Cisco 3560, 3750 archive command to install or upgrade IOS via tar file

Some newer L3 Cisco switches are now happier if you use the ‘archive’ facility to manage images.
If you only want the IOS, and not the web interface and so on, use the /imageonly flag.
From the Cisco release notes :
For example:
Switch# archive download-sw /overwrite tftp://

Check the release notes or command reference (or in-exec help) for further options.

This apparently does away with ‘boot system statements’ as well, as you can see if you run ‘show boot’ on the switches. The image set by your ‘archive’ command becomes the active image on reboot.  I’m not sure what happens if you have both explicit ‘system boot <blah>’ statements and the automatic IOS precedence setting configured via the fancy archive method.

DreamPie Python editor

I’ve been trying out the DreamPie python editor, and it looks promising.  It’s free, GPLv3.

I just added an entry for it at :

  • DreamPie (sourceforge)
  • Works on Windows, Linux and Mac. (Mac support requires MacPorts .)
  • Interactive shell with history box and code box, auto-completion of attributes and file names, auto-display of function arguments and documentation. Keeps your recent results, provides session history saving (optionally in HTML), interactive plotting with matplotlib. Extremely fast and responsive. GPL3 .

interesting: launchpad recipes for merging branch updates into PPA’s

OK, this sounds very cool ; still in development:

What does this really mean?

Lets say you want to have a daily build of a project, like gwibber. You would then create a recipe that uses trunk as a base branch, merge in the packaging info, and say “Please build this every day into my PPA”. And Launchpad will.
