-Database troubleshooting
-------------------------
-If the database is not connecting automatically, first make sure it is running:
-* Linux:`$ netstat -lnt | grep 7337` where 7337 is whatever port you told it to listen on during installation
-* Windows: look for a postgres.exe process in task manager.
-
-If postgres is not running, try starting it manually:
-* Linux:`$ sudo /etc/init.d/metasploit start` or if you didn't choose to install as a service: `$ sudo /opt/metasploit*/ctlscript.sh start`
-* Windows: Start -> Metasploit -> Services -> Start Services
-
-Once postgres is running and listening, go back to msfconsole:
-
-```
-msf > db_connect
-```
