Initial version of Blue Box IP authentication script for use as 2-factor solution
with SSH and yubiauthd
Playing nice with syslog filehandles
Renaming bbg-ip-check, and also updating IPv6 subnet function to handle quads with leading zeros correctly.
Better sanity checking of yubicode; Logging of all bad auth attempts; Checking return value of system() call so that abnormal exits to that call itself (not just the retval of yubiauth) qualify as a failure, as they should.
