okay, lets say you have a basic understanding of linux. and you find out you need to have the same uid and gid between a couple of servers for say NFS sharing.

AND you need to update files after the change.

I have decided to make a fundamental change, in the way i post articles to this site. from now on i will use a pubdate method. giving me time to think and write something, as well as double check it. the new pub date is Mondays.

in other news i have decided to write a look into basics of Linux. things every Linux admin should know. really basic things that even if you just administer a desktop you know what is going on. and can do basic trouble shooting.
