How students access language learning materials on the Library ereserves system
- Note the important update in red below.
- This has been tested at post date with Firefox. ereserves seems to be not compatible with Internet Explorer 8: i
- On the Library home page, from the top menu: “Research & Course Help”, choose menu item: “Course Reserves” (or, if this menu changes again, I have a hunch that deeplinking may be more stable: http://library.uncc.edu/caos/coursereserve, what’s in a URL…),
- sign in with your Ninernet ID,
- enter search term
- select from the dropdown “search by name”, an enter part of your course name in the textbox,
- or click on tab:”Course Reserves Pages by Instructor”, and from the dropdown, select your instructor,
- click search,
- then select your course from the results grid.
- Enter the password, which has been given to your by your instructor.
- In the results grid, click on the desired chapter and tracks. Note: You need to disable your web browser”s “popup blocker”.
- In the popup window, click on link: “More information”,
- when offered, , like in this screenshot:
- you cannot save the file, or rather: only a text file with links to the audio which you cannot play, like rtsp://dlib4.uncc.edu:554/e_reserves/CD1bonneforme12-16.rm). That is by design.
- Instead of trying to save, select to “open” the file. You need have a streaming audio playing software installed, like Real Player or the open source VLC-Player.
- instead of VLC, as offered by default, like so :
- choose “Open with”, “Other”, pick “RealPlayer” from the list, like so:
- Here is a more on what does not work with ereserves. The only combination I could get to work with eReserves streaming audio is – see resulting screencast (requires Windows Media Player) of streaming a long file successfully – is RealPlayer 14, Firefox 3.6 on Windows XP3, and that only after resetting the Winsock catalog which I can do for the entire LRC only nownext time the lab is reimaged. For now, use instead audio from Moodle metacourses where possible.
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.
How LRC assistants can print LRC jobs from the reception desk
- If you have (ONLY! printing is tracked) work-related jobs to print from the reception desk, please use this method:
- Choose “print” as normal and then this Toshiba printer driver ONCE I HAVE IT INSTALLED:
- the printer driver will ask you for a code; the code in the LRC Moodle announcement board sticky post, above the threads:
- You can pick up the print outs in the mailroom behind the LCS department’s main office.
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.

- NetOp support advises to try, among other things, resetting the Winsock catalog via "netsh winsock reset", which seems to work on a testmachine.
How a teacher creates and grades a Moodle streaming video assignment.
- Click button: “Turn editing on”, from the “add an activity dropdown, choose: “video”, like so:
- Edit your assignment, like so:
- using the following options (or else expect problems)
- Due date: not DISABLED (is the default)
- Prevent late submissions: YES (is not the default)
- Allow resubmitting: NO (is the default)
- using the following options (or else expect problems)
- after you post your assignment and your students took it, like so,
- and if you turned notifications (not recommended; rather grade the assignment well after the deadline, or else expect problems) on (if you get already enough email, remember you can turn notifications off, rather send a deadline to the assignments which the students can see in their calendar, and until they get used to it, tell them there will be more video assignments, best: make it a routine and leave 2 for extra credit could be enough to get everybody to catch), you will get an email like this:
- where you click either on the link (1) to go to the assignment, then click through to the submissions (3)
- or on (2) to go directly to the grade book:
- where you are best advised to click on the button: “grade” to view the video submission, , or else you might run into this bug.
- In the grading window,
play the video, add helpful comments, if any, add final Grade and click “save and next” (but click “next” if no video submitted yet and you grade before the submission deadline. Better: do not grade before the submission deadline). - If video seems unwilling to play (frozen frame), drag the play cursor forward on the timeline underneath the video.
If this does not unfreeze the video, let the timeline run to the end (both workarounds have helped with Kaltura issues we encountered here).
