Jan 27, 2010

What, if any, significance is there to the following message shown in the rkhunter.log?

What need would there be for hidden directories to exist in /?

Ubuntu :: Hidden Folders In The Home Folder That Aren't Hidden?

May 6, 2010

just a general weirdness, but some folders that are in my /home folder don't show up. if i check "show hidden folders", they still don't show up. for all terms and purposes, they are simply not there. however, if i search for them through the search tool, or beagle, they show up as being in my /home folder. so, anyone have any idea how this happened, or how i can remedy this?

Ubuntu Security :: Sshd And Hosts.deny Not Always Observed?

Jan 18, 2010

I'm having troubles trying to understand this problem:my homeserver until yesterday had a public IP, staying on network, with sshd running and all was fine;this evening I changed the IP, giving it a local lan address, and what happened if I tried to connect to it by ssh?I got an error about "Connection closed by remote host". Google helped me finding that was regarded to hosts.deny file, that was actually containing a lineALL:ALLthat I commented, and all was fine.My question is: why the hosts.deny (that has never changed) was observed only with the local IP?I tried to switch back to the public IP and leaving ALL:ALL, and it did connect without any problem

Ubuntu Security :: Restore The Original Image File That Have Hidden Data In With Steghide

Jan 27, 2011

i'm wondering if it's possible to restore the original image file that you have hidden data in with steghide. The basic Idea is you have a photo using gpg sign it and then embed the signature. then remove the signature at a later time and check it with the signature. I hope another "inverse" algorithm doesn't need to be written to undo the first (if a "inverse algorithm is possible). This assume you already have the pass phrase or that there is no pass phrase. I already know how to retrieve the original file just want to remove the hidden data from the Image and restore it's attributes.

Ubuntu Security :: AppArmor Protect Devices And Limit Their Access To The File System?

Nov 9, 2010

This might sound really stupid, so you'll all have to excuse my lacking knowledge. I read that USB attacks get more and more common, like putting in an USB stick with a malicious autorun script on it, and it's game over. Can AppArmor protect devices and limit their access to the file system?

Ubuntu :: Where Are User Folders Hidden

May 18, 2010

I had a minor disaster and lost a lot of data. I used PhotoRec to see what it could recover, it saved them to my home directory. 488 folders I cant do anything with as I don't have permission?? I set up root and gave myself admin power but still cant delete them. If I log in as root, where can I find my home folder so I can delete the majority of these folders. Most unfortunately have nothing of value in them.

Ubuntu :: Nautilus - Two Folders With Same Name (One Hidden Other Shown)

Jun 5, 2010

Actually, Nautilus allows two instances of the same folder, or two folders with the same name in the same directory, as long as one is hidden (with the .prefix) and the other is shown. It happens that, if during a download (through a download manager or a torrent client) the user adds the . prefix to the download folder, another will be automatically created by the application (let's say Transmission for example) and the download would continue to that new folder. If any renaming happens (or if the original folder is restored), the download will resume to the folder with whichever initial name. Eventually, the user will be left with an unusable/corrupt complete download.

Ubuntu :: Removing Unused Dot (hidden) Folders In The Home Directory?

Jun 1, 2010

If someone manually partitions their home and root drives and overtime they end up with a lot of dot folders (.burgerspace for example) in their home directory. Is there a quick way to get rid of all the dot folders whose program is no longer installed? For example if I completely removed BurgerSpace in Synaptic, the .burgerspace folder would remain.

Ubuntu :: How To Find / Delete Unused Hidden Config Folders

Oct 12, 2010

I recently moved to a new machine, and I copied my entire home folder across. This included lots of hidden (starting with '.') folders, and in many cases they are config folders for packages which I have not installed on the new machine. They are taking up space, so I would like to delete them, but to go through manually and figure out which ones I need would be very laborious. Is there a way to find, and perhaps delete, config folders for packages that are not installed?

Ubuntu :: Hide 'hidden' Folders In Save And Open Dialogs?

Mar 14, 2011

Nautilis is very good at hiding or showing 'hidden' files and folders (names starting with .) but using any other program to save or open a file, I have to scroll through reams of hidden to my storage folders. Is there a way to make the save and open dialogs 'hide' the 'hidden' files? Is it different for different programs?

Ubuntu Servers :: Maintaining Hidden Windows Folders With Samba

Sep 1, 2011

I've set up a ubuntu server at home with the intention of sharing files with windows clients, so I've installed samba. I have no security issues so I've allowed public access to the shares and I can access them fine from all windows machines. I also need to preserve the dos attributes for files and folders using 'map hidden', 'map system', 'map archive' which works great for files but not for folders. I've got a number of folders from my windows box which I would like to keep hidden (for tidiness more than anything) but when I transfer them to the samba share, they become visible again and I can seem to control their visibility at all from windows or from ubuntu. Do I take it from this that samba can only manage to maintain dos flags on files and not on directories?

This is the relevant part of the samba.conf file

log file = /var/log/samba/log.%m
passwd chat = *Entersnews*spassword:* %n
*Retypesnews*spassword:* %n
*passwordsupdatedssuccessfully* .
map hidden = yes .....

comment = Shared files
path = /usr/media

Software :: Evolution Is Showing Hidden Files And Folders In Folder Tree

Oct 31, 2009

I am using evolution for my email client, and it shows me hidden files and folders in the folder tree. Basically, my email folder is in a unix folder on a system, and that system logs me into my folder when I try using evolution. The downside is that files like .bashrc, .bash_profile and other weird stuff end up in the foldertree view

See how the tree would show bashrc and .lynxrc?The folder "documents" shouldn't be showing either.Yeah, that's really annoying. It showing the contents of the $HOME folder that I login to.In thunderbird those things wouldn't show.It must be evolution specific.Anyone have an idea how to fix this issue?

