looks at OpenSSH and bash. "As a system
administrator, I have used OpenSSH's piping abilities more times than I can
remember. The typical ssh call gets me access to systems for
administration with a proven identity, but ssh is capable of so
much more. In combination with bash's subshell invocation, OpenSSH can
distribute the heavy work, reduce trace interference on a system under
test, and make other "impossible" tasks possible.
