Configuring Protocols Configuring outgoing SSH authentication After the allowed-user is configured, the remaining setup steps must be completed by the allowed-user. Use the following procedure to configure outgoing SSH authentication. 1. Log in to the switch as the default admin. 2. Change the allowed-user's permissions to admin, if applicable. switch:admin> userconfig --change username -r admin The username variable is the name of the user who can perform SSH public key authentication, and who can import, export, and delete keys. 3. Set up the allowed-user by typing the following command: switch:admin> sshutil allowuser username The username variable is the name of the user who can perform SSH public key authentication, and who can import, export, and delete keys. 4. Generate a key pair for switch-to-host (outgoing) authentication by logging in to the switch as the allowed-user and entering the sshUtil genkey command. You may enter a passphrase for additional security. Example of generating a key pair on the switch switch:alloweduser> sshutil genkey Enter passphrase (empty for no passphrase): Enter same passphrase again: Key pair generated successfully. 5. Export the public key to the host by logging in to the switch as the allowed-user and entering the sshUtil exportpubkey command to export the key. Example of exporting a public key from the switch switch:alloweduser> sshutil exportpubkey Enter IP address:192.168.38.244 Enter remote directory:~auser/.ssh Enter login name:auser Password: public key out_going.pub is exported successfully. 6. Append the public key to a remote host by logging in to the remote host, locating the directory where authorized keys are stored, and appending the public key to the file. You may need to refer to the host's documentation to locate where the authorized keys are stored. 7. Test the setup by using a command that uses SCP and authentication, such as firmwareDownload or configUpload. Deleting public keys on the switch Use the following procedure to delete public keys from the switch. 1. Connect to the switch and log in using an account with admin permissions. 2. Use the sshUtil delpubkeys command to delete public keys. Brocade Fabric OS Administration Guide, 8.0.1 53-1004111-02 189
