SSH is an inexpensive, easily configured improvement for secure
administration of *NIX servers over the Internet. In this ISP-Planet
"how to", we explain how to set up an OpenSSH server and how to use
SSH port forwarding to create a low-cost, limited functionality
circuit-level VPN.

Many of today's VPNs exist without the support of a public key
infrastructure. Rudimentary preshared keys work fine on a small scale,
but become unwieldy in larger VPNs, especially large remote access
VPNs with hundreds or thousands of clients. In this column, Lisa
Phifer provides an overview of PKI and how it impacts VPN deployment.

Lisa describes the simple steps required to configure and monitor
Envoy to create a distributed Internet presence.
