Sadly those machine will simply not be powerful enough to manage labs of over 15 machines. Applying the patch only fixes connection lag.

Sadly the sorting function of iTalc is kind of wonky but there are work arounds. Your best bet is to take one master and sort it the way you want it and align them. After you are done sorting and setting the configurations you want for a base template exit the program and copy the file C:\Documents and Settings\%USERNAME%\Application Data\iTALC\personalconfig.xml on a share or something. Now everytime you install a master you will want to copy that file into the machine. You can also copy it into defaultuser incase you have multiple teachers logging into the same machine. Also for the slowness have you tried patching the teacher stations with the TCP fix from http://www.lvllord.de/? The only other thing I can think of that would cause slowness is the specs of the teacher machine, you have to have a pretty decent machine with atleast 512mb of ram and pentium 2.8GHz or more depending on the number of workstations in a lab, the bigger the better pretty much.

I'm not sure if you have noticed already but when you are connected to a computer in full screen there is a toolbar with options that drops down when you navigate your mouse on the top most part of your screen. In later versions of iTalc you can also change the remote connection to windowed mode from that drop down toolbar so it isn't locked in full screen.

Alrighty, if you do that I'll fix it up and hopefully it'll help some people out. I also don't have a guide for installing it on linux clients so maybe someone will provide that eventually.

I can post the step by step guide that I hand out to fellow coworkers in the ITalc thread. It's a bit long. Edit: actually I just noticed I had already posted a basic guide on the first page of that thread. I could simply update that instead since alot of it still applies.

ITalc can do this task pretty easily, I let my teachers take care of it since it's as simple as opening the program, clicking connect and typing in the login details. Plus if your labs support wake on lan you can turn everything on with iTalc aswell. http://italc.sourceforge.net/ Be advised though that deploying it is not straight forward and if you want to figure it out yourself be prepared for alot of time investment. Here's the thread you could also check out. http://www.edugeek.net/index.php?name=Forums&file=viewtopic&t=7400

I would strongly suggest not using windows shares for the keys. I only got that method to work correctly with samba shares so if you have a linux box available use that instead. ITalc itself as a service cannot establish a connection to a secure share on a Windows server and if it actually is possible I have never found the solution and moved on. The only time I use a window share for iTalc is for the globalconfig.xml file. If you want it to work correctly copy the public admin key locally instead of on the share and change the registry key accordingly or if you absolutely must use a share put it on a samba on a linux box. Test it with one machine first with the admin keys locally on it and it will work.

Ok in that case if ever you want to try it pm me and I'll give you a hand, I'm even willing to go as far as call you on a landline if it's necessary. I have a step by step method that makes installation of entire labs quite easy and functionnal.

That error is caused by the master not having the correct public and private key to be able to authenticate the connection. I am figuring that since you only metionned the demo mode iTalc itself is working correctly. You might need to provide more details of what kind of setup you are using. Example, are you using identical teacher public and private keys everywhere? Did you add an admin key or other additional keys to the setup? Here's a random tip for demo mode aswell, if the master is on a wireless connection it would be aviseable to use ethernet instead and make sure to configure it properly in the iTalc settings. Wireless with demo mode is simply not a good idea.

That's too bad. If you're ever interested in giving it another go let me know and I'm sure we could get it running correctly. ITalc runs great but there are definitely alot of obstacles to overcome before that can happen.

What version of iTalc are you running on the computers? If you're running 1.0.3 or 1.0.4 I would suggest downgrading to 1.0.2 for the time being. The masters can stay at 1.0.4 without any problems.

The master needs alot of CPU power to handle a classroom. I'm using a T2500 2.00 GHZ laptop and 32 computers uses about 35% CPU. Nothing much can be done about it.

In our schools we use Chancery Winschool and we also can only export limited information into a csv file similar to you. What I do to prepare the xls for AD import is to make a new excell sheet, import the csv into the second page of this xls. On the first page where you will store your AD formatted sheet I make functions so that I can retrieve information off the second page. This example is in french but it might help you anyways, you'd have to find the english version of concatener. Say if you have your first and last name in collumn A and B in page 2 this would do what you're aiming for. =CONCATENER(Feuil2!B1;" CN = ";Feuil2!A1;" ";Feuil2!B1) (edited since I forgot you were doing multiple columns. This would cover sAMAccountName) The end result would be exactly what you typed. This function would complete the format you're looking for and you can simply drag it down for the rest of your lines. This is the method I use and it doesn't take all that long once you have a sheet ready.

Something you could try is to copy the admin key to the teachers. I haven't tried it myself but I'm pretty sure that would work. You could always simply create a seperate globalconfig for admins only which I'm sure would work.

The page is most likely still cached on your computer. You'd have to delete your temporary internet files for it to not be visible anymore I would think. I also tried deleting a html and I come to the same result.

First thing you should do is check the error logs in the windows directory. There isn't much advice I can give based on the information of the error you provided. Check the italc_client.log file within the clients that aren't working.

