I just wonder is it really necessary to have a antivirus software cos almost 99% virus cannot attack a Linux but there are still some Linux virues out there.If you think it is necessary,which free antivirus software which you will recommend for Redhat v9?
Yes I feel it is still very necessary if you are on the Internet period. That 1% will destroy everthing!!!!
These are all good and available at Freshmeat.net
Kaspersky
DansGuardian.
Sophos
Actually many peaple "think" that virii can't harm their PCs if they have a *nix box. The fact is virii can harm numerous OS styles... its just that it wouldn't hardly popup at the startup without the help of a rootkit unlike alot of these windows trojans/worms.
So whats the difference between the two? Well alot of windows virii sets up a .reg or whatever so it'll load at the startup but if something is on a *nix then a attack would come almost instantly when you open the file or it'll probably distort your OS like a rootkit would in order to setup attacks on a later date instead of instant yet small attacks. You must also remember: 'if you have dual boot and you install virii... once you switch OS you can be effected.'
If you don't feel like geting AV then I would highly suggest consintrating more on firewalls especially since exploits are more common then *nix virii.
Besides, it can't hurt. Worst case scenario, you install it and it never gets used. Small price to pay for knowing that your computer is as safe as you can make it.
And, if you have a virus scanner, then you won't accidentally pass on a virus by sending an infected file to a friend. Just because it doesn't hurt you computer doesn't mean that your friend won't get pissed off because the file you gave him killed his computer.
My computer had a copy of some virus sitting around because a friends machine was connected to it via SMB and it wrote itself to my shared folder..., it didn't hurt me any, but had another friend double clicked on that file...
Think of it as kind of pre-emptive quarantine, if you know that no file on your box is infected, then you don't have to worry about accidently infecting another box.

Which free Antivirus software will you recommend since Linux will still get infested with viruses?I have used tone of difference antivirus softwares for window OS but need your advise on Linux.
perhaps it can help you :

Hummmmm....... why did this thread become such a hotspot for negs?
Hmm, why worry about it?Quote:

What in the WORLD did you just say? It made no sense at all. There are *NIX virii, but very few are out there. Rootkits/trojans/virii/worms are totally different things. It seems you are trying to lump them together. Here is such worm http://www.linuxsecurity.com/article...icle-2330.html I think not runnig a *NIX with out of the box installation will prevent a lot of problems including not running as root, getting patches, not using vulerable services and tightening the ones you do use. That will also reduce the number of canned sploits and rootkits that are out there if you have good admin sense. Heh, laziness (I am guilty) is the biggest sploit of all.Quote:

As for Windows, there is not a whole lot one can do except run good AV software. And yes. AV is a gooooood thing :D
Your forgeting the payloaded tools/attacks rootkits have. These payloads usually make it so the owner has control over a zombie, can launch dDoS, then if the owner of the rootkit gets bored he/she can destroy the zombie or other PCs. Your forgeting that Rootkits/trojans/virii/worms can all have destructive payloads and can share each others' characteristics... oh and excuse me but all of these things to me puts them straight into the "dangeous yet could be detected with a good AV/FW/patches/administation" catagory. And just like me... a good AV that is well updated sees them all as a threat....
Now im going to go have a drink.....
Oh... and P.S. thank you for your time, bad additude, mis-understanding, and negs.
Good night...
"I just wonder is it really necessary to have a antivirus

Be careful verify the checksums of rpms and tarball files
on mirrors or any websight if you want to avoid the risk
of installing a trojan horse this include rpm kernels,
specific libararies. If you don't know the source don't
take chances!

OMG
I guess I am just a noobie... cause I REALLY NEED A TRANSLATOR. I have no idea what most of these posts even say. I think people just heard a few buzz words and used them.
1> a windows specific virus will NOT AFFECT LINUX. It is NOT POSSIBLE.
2> an good AV program will detect standard distrabuiton of virii, worms, trojans, and rootkits, BUT they will not detect them if they have been packaged properly (this goes for any OS, not just nix).
3> a firewall is NOT the solve all of security, they are possible to be bypassed (see firewalking)
YES install a virus scanner if you are online. One of the first posts was a list of free AV programs for nix.... pick one and install it. Also, if you want to be safe, make sure you install a firewall, keep your system updated, and run something like chkrootkit (I believe that was the name) on occassion to make sure that nothing has bypassed your AV program.
And people, unless you have something to add to this ( I may be forgetting something) and YOU KNOW WHAT YOU ARE TALKING ABOUT, let this thread go.
will you have my babies soulman?
only if they are cooked for lunch
was thinking dinner but whatever suits you is fine for me
I figured we would cook up some of the people in this thread for dinner, but then some of them are not even suitable to feed the dogs...
"1> a windows specific virus will NOT AFFECT LINUX. It is NOT POSSIBLE." As I mentioned on my first post on this thread.... if you have dual boot you probably won't be effected in a linux enviroment but once you switch OS you can be effected by the installed VIRII... And just because it can't infect the files of multi-platforms doesn't mean something couldn't dDoS other platforms.
2> Who changed the edit post time limits? Im stumbling around half asleep while peck typeing... then next thing I know everyone hates the drunken redneck who can't spell or put together sentinces. "me".
"3> Also, if you want to be safe, make sure you install a firewall, keep your system updated, and run something like chkrootkit (I believe that was the name)....

