[v1.12 NT http://eternallybored.org/misc/netcat/] Thanks a ton.

connect to somewhere: nc [-options] hostname port[s] [ports] ... listen for inbound: nc -l -p port [options] [hostname] [port] options: -d detach from console, background mode

    -e prog         inbound program to exec [dangerous!!]
    -g gateway      source-routing hop point[s], up to 8
    -G num          source-routing pointer: 4, 8, 12, ...
    -h              this cruft
    -i secs         delay interval for lines sent, ports scanned
    -l              listen mode, for inbound connects
    -L              listen harder, re-listen on socket close
    -n              numeric-only IP addresses, no DNS
    -o file         hex dump of traffic
    -p port         local port number
    -r              randomize local and remote ports
    -s addr         local source address
    -t              answer TELNET negotiation
    -c              send CRLF instead of just LF
    -u              UDP mode
    -v              verbose [use twice to be more verbose]
    -w secs         timeout for connects and final net reads
    -z              zero-I/O mode [used for scanning]
