.Sh DESCRIPTION
|
||
|
|
.Nm
|
||
|
|
communicates with another program over two byte steams and asks the remote
|
||
|
|
program (usually
|
||
|
|
.Xr sfncd 1 )
|
||
|
|
to connect to the specified
|
||
|
|
.Ar host
|
||
|
|
and
|
||
|
|
.Ar port .
|
||
|
|
.Pp
|
||
|
|
It reads bytes from the standard input and transmits them across
|
||
|
|
.Ar transmit-device .
|
||
|
|
It receives bytes from
|
||
|
|
.Ar receive-device
|
||
|
|
and sends them to the standard output.

.Ss Protocol
|
||
|
|
The client transmits in one
|
||
|
|
.Xr sf 1
|
||
|
|
session, which contains two nested
|
||
|
|
.Xr sf 1
|
||
|
|
connections (first host, then port), and then the actual body read from the
|
||
|
|
standard input. The server transmits in one
|
||
|
|
.Xr sf 1
|
||
|
|
session, which begins once the host and port has been received, and it contains
|
||
|
|
the response.
