Please run the SlackBuild script as root user. You will need "postgres" user and group before running the installer, if you haven't installed SlackBuilds PostgreSQL you should run these commands to be compatible: # groupadd -g 209 postgres # useradd -u 209 -g 209 -d /var/lib/pgsql postgres otherwise, you're already setup. Also, remember to add something like: # Start Metasploit Framework PostgreSQL if [ -x /etc/rc.d/rc.metasploit ]; then /etc/rc.d/rc.metasploit start fi to /etc/rc.d/rc.local to start the shipped PostgreSQL daemon and something like: # Stop Metasploit Framework PostgreSQL if [ -x /etc/rc.d/rc.metasploit ]; then /etc/rc.d/rc.metasploit stop fi to /etc/rc.d/rc.local_shutdown to stop the service. Please note that rc.metasploit only starts the framework's PostgreSQL database. In latest releases, Rapid7 introduced a product key mechanism to the framework. In order to run pro applications included, the user requires a valid product key released by Rapid7; those are disabled for running by default. Upgrading the whole binary distribution is also not possible without the key, altough msf3 core directory (which contains the exploits' code as well as all the other modules) will be upgraded by "msfupdate" as expected. Product key is therefore not required in any way to use the full capabilities of the framework, as well as upgrading correctly the core directory through git. In case you want to obtain a valid product key, it is possible to register the Metasploit Community Edition for free. Default database server listening port is 7175, if you want to use another port, just export the PG_PORT variable when running the SlackBuild, like this: # PG_PORT="5454" ./metasploit.SalckBuild An optional cron script to keep the framework up to date is distributed inside the /usr/doc/metasploit-${VERSION} directory and it's called "msfupdate.sh", there also is a logrotate config file called "msfupdate.logrotate" which can be useful.
