[salina]

hello google groups i am just stating linux and now nothing...can u say me what is teh extension file for linux and do linux really don;t support .exe files....???if linux is free from .exe file the virus do exist in different form except .exe fiels..then what abt those types of files in linux...can anyone give me answer abt it??? 

[rhoit]

Dear Salina,
As the matter of facts extension really don't matter in linux
distribution. The file is identified with it header/Meta data.

http://en.wikipedia.org/wiki/Filename_extension
http://en.wikipedia.org/wiki/File_type
http://en.wikipedia.org/wiki/File_%28command%29
http://en.wikipedia.org/wiki/List_of_file_signatures
http://en.wikipedia.org/wiki/DOS_MZ_executable

Linux supports almost every file-system but ext* family in most
popularly used across various distribution. Read Something about file
system you might get much better idea.

http://en.wikipedia.org/wiki/File_system

The reason of the file permission is one of the major factor why even
the virus made for linux really don't effect in first hand.

http://en.wikipedia.org/wiki/Chmod
http://en.wikipedia.org/wiki/File_system_permissions
http://en.wikipedia.org/wiki/Linux_malware

I guess after reading bit of reading you will be expert in linux
filesystem in no time!

http://en.wikipedia.org/wiki/Computer_virus#The_vulnerability_of_operating_systems_to_viruses


While Linux, and Unix in general, has always natively blocked normal
users from having access to make changes to the operating system
environment, Windows users are generally not. This difference has
continued partly due to the widespread use of administrator accounts in
contemporary versions like XP. In 1997, when a virus for Linux was
released � known as "Bliss" � leading antivirus vendors issued warnings
that Unix-like systems could fall prey to viruses just like Windows.[31]
The Bliss virus may be considered characteristic of viruses � as opposed
to worms � on Unix systems. Bliss requires that the user run it
explicitly, and it can only infect programs that the user has the access
to modify. Unlike Windows users, most Unix users do not log in as an
administrator user except to install or configure software; as a result,
even if a user ran the virus, it could not harm their operating system.
The Bliss virus never became widespread, and remains chiefly a research
curiosity. Its creator later posted the source code to Usenet, allowing
researchers to see how it worked.[32]

It would be interesting to know why you want to use Linux in the first place. Can you please tell us a bit ?

[rhoit]

Dear Bishwa ji,
Its rather not a valid question to ask for the user to say why you want
to use linux except they wanna run some MICROSOFT GAMES!
The is no boundary for the usages of linux!
Regards
Rhoit

[awsiv]

I don't agree that it's an invalid question. I asked that question to  salina ji so that we can help her better understand the advantages of linux ... instead of just pondering about .exe files.

[Syangjali Thito Magar]

Yes Linux don't support windows .exe (executable files) But Linux do have Viruses ..... Moreover Linux is designed in a way to either avoid viruses or if one machine is infected, it try to immunize itself or don't let spread to other machine of network........ welcome to Linux / Open Source World (The Future) .... Best Regards :)

Hello FOSS-NEPAL,

 I am pretty new user of LInux. I recently installed CENT-OS 6 (86x64) on my toshiba-satellite notebook. The problem is that the mouse touch-pad does not seem to work properly. I can move the mouse cursor with the help of the touch-pad but the touch-pad doesn't function for clicks(single / double). Is there any package available for it(Synaptic Pointing Device)??? Any sort of information would be very helpful.

Thank you.

Bigyan Shrestha

[Syangjali Thito Magar]

Hi as a newbie I suggest better use distribution like Linux Mint,  Ubuntu,  Fedora ....... Linux Mint is all ready to go...

[bigyan shrestha]

Thank you Manoj,

Actually, I am using redhat for my work in the office and I don't want to get confused with the differences present in the distribution. So, I chose CENTOS for my laptop.

Isn't there any other solution to my problem ???

[amit shrestha]

@Manoj
 i just got curious about line: " Linux is designed in a way to either avoid viruses or if one machine is infected, it try to immunize itself or don't let spread to other machine of network"
I knew " Linux is designed in a way to either avoid viruses", but did not knew "it try to immunize itself or don't let spread to other machine of network" , how did you knew this?

[rhoit]

Dear Amit,

"ClamAV - The free Anti Virus solution for Windows on Linux"
I guess this statement will calarif your doubt!

Regards

[rhoit]

Isn't Linux virus-free?

For the most part, Linux is engineered in a fashion that makes it hard
for viruses to run (click here for more info). However, there are many
reasons you might want a virus scanner on your Linux PC:

[1] to scan a Windows drive in your PC
[2] to scan a Windows-based network attached server or hard drive
[3] to scan Windows machines over a network
[4] to scan files you are going to send to other people
[5] to scan e-mail you are going to forward to other people
[6] some Windows viruses can run with Wine.
[7] Linux virus infections are theoretically possible.

