System: ntp version 3.4
Patch #: 12
Priority: 
From:
Description:

Had my head on backwards with a reversed test in the clockhopper avoidance
code.  Need to switch to the first selected clock when its stratum is lower
than the current sys.peer.


Repeat-By:

Fix:	From rn, say "| patch -p -N -d DIR", where DIR is your ntp source
	directory.  Outside of rn, say "cd DIR; patch -p -N <thisarticle".
	If you don't have the patch program, apply the following by hand,
	or get patch (version 2.0, latest patchlevel).

	After patching:
		make
		make install

	If patch indicates that patchlevel is the wrong version, you may need
	to apply one or more previous patches, or the patch may already
	have been applied.  See the patchlevel.h file to find out what has or
	has not been applied.  In any event, don't continue with the patch.

	If you are missing previous patches they can be obtained from me:

	Louis A. Mamakos
	louie@trantor.umd.edu

	You can also get the patches via anonymous FTP from
	trantor.umd.edu.
