[ILUG] Some questions about uname, hostname

[Colin Rooney]

one04 or dub04?
man uname will tell you that one04 is the network "node" name
hostname returns the hostname ... the are usually the same but must not be.
No idea why they as they are on your machine... I guess you set them so? :)

google hostname nodename and you will find lots of references explaining the
difference and where values come from.
