Im geting syslogs from multiple servers, and Im having trouble to understand some syslog logs, here is one example
<189>12593340: 16596512: Jul 6 20:31:09: %PARSER-5-CFGLOG_LOGGEDCMD: User:someuser logged command:no 1480
the first number inside <> is the priority, but the two numbers after that: "12593340" and "16596512" I dont know what their are.
Does anyone knows what are those numbers?
how many formats the syslog logs has?

This is specified in the Syslog RFC:
https://www.rfc-editor.org/rfc/rfc5424#section-6.2.1
Some years ago I wrote a Shell script to calculate the numbers:

One of the data elements produced by the finger command gives information on how long a logged in session has been idle. Where does finger get that information from on RedHat? I've looked in /proc/<pid>/ but did not find anything useful, and the documentation doesn't go into the commands implementation.
So, where in the system is finger (or w) pulling this information from?
The finger program get's this information from utmp file located at /var/run/utmp.

What command line would give me a list of programs each logged in user is executing for a Linux server using bash?
You can use the w command for this.
As #ivanivan mentioned, a more complete listing can be accomplished using ps, usually coupled with grep to filter out what you don't want.

I am looking for a command in bash to change the last modified and created timestamp to be changed to present time.
How do I do it using shell command/script?
Thanks!
touch will update the access and modification times (or only one of the two with -a or -m respectively).

Hi every one
on a web server running Centos 6 with 4 Network Interfaces, we have to setup/Merge all 4 interfaces to be shown / used as a single NIC, we know it's possible but we forgot the technical name of the solution, we need just the name to google it if it's possible.
Thanks
The word your looking for is "bonding". That's what it's called in Linux.

I have a rogue Apache process running on a Centos 6 Linux server, which is running up to 55% CPU and wondered how I can scrutinise exactly what function(s) it is performing? From the 'top' command I have its process ID, but how can I drill in to what it's up to?
Thank you
If you really want to see what it's doing, get familiar with the strace command. It will show you the system calls your process is making, but I imagine it would be a terrible tool for finding out performance issues. For that, take a look at something like gprof.
