In my very first post here at Computerworld I comment on the use of RSS feeds as an administration technique (RSS as an administration tool).
It caused quite a stir at the time amongst fellow bloggers at CW and how useful and practical that was. I've finally been able to put that into more detail through a tutorial at IBM's developerWorks site. Since I posited the thought here first, I thought I should let the readers here know about it too.
You can get some summary information on the tutorial here, or jump straight to the tutorial: Use alternative methods to manage and monitor your UNIX servers.
