Installing OpenSSH and OpenSSL on AIX 6.1
There are a lot of sites where the process is explained, just google a little bit.
I will describe the one that worked for me:
I am using AIX 6.1 TL4 (upgraded from AIX 5.3 TL6)
I have the AIX Toolbox For Linux Applications of 05.2009
I prefer to have openssh and openssl as native AIX packages. The problem is that .rpm files usually have dependencies with openssl, so I had to install the openssl rpm package as well.
First I downloaded both openssl 0.9.8.1103 (from IBM) and openssh 5.2p1 (from Sourceforge):
I installed it:
mkdir openssh_5.2p1_aix61 && cd openssh_5.2p1_aix61 && uncompress -c < ../openssh_5.2p1_aix61.tar.Z |tar -xvf - && installp -acXYgd . openssh
mkdir openssl.0.9.8.1103 && cd openssl.0.9.8.1103 && uncompress -c < ../openssl.0.9.8.1103.tar.Z |tar -xvf - && installp -acXYgd . openssl
Then I downloaded a compiled version of openssl 0.9.8 from perzl.org (AIX Toolbox For Linux Applications of 05.2009 comes with 0.9.7, but .rpms have dependencies on 0.9.8): http://www.perzl.org/aix/index.php?n=Main.Openssl. And I installed it rpm -i openssl-0.9.8n-1.aix5.1.ppc.rpm.
