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 ...

MEWU - Scene 4 ... GUI Firewall ..

Hmm, like all you know , Linux is comparatively safer then other dumb OSes ... ( do i need to name 'em ?? ) ... so linux is not required to have an AV products ... also , It has built-in Firewall , which is Ip-Tables ...which are basically rules written manually !!! , but its little difficult for "common guy" like me to write syntexes and codes .. ah it just makes me nervous ... so i prefer more GUI ... well you can say its "side-effect" on me due to overdoze of "window" medicine !! ... so this front-end software is very handy for me ... they call it .."fire starter" ... sort of ..

Well, Firestarter is basically just a front end ... it still uses Ip-tables as back end .. means , since Ip-tables are little geeky to use, Firestarter makes life eazy by providing Graphical interface of Ip-tables !!!




we can install in via , synaptic manger ... just search for "firestarter" and you get it !!!

or in terminal type ..

sudo apt-get install firestarter

it will work fine too ... at first time you will be needed to provide the name of interface for which you want this firewall to work ... i use wifi mainly so i had chosen, ATH0 ( i think, ath0 is for atheros cards only !!! ) ... and you are all set ... but again , this GUI doesn't load on startups ... ( don't mix gui with original firewalls ... because the Ip-tables itself gets loaded once n/w gets established but in deamon/background ) , so to start firestarter at startup you can do any way you like , but the way i preferred is through , system -> preferances -> sessions , in startups , ADD , choose name and description as you like , and for command , write ,

gksudo firestarter

so , next time when you will boot , it will ask for password when it will be loaded i think its more safer option then just setting such a way that it doesn't ask for password ( still you need to save your password somewhere to make firestarter start automatically !!! , because thist s/w itself needed to have root privillage ) ...

free PDF converter ....

Perhaps , the acrobat reader is one of the most downloaded junk on internet ... But it doesn't allow you to create PDF documents ....

you may ask ... Why need PDF document ? ... well , one of the reason is , with its help you can create document a bit difficult to edit for others ... also they can't simply just copy and paste your document for their use .. ( if you have disabled that function ) ...


But to make a pdf document , you are needed to buy adobe acrobat , sure that i don't want to do ... this software .. "doPDF free converter" is fine for me .... doPDF is a PDF converter for both personal and commercial use. Using doPDF you can create searchable PDF files by selecting the Print command from virtually any application. With one click you can convert your Microsoft Excel, Word, or PowerPoint documents or your emails and favorite Web sites to PDF files. doPDF installs itself as a virtual printer driver so after a successful installation will appear in your Printers and Faxes list.

MEWU - Scene 3 ... Playing with DOCK

Well , people who use MACs , must be loving its famous "dock" thing ... and i am sure that windows lovers must be feeling jealous for that dock in Macs , though they can enjoy same dock feature for windows too but still its not native application ... they need 3rd party softwares like "rocket dock" or "object dock" right ??

It's true for linux / Ubuntu too ... here they use software ... "Cairo Dock" which is perhaps the most common and most famous dock around ubuntiens !!! ... but it is not available by default in synaptic manager , we have to add 3rd party software string ...

deb http://repository.cairo-dock.org/ubuntu gutsy cairo-dock

and then , click on reload in synaptic manager ....and then seach "cairo" in it .. it will show cairo dock now ... but don't forget to choose both "cairo-dock" and "cairo-dock plugins" .... and apply .. and dinggggg , you are done .... if you prefer a bit harder way , then take a look at this official ubuntu help ...

launch it via , applications -> system tools -> cairo dock ...



But here comes one problem ... it will not launched automatically again when system is rebooted !!! ... to do it ... go to system -> preferances -> sessions , in it "startup programs" and just click on "add" , and write what ever you like for name and comment , but in command type "cairo-dock" ( ofcourse without quotes.. ) ... and it will be launched automatically with every reboot !!!


enjoy ....