Fedora :: GRUB Error 18 - Couldn't Read Configuration File

Apr 5, 2010

I'm playing with Fedora 12 and can't get GRUB to work. To boot, I've been using GRUB4DOS. While that works fine, I'd like to figure out what's wrong with regular GRUB 0.97. After the initial installation, GRUB came up on reboot, but it was broken -- it couldn't read the config file apparently, and no commands would work correctly. So I attempted to reinstall grub via the grub prompt. No matter what I do, or which hard disk I install GRUB on, I get "Error 18". I tried using the "grub-install" command as well as the prompt, and that did the same thing.

My system here is an ASUS M4A785TD-M EVO mo/bo. I've got four hard drives. Two 1TB SATA drives and a couple of PATA drives (300 and 500GB) on a Si608 controller card. Using the BIOS "BBS" boot menu, I can boot NTLDR and BOOTMGR off active partitions on any of the drives (with proper Boot.ini modifications to handle the change in drive order). GRUB4DOS works as well, and will boot Fedora 12 correctly off any of them (with proper menu.lst ministrations). But GRUB 0.97 that comes with Fedora just refuses to do anything other than say "Error 18".

Security :: Checking What Processes Are Hidden?

Jan 13, 2010

I post this to have a memo about how I looked into this problem. You can use this command to check what is hidden.

/usr/lib/chkrootkit/chkproc -v -p 3 | grep /proc/ | sed 's/.*(/proc/[0-9]*).*/1/'| xargs -n1 -I %%% cat %%%/cmdline

If it doesn't output anything, then nothing is hidden currently. This usually means that a process was started between the ps command and the /proc check of chkrootkit. You can check what those command(s) are by running the above in a loop, with high priority.


Does anyone know how to get rid of these false positives while retaining other functionality of chkrootkit?

Ubuntu Security :: TrueCrypt - Hidden Volume Protection ?

Jan 22, 2010

I installed TrueCrype 6.3a on my 8.1 Ubuntu. Everything went fine until I got to the part where I need to protect my hidden volume from damaged caused by writing to the outer volume (these instructions: [url] ). I can't find the checkbox to "Protect hidden volume from damaged caused by writing to outer volume". The closest thing I can find is an option to "Protect hidden volume when mounting outer volume". Intuitively these don't sound the same to me. There are 2 difference between my setup and the instructions; 1) the instructions appear to be written for Windows and not Linux. 2) I am using a file volume and not a partition volume.

Does anyone know where the option is to protect the hidden volume when writing to the outer volume?

Security :: How Plausibly Deniable Are TrueCrypt Hidden Volumes

Nov 21, 2010

TrueCrypt hidden volume plausible deniability is documented at [URl]deniability but how plausible is it? there is no sign of the hidden volume's existence within the outer volume even if the user is forced to disclose the outer volume password. For this to be plausible the outer volume must be used or the user has no plausible reason for having it.


If you mount a TrueCrypt volume within which there is a hidden volume, you may read data stored on the (outer) volume without any risk. However, if you (or the operating system) need to save data to the outer volume, there is a risk that the hidden volume will get damaged (overwritten). To prevent this, you should protect the hidden volume in a way described in this section.

The way described results in the outer volume properties including 'Hidden volume protected: Yes' which discloses the hidden volume's existence. The next section in the documentation has a diagram showing how the hidden volume is created at the top end of the outer volume space. Use of the outer volume must not write in the hidden volume space or the hidden volume will be corrupted. That limits the choice of outer volume file system to one of the FAT series because more sophisticated file systems do write in places across their whole space.How plausible is the choice of a FAT file system on Linux? Even on a dual boot system with the usual Windows versions NTFS is a better choice.

Ubuntu Security :: Is There Way To Make Cross-platform Hidden Files?

Oct 24, 2010

I'm sure most of you know that making a file or folder hidden is simple in the Linux world: Add a period (.) before the name. However, if you were to save such a file or directory to a flash drive, it would only be hidden on Linux systems. If you plug the flash drive into a Windows machine, Windows will happily show the file.Is there a way to make cross-platform hidden files?

Ubuntu Security :: Hidden Backdoor In AT&T 2Wire Modem/Router?

Aug 11, 2011

My 2Wire router/modem I got from AT&T for my DSL has port 3479 TCP open and I can't figure out how to close it. It's open to the entire internet. From a quick google search it's some port AT&T can use to update the modem's firmware or something.Consider how in bed AT&T is with government agencies it seems like a easy way for the government to get into my home network just by using what seems to me a backdoor put there by AT&T. Anyway to close this or secure it. Right now I'm using the hardware as my main router for my home network. I have Linsys I modded with DD-WRT. I'm thinking of re-configuring my network to use the DD-WRT router as the main router and the 2wire just as a modem. The 2wire is a hybrid modem/router and I'm kind of lazy and don't feel like re-configuring my entire network if I can just close the port.

Ubuntu Installation :: Laptop With No Removeable Media Of Any Sort?

Jun 7, 2010

I've got an Acer Aspire One. I don't like windows. I have used Ubuntu many times in the past and love it. I want to install it on this thing, but it's as minimalist a computer as it gets. No DVD drive or anything. It weighs about as much as a small bottle of soda. I have no access to USB Drives, External DVD drives, External floppies, external anything. I do have a cat but I don't think that's going to help. In fact, he's trying to step on my keyboard Anyway, I know you can do a "Frugal install" off the hard disk but I have absolutely no idea what it is.

What exactly is a frugal install? Can I partition the hard drive and leave my windows alone (Got some data, programs and porn holding me down) with a frugal install?Is there a difference between a frugal install and a fancy high-tech DVD install when it's finished (E.G Limitations, stability, chances of computer asploding)?
