General :: Converting A String To An Shadow Password Format

Apr 15, 2010

I need to manually convert an string ( like with echo ) to a DES crypt format to be inserted inside a /etc/shadow file, does anybody knows how can I do that?

Maybe there are some little tool that could handle that operation, well.. I don't know, hope someone can give me a hint on that.

Software :: Check A String With Actual User Passwd (ie Password In /etc/shadow)?

Sep 24, 2009

I am trying to write a remote access module. Is there any function in linux where I can give string (password entered by user) and compare it with the actual user password stored in /etc/shadow. Since the password is stored encrypted in /etc/shadow I cannot parse and compare. So I want some method to compare if my user entered the correct password..Is there any function for that..

General :: Shadow File Password Policy?

Oct 1, 2010

Today i was going through some of security guides written on linux .Under shadow file security following points were mentioned.1)The encrypted password stored under /etc/shadow file should have more than 14-25 characters.2)Usernames in shadow file must satisfy to all the same rules as usernames in /etc/passwd.3)password for application Username should display * if username is not locked.4)If a user is locked it should be displayed as ! as the first character in second field of shadow file.

Confusion for point 1 and 2:Now i m confused as why the encrypted password should be more than 14-25 characters.Also what rules to satisfy How to check it?Confusion for point 3 and 4:There are lot of users with * as second field i guess they are not locked but according to 4th point there are lot of users with ! as first characters.How would i check whether they are actually locked or not.I m posting the output of /etc/shadow and /etc/passwd files for the account.

Software :: Convert An MD5 Hash Into Shadow Format?

Nov 28, 2010

I am trying to use John the Ripper but it doesn't take regular MD5 hashes, only shadow MD5 hashes. For example this hash: 900150983cd24fb0d6963f7d28e17f72 (which, decrypted, is 'abc') within a text file, John the Ripper does not detect because it is not shadow format. How can I convert this MD5 hash into shadow format?

Programming :: Converting String Sequence Of 1's And 0's Into Their Hexa Sequences

Apr 27, 2011

I have to write a code that converts a sequence of 1's and 0's(block) into their equivalent hexa number and copying to another array(byte). but this sequence is not always of length 8 and you are required to send strlen(sequence)%8 bits back into the string. So i've written down this code and it works well with the sample input but fails in the real program.

int Convert_encode( char * block,unsigned char * byte)
int len,iter,i,j,k,sum;
char * temp=(char *)malloc(4*sizeof(char));

General :: Password/shadow Or Group/gshadow Mismatch - Error "user Database Cannot Be Read"

Aug 6, 2010

I'm running RHEL 5. When using the GUI System>Administration>Users and Groups, I get the error: The user database cannot be read. This problem is most likely caused by a mismatch between /etc/passwd and /etc/shadow or /etc/group and /etc/gshadow. The program will exit now.

Some research showed that I need to use vipw and vigr respectively to find an inconsistency between these two sets, which I did - to make it easy I copied each from [vipw | vigr] to an excel file and did =exact(%1, %2). There are no inconsistencies.

Software :: Password Encryption In /etc/shadow?

Jun 16, 2009

I am moving my Linux server from Suse 10 to Ubuntu 9.04 and I moved the significant parts of /etc/shadow, /etc/passwd, and /etc/group over to Ubuntu 9.04. I am not able to login into the computer with the old accounts. The only problem I see is that the old accounts use Blowfish and DES to encrypt the passwords in /etc/shadow, and Ubuntu uses SHA512. If I change the passwords, the accounts will work. However; I have about 300 accounts to move, and I don't want to do that to all of them. I have tired Ubuntu Forums and talked to every linux expert I know, and no one has an answer.

Security :: Shadow Password Hashes - If My $id$ Was $5$, Which Is Sha256?

Apr 26, 2011

The /etc/shadow file contains an id of $1$, $2$, $5$ or $6$ to show the encryption method used.A salt follows this,followed by the password hash.When a user is created and a password is set, a hash is RANDOMLY generated and used as the salt to the password hash. Everytime that user logs in, login checks /etc/shadow for the $id$ and salt and runs the password given by the user through the hash mechanism ($id$) using the salt in /etc/shadow.So basically does login look at /etc/shadow for the $id$ and salt to create a hash with which to compare to the /etc/shadow hash?question 2 - If my $id$ was $5$, which is sha256, how would i go about changing this? Like is there a shadow.conf or crypt.conf or something? Can i change it per user?

Software :: Converting 3GP File To DVD Format (PAL)

May 17, 2010

I'm trying to convert a 3gp (mobile phone video) file to PAL DVD format (which is I believe MPEG2 video and one of a few audio choices, in an MPEG PS container). But while the file plays fine in mplayer and vlc, my efforts to convert it, using either VLC or devede, always seem to result in either the converted video being speed up (noticeably, we're talking twice as fast or so not 5%), or in the audio going mickey-mouse. How can I get the file converted correctly? Bearing in mind it needs to be PAL not NTSC (so a lot of stuff I might find online isn't going to work as-is)

Server :: Adding Entries Directly In Password Shadow File

Mar 11, 2011

I am working on building a customized ISO image of a server based on linux. The thing is after the server is installed and run for the first time, three users have to be created for the various services to run properly. I want this to be automated. To achieve this what is was thinking is automatically enter the user entries in the /etc/passwd and /etc/shadow files through init scripts when the server starts for the first time after the installation. I tried creating user and assigning password in one of my machine, and the /etc/passwd and the /etc/shadow entries of this user I copied it into the other machine and tried login in on the other machine and everything worked fine. How I am trying to achieve this.

Fedora :: Converting .flac To A ITunes Compatible Format?

I have been searching for a while for a program to convert .flac files I rip off of cd's with my laptop (running Fedora 11) to a usable iTunes format for my desktop (running Win XP). The cd drive on my desktop is currently broken, so my fix of ripping on my desktop, then using Rhythmbox on my laptop is temporarily unavailable.
Any suggestions? I've tried audiokonverter, soundconverter, audio-convert-mod and each come up with errors or wouldn't install.

Can I ask for some advice in converting a video (from my phone) which is a 3gp file into something more universal. I use audokonverter for audio files and this gives me a menu right-click option to convert a song from (say) wav to mp3. Is there an equivalent for videos? I am using opensuse 11.4 64 bit and have mplayer, xine and vlc installed plus the necessary codecs. Or is it simpler to use ffmpeg in a c/l environment
