Heh, thats what I thought! Oh well, at least it's not my data, i'm not stupid enough to use RAID 0!

Yeah I know there's no fault tolerance in RAID 0, just wondering what the chances are that there's some data on the two good drives?

I've been asked if I can look into recovering some data from a broken RAID 0 array. Has anyone has any success in doing this? They're not overly bothered about the data, so spending hundreds on getting a data recovery company to do it is out of the question. There's 3 drives in the array and one is completely borked. It's proper hardware based RAID just for some stupid reason they didnt go with RAID 5! Am i right in thinking every file is spread across the 3 drives or might 2 of the drives have some complete data? Active File Recovery for Windows says it can reconstruct a broken RAID 0 array and could recover some data, has anyone used that or has anyone got any suggestions?

Ahah, was just wondering as you're around the same area I am. Nevermind!

Yes yes!

Microsoft has a useful utility called File Server Migration Toolkit, available from here. It will move files/shares whilst preserving permissions and share names, i've not used robocopy so i don't know if this does exactly the same thing!

You do mean MRBS don't you? Have you looked at this? You'll have to give it details of your AD setup. If you're going to use the auth_ldap method you'll also have to build/enable this in php. More specifically: LDAP Authentication ------------------- There are currently three methods for doing LDAP authentication, auth_ldap, auth_ldap.pl, auth_ldapsearch.pl. The preferred method, auth_ldap, uses the LDAP functionality built into PHP and is described here. The other methods use the 'ext' authentication method and described further on in this file. This method can be used by setting config.inc.php as follows: $auth["type"] = "ldap"; Also you will need to change the section: # 'auth_ldap' configuration settings # Where is the LDAP server $ldap_host = "localhost"; # LDAP base distinguish name # See AUTHENTICATION for details of how check against multiple base dn's $ldap_base_dn = "ou=organizationalunit,dc=my-domain,dc=com"; # Attribute within the base dn that contains the username $ldap_user_attrib = "uid"; This method will attempt an authenticated bind to the ldap server using the supplied password and a distinguished name, which is formed from the base distinguished name, the user attribute and the user name. This method supports multiple $ldap_base_dn entries and $ldap_user_attrib values. The authentication is attempted with each base dn in turn until it succeeds or it fails to authenticate the user. Multiple base distinguished names with the same user attribute for each base dn: # 'auth_ldap' configuration settings # Where is the LDAP server $ldap_host = "localhost"; # LDAP base distinguish names $ldap_base_dn[] = "ou=People, o=myCompany, c=US"; $ldap_base_dn[] = "ou=Administrators, o=myCompany, c=US"; # $ldap_user_attrib = "uid"; Multiple base distinguished names with the option of different user attributes for each base dn: # 'auth_ldap' configuration settings # Where is the LDAP server $ldap_host = "localhost"; # LDAP base distinguish names $ldap_base_dn[] = "ou=People, o=myCompany, c=US"; $ldap_base_dn[] = "ou=Administrators, o=myCompany, c=US"; # $ldap_user_attrib[] = "uid"; $ldap_user_attrib[] = "cn"; Note: if you use the latter configuration then an equal number of base dn's and user attributes must be specified or authentication will fail.

Almost exactly what I use, if i'm doing it with PATA drives I make sure the source drive is on the Primary Master (hda) and the destination is on the Secondary Master (hdc) which speeds things up and I also make the block size 128MB. dd if=/dev/hda of=/dev/hdc bs=128M But make sure the machine you're using has plenty of RAM when you get to bigger block sizes.

I know this is OT, but you're not on the Northern Grid for Learning are you webman?

We're using Blackboard at the moment, its expensive, but polished (unlike Moodle) and does everything we need it to do. It's expandable by using Building Blocks to add functionality like plagiarism checking (which is damn good, checks sentences against google, work already handed into the system and other sources), automatic sms messaging to say work is due/marked etc I've heard that FrogTeach is the dogs knackers! Not had a chance to look at it for myself, our RBC is having a Regional Learning Platforms meeting in March which it's going to be demoed at though.

I try to keep them as far away as possible! It does come in handy for when the footballs on and we've now got a HD projection set up in there with a screen the size of the back wall, the xbox 360 looks mighty fine on it

I just use "shutdown -i" to invoke interactive mode and select a group of machines by name to shutdown. Doesn't take too much time to do! I've got a problem with WOL, our switches discard the MAC table after a couple of hours so in the mornings there's no MAC address info on the switches so WOL doesn't work Really need to look into that!

We use Scotia for all our AV stuff. Fantastic and professional! They installed a bespoke auditorium for us, with VC, rear projection screen, interactive whiteboard, visualiser, lectern with inputs for laptops etc, induction loop, Sky Digital, DVD, VHS, Wireless Mics, Speakers, all remote controlled with a Crestron unit.

Depends on how much money you have! The iMac's are perfect for schools, coupled with Final Cut Studio the kids can learn the basics of editing with iMovie then go onto Final Cut Studio. If they like that they can move onto Final Cut Pro or Avid after school.

The good old days!

Might i suggest using the tag in future

Whoops, obvioulsy not a big enough link

How about a page that uses google maps to show where all us edugeek users are?

Their web site?

If you're just using MAC address authentication on your wireless LAN the packets can still be sniffed with something like Ethereal as they are being transmitted unencrypted. This means all manner of data could be looked at by anyone! Yes MAC addresses can be spoofed fairly easily, but remember the attacker needs to know the MAC addresses on the allowed list first. At the very least I would encrypt the Wireless LAN with WEP and use MAC filtering! WEP does have weaknesses though, with enough time the key can be cracked, the last time I tried it though it took almost 2 weeks of packet sniffing! Still it is possible, look at what other encryption methods your AP's offer, something like WPA2 would be better as long as all your clients support it!

Well i've always called it SAV! Anyway, after reseating the RAM and CPU's nothing bad has happened today.. yet!

I have to say that overall I'm happy with our Dell kit, the only problem is when something goes wrong I have to go through their troubleshooting crap on the phone for half an hour before they send someone out. Me: The PSU's broken Dell: Can you remove the power cable for 30 seconds then try again Me: Already done that Dell: Does it work now? Me: No Dell: Have you tried a different power cable Me: Oh how stupid of me, I should have thought of that first Oh and refuse the first price Dell give you, my rep knocked 16k off a quote for almost 50 workstations just because I said it was too expensive a few times.

Exactly what I found, I ended up just putting a simple rule on the firewall and Symantec Web Security does a good job of blocking the web based sites.

When I say SAV I mean Symantec Antivirus, isn't it Sophos that has the EM Library? Gonna keep an eye on the server again today, I think it might be happening at times of peak load like lesson change over.

Hmm, thought I had a machine that I could put this RAM in but I don't I've moved the RAM around and reseated the CPU's, I'll see how it gets on.
