Amazon S3 bucket commands

May 11th, 2017 No comments

1. Delete an S3 bucket and all its contents with just one command

Sometimes you may end up with a bucket full of hundreds or thousands of files that you no longer need. If you have ever had to delete a substantial number of items in S3, you know that this can be a little time consuming. The following command will  delete a bucket and all of its content including directories:

aws s3 rb s3://bucket-name –force

2. Recursively copy a directory and its subfolders from your PC to Amazon S3

If you have used the S3 Console, at some stage, you’ve probably found yourself having to copy a ton of files to a bucket from your PC. It can be a little clunky at times, especially if you have multiple directory levels that need to be copied. The following AWS CLI command will make the process a little easier, as it will copy a directory and all of its sub folders from your PC to Amazon S3 to a specified region.

aws s3 cp MyFolder s3://bucket-name/Foldername — recursive

aws s3 sync “My Folder” s3://bukcet-name/“My Folder”

3. Display subsets of all available ec2 images

The following will display all available ec2 images, filtered to include only those built on Ubuntu (assuming, of course, that you’re working from a terminal on a Linux or Mac machine).

aws ec2 describe-images | grep ubuntu

Warning: this may take a few minutes.

4. List users in a different format

Sometimes, depending on the output format you chose as default, when you invoke long lists – like a large set of users – the display format can be a little hard to read. Including the –output parameter with, say, the table argument, will display a nice, easy-to-read table this one time without having to change your default.

aws iam list-users –output table

5.  List the sizes of an S3 bucket and its contents

The following command uses JSON output to list the size of a bucket and the items stored within. This might come in handy when auditing what is taking up all your S3 storage.

aws s3api list-objects –bucket BUCKETNAME –output json –query “[sum(Contents[].Size), length(Contents[])]”

6. Move S3 bucket to different location

If you need to quickly move an S3 bucket to a different location, then this command just might save you a ton of time.

aws s3 sync s3://oldbucket s3://newbucket –source-region us-west-1 –region us-west-2

Mount windows/linux disk using kpartx

May 10th, 2017 No comments

This post will guide you through how to access the contents of the virtual disk (LVM disk) directly so that you don’t need to boot the VM or when VM is not booting and you want to recover the data(windows or linux)


[[email protected] ~]# lvdisplay | grep centos
LV Path /dev/VolGroup/centos
LV Name centos

We need to create device maps from this LVM device’s partition tables.

kpartx -av /dev/VolGroup/centos

add map VolGroup-centos1 (253:8): 0 9912042 linear /dev/VolGroup/centos 63
add map VolGroup-centos2 (253:9): 0 562275 linear /dev/VolGroup/centos 9912105
add map VolGroup-centos : 0 562212 linear 253:9 9912168

Now we can mount the image and grab any files we may need.

mkdir /mnt/centos

mount /dev/mapper/vbox-centos1 /mnt/centos

Once we are done accessing our files, we can go ahead and unmount the partition and delete the partition mappings.

umount /mnt/centos

kpartx -d /dev/VolGroup/centos

Kill restore process in new cpanel

Kill restore process in new cpanel


In new cpanel/WHM when we try to kill restore process it is still showing in WHM >> restore full backup. Below are the steps to remove that process from WHM.

You can manually mark the transfer as completed using the following instructions:

Ensure the transfer is no longer running by clicking on the “View” option under “Sessions in Progress” for this transfer. In the new window, there will be a line that looks like this:

You may close this window and view the transfer on the command line: /usr/local/cpanel/bin/view_transfer 1071601843quick20141013154952IAZhRro

Access your server via SSH and run that command (the transfer name will be different on your server):

/usr/local/cpanel/bin/view_transfer 1071601843quick20141013154952IAZhRro

As an example, you might see output like this:

Transfer running with pid: paused
[795 ][MASTER ]: Start Session
[795 ][MASTER ]: Version: 1.9

