I don’t always need a full Linux VM running when all I want to do is ping or traceroute between two hosts on the network, this is where Virtual PC Simulator (VPCS) comes into play. VPCS is a lightweight PC simulator that has a basic set of network commands such as ping, traceroute and telnet. It does not consume the CPU and memory resources that adding another router or VM would use. VPCS can simulate up to 9 separate PC at a time. Continue reading Adding VPCS to GNS3 v1.1

I recently got a new laptop at work. It has one major downside, it only has 4GB of RAM which is soldered straight into the motherboard and therefore can not be upgraded. Also 500MB of the RAM is reserved for the GPU, so I only have about 3.5GB of useabe RAM. This is fine for running my day to day applications for work, but does not leave much wiggle room for running GNS3.
Luckily I work for a hosting company and we have quite a few servers lying around doing nothing. I managed to get hold of a decommisioned server with 2 quad core processors and 48GB of RAM, perfect to run a remote GNS3 server on. We mainly use Centos and since it is not an OS I am familiar with (I mainly use Ubuntu) I decided to give it a go and try something new. In this post I will run through the steps I went through to get GNS3 sevrer running on Centos as well as setting up the GNS3 GUI to connect to the remote server.
