	Using Windows Installer

	Windows Installer Features
	Python 2.5 is distributed as a Microsoft Installer (MSI) file on Windows. Typically, packages are installed by double-clicking them in the file explorer. However, with the msiexec.exe command line utility, additional features are available, like non-interactive installation and administrative installation.
	Non-interactive Installation
	With the command line
	msiexec /i python<version>.msi
	installation can be initiated programmatically. Additional parameters can be passed at the end of this command line, like
	msiexec /i python-2.5.msi TARGETDIR=r:\python25
	Limited user interface

tuantm8 / Security Onion installation

Created August 9, 2017 10:08 — forked from cleesmith/Security Onion installation

Security Onion installation in a virtualbox

	Security Onion
	Aug 2014:

	... my purpose for installing this was to:
	- learn more about security stuff
	- steal the packet captures (pcap) provided so I can replay them using tcpreplay for snort testing,
	as it's not so sexy to just test using ICMP ping data or local rules that match anything

	see:
