How to access a storage system by using a Remote Shell connection

If the rsh.enable option is set to on, you can access a storage system to perform administrative tasks by using a Remote Shell (RSH) connection.

You can access a storage system by using an RSH connection with a trusted remote host that is listed in the /etc/hosts.equiv file on the root volume.

You can also use a user name and a password to establish an RSH connection from an administration host that is not listed in the /etc/hosts.equiv file. However, passing a password in this manner is a security risk, especially for UNIX clients. On many UNIX clients, this command can be visible to other users on the storage system who run the ps program at the same time the command is executed.

On any client, the password is visible in plain text over the network. Any program that captures network traffic when the password is sent will record the password. To avoid exposing the password when you issue RSH commands, it is best to log in as root on a client listed in the storage system’s /etc/hosts.equiv file.

You can have up to 24 concurrent RSH sessions running on a storage system, and you can have up to 4 concurrent RSH sessions running on each vFiler unit.
