bcbf86ec | 2 | * scp - secure remote copy. This is basically patched BSD rcp which |
3 | * uses ssh to do the data transfer (instead of using rcmd). | |
6ae2364d | 4 | * |
bcbf86ec | 5 | * NOTE: This version should NOT be suid root. (This uses ssh to |
6 | * do the transfer and ssh has the necessary privileges.) | |

bcbf86ec | 10 | * As far as I am concerned, the code I have written for this software |
11 | * can be used freely for any purpose. Any derived versions of this | |
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 | |
14 | * called by a name other than "ssh" or "Secure Shell". | |
