Suspending and resuming Dynamips

As someone who travels often, and always looking to make use of the travel time, I was pleased to find that I can suspend and resume the Dynamips routers. This saves me battery on longer trips, or lets me have more CPU when I running other applications such as Parallels / VMware to give me some Microsoft Visio joy. iTerm sessions are not terminated by doing this, they just don’t show any data until you resume the sessions.

Configuring iTerm for Dynamips

To get started with my lab faster I use iTerm to prepare a full set of possible sessions. This post walks through how to do this which should help you to get started faster. Also some keyboard shortcuts.

Unzip Cisco IOS images for Dynamips

I have a directory ‘dynalab’ in my ‘Documents’ where I have put ALL my Dynamips / Dynagen related files. I created a directory there which has all my IOS images, this makes more sense to my mind. Makes it easier to backup.
