Freecom Tough Drive – Remove Password and CD Drive
KB ID 0000403 Problem I’m a big fan of Tough Drives! My old 260GB was getting a bit full – so I bit the bullet and replaced it with a shiny new Tough Drive Sport 750GB. As it comes with password protection I turned this on – fast forward to the next day (this morning) and it’s bugging the hell out of me. I mailed the nice folk at Freecom and within twenty minutes they mailed me back with instructions to...
GNS3 – Initial Setup, Adding Routers, Hosts, and ASA Firewalls
KB ID 0001079 Problem I dip into GNS3 every so often, (depending on what I’m working on). And each time I install it, I spend just as long remembering how to set it up, as I do using it! So, if for no other reason than I can use this page as a reference in future, here’s how to get it up and running.</p? Solution Note: At time of writing the latest version is 1.3.6</p? 1. Download GNS3, I usually accept all the...
GNS3 – Assign an IP Address to Linux Microcore QEMU Guest
KB ID 0000932 Problem The whole point of having these guest machines is for testing communications, putting an IP address on them so you can ping things, is a pretty basic step. Solution 1. Console in, and execute the following commands, obviously change the IP addresses to the ones you require. sudo su ifconfig eth0 10.10.10.10 netmask 255.0.0.0 up route add ip default gw 10.10.10.1 route add default gw 10.10.10.1 Related Articles,...
GNS3 – Routers Lose their Certificates When Restarted
KB ID 0000955 Problem I was doing some work with PKI and routers today, and after spending ages enrolling all my routers for certificates, I thought I’d save my hard work and return to it later. When I started the project up again, I was less than happy all the devices certificates had ‘Disappeared’! Solution This is default behavior, to change this select Edit > Preferences > Dynamips > Locate...
GNS3 – Error ‘ghostsize is to small for device’
KB ID 0000935 Problem While doing a quick lab in GNS3, I tried to add NAT to a router, and it fell over with the following error; R3(config-if)#ip nat outside % NBAR ERROR: parsing stopped % NBAR Error : Activation failed due to insufficient dynamic memory % NBAR Error: Stile could not add protocol node %NAT: Error activating CNBAR on the interface FastEthernet0/0 R3(config-if)# *Mar 1 00:01:11.655: %SYS-2-MALLOCFAIL: Memory...
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...
Accessing Dell ‘DRAC’ Fails – ‘DRAC5 Console Redirection Client Unable to launch application’
KB ID 0000918 Problem After I got a new laptop, I attempted to connect to my test server and was greeted with this error. Application Error Unable to launch the application Name: DRAC5 Console Redirection Client Publisher: Dell Inc Location: {ip-address}:443 So I hit the details tab and got this, Error: Missing required Permissions manifest attribute in main jar: https://{ip-address}:443/plugins/vkvm/avctDRAC5Viewer.jar Solution...
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!...
