ucspi-proxy - Copy data between a UCSPI client and server
ucspi-proxy [ -v ] [ -t TIMEOUT ] [ HOST PORT ]
This program is a simple loop copying data from a UCSPI server (file
descriptor 0) to a client, and from a client to a server (FD 1). If
either socket closes, ucspi-proxy exits. The other ucspi-proxy-*
programs are based on this simple loop and have similar usage.
If HOST and PORT are given on the command line, ucspi-proxy will make a
TCP connection with the given parameters. If neither are present,
ucspi-proxy will use file descriptor 6 for the client socket, as
provided by UCSPI client programs.
When making an connection, ucspi-proxy will wait a maximum of
TIMEOUT seconds before giving up. Defaults to 30.
-v Print messages about errors and byte counts. Without this
option, ucspi-proxy is silent.
Exits 0 if a normal end of file was reached on one of the sockets.
Otherwise it exits 1.
