Cool Tools: Network View - a network node discovery tool

Web Site: MailStarUSA.com

I'm not the only one who maintains this company's network. The operations guy is pretty capable and doesn't mind setting up PCs - he enjoys it. Well, between me and him we had lost track of PC, printers, WAPs, routers, more routers and such like that. We needed a network discovery tool and we found a great one by Michael Welschenbach at http://www.networkview.com/.

Network View pings specific addresses, a subnet or a range of IP addresses you specify. You can add nodes manually if you like. It can also scan a range of ports or just the most common ones such as SMTP, telnet and FTP. Information collected includes IP address, MAC address, NIC manufacturer (see Troubleshooting network connections with arp http://aplawrence.com/Unixart/dharp.html ) and hostname. SNMP information is displayed as well: Network View comes with over 5000 object IDs and you can add more if you have your own. SNMP is not available for Win 98.

Once you have all this information it can be saved in a file and printed out as well. The default format include IP address, NETBios/host name and the manufacturer of each NIC. The nodes can be sorted in several ways such as IP or MAC address or NETBios/host name.

Network View can monitor status and up and down events and can configure local alerts (.wav files) and email alerts. Discovery and event log files are kept.

Once a node is discovered you can right click on it and startup a Telnet, FTP, HTTP or even a VNC session.

Of course I tried Network View on my own network. I was curious to see which ports were open on my SCO Unix server (an old, venerable 486 with 16MB RAM). I scanned ports 1-1000 and got some very curious results. Ports 1, 7, 9, 13, 19, 21, 23, 25, 37, 79, 110, 137, 139, 199, 210, 457, 512, 513, 514, 515, were all alive. This was rather surprising to me - so I wrote an article about it. Network View is not a complicated tool, but performs it function very well indeed. It's definetly going to be a part of the computer nerds toolkit. This tool is Windoes shareware (30 days/$59).

A nice tool that I have used on a Linux machine, can be found here: http://cheops-ng.sourceforge.net/

And if all else fails, manual documentation of network resources still works.

Well,assuming it was done and that you can trust it.. I'd rather scan.

Well, one of us documents and one does not....

I use (link) spiceworks. Its a new network discovery and monitoring tool. It also does monitoring, trouble ticketing and reporting so it works well for my 150 node network. Plus its free. It doesn't do a ton of deep SNMP scanning, but seems to handle VOIP, HTTP, WMI, and SSH pretty well.

I am reasonably certain that the above comment about spiceworks was posted by spiceworks. We tried it on a 150 node network and it was absolute trash. Stick with the big guys

I liked it but it was a very slow scan

I use spiceworks as a monitor, it does ok on network mapping, the real jewel is in the end-user plug-in's for the app. It is a by tech for tech software, as is, so of course as any freeware it has bugs. However, that being said, I have been able to use it successfuly on our networks. It is what it is, a free application - its worth trying, but is not an out of the box solution, you will have a lot of setup, however if your network is over 200 units I suggest at that point pressuring the purse to buy a full "Paid system." For smaller networks, or meshed networks it works great. FYI I currently use it on a system with 127 points, across a mesh and with 4 subnets, 2 remote vpn sites and it works fine - but again it was a lot of configuration.
