Secure Shell and Secure Copy

Secure Shell (SSH) and Secure Copy (SCP) use secure tunnels to encrypt and secure messages between a remote administrator and the switch. Telnet does not provide this level of security. The Telnet method of managing a GbE Switch Module does not provide a secure connection.

SSH is a protocol that enables remote administrators to log securely into the GbE Switch Mod- ule over a network to execute management commands.

SCP is typically used to copy files securely from one machine to another. SCP uses SSH for encryption of data on the network. On a GbE Switch Module, SCP is used to download and upload the switch configuration via secure channels.

The benefits of using SSH and SCP are listed below:

„Authentication of remote administrators

„Identifying the administrator using Name/Password

„Authorization of remote administrators

„Determining the permitted actions and customizing service for individual administrators

„Encryption of management messages

„Encrypting messages between the remote administrator and switch

„Secure copy support

The Alteon OS implementation of SSH supports both versions 1.5 and 2.0. and supports SSH clients version 1.5 - 2.x. The following SSH clients have been tested

„SSH 1.2.23 and SSH 1.2.27 for Linux (freeware)

„SecureCRT 3.0.2 and SecureCRT 3.0.3 for Windows NT (Van Dyke Technologies, Inc.)

„F-Secure SSH 1.1 for Windows (Data Fellows)

„Putty SSH

„Cygwin OpenSSH

„Mac X OpenSSH

„Solaris 8 OpenSSH

„AxeSSH SSHPro

„SSH Communications Vandyke SSH A

„F-Secure
