5260325f | 3 | * scp - secure remote copy. This is basically patched BSD rcp which uses ssh |
4 | * to do the data transfer (instead of using rcmd). | |
6ae2364d | 5 | * |
5260325f | 6 | * NOTE: This version should NOT be suid root. (This uses ssh to do the transfer |
7 | * and ssh has the necessary privileges.) | |
