I need to know whether Ubuntu can be hacked when it is installed as a dual boot with W7 by hacking windows and getting access to the Ubuntu partition?
What I would also like to know if this way can be used to put a key logger or screen capture in Ubuntu which installs next time Ubuntu is started?
I built this computer with a Gigabyte motherboard, i3 processor, 8Gb ram, 64Gb SSD, and 1.5Tb HDD. Loaded Windows 7 to the SSD... repartitioned the drives and loaded Ubuntu 11.04.The start menu comes up to select Windows 7 or Ubuntu... when I select Ubuntu I get a screen which reads:Windows failed to start. A recent hardware or software change might be the cause. To Fix the problem:1. Insert your windows installation disc and restart your computer.2. Choose your language settings, and the click "Next"3. Click "Repair your computer."if you do not have this disc, contact your sys admin or manufacturer for assistance. File: ubuntuwinbootwubildr.mbrStatus: 0xc0000098Info: The selected entry could not be loaded because the application is missing or corrupt.
This screen continues to come up. I tried to load Ubuntu with Wubi but it would not install... I have now installed it from a DVD but the load screen keeps putting me back to the screen above. I can't load from the Windows CD it won't recognize it even if I change the bios setting.Windows 7 seems to be running fine... and Ubuntu seems to have loaded fine... so how can I get my Windows boot screen to go and load Ubuntu as my OS?
Finally made the switch over to ubuntu, but I needed to keep my windows7 for several reasons. Let just start by saying I have two hard drives, a 200gig(which holds my windows7 partition) and a 500gig(has a 100gig partition which has ubuntu on it). After finally getting 10.04 to install on the 100gig partition and everything running right, I tried to load up windows7 and got an error.
Something along to lines of "the partition does not exist". I believe I messed up on the last step on the install, as I might of just been careless. I remember reading somewhere that if using multiple hard drives grub may get messed up in one way or another. IS there a way to fix this and make grub realize that window7 is on another partition, or am I out of luck?edit: Id like to add that grub is recognizing windows7, it just will not load off the other partition(I think)
I have done some commands in ubuntu 11.04 and got problems, thinking of reinstall it. (laptop acer 5738zg)
Previously when i have dual booted win7 and ubuntu10 and linux mint i always get "grub rescue" when i try reinstall my linux partition, and it ends with i have to do clean reinstall of both windows and linux, which is a major pain in the rectum area
Is there a way to make my linux go back to original state without reinstall, and if i reinstall, how can I do this without loosing win7 partition and get this awful grub rescue message.
I have a laptop that has a dual boot of Windows7/Ubuntu10.04. Ubuntu loads fine, but Windows 7 does not. It shows up in the Grub, but it will not load. I assume that the boot loader was messed up somehow, but I am not experienced at deciphering the boot info file. I was hoping someone might be able to take a look at the file and tell me what the issue might be, and also which part of the text indicates the problemBoot File:

Windows 7 is first boot disk. Installed Fedora 13 on second disk from DVD. During installation it did not ask if I wanted dual boot. Fedora installed fine on second disk. Rebooted and only Windows will lood. How to setup to dual boot? Can I modify Windows Boot file? or do I have to install Grub on to sda. How do I do that?

If once i boot into windows 7 and restart the system i am loosing boot menu options.The following error i am getting"no module name found Aborted.Press any key to exit".If i press any key,I guess its trying boot using internet and lastly it says Operating system not found and hangs.

I use a dual-boot setup with Windows7 installed in parallel to Fedora 15-x64. Whenever I had Windows in use and jjust reboot the system into Fedora, the NIC does not work as expected. Instead it goes in an endless "em1: link up" loop which results in very low bandwith or even complete network timeouts. This happens in Firefox as well as with yum or ping.

If I directly cold boot into Fedora (after the power cord has been removed and the system got completely re-initialized) there are no problems at alll and I get a fast and stable network conection. This also happens with other linux distributions, for example SysRescCD.
Hi,I had a Windows 7 installation and I decided to install ubuntu 11.04 I tried several times but every time soon or later something with grub goes wrong.Most times I get the error "no such partition",once it just halted after "verifying DMI ... " .I fixed windows mbr with "bootsect /nt60 C:" and then tried to reinstall grub with boot-repair .It showed no errors but after reboot I get "no such partition" again.
My scheme is something like :
/dev/sda1 -> the windows 7 system partition NTFS
/dev/sda2 -> partition for windows programs etc NTFS
/dev/sda3 -> partition for files(images/music/videos) NTFS
/dev/sda4 -> extended partition

I want to know if any one hacked or getting into my computer. I am using lucidlynx right now, My computer directly connected to modem, not using any wireless router. How can i check if some one hacked? How to prevent it?

