sshUtil genkey prompts for user input on the following parameters: passphrase Accepts a string of arbitrary length. This operand is optional, but creating a pass phrase is strongly recommended. A strong pass phrase is 10-30 characters long, fairly complex and difficult to guess. and contains a mix of upper and lowercase letters, numbers, and nonalphanumeric characters. There is no way to recover a lost pass phrase. If the pass phrase is lost, a new key must be generated and copied to the corresponding public key to other machines. exportpubkey Exports the public key from the switch to a specified remote host to support outgoing connections from the switch to a remote host. This option can only be performed by a configured user. The successfully exported public key must be appended to the authorized_keys file on the remote host. Use the cat ~/.ssh/outgoing.pub >> ~/.ssh/authorized_keys command to append the file. exportpubkey prompts for IP Address, remote directory, login name and password. Refer to importpubkey for a description of these parameters. delprivkey Deletes the private key for outgoing connection from the switch. This option can only be performed by a configured user. Deletion of a configured user's private keys effectively blocks outgoing connections initiated by this user that rely on public key authentication with a remote host. delknownhost [-all] Deletes the known host name or IP address from the file .ssh/known_hosts. This option can only be performed by the authorized user. On deletion of a known host name or IP address from the .ssh/known_hosts file, the next SSH connection prompts the user to accept a new public key. -all Deletes all the known host names or IP addresses from the file. genhostkey [-rsa | -dsa | -ecdsa] Generates a host key and installs it on the switch. showhostkey Displays the host keys installed on the switch. deletehostkey [-rsa | -dsa | -ecdsa] Deletes the host keys installed on the switch. help Displays the command usage. Examples To configure a user for public key authentication: switch:admin> sshutil allowuser username Allowed user has been successfully changed to username. 1046 Brocade Fabric OS Command Reference 53-1004112-02
