So I'm going to rebuild a Centos server in order to have the disk encrypted, it's a clean install (no data on it yet) other than it was tricky getting the GPU/drivers to work properly.

So I want...

Hi, we have a brand new Centos 6.8 build, and after some discussion it seems that there is some interest in securing the entire system using whole disk encryption.

What is/are the best option/s,...

Actually this is a Centos 6.x question, but I think it fits here.

I have a client that has a pretty beefy server that will be running all sorts of VMs once I unleash it to the developers. For...

I have a somewhat interesting problem, we've decided to load balance a java application and as such I'll be running our application on four physical machines as opposed to the single machine it's...

I have a shell script that runs on our webserver logs, and grabs various useful data and then outputs this data to a .csv file.

What I want to do now is schedule a cronjob to run this script for...

Ok yeah that makes sense, thanks

Thanks again Don! :b:

Ok sorry, lets see if I can clarify from the following log sample:



qtp111659197-5776 - 05-26@09:37:34:240 INFO (TimingInfoProxy.java:41) -...

Agreed. :b:



Thanks for the hint. So here's what I did below:

awk '
match($0, /"username":"[^"]*"/) {
split($3, d, "@")
user = substr($0, RSTART + 12, RLENGTH - 17)
...

Awesome, that worked perfectly.

Many thanks again to both Don and Rudi!

Ok, so...

Thanks RudiC, the output was mostly correct, however some lines of output were just blank space after the date (I added the commas so later I can output into csv easily):

3, 05-22 ,

Hmm, I'm...

The log entries that I would like excluded do not contain "username":"email@address"So basically I only want entries that do contain "username":"email@address" to be displayed in the output

It returns the data I need, the only other issue is that it also returns counts for entries that aren't user related as the log files do contain entries that don't have to do with user activity.

Sorry about that, after your initial response I realized what I omitted what I thought was useless data was in fact important data for this task :)


Sorry for the confusion on this too, the...

Thanks, yes I would like the output sorted by increasing alphanumeric username as primary sort key, and increasing data & time as the secondary (I didn't find out until today that they want the time...

So I need to write a script that can parse our logs and give me the amount of daily activity per user on our website. Unfortunately I'm still learning the very basics so please bear with me :eek:....

Ok thanks, that's what I needed to know :b:

Hi,
I have a cron job that I want to run twice a week, on Tues/Thurs, and I want it to run three times - specifically at 10pm, 11:10pm, and 12:20am respectively.

I "think" the way to do this...

Ok, so I'm looking at it now, I have the MAC addresses for the new NICs. However, it insists that eth0 is not present.

Doing and ifconfig -a shows me new devices, eth6 eth7 eth8 and eth9 have...

Basically what the title says. Had to replace the motherboard on an HP DL380 G6 today, of course now the embedded NICs don't work because the ifcfg-eth files have the MAC addresses for the embedded...

Right now it is just a simple environment consisting of a small number of CentOS boxes, but I would like to set up central user authentication to make things easier, especially as we expand (I've...

Yep, that's what I needed to know, thanks!

This is in a CentOS 6 environment, our developer needs to be able to specify a relative path to a shared folder so that four machines can all point to the same shared directory, so I need to know the...

I don't know, that's what I'm trying to figure out :D

I emailed the guy but he has yet to respond, but I'm guessing it has something to do with the way he has them clustered.

The way...

Apologies, I will remember that in the future :b:

These interfaces do show up in ifconfig, however none of them show as being up so quite frankly I'm not sure why they're there.

I was able to...
