Multi Threaded TCP Port Scanner allows you to scan 65535 TCP ports on an IP address. You can specify how many threads to run and the timeout. Furthermore, it will tell you the MAC address of the target and the services that are running. You can scan IP addresses on your network and find out which open ports you have.

Chaosmap is an information gathering tool and DNS, Whois, and Web server scanner. It can be used to look up DNS names with a dictionary with or without using a salt. Salting for DNS means it will append numbers from 1-9 to the name in the dictionary with or without a - and _ or a leading 0. Salting for Web stuff will try double slashes and some directory traversal tricks. It performs reverse DNS lookups of a whole IP range (with optional Whois lookup) and dictionary scans for hidden paths on one Web server or a range of IP addresses. Optionally you can encode a path with URL encoding use Google dict lookup mode to find the path on Google and only query the Webserver if there are no search results. It can also extract email addresses from domains using a Google search or perform a list of Google Hacking queries on your domain.

Qosmos NI_DUMP (“Network Intelligence Dump”) is Linux-based tool inspired by the popular tcpdump, enabling you to read, print, or save packet data related to traffic traveling over your network. Qosmos NI_DUMP is a light and versatile packet capture tool that recognizes 120 of the most commonly used protocols and applications, including SMTP, HTTP, MySQL, and NFs. This represents a small but useful sample of the full Qosmos Protocol Portfolio, comprising over 300 protocols and 4000 metadata. Unlike conventional packet dump tools, Qosmos NI_Dump can identify protocols using non-standard TCP or UDP ports, and incorporates an easy-to-use advanced filter expression language that enables users to zoom in on data of most interest to them, such as FTP transfers matching a particular filename or HTTP requests containing a particular keyword.
