How to Connect Securely to Cluster Consoles

Perform this procedure to establish secure shell connections to the consoles of the cluster nodes.

Before You Begin

Configure the clusters file, the serialports file, and the nsswitch.conf file if you are using a terminal concentrator. The files can be either /etc files or NIS or NIS+ databases.

In the serialports file, assign the port number to use for secure connection to each console-access device. The default port number for secure shell connection is 22.

See the clusters(4) and serialports(4) man pages for more information.

1. Become superuser on the administrative console.

2. Start the cconsole utility in secure mode.

   # cconsole -s [-l username] [-p ssh-port]

   -s

   Enables secure shell connection.

   -l username

   Specifies the user name for the remote connections. If the -l option is not specified, the user name that launched the cconsole utility is used.

   -p ssh-port

   Specifies the secure shell port number to use. If the -p option is not specified, the default port number 22 is used for the secure connections.
