Configuring Secure Shell (SSH) Configuring the Switch for SSH Operation (The generated public key on the switch is always 896 bits.) With a direct serial connection from a management station to the switch: 1. Use a terminal application such as HyperTerminal to display the switch's public key with the show crypto host-public-key command (figure 6-5). 2. Bring up the SSH client's "known host" file in a text editor such as Notepad as straight ASCII text, and copy the switch's public key into the file. 3. Ensure that there are no changes or breaks in the text string. (A public key must be an unbroken ASCII string. Line breaks are not allowed Changes in the line breaks will corrupt the Key.) For example, if you are using Windows® Notepad, ensure that Word Wrap (in the Edit menu) is disabled, and that the key text appears on a single line. Figure 6-7. Example of a Correctly Formatted Public Key 4. Add any data required by your SSH client application.
