Now I'm confused...
[jsage () sparky /storage/virii] $ nc -h
GNU netcat 0.7.1, a rewrite of the famous networking tool.
connect to somewhere: nc [options] hostname port [port] ...
listen for inbound: nc -l -p port [options] [hostname] [port] ...
tunnel to somewhere: nc -L hostname:port -p port [options]
Mandatory arguments to long options are mandatory for short options too.
-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
/* snip */
Does persistent listener == tunnel?
hmm.. my netcat is different and i compiled from Hobbit's sources..
-------------------- snip -------------------
C:\Documents and Settings\Administrator>nc -h
connect to somewhere: nc [-options] hostname port[s] [ports] ...
listen for inbound: nc -l -p port [options] [hostname] [port]
-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
-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]
port numbers can be individual or ranges: m-n [inclusive]
------------------- snip --------------------
note: " -L listen harder, re-listen on socket close"
mabey confusion rules the day?
or your "GNU netcat 0.7.1, a rewrite of the famous networking tool."
netcat really sucks
Full-Disclosure - We believe in it.
