GNS3 – Network Cards Are Missing
KB ID 0000964 Problem Like most techies, I am always fiddling with things. One of my mottoes is “If you never break anything, you never learn how to fix things”. So after messing around with the networks in VMware Workstation (What I typically use for connecting GNS3 to either real machines, or the outside world). I lost the network connections in GNS3 and could not get them back. Seems like any new NICs that you add are...
Dell PowerEdge – PERC RAID Card Importing / Using ‘Foreign’ Disks
KB ID 0000639 Problem I bought some SAS disks from eBay to go in my Power Edge 2900 Server, and scratched my head for a while trying to get the PERC RAID controller to use them.

Dell DRAC 5 – ‘Error when reading from SSL socket Connection’
KB ID 0001062 Problem Ages ago I did an article on how a Java update has stopped me getting access to the DRAC 5 controller on my Power Edge 2950. Well I had more problems this week trying to get on from my MAC. Solution The problem is, Java have pretty much blocked communications with SSLv3 (in light of the recent Poodle attack scares). Which is fair enough, but it’s not helping me get on my server that’s 50 miles away!...
