I recently popped in the CD that came with one of my textbooks from school and figured I would be able to rip it pretty easily, but guess what? Too my surprise I find that each chapter of the textbook has it's own PDF file and that each one is encrypted. Is there anyway I can decrypt the PDFs and merge them all into one?
View 5 RepliesI recently bought a bigger drive for my laptop which had an encrypted LVM PV on it that I wanted to get rid of for performance reasons. I hit a few snags with the migration and documented it on my blog.
Fancy reading it? Go to my blog post about upgrading harddrive with encrypted LVM.
I have a computer running Fedora 14 and when I installed it, I chose to encrypt the drive.
I've recently changed the way I have things set up and don't want the encryption any more. From what I've read there is no way to simply and easily remove the encryption, so what I would like to do is input the pass phrase remotely.
so, Is there anyway I can type in the pass phrase remotely, or remove the encryption?
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?
View 1 Replies View RelatedSoon after I installed F12 I realized that I mixed / and /home partitions during the installation, resulting having an enormous / and a relatively small /home.
Since I want to avoid resizing the partitions*, is there any way to make Fedora use a certain amount of disk space on / as part of /home. Is this possible? And if it is, are there any drawbacks?
*I actually tried using a live usb but gparted wouldn't let me do any modifications. The volumes were unmounted though...
I am a squat on advanced Apache work. I would get a basic SSL functionality to work. So URL...works fine and gets me all the login windows I designed. however currently all the images and other extensions like .pdf are also using the https routing.some image referred on that https link e.g. URL...can be displayed using https but not http.I would like to JUST limit https usage to the login window html and ALL other images pdf's not secured html ( one that do not need password ) should use HTTP NOT HTTPS.

So I have a jpg image file that was encrypted using 256-bit AES, and I know the passphrase. That is ALL the information I have about the file. Is there a way (under Ubuntu, preferably but not necessarily on the command line) to decrypt this file?

View 1 Replies View RelatedI'm an absolute beginner at encryption. gpg and keys still have me somewhat mystified, so please forgive me if the following seems like a stupid question. I'm looking at encryption software for my smartphone. I've found a Java program called TinyEncryptor that uses the TwoFish algorithm and claims to be a shell for the "Legion of the Bouncy Castle" libraries. It just uses a passphrase; there are no keys involved as far as I am aware.
Naturally, I would like to be able to decrypt files on my desktop that I've encrypted with this program. So far, I've not had any success with finding one.
I have a major major issue with an encrypted /home directory. I had used encryption on my home directory when I installed 9.10. However, I had not noticed that I needed to store the automatically generated passphrase anywhere. Now, upon installing 10.04, my home directory would not decrypt. I checked my .encryptfs directory and the wrapped-passphrase file is GONE. I only have the Private.sig files from my 9.10 installation and of course know the login password I binded to the passphrase. I can see my .Private directory with filenames starting with ECRYPTFS_FNEC_ENCRYPTED. Now, my PhD thesis which I have to deliver in 2 weeks is in there. With no backups. How to recover my data. If no 'normal' method would work, is it possible to use a brute force attack and feed it my login password?
View 3 Replies View RelatedUbuntu 10.04 LTS Ran some updates,finally got around to rebooting. When I rebooted, It came up with Some errors about missing files. Came to discover my home directory was not decrypted. I simply had a readme file that said to run "encryptfs-mount-private". When I do it doesn't tell me the passphrase is incorrect, it tells me
Code:
Inserted auth tok with sig [xxxxxxxxxx] into the user session keyring You do not own that encrypted directory and I do own it. If I put in a different pass it tells me it's incorrect, I'm logging in fine, but my home directory is remaining encrypted.
i need to find a way to securely authenticate a decryption mechanism of some sort where the authentication is provided remotely without any user-interaction. Right now i have a number of boxes that all inform a central server when they are online. When they do this an OpenVPN connection is set up between them and the server.
However, i have been given the task to ensure that the scripts involved in this process are encrypted by default. This requires some form of self-decryption, which to my mind kind of goes against the whole idea of encryption/authentication in the first place. I need some way to leave decrypted the bare essentials required to boot a box and securely connect to the central server automatically. Then the server would automatically send a key/passphrase and the rest of the files on the box would then be decrypted on the fly.
I have 2 partitions on my 50 GB HDD. 1st 20GB (ubuntu), 2nd 30 GB (Data). I want to merge data partition to the first one. How can I do that?

View 9 Replies View RelatedI want to make a little script/program/something that can organize my TV show collection. I'm italian, so I store for each episode the .mkv file and the .srt file. To let VLC automatic recognize the .srt file, I use the same name for the .mkv and the .srt.
That solution is quite optimal, but we can do better: a program that watches a directory and it's subdirectories and automatically runs mkvmerge if it detects files with the same name in the same folder.
I'm a Java programmer, so I can easily make a program that finds files with the same name and runs mkvmerge.... My problem is the directory listener. I found incron, but the problem is that it don't add the listeners to the subfolders of a folder.
how to split two files like
big.zip.1
big.zip.2
then, my second is how to merge them like windows
in windows, i can use copy /b
in linux,

cat big.zip.2 >> big.zip
I'm totally new to Linux and this website. I was wondering if anyone had or could help me create a shell script that would merge two files from two different directories and then have that new merged file in a third differnt directory.The merged file would need to eliminate duplicates and sort the contents.

