.
2. The server key is re-generated when the managed switch is reset to its factory default setting or a received
key is non-existent.
SSH version 2 has the following features:
1. Client programs that use SSH can perform remote logins, remote command execution, and secure file
copying across a network
.
2. Several selectable encryption algorithms and authentication mechanisms are supported by the SSH
.
3. An SSH agent can cache keys for easy access in later session.
4. Encryption ciphers, i.e. Triple Data Encryption Standard (3DES) and Advanced Encryption Standard (AES).
5. The use of sound cryptographic Message Authentication Code (MAC) algorithms for integrity checking.
Examples of secure hash (functions) algorithms which are MAC algorithms in SSH version 2 are the
Message Digest algorithm5 (MD5) and Secure Hash Algorithm 1 (SHA-1).
6. Support for public key certificates.
2.3.12 Telnet
This subsection allows the users to set the Telnet option for the managed switch. The command line interface (CLI)
configuration using Telnet (as described in Chapter 4) or SSH (previous section) are the same except that the SSH
encrypts the communication data. For the Telnet administration, the managed switch only provides the enable or
disable function selectable in this webpage. The default setting for Telnet is enabled. Clicking on the
Update
button
when you change the option to update it on the managed switch. Figure 2.51 shows the Telnet setting webpage.
Note that the users are recommended to use SSH instead of Telnet for higher security protection of your managed
switch.
