S2W8 Wednesday: Network Tools, Facebook Truth, Piracy, Password. Professor Teaches

__________________
1. Network Tools - Using Whois, Tracert, Ping

TCP/IP comes with an array of simple tools to monitor networks. Usually you would access these via a command line (prompt), but because you cannot do so here I have provided links below to websites which offer these tools through a web interface. Here is a list of important tools for managing IP networks. Try out the domain dossier, ping, traceroute and analyzepath to see what they offer and then leave a comment on your findings:

Investigate domains and IP addresses. Get registrant information, DNS records, and more.
Domain Check
See if a domain is available.
Email Dossier
Validate and investigate email addresses.
Browser Mirror
See what your browser reveals.
Ping
See if a host is reachable.
Traceroute
Trace the network path from this server to another.
NsLookup
Look up various domain resource records with this version of the classic NsLookup utility.
AutoWhois
Get Whois records automatically for domains worldwide.
TcpQuery
Grab a web page, look up a domain, and more.
AnalyzePath
Do a simple, graphical traceroute.



Here are a number of links to sites which offer these services:





You can perform an online traceroute above or install the network tools software located on the server under
 
Secondary/Curriculum/Computing/Software/Visualroute


Other popular tools include port scanners - these are used by hackers to identify open ports in a network which they can utilise. 


 How Traceroute Works?  

Traceroute is used to trace the path that datagram traverses to reach its destination. It gives one path from point of origin of data packet to its final destination, there is no assurance that data will travel same path each time. Mostly all Unix like operating systems provide traceroute tool, Tracepath is available in latest Linux flavors and Microsoft OS provides tracert tool.  Traceroute command uses ICMP utility to trace the location of each router. TTL value represents the number of nodes (routers or gateways) a data packet can travel.

It's interesting that we can do all of that with those websites... but all of that information means absolutely nothing to someone like me. Still pretty cool, though.

I found it really funny that someone thought that the more space they had on their hard drives, the more heavier they were haha. Sometimes I wonder if people post that sort of stuff as a joke or if they are being serious.

It looks really useful to a hacker and all, but I'm not a hacker so that stuff is just really coo looking words to me. Never thought that there were websites for this stuff.
