[CentOS] Re: Clarification

Snowman,

up2date and yum both work on top of or maybe "in cooperation with" the rpm package management system. So, if you like using one or the other to do your updating at a given time you can use either one and they won't get confused since they both store/read information from the rpmDB.

Yum uses metadata about a repository to know what is going on, what updates might exist, etc. You can use "yum list updates" to see what needs to be updated. Some people put a "yum list updates" and then redirect it to mail to them in their daily cron so that they know if they have updates rather than using the up2date applet.

When you start yum it goes to the repositories in your configuration files, pulls down the metadata from those repositories and then parses through it looking for updates, packages to satisfy dependencies if there are updates, and other fun stuff like that.

None of the files for CentOS (unless you changed something) from from anything RH related. I assume you know how that all works and said "RH" where you meant "CentOS"...

List,

Being pretty new to CentOS and such, can someone answer a couple of

questions about yum and up2date? I think I got the basic info, but I'm a bit confused about what does what.

I configured yum to use the dag repo (I think) but now and then, I

get the red circle from up2date stuff on the upper menubar. I have been using the up2date function to grab the latest bits when indicated something is available. I don't have yum running nightly as a cron job either. Now, what is the difference in using the up2date vs. yum? Should I be using yum exclusively to do updates, and if so, how does it know there are updates available? Are the files coming from the RH update site the same as would be avaliable via yum?

Sorry if this is a newbie question, but while the machine is down

waiting on the new mobo, I figured I could do a little brushing up on things I don't fully understand.

Thanks..
