I’ve recently been writing some auditing scripts for IOS switches, so have been trying to test it on as many devices as I can, well that’s a lot of work setting up routing etc; so I’ve installed Dnyamips and Dynagen, the Cisco emulators.

They’re not as polished as QEMU for example, in that there’s a bit of a naff command you have to run as root to start a daemon which isn’t particularly stable, the CPU usage goes through the roof until you manually tweak it and IP doesn’t work on localhost unless you set up a tap interface. They do the job though – I’m currently emulating a 3745 and 7206.

I’ve also upgraded the blog to WordPress 2.9, which went OK, except some moron has left a load of Windows ^M characters throughout the UNIX download.
