Subsystems

Subsystems can be defined in the sshd2_config file using the following syntax.

subsystem-<name>      argument

The argument is the command which will be executed when the subsystem is requested.

$ ssh2 user@remote -s <name>

The argument can be a list of commands separated with a semicolon (;), or it can, for example, refer to a script.

One example of a subsystem is sftp.

subsystem-sftp      /usr/lpp/ssh2/sftp-server

The sftp subsystem also has an internal alternative. This should be used for example when the user is chrooted and does not have access to the sftp-server binary.

subsystem-sftp      internal://sftp-server
