Technical writing - Articles - tutorials about Networking, IP converting, etc.

I would like to have 1 or 2 articles with tutorials.

The articles must be 1000 words minimum.

The topic must be IP addresses, networking, how to.

For example:

HOW TO SNMPWALK A DEVICE

NMAP - HOW TO FIND OPEN PORTS

NMAP - CONVERT OUTPUT XML TO CSV

CONVERT CIDR MANUALLY IN BINARY

These articles are already written. I need something of the same fashion.

Please provide a quote for 1 or 2 articles.

Please choose titles that are interesting for people, that are needed and searched - SEO is important too.

Price per article! Not price per hour.
