Comments for netcat
IPv6 Port
I had a problem compiling the IPv6 version on FreeBSD 5.0. Changed the following to make it work:
first_port = strtoul (argv[optind], &tail, 0);
if (first_port > USHRT_MAX || *tail || first_port == 0)
bail ("invalid port %s", argv[optind]);
last_port = strtoul (cp, &tail, 0);
if (last_port > USHRT_MAX || *tail || last_port == 0)
bail ("invalid port %s", cp);
Change USHRT_MAX to 65535, then compile. Works like a charm.

Check the comments a little down the page titled 'compile for linux.' The error you mention goes away by adding 'include resolv.h' to netcat.c
Compile error
When I compile netcat on Linux it gives me this errors:
/tmp/cccUSCm5.o: In function `main':
/tmp/cccUSCm5.o(.text+0x1b1a): undefined reference to `res_init'
collect2: ld returned 1 exit status
A patch for Netcat
We made a patch for Netcat that provides a TCP connection between Client and Server, and lets the Client the possibility to specify the file which it is interested in.

and do not forget to create a directory, in case you don't want to overwrite any Makefile's or README's you might have on the directory you'll extract the contents of nc*.tgz :-)
Compil for Linux
On redhat 7.2 :
include "resolv.h"

Or include limits.h. Silly me.
