Recall these were never meant to live very long in the first place.
With the internal restructuring completed and the TCP/IP protocols integrated
with the prototype IPC facilities, several simple applications were created to
provide local users access to remote resources. These programs, rcp, rsh,
rlogin, and rwho were intended to be temporary tools that would eventually be
replaced by more reasonable facilities (hence the use of the distinguishing "r"
prefix). This system, called 4.1a, was first distributed in April 1982 for local
use; it was never intended that it would have wide circulation, though bootleg
copies of the system proliferated as sites grew impatient waiting for the 4.2
release.
