CHROME INSTALLATION ISSUES IN UBUNTU : SOLVED

1. Recently tried installing Chrome browser in Ubuntu 11.10....so I downloaded the .deb file and tried installing it from the terminal via this command

sudo dpkg -i './Downloads/google-chrome-stable_current_i386.deb'

...which showed some error in between installation and came out on the terminal prompt....

2. So googled and found this solution that involves prior installing of few library files as follows :

sudo apt-get install libnspr4-0d libnss3-1d libxss1 libcurl3

this command will install the missing lib files and then on it is the repeat of the earlier command ie

sudo dpkg -i './Downloads/google-chrome-stable_current_i386.deb'

3.   Should solve...let me know if u have any thing unsolved!!!

AVOID OPENING MULTITABS IN BROWSERs

1.  Has it ever happened that you get a mail in one your various Email IDs from Facebook or some other site that you never linked up with....?I am sure if you are a regular browser on social networking sites,this must have happened once...and it must have kept you thinking...HOW ??

2.   This happens when you have that email id open in some other tab and your Facebook account open in other...typically in a multitab session wherein you have opened many sites under one browser in various tabs..... that's when info gathering sites get your email id and things related to their interest.....TAKE CARE

BACTERIA in COMPUTERS

1.  I had heard for so long about Virus'es,worms,trojans................but never heard and read about BACTERIA till recently.....even googled...could not find much except at http://docstore.mik.ua/orelly/networking/

2. Few points about BACTERIA :


- Makes copies of themselves to overwhelm a computer system's resources.

- Also known as rabbits, are programs that do not explicitly damage any files.

- Sole purpose is to replicate themselves.

- May do nothing more than execute two copies of itself simultaneously both of which may copy themselves twice, and so on.

- Reproduce exponentially, eventually taking up all the processor capacity, memory, or disk space, denying the user access to those resources.

- One of the oldest forms of programmed threats.

Download/Upload torrents - Legality Issues in India


1.  Read the following daily life talks in the air now a days :

"Hey did u download Agneepath & TIN TIN....the torrent is available now?"...

"No...its the cam print"..."waiting for the better print...yeah but I have downloaded MI4....the new torrent is crystal clear"

"MS Office 2010 has come and I m already using it on my netbook...& its for free from torrentz..."

...etc...etc...

.......these are few exchange of talks that invariably happens more among the young metro crowd and also getting popular in the Viltro's (Village+Metro)........but did they ever realise the legal aspect of all these talks and downloads? Its time to check all this......RETHINK!!!

2.   Now any one of you reading this and finding himself at some point of time shooting these dialogues at home/office/college should be in  for a shock...because as per the IT act he is a criminal involved in piracy of softwares and movies.

EXTRACT FROM INFORMATION TECHNOLOGY ACT 2000

"Cyber crime is criminal activity done using computers and the Internet. This includes anything from downloading illegal music/movies/softwares files to stealing millions of dollars from online bank accounts. Cybercrime also includes non-monetary offenses, such as creating and distributing viruses on other computers or posting confidential business information on the Internet"

3.  So now that you have read this....the meat is here as follows given in point form for ease of understanding :

- When you download a movie/music/software from a torrent site,you are not only a leecher but at the same time you seed also.A Seed is used to refer to a peer who has 100% of the data.

-  When a leech obtains 100% of the data, that peer automatically becomes a Seed.Seeding refers to leaving a peer's connection available for other peers, i.e. leeches to download from.
- Normally, a peer should seed more data than leech. But, whether to seed or not, or how much to seed, is dependent on the availability of leeches and the choice of the peer at the seeding end.

- Did u understand this much...if not simply put it means that when u download....you upload also at the same time...so u are a illegal downloader and also a uploader of the pirated illegel content.So suppose you have downloaded MI4 or some porn...you are a pretty much proven criminal.If someone gets after you,you are in for real damage.

4. In context of India,though the relevant cyber laws and framework  are ready and already implemented but it will take time to be actually possible for the law to follow each one of them them up individually....thats the only positive side of all illegela downloaders...but there is catch to this...

5. What happens if some other country watches you?....you must be thinking y would some other country watch you downloading agneepath/TIN TIN!!!this is because your uploading may be happening in their country...so all they need is your IP.Thats the end of it.Few major casualties include the famous Lt Col Jagmohan Balbir Singh, who was arrested on May 6 on the charges of circulating child pornography on the internet.The Mumbai Cyber Crime Cell arrested this Lieutenant Colonel from his south Mumbai house for allegedly uploading obscene photographs and video clips involving children on the internet.The German police came across the obscene contents being uploaded on a child pornography site from Mumbai in 2009.So this is where the string of the torrent catches you till end.The german police gave the IP to interpol and he was caught...unawares of what did he actually do?...now it is just unawareness on such issues that such things happen..

6. This time it was a Lt col...next can be any one....u and me....it depends won who is the (un)lucky one...so guys if u r an ardent torrent downloader...think before you do some thing next.....the days are not far when all this will land you up in jail....it is just a matter of time in INDIA..!!

