Copy Paste Virtualbox enable between Linux Host and Guest Virtual Machine

Thursday, September 6th, 2018

enable-copy-paste-between-linux-host-and-guest-OS-virtual-machine-virtualbox-vbox-logo

Copy / Pasting has become a vital part of our digital lifes, not having it in our days is insane, most of our System Administration jobs / Programmer or Office (Secretary) stuff daily without Copy / Paste is a unthinkable.

Lately I have been playing with Virtual Machines as I need to test some Dev Ops related stuff I install Jenkins write and test scripts and tools inside a VM, for that to happen I needed a working VM and because I am a Free Software supporter my VM of choice is usually Virtualbox. Even though Virtualbox is not the best and most performance efficient Virtual Machine out there for a small tasks and home usage dev / testing it does a great job, I have faced a problem with Copy / Pasting not working in VBox between the VM -> Guest OS, that's why I decided to write this step by step guide to help people who face the same issue.

For people who are starting with Oracle VirtualBox and you just have Created a New Virtual Machine and installed GNU / Linux or FreeBSD one common set back problem you will experience is the the Copy / Paste functionality between the VM Host Machine and the Guest won't be working out of the box. That's pretty much annoying thing and since usually one installs different Virtual Machines with different Operating Systems as a test bed for Software installs on top of various versions of OSes the lack of Copy, Paste functionality which is not there by default makes copy / pasting programming code / commands etc. between your local Desktop notebook or remote  server Machine and the VBox Virtualized Guest mostly unusuable …

Besides that integration (sharing resources / improved VM performance) between the Host (which is for example your Desktop notebook or PC) and the Virtualized Operating system be it some kind of UNIX (FreeBSD) etc. is not optimal until you enable an extra integration between VirtualBox and your (Host OS – that in my case is Debian 9 GNU / Linux but it can be Microsoft Windows XX as well or any other *nix like OS).In order for this Integration between your Host OS and Guest OS and Copy / Paste features between the two to work you need to Enable Guest Additions CD image (Software) that is part of VirtualBox installation on the Host OS and once enabled to mount (Attach the Vbox provided Virtual CD) from within the Guest OS (that in my case is another Debian 9 Stretch Linux that is installed inside the VM) and run a script that will install the necessery VirtualBox software inside the Guest OS Linux.
 

This is done in 3 easy steps:

STEP 1: Enable Vbox (Guest Additions CD Image)


virtualbox-VM-enable-insert-guest-additions-CD-image-menu-screenshot-debian-linux

 

Devices -> Insert Guest Additions CD image

 


2. Enable Shared Clipboard and Drag and Drop from the Virtual Machine

virtualbox-VM-enable-devices-shared-slipboard-bidirectional-menu-screenshot-debian-linux
 

Devices -> Shared Clipboard -> Bidirectional

 

 

virtualbox-VM-enable-devices-drag-and-drop-bidirectional-menu-screenshot-debian-linux
 

Devices -> Drag and Drop -> Bidirectional


3. Install development packages that are required by VBoxLinuxAdditions.run script

a) First thing is to use Virtual Box program interface menu and enable Insert Guest Additions CD Image option (assuming that you have the Linux Guest OS running).

virtualbox-VM-enable-insert-guest-additions-CD-image-menu-screenshot-debian-linux
 

Devices -> Insert Guest Additions CD image


http://pc-freak.net/images/virtualbox-virtual-machine-guest-os-settings

You can do it also from main VirtualBox interface (without having a Virtual machine running) by clicking over the desired Guest OS or pressting CTRL + S key combination

b) Next step is to mount the Virtual CD Guest Additions inside the Guest OS VM

To mount the Virtual content provided by the just ticked VBOX "Insert Guest Additions CD" menu, inside the Guest OS Linux, you have to run simple mount command:

 

 

root@debian:~# mount /media/cdrom1
mount: /dev/sr1 is write-protected, mounting read-only

 

c) Install necessery packages that VBoxLinuxAdditions.run will use

Further on VBoxLinuxAdditions.run (additions script) that adds the integration between the Host operating system and the Guest OS depends on some essential tools necessery for building (compiling) / developing software on Linux, this are:

1.) build-essential – a meta package that will install the following set of packages:

 

dpkg-dev fakeroot g++ g++-6 libalgorithm-diff-perl libalgorithm-diff-xs-perl libalgorithm-merge-perl libdpkg-perl libfakeroot libfile-fcntllock-perl libstdc++-6-dev


which are necessery for creation .deb packages, compiling code and other various activitions. a) build-essential is a very important Debian based distro package and if you happen to be new to Linux or just starting learning how to develop programs on Linux, you will soon realize you will need it installed across almost all Linux OS hosts you maintain or develop on …

