Scanrand is extremely quick and effective port scanner. It works by forking two distinct processes:
- One to send the initial queries
- One to receive responses and reconcile them from the above
This makes it extremely fast.
If you haven’t heard of the suite, Scanrand is one of the five tools in Paketto Keiretsu by Dan “Effugas” Kaminsky of Doxpara Research.
Scanrand implements numerous options; reasonable defaults are selected when no specific guidance is received from the user. The only thing mandated is a target destination, which may be specified using either a FQDN(Fully Qualified Domain Name) or a numeric specification.
These numerics may employ any number of dashes, commas, or combination thereof at the same time. For example, scanrand 10.0.1-255.1-10,20:80,137-139 works fine.
More ports will be scanned by default when scanning a single host than when sca
nning a network. Scanrand is able to estimate remote hopcount by examining incoming TTLs.
Note please to install scanrand you need to first install the provided libnet, libtomcrypt and libpcap tarballs.
It’s a good alternative to nmap for certain purposes
