Missing -C (CRLF as EOL) option in Netcat #809

The version of Netcat included with Photon does not contain the -C option to use CRLF for EOL. This is a particularly helpful option while troubleshooting and many forks of Netcat, such as Debian's have added this functionality. Red Hat has opted to replace Netcat with Nmap's Ncat, which also has this option and is in active development. Either of these choices would expand the current troubleshooting options.

What netcat version and from what distribution are you referencing to? We might need to patch netcat in order to support it.

Doing some more research, it appears that Debian (and derivatives) used the actively developed netcat-openbsd versus netcat-traditional (written by Hobbit). netcat-openbsd is a rewrite the includes support for IPv6, proxies, Unix sockets, and has the previously mentioned -C option. In Debian Jessie and Stretch, it is currently at version 1.10-41.
