SSH Server and SCP Commands
FTOS supports secure shell (SSH) protocol versions 1.5 and 2.0. SSH is a protocol for secure remote
login over an insecure network. SSH sessions are encrypted and use authentication. The SSH and SCP
commands are:
• crypto key generate
• debug ip ssh
• ip scp topdir
• ip ssh authentication-retries
• ip ssh connection-rate-limit
• ip ssh hostbased-authentication
• ip ssh key-size
• ip ssh password-authentication
• ip ssh pub-key-file
• ip ssh rhostsfile
• ip ssh rsa-authentication (Config)
• ip ssh rsa-authentication (EXEC)
• ip ssh server
• show crypto
• show ip ssh
• show ip ssh client-pub-keys
• show ip ssh rsa-authentication
• ssh
