latest TELA yosemite laptops getting errors that require re-installation of OS

Ict Manager <i...@westlandhigh.school.nz>: Mar 05 04:19PM -0800 Anyone else having this problem?   users are getting "you do not have permission to" errors. permissions fix, recovery-resetpassword fix both fail, only answer is to do those then a complete re-install of the OS. It appears to happen after an OS update. And its getting quite annoying. its a two hour repair and i've 25 laptops just in.

Stephen Moran <ti....@ihug.co.nz>: Mar 06 01:27PM +1300 Does the standard Admin login work OK? Do a ls -le /Users/ in terminal and check what the permissions are on the home folders, maybe the latest TELA login hook has broken. A simple chmod -RN /Users/ might fix it.   Stephen

Short term remote access

Craig Knights <craig....@gmail.com>: Mar 06 11:56AM +1300 One of our staff is going on short term parental leave. He has an accounts program on his windows desktop machine he'd like to use from home..   So... options.. he could RDP in to our existing RDP server and then RDP to his desktop and run his program, but double RDP'ing is confusing and sometimes slow...   Could install the program on the remote server.. license cost? would having that program on there for all to see be a good idea?   Could enable RDP on his computer, set a static IP address, get the computer an external address, say name.mcglashan.school.nz <http://callum.mcglashan.school.nz/>, just like our RDP server, but overkill for short term access??   Or I find something like TeamViewer but not $870 for a license!!...   any good ideas?   thanks, Craig

Cable testing of equipment in schools

Bevan McNaughton <bevan.mc...@southlandgirls.school.nz>: Mar 06 09:33AM +1300 You are completely fine opening a desktop computer to fix it as the PSU from 230VAC is completely self-contained and it's output is no more that 12V DC. In cases where it's an external Class 2 PSU (like a laptop power supply) it's isolated from mains anyway.   IF you open up the power supply on a desktop PC (internal model) itself then it will require electrical re-certification. IF you open up a Nework Switch which has an exposed PSU on the same casing as the main PCB then it will require electrical re-certification.   The main issue is that the PSU (for a desktop PC since it's 99% of the time a Class 1 appliance) should have full grounding from the PSU to the chassis - obviously this is always the case since the PSU bolts/screws onto the chassis. If you have any type of dubiousness about it then get it appliance tested, or measure the difference from earth to the chassis at no more than 1 Ohms.   Tell the sparky to do his own homework.   Regards, Bevan McNaughton.     -- Bevan McNaughton Intranet Manager   Southland Girls' High School 328 Tweed Street Invercargill 9812   Phone: +64 3 211 6030 Fax: +64 3 216 9010

"Patrick Dunford" <kahuk...@gmail.com>: Mar 06 01:33PM +1300 The electrical code is to do with opening a case that contains live mains components. In the era of AT-type computers these had a mains switch in the chassis which had live wires going to it. These cases could not legally be opened, although this was widely flouted.   Since the evolution to ATX and other similar designs of PC, the mains components are all fully contained within the power supply and there is no such issue unless you open the power supply case.   However if you service Mac or other types of computers these often contain live power supply components without a separate enclosure and if you open such a device the regulations do apply.   From: Patsy France Sent: Friday, March 6, 2015 8:45 AM To: techies-f...@googlegroups.com Subject: [techies-for-schools] Cable testing of equipment in schools   Hi all,   I am a technician working in a primary school and my role is technical support for all the equipment etc, repairing computers, swapping out faulty power supplies, and similar tasks.

"Patrick Dunford" <kahuk...@gmail.com>: Mar 06 02:06PM +1300 Electricity Act 1992 and Electrical Regulations 1997 are the relevant legislative provisions.   Electricity Regulations 1997   http://www.legislation.govt.nz/regulation/public/1997/0060/latest/DLM229267.html   Part 3 Prescribed electrical work and worker safety   (2)17Prescribed electrical work (2) The following work is deemed not to be prescribed electrical work: (b)repairs or adjustments to works, electrical installations, fittings, or electrical appliances or the replacement of extra-low voltage or mechanical fittings in electrical installations or electrical appliances, provided (in each case) that the work can be undertaken without removing any screens, covers, or the like designed to prevent inadvertent contact with fittings intended to be supplied at voltages above extra-low voltage:   Extra low voltage from memory is 50 volts. This allows you to work on telephone, network cabling and audio cabling (which generally can carry voltages up to 50 volts DC) without requiring electrical certification; above this voltage the clause above applies i.e. without removing any screen or cover that protects against contact with higher voltages than “Extra low voltage”. Depending on the device this screen could be the outer case of the device. Audio wiring: Microphone cables can carry “phantom power” at DC 48 volts. Speaker wires are where the highest voltages are found which can be more than 50 volts in a lot of cases. Telephone wiring: Generally phantom power of about 48 volts DC is found on POTS wiring to supply connected analogue phones. However ring voltages are usually of the order of 70 volts AC which makes the application of the above clause rather hazy. Network wiring: It can carry POE power which is typically at 48 volts DC, for supplying network equipment.   From: Patsy France Sent: Friday, March 6, 2015 8:45 AM To: techies-f...@googlegroups.com Subject: [techies-for-schools] Cable testing of equipment in schools   Hi all,   I am a technician working in a primary school and my role is technical support for all the equipment etc, repairing computers, swapping out faulty power supplies, and similar tasks.

