Damien Millere4340be2000-09-16 13:29:08 +11002 * scp - secure remote copy. This is basically patched BSD rcp which
3 * uses ssh to do the data transfer (instead of using rcmd).
Damien Miller4af51302000-04-16 11:18:38 +10004 *
Damien Millere4340be2000-09-16 13:29:08 +11005 * NOTE: This version should NOT be suid root. (This uses ssh to
6 * do the transfer and ssh has the necessary privileges.)

12 * software must be clearly marked as such, and if the derived work is
13 * incompatible with the protocol description in the RFC file, it must be
