In an age of more or less constant attacks against our
networks and computers, secure communications are more
important than ever. The Secure Shell (SSH) protocols
provide secure drop-in replacements for traditional
communication tools such as telnet and ftp. In addition to
describing the SSH protocols, how they work, and how they
can be used to perform the familiar telnet and ftp
functions, this chapter explores using SSH to link any two
applications securely, and even how to set up an ad hoc VPN
that links two networks.
Read Chapter 7, SSH from VPNs Illustrated: Tunnels, VPNs, and IPsec written by Jon C. Snader and published by Addison-Wesley Professional.
