Configuring SSH
This section describes how to configure the switch as an SSH server. For
a description of all the steps required to configure an SSH server, see
”General Steps for Configuring SSH” on page 611.
Before you begin this procedure, you need to configure a host and
server keys for SSH. See Chapter 26, ”Encryption Keys” on page 547. The
minimum bit size of the server key is 512 bits. The recommended bit size
for a server key is 768 bits. The recommended size for the host key is
1024 bits. In addition, the bit size of the host and server keys must differ
by 128 bits.
While you are configuring the SSH feature, you must disable the SSH
server. When you have completed your configuration changes, enable
the SSH server to permit SSH client connections.
Note
Allied Telesyn recommends disabling the Telnet server before you
enable SSH. Otherwise, the security functions provided by SSH are
lost. See ”Enabling or Disabling the Telnet Server” on page 68.
To configure the SSH protocol, perform the following procedure:
1. From the Main Menu, type 8 to select Security Configuration.
The Security Configuration menu is shown in Figure 175 on page
559.
2. From the Security Configuration menu, type 4 to select Secure Shell
(SSH).
The Secure Shell (SSH) menu is shown in Figure 192.
