Using the Secure Shell Protocol (SSH) | 81 |
Generating the SSH The SSH Key Generate Page generates both the DSA and RSA key pairs. Key No keys are generated in the switch’s factory default configuration. You
must use this web page to create a public host key.
Gererating a SSH key can take up to 15 minutes, during which time the user interface to the switch may not respond.
To generate DSA and RSA keys:
1Click Security > SSH > Generate. The SSH Key Generate Page opens:
Figure 41 SSH Key Generate Page
The SSH Key Generate Page contains a prompt message to enter a seed to randomize the key generation process:
2Enter any random string, preferably eight characters or more.
3Click 
. The switch begins generating the public host key. This process takes several minutes to complete. After the key is generated, it is stored in flash memory.
The SSH server on the switch uses this host key to negotiate a session key and encryption method with the client trying to connect to it.
Some SSH client programs automatically add the public key to the known hosts file as part of the configuration process. Otherwise, you must manually create a known hosts file and place the host public key in it.
