MEWU - Scene 5 ... Playing With Shark !?!?

Owww, its not that always hungry long saw toothed terrifying wild creature from that movie JAWS .... its just a network analysis tool, Wire Shark , but its just same powerful as jaws of shark !!!... it is widely used to understand how internet itself that is , hidden behind web browsers and messengers and lots of other web based applications ... it shows us the way how protocols are stacked up or what protcol messages are interexchanged between client and server , when we do any kind of network transactions ...

Wireshark has a rich feature set which includes the following:

• Deep Inspection of hundered of protocols, with more being added all the time
• Live capture and offline analysis
• Standard three-pane packet browser
• Multi-platform: Runs on Windows, Linux, OS X, Solaris, FreeBSD, NetBSD, and many others
• Captured network data can be browsed via a GUI, or via the TTY-mode TShark utility
• The most powerful display filters in the industry
• Rich VoIP analysis
• Read/write many different capture file formats: tcpdump (libpcap), Catapult DCT2000, Cisco Secure IDS iplog, Microsoft Network Monitor, Network General Sniffer® (compressed and uncompressed), Sniffer® Pro, and NetXray®, Network Instruments Observer, Novell LANalyzer, RADCOM WAN/LAN Analyzer, Shomiti/Finisar Surveyor, Tektronix K12xx, Visual Networks Visual UpTime, WildPackets EtherPeek/TokenPeek/AiroPeek, and many others
• Capture files compressed with gzip can be decompressed on the fly
• Live data can be read from Ethernet, IEEE 802.11, PPP/HDLC, ATM, Bluetooth, USB, Token Ring, Frame Relay, FDDI, and others (depending on your platfrom)
• Decryption support for many protocols, including IPsec, ISAKMP, Kerberos, SNMPv3, SSL/TLS, WEP, and WPA/WPA2
• Coloring rules can be applied to the packet list for quick, intuitive analysis
• Output can be exported to XML, PostScript®, CSV, or plain text

To , install it in Ubuntu , search synaptic manager for "wireshark" , and select to install it ...
Or, type ,

sudp apt-get install wireshark

it will work fine too ... but to run wireshark you must be needed to have administrator privillages .. because without administrator privillage you will not be able to get any interface to capture packets .... so , to run it , you have to type at terminal ...

sudo wireshark

and it will work just fine ....



that is it , have a good play with shark ...

njoy ...
