Pro OpenSSH

SSH, acronym for Secure Socket Shell, is the de facto standard among users and administrators wishing to establish secure communication between disparate networks. Pro OpenSSH, authored by two Fortune 100 system administrators, provides readers with a highly practical reference for configuring and deploying OpenSSH in their own environment. OpenSSH installation and configuration, key management, secure logging, client/server architectures, and digital certificates are just some of the topics covered in this book. Readers are also treated to complete deployment scenarios that come up almost daily in enterprise environments, large or small.
