I can't get metasploit to connect to the DB. I run all the things that previous threads have said to do, such as start postgresql and metasploit and adding it to the startup, but when I run metasploit I get password auth failed, password failed for user msf3, and to make that better, I run db_status and it says postgresql is not connected. I'm not understanding this. I've reinstalled both metasploit and postgresql several times. I'm running the gnome 64bit of kali. so my questions are basically, how do I remove the password failed for msf3 and how can I connect the postgresql to metasploit since obviously nothing is working