Security Design @ WebHosting

1.  At a time today when new websites are being hosted at quite a pace,proportional is the pace of hacking and defacing of these websites.Today you have a website maker in the market who may simply demand some Rs 500/ per page design and few more hundreds for hosting it...and we all are ready to do pay him....but at what price....is it simply the final handing over taking over of the password that closes the deal between you and the designer/hoster?....NO....I rate it equivalent to the toss....thereon the match begins.....just a matter of time depending on what all security parameters/variables/factors you took into consideration while designing it?

2.  Specially concerned with web sites who have E-Commerce and transactions or who deal with handling database of huge sizes which can be critical later on, if compromised any time.The following factors should be noted down and infact dealt with seriously to be kept on high priority while designing and final hosting :

- Password /Data Protection : You must have a sound password and methods to protect all the DATA in place.

- OS/Server hardening : You use a windows or a linux....rest assured you must always used a hardened OS/Server.

- OS Selection : Create and design on any OS...today you can launch it on web.A more vulnerable OS which has had a history of hacks and known exploits should be avoided.

- DDoS Protection : Shared hosting servers are vulnerable to attacks by hackers who carry out their work by uploading malware or otherwise malicious sites or code onto a server. These malware programs be introduced to a server through security vulnerabilities in a legitimate client’s site, and the malware is used for anything from stealing credit card data to launching a DDoS, or Distributed Denial of Service attack.So think before you fire up your site.

- Spam filters : No explanations

- Firewalls : Must...so many types in market : Decide like what you r going to select a HARDWARE FIREWALL or a SOFTWARE FIREWALL.The selection is of crucial significance in deciding the overall security rating!!!

- BACKUP : You must have a way to keep backing up all your data.Some ploicy should be designed of what happens if owing to some kind of reason you loose all ur data....mirror or offline backup!!!!anything...but keep in mind.

- SSL enabled server : MUST

- SFTP: Though FTP is not that bad....but when SFTP is there....y bank on a relatively lower secured protocol......

SURF SAFE : SURF http'S'

1. In our endeavor to safely surf the web,rest assured ....we will never be safe in recent times to come.But we can always keep improving our surfing habits so that we are not easy victims.

2. Using HTTPS, the computers agree on a "code" between them, and then they scramble the messages using that "code" so that no one in between can read them. This keeps your information safe from hackers.

3.  As on date almost all the browsers offer plugins from their respective web stores that include what I am talking about here ie HTTPS ENFORCER.The HTTPS Enforcer extension makes it easy to ensure you’re connecting to secure sites by rewriting all requests to an HTTPS URL whenever you visit one of the sites HTTPS Enforcer supports.

4.  So install HTTPS plugin for ur respective browser...and SURF SAFE.

EVERCOOKIE : COOKIE NEVER DIES

1.  At my earlier post here,I had given a one line info on Zombie cookie-The cookie that recreates itself once deleted.Now just read about EVERCOOKIE at a veri good compiled site at http://samy.pl/evercookie/

2.  Evercookie is a JavaScript-based application which produces zombie cookies in a web browser that are intentionally difficult to delete.

3. More at http://samy.pl/evercookie/ with good FAQs

PICTURE PASSWORDS

1. Had read about picture passwords in theory....but was unclear of whats actually in store.Windows 8 has finally given the answer.....this video would be able to give you very clearly of whats the buzz about PICTURE PASSWORD....



DISCONNECT & CONNECT TO RAJNIKANTH POWER : WEBSITE RUNS WITHOUT INTERNET

1. The only thing that has ever found a mention in my blog ever apart from any technical stuff is about RAJNIKANTH here since I am one of his huge fans.Now this time he makes a entry in my blog not because of his charisma....he is here owing to the fact he has beaten the basic internet requirement....A WEBSITE THAT RUNS WITHOUT INTERNET.

2.  Yes! you have read it right. A man as extraordinary as Rajnikanth ought to have a website that's as extraordinary as him. "All About Rajni" the site dedicated to the legendary superstar runs without the Internet; albeit on RAJNI POWER!


3.    How does it run then technically speaking? It is attributed to some complex algorithm running in the back-end that keeps an eye on the propagation of data packets between two terminals.What does that mean anyway?....may be it downloads a small flash file the moment you hit the site in the background....anyways its just a guess.....if i come across the details...will let u know...till then enjoy RAJNI POWER on the net.

4.   Access this site here : http://www.desimartini.com/allaboutrajni.htm

4. Thanks http://www.thehindu.com and my sister who told me first.

OS CLASSIFICATION


1.  We keep using so many OS's around in office,at home...some times windows...or a flavour of linux..UBUNTU..or the latest i touched upon was the upgraded BOSS..but was not aware that even OS have a classification.The classification is defined by Trusted Computer System Evaluation Criteria (TCSEC), a United States Government Department of Defense (DoD) standard that sets basic requirements for assessing the effectiveness of computer security controls built into a computer system. 

2.  TCSEC classifies any OS under 4 categories :

- D
- C
- B
- A 

3.  Few more things about the classication in point wise form :

- A has the highest security. 
- C, B and A are further classified as : C1, C2, B1, B2, B3 and A1.
- D defines Minimal protection
- C1 — Discretionary Security Protection
- C2 — Controlled Access Protection
- B1 — Labeled Security Protection
- B2 — Structured Protection
- B3 — Security Domains
- A1 — Verified Design