WHY? WE DO?
ITS JUST THAT WE DON'T WANNA FIX POOR GUY'S COMPUTER (mswin users) EVEN
IF HE REFUSED TO USE LINUX.

http://en.wikipedia.org/wiki/Linux_malware
https://help.ubuntu.com/community/Antivirus/

[amit shrestha]

no,   ClamAV  cannot be answer because it a third party software and i was talking about the code design architecture of Linux it self. 

In my opinion , there is no operating system free from virus mac,linux [ http://en.wikipedia.org/wiki/List_of_Linux_computer_viruses#Threats ]  ,windows . Its just , how secure is one form other. Linux and mac are more secure then most of windows OS. It also depends on user himself how he use the operating system . If one is always using system as super user then he is more like to get virus and it is true for both windows and Linux and mac. So at the end no matter how secure operating system is , in the end user also has to play his part.

[rhoit]

Dear Amit,

I guess you arn't getting the point. The Case is theoretically possible
when some one has the accesss to your system the enough privalage to do
some mischif.

And comes the Security! As hempal sir said - "Novice User's is the Most
safest User.", You can remove the case the Novice user will ever get
viruses.

If you presume people run linux as superuser does'nt makes him more
likely to be infected by virus because by default any external imported
to your system can't be exectuded (except using sftp or scp which is
entirely diffrent story).

Tell me the situation when the people try to send the exectables is
linux without using packet manager. Thats why it theoretically.

And if you manage to get viruses in Linux and make it spread to other
linux then you will be so called "One of most Genious people in the earth".

@bigyan
why don't you try fedora.

If you want a REAL solution against virus infection:

- Trash all mainstream AV (application blacklist solution)
- Install an "application whitelisting solution" (wiki, google)

[Syangjali Thito Magar]

@amit shrestha

It does immunize itself, one simple e.g will be :

If one machine ( Debain) got infected by viruses then it will not gonna infect other/ different Distros like Mandriva..... 

Multiple Linux package managers means that a Debian virus can’t infect a Mandriva system.

[Syangjali Thito Magar]

@bigyan shrestha

There will not gonna be that differences ( just some different windows manager, packages, configurations files locations / names, some commands etc.) & @ home i guess you not gonna be doing lots of server configurations & stuff.... 

But if you like identical distro. like Red Hat Enterprise Linux ( RHEL) & CentOS, Try Fedora

[Syangjali Thito Magar]

If you try Fedora, always remember you will get most of the latest stuff from Red Hat ( Fedora Projects is sponsored by Red Hat Inc.) But try to not to install all the latest / Beta ver. of software .. most of them will be unstable only install Stabled ver. of packages... 

& Fedora ( although its for client usage with most of Graphics, multimedia codec etc) ... its Red Hat R&D platform & mostly used by Developer 

[rhoit]

Don't ask! do and learn!

[Aks]

Just a few clarifications:

• All the software packages that end up in default Fedora repositories are not beta or unstable, they have been tested. Although you have the option to install alpha or under-test versions from the rawhide repositories. By most-latest, here, means that Fedora Engineering committe is dedicated in bringing the bleeding-edge to the distribution, but not without testing.
• Fedora not only brings latest stuffs from Red Hat, but from various Open Source projects, as do the other Linux distributions
  
• Fedora is used on client side applications, as well as for server side usage and deploymeents
  
• Self Immunization (in case of Viruses) is a whole different thing, and I don't see if a general Liux distribution does that. It just restricts the virus from self replicating to other locations (due to permission and lack of support for Windows PE Executables).

On the other note, I would like to request to adhere to common communication etiquette and Mailing List guidelines. As for e xample, please don't post a message with a generic subject like "Question" as it is unable to predict what the email contains. Also please do not deviate from the context of the originator thread; for other question/queries/discussion/suggestion/... send it in a different email thread. This helps maintain a healthy Mailing List and encourage communication.

Again, this is not to discourage you all from using this mailing list for FOSS related (and sometimes off-topic) issues, but it's a hard job for ML maintainers to make it an aspiring communication platform for all FOSSians. As always, expecting help, cooperation and suggestions from you all.

Thank You.

Ahh. Virus, Malware and MS Windows. A perfect combination. Haha.
Not every OS is free from them to be honest; and majority of linux
users probably know
about these already so nothing substantial in my post.

Every now and then a new user of Linux comes along and says "now I am
virus free cool! because I use Linux :-)". No.
Sorry bud, but that's not entirely true but rest assured, you are
indeed using a modern kernel and a great OS ;)

You can try these at minimum:
- harden and keep your kernel patched and software up-to date
- learn about software security updates, infection vectors and why they matter
- don't click random links on the interweb and use general common sense.
- .....

I see that FossNepal has become a huge list now! :-)
Good stuff.
Later
