Display IP address of system

Good idea Bryce!

Actually, though, update-motd is quite simply the generic framework by which such information is presented.

Rather, I think this information should be gathered and presented as part of landscape-sysinfo!

:-Dustin

Herewith a first attempt at a sysinfo/networks.py plugin, which delivers this info to the user landscape-sysinfo .

I have a feeling the code is not exactly portable, but it works for me on Ubuntu 8.10 Intrepid i386. I'd be interested to learn of of a more portable way to do this in Python.

The code in networks.py that enumerates network interfaces and grabs the IP address of a given interface is based largely on from the ActiveState "recipies" by Paul Cannon, which were provided under a MIT copyright at

  http://code.activestate.com/recipes/439093/ and http://code.activestate.com/recipes/439094/

Basically the patch just adds the Networks class to the list of classes in deployment.py and the networks.py file implements that class, adding a Header for each active interface.

Sample output of landscape-sysinfo with this plugin in place is:

 System load: 0.45 Processes: 125
  Usage of /: 37.5% of 74.20GB Users logged in: 1
  Memory usage: 70% IP of lo: 127.0.0.1
  Swap usage: 4% IP of eth0: 192.168.1.100

Jonathan:

Sorry for ignoring your patch for so long. This was an oversight on
our part. I haven't actually used it, because we now have support
to get information about network devices (that is 32-bit and 64-bit
friendly). I noticed the bug this evening because David was kind
enough to tag it, so I took the opportunity to implement a sysinfo
plugin that presents the same UI you had in your patch.

All landscape-client branches need two reviews before being landed,
so if you feel like checking it out, please leave any comments you
might have on the related merge proposal. Thanks again for the
patch and sorry for not giving it attention for so long.

David:

Thanks for tagging Jonathan's patch!

The current implementation does not attempt to list any IPv6 address for the enumerated interfaces. I consider this a bug. It is arguable to only show global addresses (i.e. omit [fe80::]).
