- System: ntp version 3.4
- Patch #: 8
- Priority:
-
- From:
-
- Description:
- Update suggested tickadj values in the README file.
-
- The syslog message for peer selection had to be moved to account for the
-
- anti-peer flapping code just installed.
-
- Minor cosmetic changes and removed dead debug code from ntpd.c
-
-
- Repeat-By:
-
- Fix: Either ftp the new /pub/ntp.3.4/ntp-test.tar.Z file, or apply
- this patch.
-
- 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 depend
- 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.

- This step is optional; new algorithms will allow you to

- History:
- + 4/8/89
- + Changes to the ntp_proto.c module to supress peer switching when the
- + dispersion between the newly selected peer and the currently selected
- + peer is "small." A new configuration option, NOSWAP, has been added
- + for use on Ultrix systems which can lock the ntpd process in memory;
- + very desirable for diskless workstations. peer.reach is now not
- + cleared in the clear() procedure. The stat.pl perl script can now
- + handle syslog records which span a month boundary correctly. We're
- + getting real close to a "blessed" version now.
- +
- 3/29/89
- A few fixes, clean up of unused #defines in ntp.h. The receive()
- procedure is now table driven per the 26 March 1989 draft of the
