Dec 7, 2010I'm working on a server and noticed that the to RAID5 setup is showing 4 Raid devices but only 3 Total devices. It's on a fully updated CentOS 5 system that only has three SATA drives, as it can not hold anymore. I've done some researching but am unable to remove the fourth device, which is listed as removed. The full output of `mdadm -D /dev/md2` can be see below. I've never run into this situation before.Anyone have any pointers on how I can reduced the Raid Devices from 4 to 3? I have tried
mdadm /dev/md2 -r failed
mdadm /dev/md2 -r detached
but neither work and since there is no block device listed I'm not quite sure how to get things back in sync so it's only seeing the three drives.
/dev/md2:
Version : 0.90

General :: How To Restrict Use Of A Computer?
Nov 22, 2010Suppose that some person is insomniac because of a bad habit of chatting on the IRC every night until 3AM. That completely ruins this person's life because he is unable to wake up on time to attend his exams, because he will be fully exhausted everyday and will feel depressive.
That person is conscious of this bad behaviour, and would accept any help including installing a software on his own computer granting me admin privileges to install it.
Do you know of such a software that ideally would: Would prevent use of the computer at certain time ranges, let's say 11PM — 6AM Would gracefully shutdown the computer at the beginning of that time range (not killing all the applications brutally), and shutdown it if the user attempts to switch it back on Would warn 10 minutes beforehand Could occasionally be disabled if I give a one-time password to that person?
That person uses Linux, and I am curious of knowing what is available for that purpose. It is kind of a parental control, but not for a child.

Apr 7, 2011I m new with Fedora 14, and i have a basic business case :
I want to setup a user which should
- only connect to the server with SSH (ex.: no X11 connection).
- cannot change its shell
- cannot do any SU / SUDO command
This user is very similar to a SERVICE user, as I expect him only to run a single program (its shell).
General :: Restrict A Program's R/w Rights To Nothing?
Sep 15, 2011Under Linux, I would like to be able to launch anything from command line in a "safe" environment, i.e. be assured that it can't read or write any file on my computer, and even better if it couldn't access the network.I thought about creating a user with reading rights only in the current folder (and nowhere else), and su to this user to launch the command, would this work ? And what about the network ?

Apr 8, 2011Prior to purchasing this Toshiba L675D I was able on my old HP to explore other distros, but there seems to be some incomparability existing with this model that restricts 10.10 but accepts 10.04, kernel thing I assume. But in all other attempts to install, Mint, open Suse etc it loads the kernel then the Live CD freezes on a black screen blinking cursor. Have tried nomodeset with no success. Obviously Toshiba is no help with Linux and win 7 forum even cautions against creating an extended partition. Oh out of the box this baby had 3 primaries, one a recovery and hidden. Just an FYI

Apr 13, 2011I am running RHEL release 4 (Nahant Update 6). I currently have a fax server that has been encountering issues recently after hours. My boss would like our helpdesk to monitor the status of these modems throughout their shift. This has led to a request for a helpdesk account to be created on our linux box that only has access to a few commands. Is there a way to limit the new user to only have access to the following commands?
cd
less
cat
Additionally I would like to create a script for them to run that would chmod our modems when necessary since their permissions reset after a power cycle. BUT not give them access to the chmod command, just chmod through that script for those specific devices.

Security :: How To Restrict Permission To Ssh User
Jan 26, 2011I would like to allow a user to login through SSH but with different permission coming from different ipaddress.
For example, a user "tester" login to SSH through 192.168.1.1 and another user login with the same login id "tester" but from different ip 192.168.1.2.

Security :: Restrict User To One Directory Only?
Jan 6, 2010Here's the beginning of the issue: I'm running Fedora 12 with httpd and sshd. I want to create a user with a scponly shell for sftp access, but this user should ONLY be able to view /the/http/base/dir and its subdirectories. The user should not be able to see or get into directories above the httpd base. Someone mentioned creating a chroot jail for sshd and binding the httpd base to that dir, but this seems like more work than is necessary for the application I wish. Also mentioned was creating a user, say user1 with a selinux user setting of staff_r. I have read the articles and creating a user of staff_r isn't overly difficult, but how would I make it where staff_r would be restricted to where I want them to be? If I'm not mistaken, that would require changing the context of /the/httpd/base/dir?

Server :: Postfix Configuration: How To Restrict Use Of CC

When I run this test, as expected, the email is delivered to validuser. However, postfix also delivers it to user1 and user2 despite the fact that the sender does not belong to my domain. I have implemented client, helo and recipient restrictions as below. How do I prevent the malicious use of CC as described here?

Fedora :: Restrict The Tablet Area To Screen 0?
Jul 10, 2011I have a dual head setup on Fedora 15 with nvidia drivers: two separate X screens (no xinerama, no twin view). Screen 1 is at right of Screen 0. My Wacom tablet is recognized by the xorg server and the whole tablet area is mapped to the whole area of Screen 0 which is exactly what i want. However when the stylus goes beyond the right edge of the screen, the tablet area gets mapped to Screen 1 and there is no way to come back to Screen 0. What i would like is to restrict the tablet to Screen 0 all the time. I used to do this in Fedora 13 by adding a file named
Code:
/etc/X11/xorg.conf.d/50-wacom.conf
in which there was a line
Code:
Option "ScreenNo" "0"
It doesn't work anymore. The option seems to be ignored by xorg since it doesn't appear anymore in
Code:
/var/log/Xorg.0.log
How can i restrict the tablet area to Screen 0?
