The networking loopback interface is not correctly loaded in the Redhat 6.0 package, as well as in the 5.2 version, which causes apache and any other packages that depend on the loopback interface to function incorrectly. I solved this problem by simply adding in the appropriate entries in my /etc/sysconfig/network-scripts/ifcfg-lo file. The only thing that was in there was the BOOTPROTO=none flag. I discovered this when I tried to ping my lo interface and my eth0 card and received no packets. I'm not sure if this is a real bug, as I have pretty much "bastardized" my entire system by mixing packages from different releases, but on my 5.2 box, was a regular install, that I have yet to touch. Please check this out and advise me further. Kevin McConnell
Unable to relicate this in the test lab on either 6.0 nor 5.2 systems. Both have complete ifcfg-lo files by default at install.
