Fedora Security :: Curing Windows Via 12 Partition?
Jun 1, 2011
My windows 7 system is severely infected and I can't cure it from within itself or safe mode.I was going to do that with ClamAV but as I am running F12 the current version is not supported. Do you know an AV client that you could recommend for that purpose.I don't want to risk upgrading F12 as I don't want to jeopardise my only stable system at the moment.

During a recent install I made the leap to encryption,but /boot must remain unencrypted.Is there really any legitimate security risk to having an unencrypted /boot partition? I mean basically someone can just see what kernel you're running which they could see during boot anyways right? Oh I and keep all my financial documents in /boot/finances/ (haha ok not really, but I am serious about the first part).

I'm dual booting 10.04 with windows 7 and it occurs to me that I could scan the windows partition for viruses FROM linux. Is anybody doing this sort of thing? Does that make any sense?

Is it possible to remotely access, inject, manipulate files and/or folders in the Windows NTFS partition when logged into Ubuntu?
I'm either logged into Windows or Ubuntu but NOT both -- ever. Therefore, while logged into Ubuntu, would it be possible for someone to crack into Windows via Ubuntu using Wi-Fi or modem?

My windows partition is infected and I recall that it is supposed to be possible from the linux partition with ClamAV. Now I'm running Fedora12 but this forum is much more active and I suppose that doesn't make a big difference. I tried to find something on google but most procedures seem to involve a Live CD but it would be more convenient for me to just do it from my linux distro running. Is there anything I have to be aware of or is it literally just scanning the windows partition with ClamAV?

Let's say I have an avi file that contains a virus for ntfs windows xp sp3. I put that file on a linux ext3 partition. Then on a windows xp sp3 nfts computer, I connect to the partition over a network share via smb. I run the file within the share so the file is never physically on the windows xp sp3 computer. In this situation will the virus infect the windows xp ntfs partition?

My Windows XP Pro laptop has been attacked! Windows will no longer update and Microsoft Security Essentials will not update either. I've been trying to resolve the issue for over two weeks with Microsoft support, but it's just taking too long. I also tried some rescue CD options (all running some form of Linux, obviously):
- BitDefender Rescue CD (removed infections, now detects nothing),
- Kaspersky Rescue CD 10 (removed infections, now detects nothing),
- Trinity Rescue CD (won't load AV Engine, so can't use it to do anything).
Malwarebytes cleaned a bunch of stuff, but will not clean the final threat detected (it's supposed to get deleted on reboot, but never does). Hijack.FolderOptions is stuck in the accursed registry, and it keeps causing Windows Explorer to crash. I cannot rename files or work with them or everything just crashes.
So I'm ready to reinstall XP from scratch, and add a dual boot with Xubuntu & LXDE, which I'm already running on a much older laptop.
Question: I want to rescue the files I need. My idea was:
1) Install Xubuntu with dual boot.
2) Copy over files from Windows XP partition using Xubuntu.
3) Back up files to an external drive using Xubuntu.
4) Reinstall XP Pro and format hard drive.
5) Reinstall Xubuntu with dual boot.
6) Use Xubuntu for daily use.
7) Only use XP for those tasks that require it (TomTom updates ...)
Should I be concerned about the security risk from copying files from the Windows partition to the Xubuntu partition, and from there onto an external hard drive?
Is this the way to do it, or is there a better way? I just want my laptop back in working order. Right now I can't use it for anything.

Some time back using this computer a SucKit rootkit was found. Having dd urandomed the drive, flattened CMOS battery, flashed BIOS, run Knoppix live CD 6.1,using no flat pack battery (laptop), and memtested the RAM, I am still having problems with what I suspect is a javascript file that tries to reload the rootkit from? firmware. I suspect the firmware as everything else should have eradicated it??
Also it or a hacker via a backdoor then corrupts the drivers so devices malfunction. Windows security programs and rootkit detectors don't seem to pick it up. Fresh install of Windows or linux after the above still show this problem, though internet not used. The person who admitted rootkitting this machine is capable of writing java programs or using javascripts to do all this.
When viewed using Ubuntu 8.4 files and dates on a Windows partition appear normal both in file manager and terminal. However booting using Knoppix CD these files are all green, and I cannot change their permissions, even as root. ie: everything is green including text files etc. If I copy them to a linux partition, I can change their permissions and make them nonexecutable and nonwritable. Also on the Windows FAT32 partition the . directory has the date 1 Jan 1970.
If I disable any green files, I can shutdown and reboot cleanly. If I don't I start having problems shutting down [/usr/sbin/init ?] And always these follow a pattern:
Can't remember details as I have now corralled the beast but error messages relating to:
nfs-server
inet.d/statd
are the start of these.

Now however its not letting me resize the Windows partition, mounted or unmounted. It currently occupies the whole disk. I would rather not reinstall the whole thing over again, but I will if I have to. Isnt there an easy way to shrink a Windows partition? I swear Ive done this before and it wasnt this hard. Could it be a problem with the Mint installer that now asks me if I want to unmount my disks before it goes into install mode? On this PC I would like to have
Windows XP
Mint
Ubuntu-Studio
Edubuntu
One of the E17 OSs
Puppy Linux (to create a remix)
I am probably going to put most of the linux partitions on the second laptop drive but I want to install files on a non WIndows NTFS partition.

