Exec format error. Wrong Architecture

[Jun Zhang]

I'm trying to do a network installation of openssh 2.3.0 for all
my sun servers and workstations (more than 200, all run Solaris 5.6).
Initially, I
installed it on a E4500, and sshd run well locally. Then I ran sshd from

another host, which is a sparc 20, error message came out like,

    Exec format error. Wrong architecture.

Do I have to install ssh on all different machines?
