  1. I stand corrected. It should be possible to still run python locally with the python folder set as read only. That should work round this particular issue. I will have to look into this. Just what I needed - another task to do... I'm still not sure that giving students full access to a system is necessary for what they need to learn. Admin access should only be given out when there is a specific documented need. How do you stop your users from reconnecting the virtual machine to the main school network?
  2. We found a couple of laptops last year. One hadn't been used since 1998, the other was an Acorn A4. Both were faster than the laptops we have now... And I nearly resorted to using a 3.5" floppy disk earlier when I couldn't find a memory stick. Today was a bad day.
  3. We install locally. Setting up virtual machines seems like a lot of work as well as more to go wrong, and I can't see the benefit, but I guess in a higher risk environment there might be some.
  4. I'm not an expert, but I think you need to add two more static routes - one route for each subnet, and keep the existing route for your gateway appliance. Then you will need to add a default gateway on your dhcp server (or on each client if you set them up locally). The default gateways for clients need to be either 192.168.1.250 (for any client starting 192.168.1.*) or 10.20.28.1 for any client on the other subnet. Something like: ip route 192.168.1.0/24 192.168.1.250 ip route 10.20.30.0/22 10.20.28.1 Also you will need some form of dhcp relay. I think these are the right commands for your switch: vlan1 ip helper-address exit vlan 2 ip helper-address exit You need to replace with the IP address of your dhcp server. Your dhcp server will then need a scope set up for each vlan. I might be completely wrong on all that though, so use with caution. I'm sure someone will be along soon with the right answer.
  5. Silly question, but have you restarted the iis server? Also, how have you got PHP setup? is it FastCGI or ISAPI? If fastCGI, then there is an option under CGI options called "impersonate user" that might help. I think this needs to be set to True.
  6. We developed a system in house for this. Its web based, and uses a barcode printed on the students id card. there are several scanners around the school running off of a dreamplug linux pc, a mini screen and a barcode reader. I would replace the dream plug with a raspberry pi if we did it again, but we made it before they came out. We also extended the system to print the id card as I got fed up of figuring out ID Pro every year. It doesn't write any data back to sims, but we do get students names, reg groups, year groups and photos out of sims. What are your requirements? Do you need any reporting, sims integration, or just a list of whos on site and off site? We use Vericool reception for the lower school, but found this didn't work fast enough to register the whole sixth form every morning.
  7. What everyone else has said. I've been riding a scooter for about 3 years and its great. I ride about 3 miles to work every day. It takes me about a 1/3rd of the time as on the bus, and costs about the same when spread out over 5 years. Be prepared to have an accident. It will probably happen at some point. There are so many selfish and rubbish drivers out there. I meet at least one every day. I'm pretty sure some of them are trying to kill me - there is no other explanation for some of the driving I see. Get some protective gear. It makes so much difference. It still hurts with it all on, but you don't get all the cuts and bruises when you go scraping along the road on your face/backside. I've come of about 3 times now, usually on the way to work in the morning when I'm thinking about something else and not focused on the road. I got a honda pcx 125 from the local dealership. They've looked after me well. They do finance offers so you can spread the cost over 3 years. I was also able to get the other gear included on the finance which was worth it. If you have the option to do the cbt and any other training then its worth it for the experience. You have to do the cbt anyway.
  8. If you need to do routing on it, you probably want something beefier. We have some in our server rack and they haven't missed a beat in three years. 1 for iscsi, one for vmotion and one for the main network with a lacp link to the core. I wouldn't use one for a core switch except in an emergency. Still miles better than anything I've tried from netgear though.
  9. 1910s have cable diagnostics. Its hidden under VCT (virtual cable test) under the device menu on the left hand side of the web interface. It should be noted that the port you are testing will go down for 5 seconds. There are also interface statistics under the device menu.
  10. I think you are right. You are storing a significant proportion of the schools data. Who is responsible for the backup? What happens when you need to migrate from one cloud provider to another? Who's going to move all the documents? We found this when we moved VLE and email providers. So much stuff couldn't be moved.
  11. The HP (ex 3com) v1910 switches are pretty good. They are cheap and really reliable. Never had a problem with them.
  12. Not sure if that was aimed at me or not, but we back up to a nas box at our partner school. We will hopefully have a similar arrangement for them soon.
  13. Veeam Backup and replication can do all of that I think. With v7 you can do either a file backup or a vm backup, and you can pick which drives you want backed up/excluded as well. Each vm can be backed up by multiple jobs if required. I would backup the whole vm, as you can restore individual files from a vm backup if needed, and then you have the whole vm backed up if you need to recover the whole thing. Its pretty easy once you know how. Much nicer than backup exec. Veeam 7 also includes backup copy jobs and tape loader support if thats any use. I've just changed our offsite backup to a backup copy job so it isn't snapshot-ing the VMs 3 times a night, only 2. Our backup is over our internet connection though. We don't use external harddrives. I believe file backup is a bit slow in v7. File backup to tape is. I've not tried to disk. Its supposed to be improved in the next version. This is because the system is designed to backup a relatively small number of large files. Backing up existing backup files to tape and to other storage is pretty fast. There is a free version, and I believe they support it through the trial period if you have any issues.
