SPA requires only a single encrypted packet in order to communicate various pieces of information including desired access through a Netfilter policy and/or complete commands to execute on the target system. By using Netfilter to maintain a 'default drop' stance, the main application of this program is to protect services such as OpenSSH with an additional layer of security in order to make the exploitation of vulnerabilities (both 0-day and unpatched code) much more difficult. The authorization server passively monitors authorization packets via libcap and hence there is no 'server' to which to connect in the traditional sense. Access to a protected service is only granted after a valid encrypted and non-replayed packet is monitored. This port installs the client side script that you run to gain access to a Linux box. master_sites http://www.cipherdyne.org/fwknop/download/ checksums md5 c64e78e408402fd00026affe448ee620 sha1 8b4621fa7870ae3f1075de99d2280f004bf79cd3 use_bzip2 yes depends_lib port:p5-crypt-cbc port:p5-crypt-rijndael port:p5-net-ipv4addr port:p5-net-ping-external port:p5-term-readkey port:p5-unix-syslog configure {} build {} destroot { system "cd ${worksrcpath} && ${prefix}/bin/perl -w -p -i -e 's:^#!/usr/bin/perl -w$:#!${prefix}/bin/perl -w:' fwknop" system "cd ${worksrcpath} && ${prefix}/bin/perl -w -p -i -e 's:^use lib ./usr/lib/fwknop.;::' fwknop" xinstall -m 755 ${worksrcpath}/fwknop ${destroot}${prefix}/bin xinstall -m 644 ${worksrcpath}/fwknop.8 ${destroot}${prefix}/share/man/man8 } If you haven't already installed Darwin Ports, you can find easy instructions for doing so at the main Darwin Ports page.
