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. I could only see them marked as ‘Foreign’. Probably because they did not have their original config ‘wiped’ off them before I bought them. Solution 1. Boot the server, Press CTRL+R when prompted, then press ‘C’ to enter the...

GNS3 ASA Error – ‘ASDM did not recognize device model ASA5520’

KB ID 0001028  Problem Apart from the fact that’s an appalling spelling of recognise, I got bitten by this last weekend. I don’t use the ADSM as a rule so it would not normally be a problem, the only thing I do use the ASDM for is certificates, (it’s just easier). Solution Last time I saw an error like this I had to use a fiddler script to embed the firewall model in the https traffic, however now there’s a...

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!...

GNS3 Cannot Connect Network Interfaces when running on VMware vSphere

KB ID 0000671  Problem I have plenty of real ASA firewalls to play with, but it’s getting round to re-certification time, so for ease I thought I’d run up a Virtual ASA on my vSphere 5 box just for testing and breaking. However no matter what type of Virtual Network adaptor I used (vmxnet3, e1000, etc) I could not connect to the virtual firewall. Solution 1. Firstly make sure you actually have an IP address in the correct...
