NTPd does not start on FreeBSD 12.0

Posted on by Andy

NTPd quits with following error:

Starting ntpd.
su: unknown login: ntpd
/etc/rc.d/ntpd: WARNING: failed to start ntpd

Just enter following commands to rebuild master password database and remove old ntpd.pid file:

# /usr/sbin/pwd_mkdb -p /etc/master.passw
# pkill ntpd
# rm /var/db/ntp/ntpd.pid
# service ntpd start

Here a simple howto to prepare the connection:

  • Install MacPorts
  • Insrall XQuartz
  • Install virt-viewer
    # sudo port install virt-viewer
  • Create SSH id on OSX (used for passwordless login)
    # ssh-keygen
  • Then copy this key to your remote server (~/.ssh/id_XXX.pub)
    # ssh-copy-id root@server.machine

Now you can connect with the following URL:

# virt-viewer -c qemu+ssh://root@server.machine/system?socket=/var/run/libvirt/libvirt-sock
