Yesterday I was looking for some webtools that could run nslookup and other network tools. I was not able to use these (because I was at a site which had provided me with a Microsoft workstation and used proxy servers that ban network tools).
The tools include:
- Browser Sniffer
- Web-based Dig
- IP Calculator
- Probe Remote Host
- Online Quizzes
- TCP Dump Interpreter
- Terms and Definitions
- Online Whois Tool
- Fingerprint Remote Host
- Online Traceroute
I tried the browser sniffer, and the script ran an impressive array of tests. It is quite scary what a sniffer can discover from a GUI browser running on a Microsoft machine.
Dig (domain information groper) is the well-known DNS-lookup utility. IP calculator is for netmasks. Probe remote host, offers information on Domain/Network and DNS records. It also offers Port scan and Traceroute.
I tried nslookup on my site:
After the problems that had been reported by Steve (in Canberra) I tried Tracerouting to www.pgts.com.au from RingOfSaturn using TCP packets...

All looks ok to me ... bit slow ... but ok? The online quizzes consists of 19 tests on:
- Basic HTML
- Building Cisco Mulitlayer Switched Networks (BCMSN)
- Building Cisco Remote Access Networks (BCRAN)
- Building Scalable Cisco Internetworks (BSCI)
- Building Scalable Cisco Networks (BSCN)
- CCNA Practice Quiz 1
- CCNA Practice Test
- Cisco Internetwork Design
- Cisco Internetwork Troubleshooting
- Designing Cisco Networks (DCN)
- International Domains
- Mutt and PGP
- Subnetting Class B
- Subnetting Class C
- Unix Commands
- Using Traceroute
- Whois, Dig, and Nslookup
The tests on Cisco look very tough, or at least they do to someone who like me who knows very little about Cisco routers. I took the test on Subnetting class B and got 90%. (oops -- I didn't know the answer to the last question -- oh well I am a self-taught network administrator) Most embarrassingly I only got 90% on the "vi" test (I clicked on the wrong box -- even though I knew the correct answer. Typical for someone who is over-confident!)
This is a very good site, and obviously built by an experienced administrator. I heartily commend it to anyone who is looking for robust, fast online network tools. It happens occasionally ...
I'd love to be able to say that http://networking.ringofsaturn.com/Tools was W3C, but sadly, they did not pass.
But while I was surfing I came across a blog called Postneo 2.0, by Matt Croydon. This, while I was surfing for blogs to give me a few ideas. Great blog, well maintained and current. It gives me something to aim for ... I don't know how he finds the time though. Also he may have found the right niche (Apple) In the meantime, I will add it to my list of bookmarks.
Also for those who really want to "Get The Facts", you could start here for Novell's counter-punch to the Microsoft "Get The Facts" FUD.
