KB ID 0001170 Dtd 26/03/16 Problem I have a love hate relationship with GNS3, I appreciate it’s brilliant, (when it works).

But when I try to do simple things, like connect my projects/labs to the internet and it’s massively overcomplicated I get pretty exasperated. With Windows this is easy, (I’ve...

KB ID 0001160 Dtd 16/02/16 Problem GNS3 had nagged me the last few times I tried to use it about upgrading, so I downloaded and installed the update and it stopped here; Could not find a VM named ‘GNS3 VM’ is it imported in VMware or Virtualbox I use both VMware Fusion and Virtualbox.

Route Summarisation with EIGRP

KB ID 0001149 Dtd 31/01/16 Problem I’ve already written a post that lets you calculate a route summarisation.

To demonstrate I’ve built the above network on GNS3, there is a loopback interface on the routers for each of those networks....

KB ID 0000927 Dtd 15/03/14 NOTE: THIS ARTICLE IS FOR THE OLD VERSION OF GNS3 GO HERE FOR THE NEW ONE Problem I dip into GNS3 every so often, (depending on what I’m working on).

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. Solution Note: At time of writing he...

GNS3 – Assign an IP Address to Linux Microcore QEMU Guest

KB ID 0000932 Dtd 31/03/14 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...