Ohhhh god.... I hope this doesn't spawn into a "go with or without FW?" thread....
Bark! Bark!
Will you please explain to me how a microsoft virus gets installed in linux? I would really like to hear this one....Quote:

and you were just saying you didn't want this to become a firewall thread, yet that is how you stop a ddos (although unless you have very high speed connection, you will probably have to contact your upline provider to stop one)Quote:
And just because it can't infect the files of multi-platforms doesn't mean something couldn't dDoS other platforms.
Did I specificly say install through linux? NO! As I was mentioning: If some guy downloads something that appears as "a cool game" he is more then likely to switch to windows to play around with it but he/she ends up seting up a attack on the system.... and as long as its in the windows enviroment it'll keep going.
Oh and.. actually I was refering to dDoS utlilities that could be planted into a sys. and how they could still do dDoS attacks on other platforms which BTW the dDoS tools can sometimes be detected with !!!"AV"!!! But yeah... if your on the other side of the attack beleave it or not being noisy over the phone while calling the ISP or look very threatening in the offices of your ISP might force them to do something :) after all... "a firewall is NOT the solve all of security, they are possible to be bypassed (see firewalking)"
As far as i am concern,security is based on antivirus software and firewall.They both play an important roles in maintaining a good security.For window,if you wanna stop a DDOS attack and you use a good firewall which able to drop the flooding packets instead of blocking it.If your firewall tend to block it,then i would say that this firewall is no good cos your system will slow down from the flood keep coming through.When your firewall is able to drop the packet,the flood is almost has no effect on your system at all.
What I'd say to that question is this, regardless of there being less viruses and worms for linux, you may still want to run an anti virus on your linux box, because you might be running a server, Mail for example, now, would you like some stupid vb script messing with the users you serve? If your not running any server on linux, then I'd say it's not necessary as long as you don't run any executable files from unknown sources.
PuRe
yes thats really necessary coz someday linux can attacked by virus coz for me everything is possible :)
There are no virii on your hard drive, nor can the infidels put a virus on your hard drive. The virus was created by the dogs of the west and will never defeat the proud equipment on your desk. I call on all the strong hard drives to rise up and beat back the infidel virii and declare jihaad on the worms of the dogs.
There is no such thing as linux, it does not exist. It is a falsehood that was created by the monopolistic capitalist dogs of the west to steal the peoples oil.
The only wall of fire you need to worry about is the wall of fire that will accompany our proud army as it continues to roll to victory over the infidels. They are dogs, and I spit upon them, I beat them with the sole of my shoe.
Tisk* tisk*.... How dare you!!! You could have atleast changed the changed OS names and replaced it with a MicroSoft OS in the part where you said: "There is no such thing as linux, it does not exist.

Bill G. is the real evil/greedy one.... attack him instead.
Even I a Winblows XP user would rather see a attack on M$ instead of Linux. I may not be overly fond of Linux, but there are worse things out there.Quote:

Microsoft is really lousy cos too many flaws found on their OS,especially the buffer overflow.I have been using Window OS for more than 20 years and i still find Linux is still the best OS out in the market.Microsoft Window OS is so prone to DDOS,therefore i do not like it at all cos you will realise the vulernability when someone try to find exploits on your system.Window also cannot stop or drop the packets if someone try prone your ports or doing all sorts of flood attacks such as Land attack,Smurf attack,Spoof flood attack,etc.If you look around,those hardware firewalls are using Linux base firewall to protect your system.Quote:

Umm a fire wall wont stop a DDOS from doing its thing, and Linux is just as vulenerable as Windows..if some one decides to DDOS you all you can do is rotate your IP or get your ISP to block the attack vectors.. As for the attackes you mentioned they where all aimed at the *nix world origionaly, sure windows is suseptable (if un pached) but so is *nix(if unpatched). Windows has a lot of problems (resource hog, security issues, ect) so dose every operating system..If you want somehting secure go to system 7 or OS2/warp :)Quote:

Who tell you that a firewall will not stop a DDOS.If you talk about DDOS attacks,you can filter all these very easy with a good hardware appliance(hardware firewall) or using a good software firewall being able to drop the flood packets instead of blocking it.You do not need to turn to your ISP for help instead you can solve it by yourself.I got average of 200 DDOS a day and i solve it myself without affecting my system perform.Quote:

I do agree with you that unpatch Window OS or Linux are prone to DDOS.Therefore it is very important to get up to date your patches for Window or Linux.It is important to get a firewall to secure it.Quote:

I don't care if you block the packets or drop the packets, your bandwidth is still shot to hell. So what if your mahine keeps running if you can't get anywhere and no one can get to you. For some reason I doubt that you get hit by 200 DDOS attacks a day. Do you even know what DDOS stands for?Quote:

Distributed Denial of Service = DDOSQuote:

Your Bandwidth will only shot to crazy if your firewall is blocking it instead of filter(dropping) the packet.WHo tell you that i cannot get anywhere and nobody can get to me?That seem to be no reason why i can go or surfing my internet with ease with all those floods.Therefore i guess you better read more about firewall before making this comment.I run a game server,my server is often attacks by script kiddies and my firewalls is able to filter it.If my firewall can filter it,i see no reason why other Linux distro cannot do it too.

If you keep complaining to your ISP,what they did is most likely to block that IP.In fact,you can block it by yourself.
better to be prepared for the worst.better opt for an antivirus.atleast we have something to blame for a sys crash
sorry this coment was not meant for this post, pls excuse, am sorry
heh its always good. Ive had the experience of getting the VBSloveletter about a year ago when it first came out or something.. and it didnt affect my machine hence the vbs, and sent it to my teacher! :P but i didnt know it had that virus in it, it was around 9-11 and was a funny picture of a dude riding a carpet or something