So now I use it as a glorified DVD player. Then, around February the hard drive died. I put it in fresh, loaded a couple of regular games and the DVD modifications to play DVD's. So, besides the basic upgrade to 9.1 not much as been done.
Well, last week my panel disappeared. I procrastinated and last night I got on the computer. I did F2 and "xfce-panel" and my panel reappeared exactly how I'd last tweaked it.
With on exception. This blue globe, "Akonadi" had mysteriously appeared.
Thing is that I haven't installed or updated anything for 8 months...why? becuase I haven't had this thing connected to the Internet. The wireless tower has been on. (my bad) but all of the signigals in my neck of the wood are encripted so I just let it be.
I don't know where this program came from. Is it loaded in xubuntu? Why would it show up? And furthermore if there was someone with malicious intent (unfortunatly I do have to take that into consideration) have put this on for data collection?
I have windows computer and it is being hacked.About month ago or more some one hacked my router and install new firmware from Firmware Version: Talisman/Basic V1.2.9a
My router is linksys and SSID got changed to sveasoft.I had WPA set up and MAC filtering .
Some one hacked my router and change Firmware Version.And user name and password also got change to just admin.

Has anyone hacked/installed Ubuntu on the Nokia N900 and/or Android phone? MeeGo is coming very close to a full desktop distro. I am very curious to see what sort of performance Ubuntu (or something lighter like Lubuntu) exhibits on a mobile device.
View 3 Replies View RelatedI had a serious breach of the cellular segment of my communications network this week. All I can say is nobody got hurt. The attackers also knew where to find me via email. I'm concerned that perhaps they've penetrated this aspect of my system as well, although they seemed pretty specifically focused on the phone. There have been no changes on anything on my computer, and of course, I went ahead and changed all the passwords. How can I verify or at least look into the possibility of having been hacked as well.
View 8 Replies View Relatedmy computer has been surely hacked for at least more than two months; my private information are being hacked and spread around! I initally used Windows Vista and I had the firewall off and no antivirus software. When I realized that my OS had been hacked, I began turning my firewall on and installing security softwares, but nothing stopped the hack.
Yesterday, I erased all my partitions and installed Ubuntu 10.10. I installed rkhunter and a firewall. I changed my static IP adress, at least for the sake of knowledge, to another one, then I got disconnected since my router only allows my old IP.
When I'm about to write my admin password, I disconnect from the network. I've scanned my system using rkhunter, and the result is a list of 30 suspicious files!
Can I adjust my router in a way that it can allow any IP adress? If yes, can I have a non-static IP adress? How to prevent the hacking in the first place? However, I believe, I don't know yet, that my Ubuntu has also been hacked...
If I can't get rid of the hacker(s), then I should permanently disconnect from internet and find another way to receive information anonymously through the internet.

