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.
-l MAXLINE
The maximum length of lines (from either server or client) to copy to the log. Defaults to 64.
-t TIMEOUT
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.