I got tired of dual booting on my old computer so on the new computer I am planning to run XP on VMware Player. The problem is that on the new computer neither Ubuntu or XP can "see" the FAT32 partition. I intend to use the FAT32 partition for photo images and old Windows files and need access from both Ubintu and XP.
Partition table entries are not in disk order.

I'm planning a fresh F13 install, with separate partitions for /boot, /home, /tmp, /, and swap. All but /boot will be logical volumes, and I'd like to encrypt all but boot. If I encrypt the underlying partitions, is there any reason to also encrypt the logical volumes themselves?
my system will be:
HP dv6-3040us Pavillion laptop
AMD Phenon II
4GB DDR3

Anyone had any experience with unlocking a LUKS encrypted root partition via ssh? It is ok to leave /boot unencrypted.
There are a few pages from google with the debians variants, archived by putting dropbear into initrd.
I like to do that with my fedora/centos remote servers, but struggle to find any resources specific to it. Anyone has any suggestions and thoughts as to what might be a suitable way forward?

I would like to encrypt my swap partition ...During installation, I tried to select the "encrypt partition" choice, but it needed a passphrase.After installation, I tried to encrypt my partition ... I followed this article: The problem is that my swap partition always changes its path ...When I first booted the system, it was /dev/sda10, next it became /dev/sdc10, now it is /dev/sdb10. This is probably the reason why in fstab all entries are according to UUID.However, the swap partition is not fond of UUIDs ! I tried to mkswap /dev/<current swap partition> -L Swap, I received a UUID, puted it in /etc/crypttab ... it worked for the first time ... but the second time... did not.

I have C: and D: on my computer. the D drive has 250 GB of free space. I would like to install it on the D drive without harming my existing windows. I have booted through an USB and it has an icon that says "install fedora on your hard disk". How do I make sure that it will be installed only my D drive without harming my windows?

I have a dual boot at home with W7 F15. The Fedora drive is encrypted because that's where all my important stuff is. On the rare occasion that I do boot into Windows, I wondered if there would be any way of accessing my encrypted Fedora drive? Is it possible to decrypt and mount from Windows?

does anyone know the best way to encrypt an entire HD with both Fedora and Windows 7 on it already? At the very least I would want to encrypt the Linux partition, as that has the most sensitive stuff on it.

I need a FREE solution that can image an entire Luks system encrypted volume and the rest of the used HDD, the MBR and /boot partition. Note: MBR and /boot are not encrypted. Note 2: I want to be able to restore entire drive from image with only a couple of steps. Note 3: Destination HDD space is a factor. Image file must be compressed and the image file must be around 40 to 50 GB or less. The smaller the image the better.
I have used clonezilla live cd before but not for encrypted volumes. I know you can install it in Linux. But, I don't know how to configure it after installation. I would be very happy if someone could tell me how to configure clonezilla in Fedora. How to guides are also welcome. I have one more question. If I image the encrypted volumes and all the stuff I mentioned above while logged in to Fedora, and I restore the drive from the image, will the recovered drive still be encrypted?

I got an acer aspire 4310 with vista pre installed.
I installed fedora 10 on the D:/ drive by setting the D:// drive as free space within vista and then installed fedora 10. So now I have dual boot vista and fedora using grub.
How can I delete vista and install Fedora 12 on that C:// partition and be able to keep and boot my fedora 10.
Has anyone here done this before?

I'm trying to view my files in my windows XP partition and I tried the following with no success:
1. updated /etc/fstab to include the following line:
/dev/sda1 /mnt/win ntfs-3g defaults 0 0
2. tried this command to mount sda1:
mount -t ntfs-3g /dev/sda1 /mnt/win (got an error message saying no such file or directory)
Here's what Fdisk shows:
Device Boot Start End Blocks Id System
/dev/sda1 * 581 8924 67023180 7 HPFS/NTFS
/dev/sda2 1 580 4658818+ b W95 FAT32
/dev/sda3 8925 8988 512000 83 Linux
/dev/sda4 8988 19458 84096000 5 Extended
/dev/sda5 8988 19458 84094976 8e Linux LVM
Since I'm pretty green at Linux, this is all I know how to do (for now). Isn't there a way for Fedora to auto mount these devices when it boots up?

I have upgraded my F8 installation to F10 installation recently. After this upgrade, I am able to access the windows partition, and add remove files in the same.Today, I tried booting into my windows partition and I was unable to boot into it. My laptop tried to boot into it, but crashed and came back to the grub selection screen...I did not have this issue previously, with other Linux installations..

I have a dual-boot system, Windows XP on primary HDD and Fedora on Slave HDD. NTFS -3G is installed in Fedora, but I would like to hide (or not mount) Windows system partition on Fedora boot, as I have multiple users in Fedora and do not want them to access this partition. I do want to mount/display my NTFS D: partition in Fedora. Is there a way to exclude an NTFS partition from mounting by default?
