Streaming Problems with Realmedia via RTSP from ereserves with VLC Player (and Internet Explorer. And NetOp School)
- VLC-player
- version 1.1.9, but also currently newest 1.1.11 as well on Windows CXP SP 3
- opens from IE8 and Firefox 3.6
- but is not able to play files (tested even multi) through. Rather, it nicely falls on its face, with the audio stream simply appearing to stop, mid-sentence, after 2:38 (pretty consistently – a buffering bug? A great way to slip through pre-testing).
- In the LRC, I could hardly bring the taskswitcher up, let alone (15 minutes of waiting) the task manager, to even find that vlc.exe is the culprit, with a CPU utilization of 99% solid (Ouch!).
- Not quite so bad in the office computer where it hovered slightly above 25%, maybe busying only one CPU core.
- My Google searches do not find anything quite similar.
- RealPlayer 14 to the rescue?
- In IE8, RealPlayer does not open when clicking on the web page link with the RM file which causes a dialogue to open if VLC-player is the default player, rather a strange unplayable content error..
- In Firefox, RealPlayer open and plays (and pre-buffers) the stream completely.
- Note that ereserves “download as zip” cannot serve as a workaround: gives you only the links like http://dlib4.uncc.edu/streaming/media_play.php?file=9364cb66b9e1cae26aed0f471e9eab5b, which require you to re-authenticate, even if in the same browser session, and do not redirect to the resource, neither audio nor web page form which you could launch the audio (in short, I do not get what this download as zip is good for)
- Next Problem: This may work on my office computer. In the lab we have NetOp School installed. That adds another layer of NetOp School problems which look like they can be resolved
next time the lab is reimaged. For now, use instead audio from Moodle metacourses where possible.next time I get around to design and run a Symantec-Ghost Software and File Action on the computers (all LRC lab PCs) and test the result (on PC10) which was now.
Netop: Nhstconf.ndb update/locking error
Implementing a Deepfreeze upgrade via Symantec-Ghost file operations instead of
• To upgrade from novell to AD I need to implement a deepfreeze maintenance thaw window, to allow updating of the domain machine password on the normally frozen client.
• If you have no other than built-in/FOSS means, you can probably achieve this with RunOnce, AutoAdminLogon, AutoAdminLogonCount, and reading out the client @computername DefaultDomainName with AutoIt. I rather try using Ghost:
• Put files on headless to be able to ghostcast them without access to fileshares
• ghosttask: df6 boot thawed (I need to unfreeze, w/o deepfreeze clients connected to deepfreeze server)
• ghosttask: df6 uninstall:
o ghostcast transfer deepfreeze 7 and 6 installer to c:\
o C:\df6wks.exe /uninstall
o Reboot
• Ghosttask: df7 install
o ghostcast transfer deepfreeze installer to c:\
o C:\dfwks7726.exe /install\
o reboot
o Should be safe to have the installer lie around: While Deepfreeze 6 uninstall does not require a password, it will be history; also, to permanently uninstall, you first need to unfreeze, which requires a password
• ghosttask: df7: boot thawed : Dfc.exe [installs into path] pwd /bootthawed
• ghosttask: winsockreset
o netsh winsock reset or cmd /c netsh winsock reset
• ghosttask:
o ghostcast transfer schliessnicht.exe into C:\Documents and Settings\All Users\Start Menu\Programs\Startup to keep Sanako alive for oral exams (permanently, this should be enabled using this TBA:extension method to do advanced remote control of Sanako study1200 student clients; where is the delete option? can only think of overwriting with an empty file of the same file name)
• ghosttask: df7: boot frozen: Dfc.exe [installs into path] pwd /bootfrozen
• as long as I do not make changes to the default user and to user settings (like what app rm is associated with), I do not need to reimage – BUT: to run acrobat, flash, windows updates, without reimaging, instead of task, I would need to automate gui interaction after autoadminlogon as labadmn, which means
o ghosttask: ghostcast transfer 1 autoit that rewrites registry and reboots to autoadminlogon
o then startup autoit to automate gui interaction with nal?
CAOS ereserves not compatible with Sanako Study1200 Webbrowser
- Last week I noticed in the LRC that I cannot open the ereserves with language learning audio files to my students by using the Study1200 Webbrowser’s “follow” feature .
- While sending the audio listing page still works, including the login page which the students get redirected to, and which, upon successful login, redirects them to the listing;
- Getting to the actual audio file launcher page fails, since this is a popup window which the Sanako Webbrowser first blocks, while redirecting the launcher of the popup to the home page
- No pressing of modifier keys seems to be able to bypass the popup blocker. Is there a setting in the Study1200 Webbrowser to modify this behavior.
Solved: NetOp School NLSP.dll prevents streaming of Real Media via RTSP on student computers
- On a NetOp School system, Realplayer 14, when trying to load e.g. rtsp://dlib4.uncc.edu:554/e_reserves/CD4French1-7.rm (from Firefox, or disk, authenticated), crashes nlsp.dll (version 6, part of of NetOp School from Danware). This is the NetOp Browser Policy IP Filter.
- The MS-windows appcompat contains this:

- NetOp support advises to try, among other things, resetting the Winsock catalog via "netsh winsock reset", which seems to work on a testmachine.

Student peer assessment options for a more “social learning” experience in Moodle 1.9.
- The most simple solution, briefly explained:
- Add a forum: button: “Turn editing on”, dropdown: “Add activity: “discussion”, Set dropdown “Forum type”: “a single simple discussion”/ section: grade, dropdown: “aggregate type”: “average rating” (also set your max attachment size if you want uploads of multimedia recordings).
- Set Permissions: course administration block / item:assign roles / tab: override permissions (we do not have this!) / section:forum, enable checkbox:”rate posts”, disable checkbox: “view any ratings”, “view ratings” .
- Visually explained (notes deviously: “if you do not have tab: override permissions, ask your admin”. If she says “no”, ask to enable the workshop module in Moodle 1.9. If she says “no”, ask to upgrade to the workshop module in Moodle 2.0. If she says “no”, ask her for other ideas how to do “social learning” in Moodle…
