Linux Guide to Free Tools for Network Engineers E-mail
Linux HowTo's - Linux Networking HowTo's

Being and Network guy I had this idea (or if you speak to asanabria, he'll probably say he had this idea) to show off the free tools built into that Linux that will help you in your day to day duties.

Now if you've already gotten familiar with Linux, you have an inkling of what's to come. If your new to Linux, you've got some treats coming your way! The Linux guys in your shop will be familiar with a number of these tools, but there will be some that are not in the typical SysAdmin's toolkit.

Since I'm running around doing chores today all you get - for the moment - is a little tease. Check this out.

 

**Note the first octet of the ip address has been changed to protect the innocent. Ok well actually so you can't find the LinuxDynasty cave just yet.

 

[root@YeaBaby ~]# nmap -sP xx.115.218.0/24

Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2008-05-25 16:13 EDT

Nmap finished: 256 IP addresses (10 hosts up) scanned in 4.002 seconds

So I just scanned my local network for hosts that are up without buying anything,  or getting one of those cheesy free software trials that run out just when you need the tool. NMAP is free to use forever.

We're going to get more in depth with "NMAP" in part one of the  "Linux Guide to Free Tools for Network Engineers" series. So check back frequently you cheapskates. And we will gladly accept a percentage of that bonus you get for saving your company soooo much money - if you insist.
