a673e210 |
5 | * This is mainly based on ssh-1.2.26/scp.c by Timo Rinne & Tatu Ylonen. |
6 | * They, in turn, used stuff from BSD rcp. |
7 | * |
8 | * (SGT, 2001-09-10: Joris van Rantwijk assures me that although |
9 | * this file as originally submitted was inspired by, and |
10 | * _structurally_ based on, ssh-1.2.26's scp.c, there wasn't any |
11 | * actual code duplicated, so the above comment shouldn't give rise |
12 | * to licensing issues.) |
