Postgresql problem

[charsta]

Hello all,

I'm new to pentest world and I am trying to figure out/learn how metasploit and armitage work on Kali.
I made a search about the steps to run Armitage and i found this: source (http://blog.strategiccyber.com/2013/02/06/getting-started-with-armitage-and-the-metasploit-framework-2013/)
In order to run armitage i need to run this first:
service postgresql start

But I can't make it work. Every time I run the above command I am getting an error saying that it failed to run:


[....] Starting PostgreSQL 9.1 database server: main[....] The PostgreSQL server failed to start. Please check the log output:
2013-05-28 23:41:47 BST LOG: could not bind IPv6 socket: Address already in use

2013-05-28 23:41:47 BST FAIL could not create any TCP/IP sockets ... failed!


Can someone explain me if I do something wrong or how can I fix this?

Thank you for your time.

Looks like postgresql is already started or you have another process using the port 5432. please give us the output of this following command:


netstat -tulpn | grep 5432

Turned out that this was caused by nexpose. After I uninstalled nexpose, postgresql run correctly! Thank you!
