Oh, you want to upgrade specific packages from those in 2.1 to those used in 3.0? Yes, you'll have some major problems--mostly having to do with needed prerequisites. If you are going to update 2.1, you need to get an update entitlement from Red Hat (they're not free), then you can use up2date to keep the machine current with the latest 2.1 stuff. >> I do want to upgrade the whole OS from AS 2.1 to AS 3.0. I was just trying to see if I can "upgrade" to AS 3.0 by updating all the RPM's. Apparently, that did not work too well. With this saying, does it mean that installing a AS 3.0 package (or any packages) to AS 2.1 can be done if I can resolve the dependencies? If you want to upgrade from 2.1 to 3.0, do what I said above. Remember, NONE of Red Hat's "Enterprise" Linux releases (ES, AS, EL, WS) are free. You get 1 year of free updates when you buy, but after that, you must renew the update entitlement. If you want free Linux, you have a number of choices. The closest to Red Hat Linux are Fedora Core 1 (FC1) and Fedora Core 2 (FC2). FC1 was _going_ to be Red Hat Linux 10 before they decided to go the "pay to play" route. FC2 is the latest release (using the 2.6 kernel and X-Org's X Windows implementation rather than XFree86). I use it a lot. Due to the 2.6 kernel, there are fewer drivers available for oddball hardware but this should improve over time. It doesn't bother me as I'm considered to be something of a geek. >> Thanks for the explanation. I was wondering what FC1/FC2 are? (heard it a lot, thought this verison is more of a "developer" verison of Redhat). If being a "geek" can be as knowledge as you are, I sure hope I can be a "geek" one day.... :) There are other free ones such as Mandrake (more geek-oriented), Debian, GenToo and a whole bunch of others. There is a free version of AS3 out there called "WhiteBox" which is built from Red Hat's AS/ES3 source RPMs. I've never used it and don't know how easy it is to install or upgrade from AS2.1 to it, but once it's up, it's essentially ES/AS 3.0. >> Thanks, Rick. You have always been a great help in answering all the quesitons I have. ---------------------------------------------------------------------- - Rick Stevens, Senior Systems Engineer rstevens@vitalstream.com - - VitalStream, Inc. http://www.vitalstream.com - - - - I won't rise to the occasion, but I'll slide over to it. - ---------------------------------------------------------------------- </BLOCKQUOTE></DIV>
