SSH Applications
After the connection phase is completed, SSH allows several application programs to
use the connection. Each application can create a logical channel as described above
and then benefit from the secured connection. In other words, remote login is one of the
services that can use the SSH-CONN protocols; other applications, such as a file transfer
application can use one of the logical channels for this purpose. In the next chapter,
we show how SSH can be used for secure file transfer.
