Hi,

I’m having issues with task 3. When I follow the solutions exactly, and attempt to exploit a machine from another subnet using Meterpreter, I get this error:

[-] 10.100.40.107:445 - Exploit failed [bad-config]: Rex::BindFailed The address is already in use or unavailable: (0.0.0.0:4444).
[*] Exploit completed, but no session was created.

Even though the solution tells you to set LPORT as 4444.

Anyone else experienced this or knows a fix?

Cheers

Without looking at the lab - I’m guessing if you look at your jobs list you will likely see something else you’ve ran already using Port4444. Kill the job if it’s unnecessary or set a different lport (and ensure your lhost is correct) in the most recent exploit that is failing.
