Installing full Linux from Windows on USB with persistent storage

This guide will describe how to install a full Linux OS on an USB flash disk with permanent storage feature, i.e. the system does not lost your files after a reboot as usual live distribution does. The system is fully operable OS and transferable to any PC with all your installed and saved stuff.

There are several ways how to do it, for example using two usb keys, or making a bootable live USB key and then performing the installation (as is for example decribed here How to Install Linux OS on USB Drive and Run it On Any PC ).

Tools for a quick SIP diagnostics – ngrep, sipgrep and sngrep

Sometimes there is a need for simple and quick analysis of a SIP server and its call functions. Of course, we should use the well-known tcpdump, mentioned in the article Using tcpdump for SIP diagnostics. However, for some occasional Linux users this may be too difficult and unclear. But actually there exist some simpler utilities, that could work fine, as ngrep, and for me newer, sipgrep and sngrep (love at first sight).

All utils are directly available and can be installed online from Debian repo using apt-get install ngrep sipgrep sngrep.
