free legit copy of a newer version, I'll likely be sticking with that

**NB: You need a recent gcc compiler**. On Solaris 10, the gcc that ships with
it- 3.4.3 produces buggy code in encryption routines and you will expericence crashes.
Try with [CSW gcc 5.5.0](https://www.opencsw.org/packages/CSWgcc5core/)

If compilation fails, please file a bug on my [github
page](https://github.com/iagox86/dnscat2/issues)! Please send details
about your system.
