This post looks at installing GNS3 on Snow Leopard and has a number of screenshots and some tips on making it go well.
Dynamips and dynagen are well behaved programs most of the time. Occasionally I am configuring a feature or two that causes IOS to crash (most recently I was configuring MPLS and redistribution on c2600 IOS which got really busted).
Then I noticed that my hard drive didn’t have a lot of free space….
I am often find myself needing to stop, make a configuration change to Dynagen, and then restart. To make sure I don’t miss anything I go to every screen and write the configuration.
In iTerm, there is the ability to send the same command to all screens at once, excellent!
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.
I wanted Dynamips to act more like the way I think and it keeps on opening multiple terminal windows but I like to use iTerm.
