NAME
ucspi-proxy - Copy data between a UCSPI client and serverSYNOPSIS
ucspi-proxy [ -v ] [ -t TIMEOUT ] [ HOST PORT ]DESCRIPTION
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.
OPTIONS
- -l MAXLINE
- The maximum length of lines (from either server or client) to copy to the log. Defaults to 64.
- -s ADDRESS
- Set the local source address for outbound connections. Use auto to take the address from the original socket address.
- -t TIMEOUT
- When making an connection, ucspi-proxy will wait a maximum of TIMEOUT seconds before giving up. Defaults to 30.
- -T TIMEOUT
- ucspi-proxy will exit after TIMEOUT seconds of inactivity on both sockets. Defaults to no timeout.
- -v
- Print messages about errors and byte counts. Without this option, ucspi-proxy is silent.
RETURN VALUE
Exits 0 if a normal end of file was reached on one of the sockets. Otherwise it exits 1.SEE ALSO
