F-Secure SSH Server (SSH, The Secure Shell: The Definitive Guide)

4.2. F-Secure SSH Server

F-Secure Corporation, formerly DataFellows, Ltd., a Finnish software company, produces commercial implementations of SSH derived from those of SSH Communications Security. F-Secure's server product line, F-Secure SSH Server, runs on Unix, and SSH-1 and SSH-2 servers are available as separate products. They are repackagings of SSH1 and SSH2 with commercial licenses and a few added features:

A manual covering F-Secure SSH products for all platforms (Unix, Windows, Macintosh)

Additional encryption algorithms in the SSH-2 product, such as RSA and IDEA. (see the F-Secure manual for the current list)

An additional SSH client, edd ( Encryption Data Dump), a Unix filter that applies SSH encryption or decryption to standard input, writing the results to standard output
A few additional options in SSH1 (see Appendix B, "SSH Quick Reference")

4.2.1. Obtaining and Installing

F-Secure SSH Server is available from http://www.f-secure.com/. In addition to their commercial SSH products, which may be purchased and downloaded from the web site, free "evaluation versions" are available.

Except for the few additional features listed in the previous section, installation, configuration, and operation of F-Secure Unix SSH is almost identical to that of the SCS versions. SSH2 has moved ahead with new features not present in its F-Secure counterpart, however, so check the F-Secure documentation to see if particular features are available.
