Compile Tripwire by running the following commands: patch -Np1 -i ../tripwire-&tripwire-version;-gcc3-build-fixes.patch && make -C src release && cp install/install.{sh,cfg} . The default configuration is to use a local MTA. If you don't have a MTA installed and have no wish to install one, modify the install.cfg to use an SMTP server instead. Install Tripwire by running the following commands: ./install.sh && cp /etc/tripwire/tw.cfg /usr/sbin && cp policy/*.txt /usr/share/doc/tripwire
