Remote Process Execution

From Wikipedia, the free encyclopedia
Jump to: navigation, search

rexec has the same kind of functionality that rsh has : you can execute shell commands on a remote computer.

The main difference is that rexecd authenticates by reading the username and password (unencrypted) from the socket.


Same as rsh: sends unencrypted information over the network, including passwords.[citation needed]

Port number[edit]

rexec uses well-known port TCP 512.
