reset-modem
Use this command to reset the internal modem. (SCSxx20 only)
scp
Use scp to perform a secure copy , using SSH, between two hosts. The file copy
is encrypted and is therefore secure.
Refer to the man pages for scp for a description and command options.
sftp
Use sftp to perform a secure file transfer transaction, using SSH, between two
servers. It is similar to ftp except that it is encrypted for security.
Refer to the man pages for sftp for a description and command options.
ssh
Use ssh to open up a secure shell connection between two hosts to transfer files
or data between the systems. In this case, the SCS is a client device and is
connected to an SSH host elsewhere. You may need to generate the security
keys for SSH using
ssh-keygen , depending on your application of SSH.
Refer to the man pages for SSH for a description and command options.
ssh-keygen
Use ssh-keygen to create the security keys for your client system to interact with
an SSH host elsewhere. After the keys have been generated, the user can
establish a secure shell connection using SSH over a network.
See Advanced Sysadmin Commands later in this chapter for an ssh-keygen
tutorial. Refer to the man pages for SSH for a description and command options.
