Apart from its home platform OpenBSD, PF is also installed by default in FreeBSD starting with version 5.3, in NetBSD from version 3.0, and appeared in DragonFly BSD from version 1.2.

Famous quotes containing the word ports:
“I need not tell you of the inadequacy of the American shipping marine on the Pacific Coast.... For this reason it seems to me that there is no subject to which Congress can better devote its attention in the coming session than the passage of a bill which shall encourage our merchant marine in such a way as to establish American lines directly between New York and the eastern ports and South American ports, and both our Pacific Coast ports and the Orient and the Philippines.”
—William Howard Taft (1857–1930)
“When its errands are noble and adequate, a steamboat bridging the Atlantic between Old and New England, and arriving at its ports with the punctuality of a planet, is a step of man into harmony with nature.”
—Ralph Waldo Emerson (1803–1882)
“O polished perturbation! golden care!
That keep’st the ports of slumber open wide
To many a watchful night.”
—William Shakespeare (1564–1616)
