I was just wondering if anyone had some really cool uses for Ruby in Systems
Administration. Some examples of what I would consider to be really cool is
stuff like using drb or webrick to poll system status, gather inventory
information, etc. Useful ways to interact with multiple systems. Ways to
push system changes out to hundreds of servers. Etc, etc… I know there’s
some stuff on the wiki ( http://www.rubygarden.org/ruby?RealWorldRuby ) as
well.
Though not exactly what you’re looking for, Rconf is an example of a
working system administration framework, take a look at Alexander
Bokovoy’s slides from EuRuKo 2003:

You could try to reach jfontan at #ruby-lang (irc.freenode.net, European
timezone). He’s using drb to monitor a big cluster and might want to
comment on his experiences.

It need some improvements, but at the moment it has been very useful to
take control of 800 machines.
*ix → net/telnet, sockets
win → drb
If somebody is interested on it, I will put it in raa/rubyforge.

Nifty! I was actually planning to look into webrick and write this over
the weekend, as a quick way of sharing a directory with someone. You
should put that up somewhere on the wiki.
Well, I wrote a little script called “quickhttpd” which fires off
a web server on some high port which serves up documents in the
current directory. This is very handy for all those software

BTW: I sent this post for 1st time 1hr ago…let see if it works now