  14. Synology and Qnap are both good for this sort of thing. I slightly prefer the interface on Synology. I have a Qnap thats been in about a year, and a Synology for about 4 months. No problem with either of them.
  15. Found one broken fibre link when I got in. It took out about a quarter of the school. Managed to patch round it once I'd reconfigured a couple of switches. Then the cashless catering wasn't syncing with the online payments. Why is there always something on the first day back? Could have been worse I suppose.
  16. Its probably also because of the various business models of free software. There are some free antivirus products out there - clamav as already mentioned, and avg etc. Broadly speaking you have three types of free software: Open Source - developed when someone is interested in a project, or has a new way of doing something. This relies on someone skilled who thinks its worth giving their time for free. Ad supported - This probably isn't great for antivirus, and many people probably wouldn't trust it. Spiceworks seems to be doing well out of this model, so its not impossible. Limited feature set - Businesses can normally afford a small amount for more advanced features. Most of the enterprise features for AV are reporting etc for large networks. Home users don't need it, and even if you can get only 50p a device you can probably make money. So the enterprise features are an advanced option, so would be paid for in the last option. You probably don't want your antivirus popping up with adverts while you're working. That leaves open source, and most developers seem to prefer working on higher profile projects like kernels and web browsers and GUIs. Reporting engines probably arn't the most exciting projects to work on. Its not impossible that this will change, its just no one has done it yet. Wiping the device each boot is great except that: 1. It takes time, and 2. Now OSs are becoming more stable, reboots are less frequent. So you are pretty much unprotected until the next reboot.
  17. Had the same problem last year. Sky where quite helpful at getting it resolved. Only problem we had was the account was in the name of a previous tenant, and no one knew the password. But it was all fine once he called them up. We also had to have someone look at the phone line as well. When they saw how old the router was on their system, they said straight away it needed replacing. They were surprised it was still working at all. Now its all fine and much faster than before.
  18. I think it would be a bad idea to run without AV. I don't let anything connect to my school network unless it has some form of AV on it. Is your objection financial or technical? There must be loads of low cost AV solutions out there that would be better than nothing. We get sophos included with our LEA services, I think this is fairly common in across the UK. How would you know if malware was getting through your other lines of defense? Tools like the sophos enterprise console can give a really helpful overview of what's going on on your network. Looking at what goes on on mine, I would never remove the antivirus from any of our computers.
  19. Depends on whether its cisco or cisco linksys phones. Cisco phones need SIP firmware to be loaded on to them rather than the standard cisco firmware. You might need to pay for a support package to get access to this. linksys ones do sip out of the box (I think). Not all cisco phones have SIP firmware available. I think this is especially true of old phones that you find on ebay. Check carefully before you buy, and get one or two to test before buying lots of them. Most other SIP phones should work with 3cx. I use Grandstream phones with Asterisk, but they should work just as well with 3cx. I find the grandstream phones are better documented especially if you use them with asterisk. Cisco phones are really designed to be user with Cisco Call Center, and anything else can be a lot of work. A plain asterisk system may also be worth looking at. I find it more flexible if you want to do anything too complex. But it sounds like you want something a little less diy than that.
  20. We have some of the larger tower PCs. The internal components are Asus, so great quality. The cases of the model we have probably wouldn't be tough enough in a classroom environment, but are brilliant for home/office use. The slim line PCs look much tougher though (going by the pictures online). Haven't tried the after sales support, but then we haven't needed it. Some of ours we just used as a base, and added other components that we needed. We added a graphics card, blueray writer and ssd. The components are all standard, so it wouldn't be a problem supporting it yourself. In terms of performance, these are great value for money.
  21. We've been using these little wall mount ones: Vison Techconnect Stereo Amplifier V2 (TC2-AMP2) - www.misco.co.uk They take up much less room, and don't have as many complicated controls on. You can wire up two more inputs on the back to an av patch panel. It takes about 10-20 mins to install these. The other option we use is powered speakers, I prefer these, but they take more effort to install, as they need to be cabled in. ACTIVE30-SLV - PULSE - SPEAKERS, 5" 30W ACTIVE SILVER | CPC or ACTIVE40PRO-BK - PULSE - ACTIVE SPEAKERS, 40W RMS, BLACK | CPC All options cost a similar amount, so it depends on how much work is involved.
  22. Don't know about legalities in your country, but we had a unit setup in our staff work room that staff could use as they needed. As others have mentioned, the success rate is low. pre-recorded commercial tapes normally can't be copied as they mostly have copy protection. I believe it would be illegal to circumvent this in most western countries. Personally, I would always recommend trying to find a digital copy, as it takes far less time, and the quality will almost certainly be better.
  23. How about Crashplan? Its free if you have another computer to backup to.
  24. I think in theory, you can rotate most html elements in css 3. Also, have you remembered to apply your css to the print media as well as the screen media? Personally, I worked round it by setting the option in the browsers print dialog box. Not ideal, but works for us. Edit: Is this any use? Please see section 13.2.2. http://www.w3.org/TR/1998/REC-CSS2-19980512/page.html
  25. We do something very similar with our id cards. They are all printed off of a custom web app via a web browser. We use a rio tango 2e card printer. I think most are seen as a standard windows printer by the PC. You just need to set the page size and orientation correctly.
