[chrony-users] chrony-2.2-pre1 released

[ Thread Index | Date Index | More chrony.tuxfamily.org/chrony-users Archives ]

The first prerelease for chrony-2.2 is now available.

The most significant change is support for the command and monitoring
protocol over Unix domain socket, which replaces authentication with
the command key. This simplifies the configuration and it should also
make the protocol more secure as only few monitoring commands can now
be allowed for remote hosts. Users that need to configure chronyd
remotely or locally as an ordinary user should consider using ssh
and/or sudo to run chronyc on the server under the root user or the
user under which chronyd is running when configured to drop the root
