Commands

Refer to the man pages for scp for a description and any command options.

sftp

Use sftp for a secure file transfer transaction using ssh, between two servers. This process is similar to ftp except that it is encrypted for security.

Refer to the man pages for sftp for a description and any command options.

ssh

The SCS systems use ssh to establish secure connections over your network. The configuration file for ssh is /etc/ssh/sshd_config.

You use ssh to establish a secure connection between two hosts, or to transfer files or data between the systems. With the SCS, the Secure Console Server is a client device, and will be connected to an ssh host elsewhere. The security keys for ssh may need to be generated using ssh-keygen, depending on your application of ssh.

Refer to the man pages for ssh for a description and any command options.

ssh-keygen

Use ssh-keygento create keys for users so passwords don’t have to be used for ssh login. You can generate the security keys for your client system (in this case, the SCS is the client) to interact with an ssh host elsewhere. After the keys have been gen- erated, the user can establish a secure shell connection using ssh over a network.

Refer to the man pages for ssh for a description and any command options.

stty

Use stty to change the configuration for each Port. The system provides a default configuration for the system Ports (ttyB1 through ttyB48), and for the Con- sole Port (ttyS0).

Note

Port changes made using stty are temporary (not written to mem- ory). In order to keep any changes, you must edit the configuration file

in /etc/rc.d/rc.serial .

The Ports are identified as /dev/ttyB1 through /dev/ttyB48 for ports 1 through 48, respectively, and /dev/ttyS0 for the Console Port.
