Discovering hostnames

Hello,

 

I've been having a hard time detecting hostnames on Linux and Unix Systems when I run maps. I'd like to know how to configure our scanner appliances to perform reverse DNS procedures and gather those hostnames.

 

Can any of you help me?

 

Thank you!

    Discovering hostnames

    The scanner automatically performs reverse DNS lookups on an IP address.  If the DNS server supplied to the scanner, doesn't have the host name of that IP - there will be no data.  If you supply a primary and a back up DNS server, we attempt to contact the primary first.  If the primary is up, and it doesn't have the record, we report no host name.  If the primary is down, we shift to the secondary.

     

    Are these devices listed on your internal DNS server?
