Re: Tools to scan for subdomain

[Ed Donahue <ed () 2dum com>]

You can get a list of subdomains through a zone transfer command to the  
nameserver.  Using the linux host command ('host -l'), you can list all  
the subdomains in a given zone.  However, zone transfers are typically  
limited to only slave nameservers that are replicating, so you will  
most likely be denied a zone transfer list.  If you do receive one,  
then the administrator setup the nameserver insecurely (or feels  
nothing can be gained through others having this list).

Google is your friend.
