Let’s start in the GNS3 WorkBench environment by opening the Desktop shortcut Standard Layouts. If you can’t, then reading my previous posts ( 1) & ( 2) may help you troubleshoot. You will need to have your Host PC set up to obtain an address automatically for this to work for the eth0 address. You might want to check that your Host PC and guest OS (Ubuntu) can ping each other on these addresses. Check the ip address of your Ubuntu interfaces using the ifconfig command: ifconfig | grep -A 1 eth.Įth0 Link encap:Ethernet HWaddr 00:0c:29:d1:e5:82 Have the GNS3 Workbench VM running, and bring up a konsole command prompt. If you have been following the previous articles, you will have a Windows PC host OS and your Ubuntu Guest OS with IP addresses something like: Host PC Interface IP address Your host PC will need its Ethernet port connected to some physical device to ensure that it is up. It is important that you configure your GNS3 WorkBench Virtual Machine so that your first Virtual Network Adapter is Bridged to your Host PC as explained in my previous postįor the remainer of this article, I’ll assume you are running GNS3 WorkBench v5.6 within a VMware Player (v3.1.4) environment on a Windows based Host PC. It was also while writing this article that I realised that GNS3 Workbench v5.6 was configured with the primary interface (eth0 on Ubuntu) linked to non-existent host interface. ![]() The emphasis here was to show you that the interfaces on your guest OS (Ubuntu) are determined by the Network Adapter Settings of your VMware Player. The second article dealt with linking your Virtual Machine’s adapters to your Host PC within the Ubuntu/GNS3-WorkBench environment. In this article, I explained the relationship between your Host PC and the Virtual Interfaces that VMware creates when you install VMware Player, and how to use vmnetcfg.exe. The first article was a tutorial on VMware Interfaces as they relate to your Host PC. This is the third and final article of a series. If you’d like to learn about that relationship, then read on. ![]() Once you become familiar with GNS3, the thought soon strikes – how can I get my PC to talk to the routers in my GNS3 configuration? Since GNS3 WorkBench operates within a virtual machine, the process is a little more complicated than running GNS3 directly on your PC because you have to understand the relationship between your Host PC, your Guest OS (Ubuntu in this case) and the virtualised devices in GNS3. ![]()