What you will want to do is create a read only share for those teachers and place the globalconfig.xml file that contains your computers and classes into this share. Next, you're going to need to set the registry on every Master so that iTalc goes to that location instead of localy. The registry location is here: HKEY_LOCAL_MACHINE\SOFTWARE\iTALC Solutions\iTALC\paths Create a chaine value named "globalconfig" and put in the location of the file "\\SERVERNAME\SHARE\globalconfig.xml" The same can be done for personalconfig.xml also but I have yet to successfuly make it work because it gives an error. It's too bad since the alternative is copying the files manually. Personalconfig is useful since it keeps the computer sorting information, instead of having the displayed computers all over the place, so it saves alot of manual sorting, resizing, and headaches.

Here's a nice article on your problem that the creator has written up on the Wiki. The admin keys are not able to be used to access the client. My set up only uses teacher so I have no experience with setting up multiple group levels. http://italc.sourceforge.net/wiki/index.php?title=User_FAQ

You'll have to check your server logs to see what the error is. Especially /var/log/apache2/error.log

Other options that don't breach the EULA would be to downgrade the TCP.sys file to SP1 (not tested but I don't see why it wouldn't work) or bring the entire OS to SP1. My personnal opinion on the matter is that Microsoft put such a limitation in one of their servicepacks to slow down virus outbreaks for home users and they should have made an option to modify it. It's true that not all machines ever require more than 10 TCP connections but sometimes, like with iTALC in this case, having more than 10 connections is a must.

I have found a new trick to get this working very efficiently and resolved one of my problems I encountered when testing out 1.0.3. If you are using the Master on a Windows XP SP 2 machine you need to modify your TCP connectivity limit. SP2 has introduced a feature that limit concurrent TCP connection attempts that are possible to 10 per seconds which doesn't work very well with iTalc. After changing the limit, the Master clients becomes way more responsive and my teachers have confirmed a huge improvement in performance. I used this tool and updated my tcp connection limit to 100. It reports as a Virus with McAffee since it modifies windows TCP.sys file but I can assure you it isn't. Use at your own risk in any case. http://www.lvllord.de/?lang=en&url=downloads

HP is very subpar and I can easily say I hate them. Their products are crap and they seem to be breaking within a year. We are issued HP nc8430 laptops and one of our guys laptop motherboard blew after 3 months of regular use. Our HP Proliant server had a hard drive failure within a few weeks of uptime. Desktops and monitors are breaking often. I definitely prefer Dell over HP we have machines over 3 years old that are still going strong. Every time we call them for piece replacements it's a gigantic hassle. They transfer us all over the place then we end up getting hung up on after about 30 minutes. If it was my call to avoid switching to HP I would of done it. Now we're stuck with them and it's really dissapointing and frustrating.

Hi everyone. Found this site by accident and added it to my favorites. I manage 4 schools and help out the other techs sometimes. Pretty slow this time of year so I'm starting alot of pilot projects.

I'm currently in the process of installing ITalc in all my labs that have windows XP clients, a 2003 server and also a samba share which I'll explain later. I'm pretty satisfied with it with the exception that any Classroom with over 20 machines becomes unuseable (all machines become unreachable even though you can remote with them). My only solution so far is dividing the labs into two groups. Here are the things that I needed to setup for the clients and masters so I could easily deploy it. 1. Install a master so I can get the three keys I need. A share on the 2003 server for the Public key which I create on a master. During the future installs I point towards this share by copy and pasting the link. On some machines, typing out the address manually causes freezing so copy and pasting it is a sure thing to avoid this problem. 2. Create an invisible share on my samba for the public and private teacher keys which are created by that first master install. Why a samba share instead of Windows? The service itself seeks for this file and I haven't figured out a way to assign a local computer service read permissions on a windows server. Samba is helping me at the moment with this issue and the clients can find the keys no problem. It's easier to make these 3 keys available on network shares unless you don't have a box with samba. The other option is you'd have to copy it on every client and master so they can communicate with each other. 3. Create registry file with proper configurations. I have one for the master and one for the clients. The first registry setting is the path to my samba share with the teacher keys which clients and masters use. The other setting is for the windows firewall. Did you forget about the windows firewall? I certainly did when I first tried testing it! I simply add both ica.exe and userinfo.exe to authorizedapplications and luckily registry importing makes this an easy task. I don't know if userinfo.exe needed to be added but I didn't take any chances. Here's how my italc.reg file looks like. 4. Fourth and final setting is to put globalsettings on a server share and making sure the masters are pointing towards it. The reasoning behind this is to add computers and classrooms only once since I have multiple teachers who are using this. Make sure they only have read permissions so they don't mess it up and delete classes and computers. I have full rights to the file so I simply add the computers and classes myself. Here's my IMA.reg file that I apply to masters only. I hope this helps some for anyone who plans to install this in the future. Once you get these things setup everything will work great. My only issue with the program so far is as I said before, if you plan on having groups of over 20 computers the screens will become unreachable, even if you can still remote with them. I'd like to figure out how to fix this but I haven't had time yet. I have theories and I'll try to figure out a solution this week. Also, this is the command to unregister the service if you need to uninstall or install it to another directory like I had to do.