You will note that the master PID for this transfer is xxx. If the process still exists, and the transfer has failed, then you can kill that process:

kill -9 xxx

The next step requires you to change the entry for this transfer in the whmxfer.sessions table in MySQL. Find the entry with the session ID for your migration. In the example we have been using, it’s ‘ 1071601843quick20141013154952IAZhRro .’ It will look like this:

mysql -e “select * from whmxfer.sessions where sessionid=’1071601843quick20141013152137YIVT7Ze'”
| sessionid | initiator | pid | version | target_host | source_host | state | starttime | endtime |
| 1071601843quick20141013152137YIVT7Ze | quickrestore | 21295 | 1.9 | | localhost | 50 | 2014-10-13 08:21:37 | NULL |

You will need to change the ‘state’ field to 100, and change the ‘endtime’ field from NULL to a time after the ‘starttime’ field:

mysql -e “update whmxfer.sessions set state=’100′, endtime=’2014-10-14 09:37:52′ where sessionid=’1071601843quick20141013152137YIVT7Ze'”

If you check it again then you will notice that process ended.

| sessionid | initiator | pid | version | target_host | source_host | state | starttime | endtime |
| 1071601843quick20141013152137YIVT7Ze | quickrestore | 21295 | 1.9 | | localhost | 100 | 2014-10-13 08:21:37 | 2014-10-14 09:37:52 |

The transfer should then no longer appear under “Sessions in Progress.”

You can reconfirm the same by login into WHM.

How to replace MySQL with MariaDB in cpanel

September 30th, 2014 No comments

Backup existing MySQL data

Make sure to save all existing data just in case there are any issues.

cp -Rf /var/lib/mysql /var/lib/mysql-old
mv /etc/my.cnf /etc/my.cnf-old

Disable the targets so cPanel no longer handles MySQL updates

The following will mark the versions of MySQL we distribute as uninstalled so they are no longer maintained by cPanel/WHM

/scripts/update_local_rpm_versions –edit target_settings.MySQL50 uninstalled
/scripts/update_local_rpm_versions –edit target_settings.MySQL51 uninstalled
/scripts/update_local_rpm_versions –edit target_settings.MySQL55 uninstalled

Remove existing MySQL RPM’s so theres a clean slate for MariaDB

The below command will uninstall the MySQL RPM’s!

/scripts/check_cpanel_rpms –fix –targets=MySQL50,MySQL51,MySQL55

Create a yum repository for MariaDB

vi /etc/yum.repos.d/MariaDB.repo

place the following inside of it depending on the DISTRO (

name = MariaDB
baseurl =

Remove php from the /etc/yum.conf file then run the following commands

yum install MariaDB-server MariaDB-client MariaDB-devel
/etc/init.d/mysql start
/etc/init.d/mysql restart

Add php back to the /etc/yum.conf file to ensure future php updates don’t get clobbered

Rebuild easyapache/php to ensure modules are intact/working

/scripts/easyapache –build


CVE-2014-7169 BASH Shell Shock Vulnerability for Linux

September 29th, 2014 No comments

What is CVE-2014-7169 / Shell Shock Vulnerability?

GNU Bash through 4.3 bash43-025 processes trailing strings after certain malformed function definitions in the values of environment variables, which allows remote attackers to write to files or possibly have unknown other impact via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution.
NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271.
In short Shell Shock vulnerability allows remote attackers to execute arbitrary code given certain conditions, by passing strings of code following environment variable assignments.
The Shell Shock vulnerability is considered bigger than Heartbleed as it’s affecting all versions of bash and it’s still unclear from when and adding to that linux bash is not only running on linux webservers but other embedded devices as well such as Mac Laptops

Test your server bash version using below command

bash –version
/bin/bash –version


GNU bash, version 3.2.25(1)-release (x86_64-redhat-linux-gnu)
Copyright (C) 2005 Free Software Foundation, Inc.

Check if your server is affected

[email protected][#] env x='() { :;}; echo vulnerable’ bash -c “echo this is a test”
bash: warning: x: ignoring function definition attempt
bash: error importing function definition for`x’
this is a test

If you get the above output then you are safe. But,  if you get the below output then you are affected.

[email protected][#] env x='() { :;}; echo vulnerable’ bash -c “echo this is a test”
this is a test

To fix it follow below steps:

For RedHat/CentOS/Fedora/RPM based OS:

Note:: This is a temporary fix released by Red Hat Security Team. The team is still working on a full fix which is expected to release soon.

[email protected][#] yum upgrade bash

For Ubuntu / Debian

apt-get update && sudo apt-get install –only-upgrade bash
