i was thinking that is there a way to check data flow for viruses? i mean if i set up calm av in my internet sharing server could it detect anything in incoming and outgoing data ?!!

I use Firefox 3.5.9 and Ubuntu 9.10.
There is a suspicious amount of data (more than a megabyte) being uploaded from my computer whenever I log onto a commercial web site on which I advertise rental properties.
Is there any way I can see the data being uploaded - I am pretty familiar with the Unix/Linux system and commands.
Is anyone aware of a detailed "flow chart" -- arrows and decision diamonds, etc -- that describes the file access and permissions processing? I would love to see that diagram. Years ago on a platform far away (Digitial VAX/VMS) their manuals had such a flow chart that covered not only the user-group-owner and read-write-execute permissions decision making but also include "access control list" processing at a superficial level. If someone has access to the VAX/VMS flow chart, that might be a start toward sorting what linux does.

folder1 ----> folder2 and many other files and folders
folder1 has a condivision access read and write for everyone so I get no problems with passwords for all those who have access but i use ntfs security to do it read only (viruses act like if a pendrive is connected and mainly put infected files just in the "root" of it, in my case in folder 1) and then give everyone full control in folder2. I've been trying to understand how to do this but I'm quite new to linux and smb.conf really scared me. I've tried samba graphical tool which was a lot easier but I'm not able to achieve this kind of result: no need of user password for users to mount the share and no write possibilities in folder 1 and full control in folder 2.
I am a very new Linux user. My first OS is Fedora 12, which I just recently installed into my laptop. So far, I am thoroughly enjoying it. I do have a question bugging my mind though. Linux systems are known to be very safe from viruses, mainly due to programmers targeting the Windows platform. In Windows, common methods for virus infections are from infected executable files, external drives autorun... ETC.
Now my question is how do viruses spread into a Linux system? And with so few viruses known to exist for Linux systems, do I really need to be aware and take precautions for viruses (For example in Windows, disabling autorun function for external drives)?
I read some articles about viruses in Linux and about some antiviruses which work in Linux and delete Windows viruses but I still don't understand: is there any antivirus which specializes in Linux viruses? Even though there are very little of Linux viruses, I know.
View 11 Replies View RelatedI have a dual boot computer. The WindowsXP "side" has been infected with a rootkit virus. So far UBUNTU has not been affected to my knowledge. I have not yet been able to remove the virus from the WindowsXP "side". I am thinking of deleting the NTFS partition and have the computer fully dedicated to UBUNTU.
Now for my question. Is there a possibility that the virus resides in the MBR and that I need to "rebuild" the MBR to actually remove the virus? Even more extreme, should I totally re-install UBUNTU in the name of safety and precaution.
I would like to use my Ubuntu 9.10 Karmic system to scan and clean viruses from Windows based HDD. I have KlamAV, AVG, and AVAST. I couldn't get F-prot to work. I don't find a debian package of it and don't know how to install tar.gz and the tutorials don't help a lot. Are there other antivirus solutions which are good for cleaning Windows OS but work on Linux/WINE? I wonder if I can install antivirus software in WINE and scan with no problem the hard disks.
View 5 Replies View RelatedI have been told that some virus scanners for linux (including but not limited to AVG, Antivira, clamAV, others) are available to ubuntu. My question is which of these still CURRENTLY support detection of WINDOWS viruses in addition to linux viruses. I would like to boot the Ubuntu live jump drive I have to scan windows machines and at least detect viruses, dont really need to repair. who knows which virus scanners compatible with ubuntu that will detect windows viruses as well
View 3 Replies View RelatedI have set up a virtual machine under VMware Player 3.1.2 in Debian. Operating system of this virtual machine is a Windows Server 2003. I would like to periodically test this Windows Server 2003 installation for viruses. Obvious solution would be to install an AV software under this Windows Server 2003 installation. However, I was wondering, is this possible to use NOD32 for Linux or clamav in order to test this Windows Server 2003 installation for viruses? Is NOD32 for Linux able to detect viruses inside the .vmdk file?

I'm going to be needing to copy over 2 terabytes from one drive to another in a couple of days and I need something that I can use to transfer the files with CRC checking. Something comparable to Teracopy in Windows.
Open Source is an absolute must. I'm running on Debian and getting away from Windows to get away from all of the proprietary software. If it's going to be proprietary I might aswell just boot back into Windows as far as I'm concerned.
Some of the features that would be nice but not needed
-GUI (preferably gtk)
-Pause/Resume (it's going to be a long transfer so it would be nice.)
Those would be nice but CRC checking is an absolute must have for so much data.
I want to have brasero or k3b do a data check after burning a backup cd. I know that in Nero for Windows you just click on the box that says "verify after burning". For brasero I see that you need an md5 file but it will be to tedious to use an md5 utility to make a checksum for every file and then put in in a txt.

having a slow internet connection, I bought the all maverick repository on DVDs, copied the files on a usb drive and modified the apt sources file to consider the local repository only:
Code:

Even though I am reasonably sure it is safe, this local repository is not authenticated and I can only install package through the command line or synaptic, the Ubuntu Software Centre giving an error message "Requires installation of untrusted packages"...I thus would like to disable the apt authentication check for this local repository.

Two processes are communicating through a pipe: A | B. A is writing data faster than B is reading it in. Is there any way to have A limit its writing rate to match B's reading rate?
AFAIK the pipe will get full, and will make A's writing block, waiting for B to read in more data. But is there a way to limit A's writing rate before the pipe fills up? (In a way it's like having a pipe with a really small capacity, but as far as I know pipe capacity is a constant compiled into the kernel.)
Code:
EXAMPLE FOR CLARIFICATION
Right now the command is printing out the following in 1-second intervals:
But with flow control it should print out (again in 1-second intervals):
...since "date" would block on the writing loop due to the slow reading loop.
