Difference Between /var/log/btmp And /var/log/secure

Hi All,

I know log purging happens for /var/log/secure on daily basis. I am not able to understand what triggers log purging?

I have a linux device for which /var/log/secure is growing, now it has secure.1 secure.2 secure.3 and secure.4 files.

Any input is appreciated.

Can anyone tell me the difference between a command and a utility in a Linux system?

How are they each related to a program? Is there any formal definition for them that distinguishes them?

Are there any mother boards for an i7 4770 Intel cpu that don't have secure boot in the bios?

Hi
Please see below actions.

$ touch abcd #abcd does not exist before
$ ls -l abcd
-rw-r--r-- 1 james games 0 Apr 17 15:01 abcd
$ date
Fri Apr 17 15:39:55 IST 2015

Why is there about 38 minutes difference even though I type commands in quick succession ?

Thank you.

Hello sir, i want your help to know that in order to add security to ZRP which are the files where we have to make the modifications for encryption, digital signature etc.. as i have very less knowledge regarding so plz help me from the basic level as what should be done in SZRP.

on a video im watching the instructor started with a slide that said

hardware settings
*****************

determine settings
hal dbus udev
/sys /proc /dev

then he talked about proc which i get
then he talked about /sys but the /sys path he was showing was in /proc/sys (where he changed ip forwarding settings etc)
and i know there is a /sys directory on the root
so this is confusing me a bit
whats the difference, do i really need to worry about this...am i over analysing?

Could you please tell me the difference between agent->function name() vs this->function name ().
Actually i am taking about LAR.cc file (LAR routing protocol) but these function calls can be part of any routing protocol.

As you can see below , they are calling the same function with this and agent in LAR.cc . What is the difference between when we are calling a function with "agent" or calling with "this"

I have to do some changes in this file . kindly give some information on this issue .

Hi - I have the most aggravating problem. On my RHEL 5.2 w/s using gnome (or KDE), if you select "lock screen" from the pulldown and then try to unlock the screen with your password you logged in successfully with in the first place, it comes back shaking it's head INCORRECT PASSWORD. I did some digging and the /var/log/secure file is spitting out:

gnome-screensaver-dialog: pam_unix(gnome-screensaver:auth): authentication failure; logname= uid=500 euid=500 tty=0.0 ruser= rhost= user=username

Then below that also:

gnome-screensaver-dialog: pam_unix(gnome-screensaver:auth): auth could not identify password for [username]

I find this is happening on a few of my other RHEL systems too: RHEL 5.5, 6.0, and 6.5.

Help!

I just read that in 2013 nasa stopped using windows and moved to linux quoting the need for a more stable ssystem with better security. They also said that they were using debian.

They also use lenova thinkpads for the same reasons.

My question is, what is the functionality difference with debian? Is it more stable than other distributions? If ubuntu is Debian based, what is the difference?

I'm currently using ubuntu studio Distro and very happy with it but I'm very interested in the reasons why nasa use Debian.

I have a Centos 7 minimum install VM and I want to install the bind rpm's so I can enable the nslookup. I don't have internet access because it's an secure network so no yum commands. thanks
