How to install secnet on a Fink-equipped OS X system: - Install GMP: fink install gmp - Download and install ADNS: ./configure --disable-dynamic make sudo make install - Build secnet: ./configure CPPFLAGS=-I/sw/include LDFLAGS=-L/sw/lib make sudo make install - Install tuntap for OSX from http://tuntaposx.sourceforge.net/ - Create /etc/secnet/{key,secnet.conf,sites.conf} as usual - If you don't want secnet 'always on', edit uk.org.greenend.secnet.plist and remove *both* these two lines: RunAtLoad - Create the 'secnet' user and install the job configuration: ./setup.mac. To start secnet: sudo launchctl start uk.org.greenend.secnet To stop secnet: sudo launchctl stop uk.org.greenend.secnet To uninstall: sudo launchctl unload /Library/LaunchDaemons/uk.org.greenend.secnet.plist sudo rm -f /Library/LaunchDaemons/uk.org.greenend.secnet.plist If you need to enable IP forwarding: sudo sysctl -w net.inet.ip.forwarding=1 (Note that on a Mac, you need to enable IP forwarding if you want to route to addresses on one interface via another; i.e. if you expect to be able to reach an address on en0 with a packet delivered through tun0, IP forwarding must be turned on.)
