NAME¶
ucspi-proxy - Copy data between a UCSPI client and server
SYNOPSIS¶
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¶
- -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.
RETURN VALUE¶
Exits 0 if a normal end of file was reached on one of the sockets. Otherwise it
exits 1.
