Scanner SMB Auxiliary Modules
a11y.text Scanner SMB Auxiliary Modulespipe_auditor
a11y.text pipe_auditorThe pipe_auditor scanner will determine what named pipes are available over SMB. In your information gathering stage, this can provide you with some insight as to some of the services that are running on the remote system.

Now that we have passed credentials to the scanner, the Linux box doesn’t return the set of users because the credentials are not valid for that system. This is an example of why it pays to run a scanner in different configurations.
