Unix & Linux: Linux network troubleshooting and debugging


The Question: From time to time Linux and Unix users faced with various network problems.
Many of these problems are presented here and at some others troubleshooting
forums, but they are very concrete and contains a lot of additional technical
information, and sometimes it's rather difficult to understand the main point
and the real reason of buggy system behavior.
By asking this question, my intention is to start a community wiki page which
allows generalizing our network troubleshooting and debugging experience. I
hope the Linux and Unix users could easier recognize and solve("divide and
conquer") their network problems using this page.
The parent of this page should be https://unix.stackexchange.com/questi...
2619/best-practise-to-diagnose-problems. But here we should focus on
troubleshooting the network problems from user- and kernel-space.
I suppose, if you:
1. Share the information about using some great network diagnostic tool with
concrete usage examples and examples of network bugs, which they help to
catch.
2. Share the link to the great network tutorial connected with this subject
3. Tell about a general method or recipe which allows to tackle some class
of network problems
4. Share information about your tool-set for network debugging and
troubleshooting
it would perfectly fits for this topic.
----
I'll begin from sharing the link to varios http://www.thegeekstuff.com/2011/12/
linux-performance-monitoring-tools/ and 12-years_old_simple_tutorial. Also
archlinux_tutorial seem to have actual information about our subject. And for
diving into linux networking we definetely need to visit Linux_Networking-
HOWTO.
