Compiling OpenSSH on Ubuntu Server

Installing the OpenSSH client and server on Ubuntu is as easy as typing "sudo apt-get install openssh" at a terminal prompt. However, this will install Portable OpenSSH version 4.3p2[-8ubuntu1]. Unfortunately for users, this version of Portable OpenSSH does not include the "Match" functionality added to the SSH server in version 4.4p1, that "allows some configuration options to be selectively overridden if specific criteria (based on user, group, hostname and/or address) are met."
