Netcat missing -q

[Phishfry]

The netcat manual indicates that netcat -q is a valid option flag
But on FreeBSD 12 &13 I get this:

# nc -q

nc: invalid option -- q
usage: nc [-46DdEFhklNnrStUuvz] [-e policy] [-I length] [-i interval] [-O length]
      [--no-tcpopt] [--sctp]
      [-P proxy_username] [-p source_port] [-s source] [-T ToS]
      [-V rtable] [-w timeout] [-X proxy_protocol]
      [-x proxy_address[:port]] [destination] [port]

What is the deal? Is our base netcat different?

 

[Phishfry]

I see two netcats in ports. Wondering which contains -q flag.

gnetcat-0.7.1_5                GPL'ed re-write of the well known networking tool netcat
netcat-1.10_3                  Simple utility which reads and writes data across network connections

I imagine the gnetcat does what i need.
What is the netcat-1.10_3 version in ports? dev version? Solaris version?

What is the netcat-1.10_3 version in ports?

I believe that's the "original" netcat source. Everything else, including 'our' nc(1) have been (re)implementations.

net/netcat is https://sourceforge.net/projects/nc110/ :

Memorial of original *Hobbit*'s version 1.10 of netcat tool.

By all means install it (/usr/local/bin/netcat via pkg install netcat) if it does something you want and can't get with base's (/usr/bin/nc) nc(1).

 

[Phishfry]

Neither port contains the -q option.
How strange.

Everything else, including 'our' nc(1) have been (re)implementations.

Apparently 'our' nc(1) comes from OpenBSD:

/usr/src/contrib/netcat/FREEBSD-upgrade

nc(1) is very small and most of code are just copied as-is from OpenBSD.  With a
few exceptions:

 * --no-tcpopt: Local feature specific to FreeBSD.
 * -V: We use FIB to map what OpenBSD do for "rdomain"
 * -E, -e: These are mostly self contained IPsec extensions

And theirs

 * Re-written nc(1) for OpenBSD. Original implementation by
 * *Hobbit* <hobbit@avian.org>.

Phishfry, you didn't mention for what purpose you need netcat, but have a look at net/socat, maybe it suits your needs.