Everything was fine for years but a week ago my server got hacked.I don't know how the hacker got my username/password - it was not something like admin, password.9 months ago my PC was infected with some virus which connected to the FTP server by using password which was saved in CuteFTP and infected all index files with some javascript. Then I changed the user/FTP password and didn't save it anymore in Cute FTP. Of course, I checked all the folders and re-uploaded all infected files. Is it possible that this virus uploaded some hidden file which was able to get the new password for this account?
The server was hacked from so called Tor IP address. I am tiref of worrying about server security and now have an idea to get a static IP address from my ISP and to allow logins only from this IP address. What do you think about it? This idea looks good for me but are there any risks to lose access to the server. Can ISP provider change the static IP address for some reason?
I believe it is a keylogger because my Facebook account has been hacked, I believe my email has as well. I heard that even if you reformat a harddrive, the virus could still sit there and apparently that is what happened to me. how to be rid of it and keep my security. I installed RKhunter and Chkrootkit. Rkhunter reports warning files while checking my filesystem. I can post a log if need be.
View 9 Replies View RelatedMy server (Ubuntu 10.04 desktop) was hacked. I had my ethernet plugged in to an Intel 82557 Ethernet Pro card (Pulse) when my server was first attacked. After it was attacked I reinstalled the system but my ethernet card still would not work. Ubuntu recognized it, but it is continually disconnected and the little status lights on the card do not light up anymore.
So then I plugged the ethernet to the mother board itself. Well, my server was hacked again and now the ethernet on the motherboard does not work. Again, Ubuntu (after a reinstall) recognizes the hardware but nothing happens when I plug the etherent in. The motherboard is a BioStar P4M900 VIA chipset. I have a few of the system logs here [URL] which I saved right after the first attack.
I have a Asus EEE PC 1005HA netbook, which I use with Windows 7. I've been abroad for the last 2 weeks, and when I came back I found out my younger brother has installed Ubuntu on it.
When I asked him he told me it's no problem, and he didn't overwrite Windows, just installed on another partition.
However, I'm trying to get back to my original operating system and I have no idea how. Obviously, he has none either as he is just an impulsive 15 year old.
I'd like to either uninstall ubuntu and return to my windows OS, or just choose at boot time which OS I want to access (I don't really mind having a linux onboard, I assume it has it's merits).
I'm trying to take my current windows7 (x64) setup and make it into a dual-boot setup with slackware 13.0 (x32) and am hitting a brickwall. I guess I would like to know if I can salvage the situation without formating my windows drive. I fully intend to, but I had hoped to not do it this month. I'd like to get dual boot going so I can master it and acquire all the files/drivers I'll want and then format and do it 100% right next time.
Currently I have windows setup on a 3x 500gb Raid0 onboard array which itself has been flawless. After I shrunk my current partition size to give me about 25gb of free space I proceeded to setup Linux, and I was unable to perform the cfdisk portion for partitioning the array for Linux.
I tried using cfdisk:
/dev/hdx (a1-a3,b1-b3)
/dev/sdx (a1-a3,b1-b3)
I even attempted to locate with: cat proc/partition and tried using cfdisk on every device it located. It always said it was either an unknown partition table and should I start at zero, or bad partition. I was of course too concerned over my windows setup (which has almost 1tb of stuff I have not backed up) to go any further into the unknown.
PS: I have used Slackware before, back at 8.1, 10, and even a very brief interlude at 12.0, this is my first attempt on this computer however with 13.0, it is currently running fine on my laptop and my PS3 (Laptop is even dual booting 7/Slack13. Albeit without raid)

I installed 10.04 and Grub won't boot into Windows7. I attempted to fix the problem through several different methods and nothing worked and I fear I made the booting problem worse than it was to begin with. I can boot into Ubuntu just fine, just not Windows7. Black screen with a cursor upper left hand. Windows7 repair disk does not help and using Windows7 command line repairs did nothing.
So here is an idea I came up with: Is there any way I can back up the Windows partition exactly the way it is, reinstall Windows7, and then somehow lay down all that information directly over the install to make it exactly like it was?
I doubt it is that simple, but is that possible? Like basically unhiding all the hidden files, copying them into a folder on my Ubuntu installation, reinstalling Windows7 and just copying them all back?
I just got control over a server that was hacked several months back. The other day we started receiving rejected emails sent from my server to a yahoo email address that is no longer active that contained users login information. I am trying to find the process that is sending these emails. So far its been like finding a needle in a haystack. The email that is being sent is appending the login information each time it is sent so there must be a local file that contains this information. I have tried using grep and find without any luck.

View 7 Replies View RelatedBefore the installation, I had triple boot of WinXP, Win 7, Ubuntu 10.10. As you can guess, the main boot-loader was grub. The second is Win 7 boot loader, and there it gives the option what to choose, load XP or Win 7.I made a decision to remove Ubuntu and install Debian(you know better than me why I did). So first, I searched a guide how to un-dual-boot. It told me to delete the two partition that Ubuntu use(swap and ext4) and write to MBR the win 7 boot-loader(using EasyBCD), so I delete them and use EeasyBCD. At this stage, I had 2 partitions: NTFS for XP and NTFS for Win 7, and the Win 7 boot-loader(and XP) worked pretty well.I install the latest testing of Debian(6 RC2) from DVD1 using this guide, except I choose to use the graphical installer, ext4(not ext3 as there), install the desktop environment, and choose to install grub(even know it didn't asked me). The swap partition I set is 3 GB because my RAM is 2 GB, even know that ubuntu set it in the past to 2 GB.The installation went pretty well, just when come to grub package, it says that there was an error with installing grub package(it didn't told me what), I had no choice, so I choose to skip over grub/lilo and finish with no boot manager. I was thinking to myself: "So I couldn't install grub, at least I have the Win 7 boot-loader(which contain XP loader), and maybe Win 7 boot-loader will recognize Debian too.". But I end up with no boot at all.It told me than when choose not to install boot-manager that I need to load /vmlinuz and give it the parameter root=/dev/sda4(my deb partition).I think that if I could install grub, I could load all my boots("sudo grub update" right?).How can I fix it?
