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.
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.