"Merging" may not be quite the right word but that is the desired end result.
Scenario: many Solaris 10 servers, each with various local users. We want to set up LDAP for all for all of them. LDAP server is set up, procedure for getting other servers to use it for user authentication is documented and tested. The question is how to handle users that are in LDAP who also exist as a local user on a given machine.
It appears that the usernames on both sides follow a convention and therefore match but obviously the userids will not match. Local user joe has userid 1234, LDAP user joe has userid 56789.
The way I see it we'll have to:
1. move local user joe's home directory to the path that LDAP user joe will want
2. change local user joe's userid to that of LDAP user joe
3. change joe's files' owner to his new userid
4. remove local user joe
5. finally configure LDAP
Is this a rational procedure? Is there a more effective method? I'm not looking forward to this as there are many servers and each of them have a different set of local users, each with different userids which will have to be handled manually and individually therefore not even scriptable much.
How does coalescing of requests takes place during merging if the following scenario occurs.. say request for sector number 3 and 5 already exists...and a new request for sector 4 arrives, then if it front merges with 5, will it also back merge (i.e coalesce in this case) with 3 ? if it happens ..which functions are called? and how do we get to know whether a single merge or multiple merges have taken place?

I had two ext4 partitions; one had data and another didn't. I wanted to merge them using Gparted, but couldn't find the option. So, I deleted the second partition making it unallocated and used the 'resize' option to merge both the partition. Now, the partitions are merged but I LOST THE DATA..
I am seriously f**ked up.... What can I do to get those data back. I haven't done anything to the partitions after data: no adding data, no formatting.
I have multiple strings (eg. say two, firstLIST=(0 1 2) and secondLIST=(2 3)) and want to create a single string composed of their unique sorted elements. For the sample strings above, I'd like to build masterLIST=(0 1 2 3).I suppose I could write the elements of firstLIST and secondLIST to files
Code:
echo ${firstLIST[@]} > firstFILE
echo ${secondLIST[@]} > secondFILE
then use
Code:
sort firstFILE secondFILE | uniq > masterFILE
as this gives me a file populated with the elements I'm after, but I'm not sure how to read the elements back into masterLIST... and it doesn't seem "right" to create files to accomplish this. Is there a way to do this by manipulating the strings ${firstLIST[@]} and ${secondLIST[@]} directly? The closest I've come (not close at all) is
Code:
masterLIST=${firstLIST[@]}" "${secondLIST[@]}
but masterLIST built this way has only one element
Code:
$echo ${masterLIST[@]}
0 1 2 2 3
$echo ${#masterLIST[@]}
1
and I don't have access to the individual digits to then try to figure out how to remove duplicates.
I have a latex code file which links itself to many other latex files. The syntax is as follows:input{*path of file to be inputed*}The path is relative to the current working directory, so if my file is stored in /home/kevin/mybook.tex and I want to include a file in /home/kevin/latexstuff/copyleft.tex I simply write:input{latexstuff/copyleft.tex}
The latex compiler includes these files just as if they had been copied and pasted into the main latex file at the point specified. My problem is that I have a document which depends on quite a bit of these input commands,ut I am trying to use a latex preprocessor (ratexdb, adds database fields to your latex documentshich does not support input commands, leaving my file only half processed.So I was wondering: is there any easy way to parse through my main file, detect only the input commands, interpret the syntax and include the files specified (where specified)nd produce a second, populated file, which can then be processed by ratexdb?
During the past eight years I've used a number of computers with different operating systems and browsers. On each one I made a habit of using the bookmark utility of each browser and saving the bookmarks file. I never ensured the continuity of the bookmark file - with each new computer I started a new bookmark file. Even when I was reinstalling the operating system I didn't import the old bookmark file in the newly installed browser: I've always started a new bookmark file. As a result I have tens of bookmark files for Firefox (json format - some kind of xml?) and IE (html file format?) each one containing hundreds or thousands of saved links. I have also some files containing links in text format (created usually when I was using someone else computer).
I would like to be able to manage this bookmarks files by using some sort of "bookmark manager" software. The "bookmark manager" should be able to merge the bookmark files into a single collection/file. It should be able to identify and remove the duplicate entries (I have timely versions of the same bookmark file) and also it should be able to group the entries/links on categories (for example the bookmarked articles on codeproject.com should be grouped under the codeproject category). Not to mention that it should provide a search facility to quickly locate the interesting bookmarks. I couldn't find such software in ubuntu software center. Do you know something that even comes close to what I need?
I am very new to LVM, as well as not especially experienced at linux, and have some questions about how lvm works. A few months back I set up a server running FC10 and tried creating Logical Groups during the the initial setup. We've realized that we are not using all the available space on the physical drive, and I realized that for some reason (I'm thinking this might have been the default?), we initially created two Logical Groups (VolGroup00 and VolGroup01) and it appears two Logical volumes in each (LogVol00 and LogVol01). LogVol00 in VolGroup00 is mapped to /, and the other Group was actually unused. I figure that it would be simplest to just use all this space mapped to /, so I thought the thing to do would be to simply merge VolGroup01 to VolGroup00. I tried this:
[root@office mapper]# vgmerge VolGroup00 VolGroup01
Logical volumes in "VolGroup01" must be inactive
So after a bit of research, I tried this:
[root@office mapper]# vgchange -a n VolGroup01
Can't deactivate volume group "VolGroup01" with 1 open logical volume(s)
So apparently There's an open volume, but I don't know how to go about closing it. I removed the LogVol00 from that group, but LogVol01 won't budge.
[root@office mapper]# lvremove VolGroup01
Can't remove open logical volume "LogVol01"
So how do I go about closing this Volume? At one point, there was some output that told me LogVol01 was being used as swap space. How do I handle that?
