The ramblings of a computer geek
I’ve been wrestling with a course restore problem on Moodle 2.4.2 and Moodle 2.5. Basically you can take a course backup fine, but when trying to restore it, it will timeout, and fail to restore the course at all or may only restore a small segment of it. Of course it fails, with no entries […]
More...I’m not a huge fan of Moodle, its basically a unsupportable mess. However the price: Free, is very appealing in the times of no money and so we are stuck with using it. One of the nice features is that of SSO using NTLM authentication. We use Microsoft Windows 2008 R2 with IIS 7.5 and […]
More...I was setting up an SSL certificate for secure administration on a Barracuda Networks Load Balancer appliance. Normally Barracuda’s products are very easy to everything, but the Secure Administration certificate install was a bit of a head scratcher. The documentation on their support site seems to miss out a key step of the install, it […]
More...Something I’ve done recently, the switch has been in for over a year, but was put in, in a hurry, and we’d never got round to finishing off the configuration fully until now. It has two processor supervisor blades, but its always been running in RPR mode, as we now run VMware ISCSI traffic through […]
More...I’m only going to show the juicy bits of the config. I.e. the bits that refer to the routing, EIGRP or IP SLA stuff. A user at Site A in normal use should see two default routes to the Internet, one being their local default route, and then the Site B default route, with a […]

There are some security implications you need to be aware of first, Cisco’s document on it is a good read:http://www.cisco.com/c/en/us/support/docs/switches/catalyst-3750-series-switches/91672-catl3-wol-vlans.html Also download Solarwinds Free Wake On LAN tool, its a good one to use to test […]
More...Tapes are basically sticky tape and rust, therefore they are liable to break especially your weekly rotation ones, just because they get wear and tear. When this happens and the tape is no longer able to be used, we need to remove it from DPM to stop it appearing the in the tape request reports. […]
More...This is not as easy as it is on a Cisco 3750 or 6500 series switch but once you know how its not too bad. Step 1 Copy the new IOS image to the switch, you need to use: copy tftp: bootflash: (Notice its not “flash:”, first of the oddities.) Step 2 verify the image […]
More...PROBLEM Attempt to install Tracing for IIS failed with error code 0x80070643. POSSIBLE CAUSE There are a few causes to this problem, in my case I had Shared Configuration setup, if you try to install tracing with shared configuration setup it will fail. This isn’t the only cause so this solution may not work for […]
