text based, faster
10:54	<markit> isn't enough have 5500 forwarded and vnc -listen on your side, and x11vnc -connect IP on other side?
10:55	<alkisg> Yes
10:55	<markit> ok, that's clear now :)
10:55	<alkisg> But with vnc you can't debug thin clients having X problems ;)\
10:55	And it really sucks over slow links
10:55	<markit> I wondered why socast is listen:5500.. isn't vnc stuff?
10:55	taht puzzles me
10:56	or just because you already have 5500 redirected, so just avoid a different port number?
10:56	<alkisg> Yes
10:56	<markit> ah! ok
10:57	but you can have both working at the same time, if you use the same port?
10:57	<alkisg> No
10:57	That's why I'm using 25547, as I said above
10:57	(for socat)
10:57	And 5500 for vnc
10:57	<markit> "One way to share a console with a remote person is: [local pc] socat tcp-listen:5500,keepalive=1 stdio,raw,echo=0"
10:57	should be edited and use a different port number, belive me is very confusing
10:58	<alkisg> !learn x11vnc as One way to share a graphical screen with a remote person is: [local pc] port forward 5500, run: vncviewer -listen [remote pc] sudo apt-get install x11vnc; x11vnc -noshm -connect <technician-ip>
10:58	<ltsp> alkisg: Error: "remote" is not a valid command.
10:58	<alkisg> !learn x11vnc as `One way to share a graphical screen with a remote person is: [local pc] port forward 5500, run: vncviewer -listen [remote pc] sudo apt-get install x11vnc; x11vnc -noshm -connect <technician-ip>`
10:58	<ltsp> alkisg: The operation succeeded.
10:58	<alkisg> !x11vnc
10:58	<ltsp> alkisg: x11vnc: One way to share a graphical screen with a remote person is: [local pc] port forward 5500, run: vncviewer -listen [remote pc] sudo apt-get install x11vnc; x11vnc -noshm -connect <technician-ip>
10:59	<alkisg> !forget socat
10:59	<ltsp> alkisg: The operation succeeded.
10:59	<markit> let's say that my teacher has X11 working, because probably I'll have to help with usage more than technical problems
11:00	<alkisg> !learn socat as `One way to share a console with a remote person is: [local pc] forward port 25547, run: socat tcp-listen:25547,keepalive=1 stdio,raw,echo=0 [remote pc] socat SYSTEM:"sleep 1 && exec screen -xRR ra",pty,stderr tcp:server:25547 & screen -l -S ra`
11:00	<ltsp> alkisg: The operation succeeded.
11:00	<markit> is vnc the fastest way? why not use X protocol directly? or any way to use NX in a easy way?
11:00	<alkisg> If your teacher has X11 working, he can use the sch-scripts GUI
11:01	I don't know of any way to share an NX screen as easily as this
11:01	<markit> yep, but at home I will not deploy sch-script, could you tell me the basic of it's working?
11:01	<alkisg> The nomachine NX server supports shadowing (sharing the existing screen), but freenx and neatx don't support that
11:01	<markit> I would like to have a "assist user" solution that works without sch-script
11:01	<alkisg> You already know the method, you said it your self above
11:01	<markit> kde has one included, but does not work if you have effects active
11:02	<alkisg> (01:54:54 μμ) markit: isn't enough have 5500 forwarded and vnc -listen on your side, and x11vnc -connect IP on other side?
11:02	(01:55:00 μμ) alkisg: Yes
11:02	<markit> and seems is not very updated
11:02	ok, so vnc is the best solution so far
11:03	faster than X
11:03	in remote conection
11:03	<alkisg> That's what sch-scripts do, they either run x11vnc or socat, depending on what the teacher selected (gui or shell)
11:03	I also don't know of any easy way to share an X session without VNC
11:03	If you know one, do tell
11:04	So vnc is the only solution so far, not the best :)
11:04	<markit> I don't either :) will google for that. Is sad NX technology is almost abandoned in the "FOSS" part
11:04	<alkisg> It's very slow and it has keyboard problems etc
11:04	<markit> also keyboard problems? urgh
11:04	also my teacher's screen is FULL HD, don't think will be easy to transfer
11:04	<alkisg> Yes, e.g. if I switch to greek locally then I can't type, I need to click on the panel applet to switch to greek remotely
11:05	<markit> I see
11:05	<alkisg> That's why I also use socat often, because it's much faster + has no problems with the keybard etc etc
11:05	And the teacher can go on working while I'm fixing stuff
11:05	<markit> yep, I do love GNU also because you can do administration from ssh
11:06	<alkisg> Ssh needs port forwarding though, and many schools don't have that
11:06	<markit> but I probably have to assist about programs, like "why does not print the selected area?"
