MTR and WinMTR

MTR (My traceroute; originally Matt’s traceroute) is a free and open source Linux utility that combines the functionality of both traceroute and ping, and as such is a more sophisticated tool (go here to brush up on your knowledge of these two commands). Not only does MTR reveal each hop between your host and a destination (as traceroute does), but it also sends a sequence of ICMP ECHO requests to each hop to determine the quality of the link (like ping). Simultaneously it displays running statistics about each hop. MTR supports both IPv4 and IPv6.

The simple command syntax for MTR is mtr [options] [target]. The range of options for MTR is described below.

Troubleshooting faulty network connectivity, part 2: Essential network commands

In my previous article describing the troubleshooting steps for faulty TCP/IP connections, I mentioned several commands such as ping, traceroute, and ipconfig that could assist you in pinpointing problematic network components. These commands and several others like them are commonly referred to as TCP/IP utilities because they are tools that let you perform diagnostics and queries on the network which you are examining.

To compliment Part 1 of this two-part series, Part 2 is a reference list of the TCP/IP utilities which will describe the intended uses and options for each. These tools natively run in command line interface (CLI) environments (or in Linux and Unix, “shell prompts”), but as several entries in this blog show, there are a great many graphical utilities available that let you use the TCP/IP utilities (and view their output) in graphical format. In this article, however, I will stick with the default CLI usage and functionality.

Remember: the best way to learn and understand these tools is to practice with them. Also bear in mind that knowledge of these commands is often essential during ethical hacking efforts and for networking certification exams.

Northwest Performance Software’s NetScanTools Basic

NetScanTools Basic Edition is a free graphical utility for the following network query commands: DNS (simple IP/hostname translation, Who Am I? (shows your computer name, IP and DNS servers)), ping, traceroute, and Whois. It runs on modern versions of Windows (XP, Vista, 7, 2003, and 2008).

As NetScanTools Basic is intended as a stepping stone to Northwest Performance Software’s other commercial products, it is comparably slimmed down and limited in its functionality. NetScanTools Basic v2.30 was released on Sep. 4, 2013 and was the latest version available at the time of writing.
