Nmap: Network Exploration and Security Auditing Cookbook - Second Edition

Configuring authentication options

Ncrack would not be a good network login cracker without options to tune the authentication process. Ncrack users may use their own username and password lists with the options -U and -P correspondingly if the included lists (inside the directory /lists) are not adequate:

$ ncrack -U <user list file> -P <password list file> <[service-name]>://<target>:<[port-number]>  

Otherwise, we might have a specific username or password we would like to test with the options --user and --pass:

$ ncrack --user <username> <[service-name]>://<target>:<[port-number]>$ ncrack --pass <password> <[service-name]>://<target>:<[port-number]>
