    A maneira mais facil e aconcelhada e recompilar o openssh logo apos 
modificar o arquivo version.h

ROOT(/root)[8:46]-FreeBSD$ cd /usr/ports/security/openssh && make install

Receiving openssh-3.5.tgz (405198 bytes): 100%

Quando chegar nessa parte da um C-z

Edita o arquivo version.c

----------------------------------------------------------------------
ROOT(/usr/ports/security/openssh)[8:46]-FreeBSD$ vi work/ssh/version.h
/* $OpenBSD: version.h,v 1.35 2002/10/01 13:24:50 markus Exp $ */

#define SSH_VERSION     "OpenSSH_666"
----------------------------------------------------------------------

E logo depois da um fg

Resultado!!! :-)))


NIB(/home/nib)[8:46]-FreeBSD$ telnet 172.22.1.134 22
Trying 172.22.1.134...
