TCPView - Free

When you need to know what ports your develepors' latest custom app uses on Windows, and no one one their entire team has a clue but they still expect you to fix the firewall to allow "their" traffic anyway because they are supposed to be in production in less than 24 hours and they are just now getting around testing the app in the final production configuration.

"It always worked on our other clients' networks with no problem. Of course, our implentations were smaller there..."

or

"It was custom written for us 8 years ago and was designed to run on '95 over IPX/SPX, but our new large production process that we are about to roll out needs this to work until the second phase deployment when we'll be updating that piece. We've thrown together a hack to get it working over Winsock on TCP/IP, but I don't know what ports we're using..."

or

"I'm not sure what the names of the exe's are that are supposed to be waiting for incoming data, not to mention which ports they use."

I hate those phrases.
 
I haven't read the entire thread, but I noticed Servers Alive was listed as "trial", that is incorrect, you can use SA to check up to 10 things for free and it is fully legal to use it in that manner.

Of course once you realize how great it is you'll be checking hundreds of things accross LAN/WAN so you'll end up paying for it anyway :D
 
Is there a free, simple version of something like this that maps out networks and creates charts?

3COMs Network Supervisor is a pretty good tool for getting a picture of new/strange networks you're taking over.

GFI Languard has the ability to look past SecureClient Firewalls and ping a device to see if one exists. This is useful for scanning IP's to be sure a 'rogue' hasn't stolen it prior to it being assigned as a static.

Only problem is, for that one purpose, GFI is like hitting a small nail with a really, REALLY big hammer.

I'm looking for a new, small, free, simple scanner that can look at an IP and tell me if anything is there, and what it is (printer, Netbios name, etc...) but it also has to be able to get past the ICMP block in SecureClient.

I have no idea how GFI does this, but it does.

In my experience LANGuard is deployed more so as a way to check up what your server has installed (or not installed), example would be security patches, what ports are open, services running, etc. Look@LAN has always been used as a monitoring tool for what your servers and network devices are doing and how they are performing (more network stats than anything else).

GFI is a great company as far as support goes. I cant speak for Look@Lan support as I have never had a reason to ping them about anything.

Is there a certain functionality you are trying to obtain or are concerned about?

All my attempts to get Network Supervisor result in a page saying the product is discontinued. Am I just missing something?
 
Everyone's listed all the good ones above. But i use this for anything i open.

ConTexT
http://www.context.cx/

Great Text editor for Every and anytype of file. Php,WSH,C+,.ini etc etc..
 
for the most part, you guys are covering all the basics that i use...

FREE: http://www.rejetto.com/hfs/ nice super simplistic and extremely small footprint HTTP server...

FREE ( + windows licence): http://www.nu2.nu/pebuilder/ its sooo time consuming, but so incredibly powerful... BARTPE, very customizable, i like to create nearly stock disks with as many network drivers as humanly possible on it, then put the simple programs i use for backing up or checking volumes on it, add ghost32... its like bartpe and ghost32 were made for each other

FREE: http://www.yadabyte.com/Yadabyte_Portables.php yadabyte passwords, i know password managers are lame, but i like the simplicity and security of this one... it is a lot safer than using a handful of passwords over and over again... and it is a lot easier than reregistering on websites that you've forgotton the password for... AND cold booting networking hardware that you've totally forgot the username or password for

most of the others you guys already mentioned... some of my favorites are netstumbler, filezilla, angry ip scanner, and a few very simple tools i wrote up in VB to automate the editing of some network settings in the registry
 
Everything else is already listed above, but living in a college dorn with 120 other computer and software engineers, I must recommend XArp (free!) for anti-arp poisioning attacks. Unortunately (and in cases fortunately ;) ) Cain has made it far too easy to execute an arp poising attack (from windows anyways). This is the simplest tool I have found to at least alert you to its occurence. Of course, my solution has always been static arp tables, but it's nice to know what's going on anyways.
 
Wireless intrusion detection AIRSNARE


"AirSnare is another tool to add to your Wireless Intrusion Detection Toolbox. AirSnare will alert you to unfriendly MAC addresses on your network and will also alert you to DHCP requests taking place. If AirSnare detects an unfriendly MAC address you have the option of tracking the MAC address's access to IP addresses and ports or by launching Ethereal upon a detection"

You are assuming I and others actualy have a head.. :) ,and when you deal with 255.255.255.0 98% of the time you actualy find them usefull. (Yes I can do it by hand but why when you have a computer)? It's like saying I know Pie out to the 30'th digit. It's usefull, but why clutter the brain with that info. Mid 80's sitcom trivia is a much better use for that storage space. (god I wish I could forget that stuff)

How do you like Observer. I am working for a telecommunication company. We mostly sell Shoretel VOIP systems and I am trying to locate a good VOIP analyzer software. We currently use VIOLA, but it is pricey and only tells you if you pass or fail the VOIP test and I would like a software that can atleast show me where a potential problem is.

eh.. why limit yourself to only C&A? there are many other security tools out there, and there is so much more yet to be done.

Learn C, and start creating your own security tools:)
