Path Analyzer Pro integrates advanced traceroute software (based on the open-source tool LFT) with performance measurements, DNS, whois, and specialized network resolution to help investigate network issues. It also supports geolocation, and can plot network paths on a map. People use it to research IP addresses, email addresses, and network paths, to graph protocol latency, jitter, and other factors, and to locate firewalls and other filters that may be impacting your connections.
Telconi Terminal is an unique network management application with interactive full-screen configuration editing, browsing, help facility support, debugging, and more. It focuses on common Cisco IOS functionality present with any hardware or software configuration, and complements the command line interface with a rich set of features. It is intended for users with knowledge of Cisco IOS, and is designed to work with any IOS-based device, such as routers and switches.
LFT (Layer Four Traceroute) is a sort of "traceroute" that often works much faster than the commonly-used Van Jacobson method and goes through many configurations of packet-filter based firewalls. More importantly, LFT implements numerous other features, including TCP, UDP, or ICMP-based traces, AS number lookups through several reliable sources, loose source routing, netblock name lookups, and more. LFT also distinguishes between layer-4 protocols, which make its statistics slightly more realistic, and gives a savvy user the ability to trace protocol routes, not just layer-3 hops.
