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 :: Create User With Password And Read / Write Privileges For Program Database

Oct 11, 2010

Unless your distro has taken care of it Centos 5.5, you'll need to create a user with a password and read/write privileges for program database. You can do this using the MySQL command line client if you are familiar with it. Well I am not familiar with it, so I wam wondering how to do it. As well when I run

mysql - p program </usr/share/program/mysql.sql>

It asks for a password. how do i find out this password.

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 :: Site Giving Database Read Error

Jun 7, 2010

I had my server going pretty good. Two sites being hosted. Wilmingtoncoc and Mikealrhughes. Last night we had Thunderstorms and Tornadoes come through. While I was out Tornado chasing. We lost power here for an instant and back on. When I came in the server was off. So I booted it back up. The mikealrhughes site is still working good. The Wilmingtoncoc site is giving me a Database read error, it is a WordPress site. Also I can't log into the Server using SSH. Where do I start to repair the problem? Do I reinstall SSH if so what is the command I use? Then how do I solve the WordPRess Database problem? Also when I try and issue a command from the Server with sudo in front of it I get an error message that says - sudo: must be setuid root - whatever that means. I couldn't find that in any of the books I have.

Fedora Security :: Error - Cannot Read /etc/shadow: Permission Denied

Jan 20, 2010

This is weird, today I updated my system and while trying to visudo from single user mode got

"cannot read /etc/shadow: Permission denied"

which kept me from doing anything until I switched to file permissions of 400 on shadow, then back. Is this being experienced by anyone else or just me? /etc/security/limits.conf doesn't seem like it wants to change in enforcing mode either and I can't find any alerts to provide clues on the situation.

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.

Ubuntu :: No Password - Read Only User (Limited Permissions)

Nov 9, 2010

I'd like to add essentially an anonymous user, which does not require a password. Second I think it's probably a good idea to only give this user very limited permissions, is there a way I can restrict the commands that they can run to a list (i.e. they should be able to run scp, ls, cd, maybe a few more, but not much)?

General :: API Mismatch: Nvidia - Error: No Display Specified

Nov 27, 2010

after installing thunderbird my computer was unable to load linux (fedora 13) while loading it reaches the blue screen with logo and halts. it didnt respond to any button. then i went to a single user by Ctrl+Alt+F1 because im a total newbie and thinking that video driver is missing, i installed nvidia using yum! but the problem remains. now entering startx gives:

API mismatch: the nvidia kernel module has version 195.36.24, but this nvidia driver component has version 260.19.12. there is always this error: no display specified/etc/X11/xorg.cof file has Driver "nvidia" in the Section "Device", but it is supposed to be "nv", because it was so previously. manually editing this doesnt help.

1). is it possible to "unyum" what i did and get back the driver i used to have? 2). how can i get the display working? 3). were there any known to you cases when thunderbird could mess up display drivers?

What I want to be able to do, is have create a group, for example called "group1" and set its default permissions to read & write, instead of the usual just read.

So when I add a user into "group1" they automatically have read & write access to all files & directories which is in "group1".

Oh & I use crunchbang 10 (statler) for my desktops & Ubuntu 11.04 for my NFS/print/SSH/etc/etc server