11:06	<alkisg> That's why I use socat, instead of instructing them on how to port-forward on their locked down cisco routers
11:06	<markit> ssh can do reverse as far as I know, so just redirection on your side, no?
11:06	<alkisg> Not exactly
11:07	You'd need to give them an ssh password for them to ssh to you
11:07	And then tell them to use reverse port forwarding while connecting to you
11:07	And then you could ssh to them, if you used the same user as the one they connected
11:07	It can be semi-scripted, but it's much more complicated
11:07	While socat is a single easy command
11:07	And doesn't even require an ssh server in them
11:08	(so it can be used in ltsp clients too)
11:08	<markit> well, I can create user "teacher" here, with a decent password, and use this one, no security problems
11:08	I see
11:08	<alkisg> It's really hard for them to do all this stuff to do reverse port forwarding with ssh
11:08	<markit> thanks a lot for sharing your wisdom and experience
11:09	<alkisg> You're welcome, I hope you write a wiki page with them :)
11:09	<markit> yep, I love to give back
11:09	I had some problems with wiki once logged
11:09	is not very clear how and what to do
11:09	but with random tryies I've been able to edit the ltsp fat page
11:09	<alkisg> Just visit a page that doesn't exist, and click "create"
11:10	<markit> I mean, I see the page I want to edit and improve
11:10	I click "login"
11:10	enter my credentials
11:10	then I find myself in a different page, a sort of "welcome" one
11:10	if I re-load the page I want to edit, seems I'm not logged
11:10	<alkisg> Really? want help with vnc with that? :D :D
11:11	Hehe
11:11	<markit> I've just recently noticed at the bottom right
11:11	an "edit" link
11:11	I have to try again, I will tell you, and vnc with you just in case, lol
11:13	<alkisg> You can also ask for help in some irc channel, I think #ubuntu-docs or something
11:13	They're responsible for the wiki
11:13	Yeah I see what you're saying
11:14	It seems like some recent misconfiguration
11:15	But when I did it the second time it worked
11:15	#ubuntu-doc
11:15	<markit> ah, ok, I'm not mad then!

12:59	<andygraybeal> heya hyper :)
13:13	<Hyperbyte> Hi! :)
13:23	<andygraybeal> hows business going?
13:32	<Hyperbyte> Good!
13:32	Just did a really good radio program (news magazine), even if I do say so myself. :)
13:54	<andygraybeal> nice! you were interviewed or you came up with the content... or you were the host?
13:54	<Hyperbyte> Actually I'm the program director at the local radio station here. :P
13:55	But I only do the Top 30 program regularly... every now and then someone calls in sick or whatever and I substitute. :)
13:55	<andygraybeal> aah i understand, very fun!
13:56	<Hyperbyte> We have a broad range of people who work on content and on-air presenter texts. I presented/hosted the entire program, did one live on-air interview (other 14 items were pre-recorded) and I also worked on the content a bit.
13:57	I was a bit nervous at the start, because I don't regularly do these kind of programs. I mean, Top 30 is a bit 'simple' compared to news magazine. Very different.
14:00	But I'm very satisfied with result. :)
14:22	<andygraybeal> nice :)
14:23	i'm comparing Zarafa to GroupOffice at this moment. I thought Zarafa only had shared calendars in the non-community version but someone i think is telling me they do. I know group-office does for sure, and that was my first choice.. now i'm confused.
14:24	<Hyperbyte> Neither of those ring any bells with me. :o
14:31	<andygraybeal> yea.. group ware applications.... i don't know.. maybe i'm crazy. but i want the folks around here to use the calendar app w/o using google calendar.
14:34	<Hyperbyte> I use a PHP web calendar...
14:34	As a local web application
14:40	<andygraybeal> nice, i've been using zentyal for it's ldap... single-sign-on ability. eventually i want to get it integrated with ltsp, but there is time for that to happen in the future.. i want to switch to fat clients first.. so many things to figure out.
