sorry, it's GNU Netcat (known as nc), it doesn't have '-U' option. What we used in autotest is OpenBSD Netcat, it has '-U' option. http://www.openbsd.org/cgi-bin/cvsweb/src/usr.bin/nc/ man page: http://nixdoc.net/man-pages/openbsd/man1/nc.1.html it's installed in my fedora 16 by default. # rpm -ql nc-1.101-3.fc16.x86_64 /usr/bin/nc /usr/share/man/man1/nc.1.gz > you can get code from SF and compile by yourself. > > > > > > > Thanks > > > I make a mistake, take netstat as netcast > > > after I build one netcat, I don't see "nc" command and netcat show me > there is no "-U" support but "-u" > GNU netcat 0.7.1, a rewrite of the famous networking tool. > Basic usages: > connect to somewhere: ./netcat [options] hostname port [port] ... > listen for inbound: ./netcat -l -p port [options] [hostname] [port] > ... > tunnel to somewhere: ./netcat -L hostname:port -p port [options] > > > Mandatory arguments to long options are mandatory for short options > too. > Options: > -c, --close close connection on EOF from stdin > -e, --exec=PROGRAM program to exec after connect > -g, --gateway=LIST source-routing hop point[s], up to 8 > -G, --pointer=NUM source-routing pointer: 4, 8, 12, ... > -h, --help display this help and exit > -i, --interval=SECS delay interval for lines sent, ports scanned > -l, --listen listen mode, for inbound connects > -L, --tunnel=ADDRESS:PORT forward local port to remote address > -n, --dont-resolve numeric-only IP addresses, no DNS > -o, --output=FILE output hexdump traffic to FILE (implies -x) > -p, --local-port=NUM local port number > -r, --randomize randomize local and remote ports > -s, --source=ADDRESS local source address (ip or hostname) > -t, --tcp TCP mode (default) > -T, --telnet answer using TELNET negotiation > -u, --udp UDP mode > -v, --verbose verbose (use twice to be more verbose) > -V, --version output version information and exit > -x, --hexdump hexdump incoming and outgoing traffic > -w, --wait=SECS timeout for connects and final net reads > -z, --zero zero-I/O mode (used for scanning) > > > Remote port number can also be specified as range.
