socat by Gerhard Rieger and contributors - see www.dest-unreach.org Usage: socat [options] <bi-address> <bi-address> options: -V print version and feature information to stdout, and exit -h|-? print a help text describing command line options and addresses -hh like -h, plus a list of all common address option names -hhh like -hh, plus a list of all available address option names -d increase verbosity (use up to 4 times; 2 are recommended) -D analyze file descriptors before loop -ly[facility] log to syslog, using facility (default is daemon) -lf<logfile> log to file -ls log to stderr (default if no other log) -lm[facility] mixed log mode (stderr during initialization, then syslog) -lp<progname> set the program name used for logging -lu use microseconds for logging timestamps -lh add hostname to log messages -v verbose data traffic, text -x verbose data traffic, hexadecimal -b<size_t> set data buffer size (8192) -s sloppy (continue on error) -t<timeout> wait seconds before closing second channel -T<timeout> total inactivity timeout in seconds -u unidirectional mode (left to right) -U unidirectional mode (right to left) -g do not check option groups -L <lockfile> try to obtain lock, or fail -W <lockfile> try to obtain lock, or wait -4 prefer IPv4 if version is not explicitly specified -6 prefer IPv6 if version is not explicitly specified bi-address: pipe[,<opts>]
