Powershell LSOF / Parsing Netstat

Update 09/14/2012:

Other attempts at an lsof for Windows are here:

• thinking-about-network-security.blogspot.com/2010/10/powershell-lsof-parsing-netstat.html
• thinking-about-network-security.blogspot.com/2010/12/powershell-lsofparsing-netstat-part-ii.html
• thinking-about-network-security.blogspot.com/2010/05/lsof-for-windows-subsitute.html

These are very 1.0 and 2.0.  I will try to update my lsof attempts to 3.0 soon.

This script, parse-netstat.ps1, successfully parses 'netstat -ano' for each PROTO (TCP,TCPv6,UDP, UDPv6) and then uses 'ps' to enumerate ID,NAME,PATH,FileVersion for the process associated with each networked PID. Thus we have a basic Powershell LSOF utility with room for calculated properties and additional text parsing. There is no spec of regex anywhere in my text parsing of netstat.  Sample output:


PS C:\ps1> .\parse-netstat.ps1