However ring voltages are usually of the order of 70 volts AC which makes the application of the above clause rather hazy. Network wiring: It can carry POE power which is typically at 48 volts DC, for supplying network equipment.   From: Patsy France Sent: Friday, March 6, 2015 8:45 AM To: techies-f...@googlegroups.com Subject: [techies-for-schools] Cable testing of equipment in schools   Hi all,   I am a technician working in a primary school and my role is technical support for all the equipment etc, repairing computers, swapping out faulty power supplies, and similar tasks. I have been in this role for almost 19 years.     Today the person who is in our school doing cable testing told me that I am not supposed to be opening up computers to fix them as it is against the Electrical Safety Act 2010.     I tried researching it but couldn’t find out what he is talking about.     Although I am a qualified technician and can build computers, I don’t take power supplies apart, I just swap them out with new ones if they fail, swap out ram, upgrade motherboards, graphics cards etc.     I have looked at the documentation he mentions but can’t really see any reference to this, has anyone else had experience with this?     Thanks for any ideas on the subject.     Patsy       ----------------------------------------------------------------------------   Patsy France IT Technician/Network Admin - CompTIA A+ Manurewa Central School Hill Road, Manurewa.

Musac.

Chris O'Donoghue <codon...@gmail.com>: Mar 05 12:54PM -0800 Hi Raewyn,   Musac has made no decision to cease support and development for Musac Classic. Rest assured, that if you think that Musac Classic is best for your school we'll be there to support you.   Kind Regards   Chris   On Thursday, 5 March 2015 17:31:32 UTC+13, Raewyn Nicholson wrote:

TTS have it running perfectly at our school, yes there are some issues when people don't log out of the sidebar and you need to update the system - easy fix around though. Absences crashes now and then (wireless) but not that often. Have always found MUSAC support fantastic - yes they do need to comply with MOE policy as do all vendors. Love the fact though I can create and play and customise without having to bring another party in to pay for the privilege. We have been told that Classic will no longer be supported from 2017 - we will be looking at all vendors out there including MUSAC Edge.   Raewyn Nicholson   Administrator 09 627 9940             On 5 March 2015 at 16:01, Chris O'Donoghue <codon...@gmail.com> wrote:   :) Indeed,   As I'm sure you are joking here, I'll just react to the extent that: modern cloud based development is based on a continuous deployment model, while we are not at that stage yet (or in the near future) we are constantly working to release code when it is ready, to our cloud service, edge.   I've never met Rory, so I couldn't comment.   Kind regards   Chris   On Thursday, 5 March 2015 11:33:17 UTC+13, Rob Wood wrote: Twice weekly version changes - hmm.

We're finally going to change to Kamar later this year, it's been understandably difficult for our MUSAC guy to give it up.   But until that happens, this is the problem we have.   Last year in June our long suffering main Windows file server gave up. Now we had been expecting this and had migrated our domain controllers to much more modern hardware. We also got a nice Netgear ReadyNAS 512 to serve up files. Great, goes much faster, RAID 6, 8TB. Nice backups etc.. Runs Linux.   I put the MUSAC share, the M: drive on there, great, fast, nice. OK. Worked just fine from June until this year, a real performance boost. So for the last month, all Windows machines on gigabit wired LAN connections and our terminal server (most staff run MacBooks so they use this heavily) get Musac data access errors. The terminal server usually needs a reboot each morning to get Musac to run properly again.. The databases themselves are not corrupting. iPerf shows that I can happily pull 930Mb/s all day from the NAS. Something seems to have changed.   So was putting Musac on the NAS a big mistake? Reading Musac's website suggest it is. They say Windows all the way and no SMB3.   My current plan is to move the Musac share off the NAS onto the terminal server's disk, so it can run locally for those users. The users that run it on their machines, (maybe 5 of us) will have to have to run it from a share on the terminal server.   Anybody like to weigh in with opinions?

Chris O'Donoghue <codon...@gmail.com>: Mar 05 05:11PM -0800 Hi Patrick,   Yes a blog post about this time last year, which said we will support Musac Classic until "at least" 31/1/2017   In the same post it said "We will not force our loyal customers to make decisions until they are ready."   No decision has been made to end date Musac Classic.   The 2017 date is not seen by anyone here as an end date, more of a commitment that we will not be dropping our classic product.   Kind regards   Chris   On Friday, 6 March 2015 13:36:45 UTC+13, Patrick Dunford wrote:
