It appears that the ntp.conf file in the xntp3 package
shipped with RH 6.0 contains a stray character. In previous
versions of Red Hat, the file read, in part,
fudge 127.127.1.0 stratum 0
Now, however, it reads:
fudge 127.127.1.0 stratum 10
Nonetheless, the comment block above this line continues to
speak of using stratum 0. I suspect the new version of the
file to stem from a typo.
If I'm wrong, the comment should probably be updated to
reflect (and perhaps explain) the change.
The change was made so that machines without a reference clock
did not inadvertantly start honking NTP at stratum 0. The comment,
not the configuration, is incorrect.
In order to configure and use xntp3 correctly, see the URL
http://www.cis.udel.edu/~ntp. Basically you will need to find
a reference clock server that will be added to ntp.conf as
Red Hat can't supply a default refernce clock server in ntp.conf
because of the number of installed Red Hat systems.
