Upgrade of fpmmm tar ball from 1.x to 2.2.1

There are some changes in the configuration file (fpmmm.conf):

  • The access rights should be change as follows: chmod 600 /etc/fpmmm.conf
  • The key Methode was spelled wrong in the configuration file. It was renamed to Method.

Upgrade with DEB/RPM packages should happen automatically. For tar balls follow this instruction:

$ cd /opt

$ rm -f fpmmm
$ ln -s fpmmm-2.2.1 fpmmm
