Installing a Single Port

Thanks to this thread I learned how to install a single port that doesn't appear in the ports tree. For example, GNU netcat just appeared at Freshports.org on 12 Jan. I wanted to install this one port to a FreeBSD 4.9 REL box that hasn't ever updated its port tree, as shown here:

moog# ls -al /usr/ports/INDEX*
-rw-r--r--  1 root  wheel  4003057 Oct  2 16:55 /usr/ports/INDEX
-rw-r--r--  1 root  wheel  4036779 Aug 15 21:56 /usr/ports/INDEX-5

I visited /ports/net/gnetcat and chose the download this directory in tarball option. This copied gnetcat.tar.gz to my system, and I moved it to /usr/local/ports/net. Next I extracted it and ran make and make install:

moog# tar -xzvf gnetcat.tar.gz 
gnetcat/
gnetcat/Makefile
gnetcat/distinfo
gnetcat/pkg-descr
gnetcat/pkg-plist
gnetcat/files/
gnetcat/files/patch-src-udphelper.c
moog# cd gnetcat
moog# make && make install
>> netcat-0.7.1.tar.bz2 doesn't seem to exist in /usr/ports/distfiles/.
>> Attempting to fetch from http://us.dl.sourceforge.net/netcat/.
Receiving netcat-0.7.1.tar.bz2 (325687 bytes): 45%
...edited...

When done I did a "rehash" and found gnetcat on my system:

moog# rehash
moog# which gnetcat
/usr/local/bin/gnetcat
moog# gnetcat -h
GNU netcat 0.7.1, a rewrite of the famous networking tool.
Basic usages:
connect to somewhere:  gnetcat [options] hostname port [port] ...
listen for inbound:    gnetcat -l -p port [options] [hostname] [port] ...
tunnel to somewhere:   gnetcat -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.  Example: '1-1024'

I plan to test gnetcat to see how it compares to the original nc.
