bcbf86ec | 3 | * scp - secure remote copy. This is basically patched BSD rcp which |
4 | * uses ssh to do the data transfer (instead of using rcmd). | |
6ae2364d | 5 | * |
bcbf86ec | 6 | * NOTE: This version should NOT be suid root. (This uses ssh to |
7 | * do the transfer and ssh has the necessary privileges.) | |

15 | * called by a name other than "ssh" or "Secure Shell". | |