VirtualBox-VBoxLinuxAdditions-run-script-missing-headers-gcc-perl-how-to-fix

 

root@debian:~# apt-get install –yes build-essential linux-headers-$(uname -r) gcc perl make

 


2.) The linux-headers package in my case that it is is linux-headers-4.9.0-7-amd64 is important as it provides kernel header files that are necessery when compiling and integrating kernel modules VBoxLinuxAdditions.run script depends on it as it builds a kernel module that adds the integration (that enables Copy / Paste and performance inprovements) between the Host VM machine and Guest OS

3.) gcc perl packages this two provides the C compiler and perl scripting programming language interpreter which are also used by VBoxLinuxAdditions.run script.


Now run VBoxLinuxAdditions.run:

As you see in above screenshot the

root@debian:~#
root@debian:/media/cdrom1# sh VBoxLinuxAdditions.run
Verifying archive integrity… All good.
Uncompressing VirtualBox 5.2.18 Guest Additions for Linux……..
VirtualBox Guest Additions installer
Removing installed version 5.2.18 of VirtualBox Guest Additions…
Copying additional installer modules …
Installing additional modules …
VirtualBox Guest Additions: Building the VirtualBox Guest Additions kernel modules.  This may take a while.
VirtualBox Guest Additions: Running kernel modules will not be replaced until the system is restarted
VirtualBox Guest Additions: Starting.

 


If everything is fine you should get command output like above.

Above are the steps given to follow on current latest Debian Linux 9.5 (Stretch) as a Guest OS (this tutorial should be working also on Ubuntu / Mint and other deb package based distributions for RPM package based Linuxes Fedora / CentOS check out my previous toturial how to enable Linux Guest Virtualbox Addition on Redhat based distos.)

P. S.

What about Mac OS X since it is based on FreeBSD and it includes a lot of GNU licensing programs?

If you wonder whether on Mac OS X you don't need to run guest additions script such as (VBoxLinuxAdditions.run) on Mac Host -> Guest OS integration is done only by enabling the feature from VBox GUI interface via:
 

Devices -> Insert Guest Additions CD Image

What about enabling Copy / Paste on Linux Host VirtualBox hosting a Windows Guest OS?

 

 

Enabling Copy / Paste on a Windows Virtual Machine (I wrote about it earlier here), follows the same steps as in this tutorial.
The only difference is instead of running the VBoxLinuxAdditions.sh you have to navigate to the CD from Windows Explorer and run the appropriate .exe file depending on your architecture (X86 or 64 bit), the files to run on the virtual CDROM are one of the 3:

1. VBoxWindowsAdditions-amd64.exe
2. VBoxWindowsAdditions.exe
3. VBoxWindowsAdditions-x86.exe

Follow the click through interface and you will have the Copy / Paste between your Linux -> Windows OS working.

Happy Copy / Pasting ! 🙂

How to get a list and Backup (Save Enabled Plugins) / Restore Enabled (Active) plugins in WordPress site with SQL query

Wednesday, January 14th, 2015

get-list-and-backup-restore-enabled-active-plugins-only-in-wordpress-with-sql-mysql-query

Getting a snapshot of all active plugins and keeping it for future in case if you install some broken plugin and you have to renable all enabled plugins from scratch is precious thing in WordPress.

… It is really annoying when you decide to try to enable few new plugins and out of a sudden your WordPress site / blog starts hanging (when accessed in browser)…

To fix it you have to Disable All Plugins and Re-enable all that used to work. However if you don't keep a copy of the plugins which were previously working and you're like me and have 109 plugins installed of which only 50 are in (Active) state / used. It could take you a day or two until you come up with a similar list to the ones you previously used … Thanksfully there is some prevention you can take by dumping a list of all plugins that are currently active and in later time only enable those in the list.

 

# mysql -u root -p
Enter password:

mysql> USE blog_db;

Here is the output I get in the moment:
 

mysql> DESCRIBE wp_options;
+————–+———————+——+—–+———+—————-+
| Field        | Type                | Null | Key | Default | Extra          |
+————–+———————+——+—–+———+—————-+
| option_id    | bigint(20) unsigned | NO   | PRI | NULL    | auto_increment |
| option_name  | varchar(64)         | NO   | UNI |         |                |
| option_value | longtext            | NO   |     | NULL    |                |
| autoload     | varchar(20)         | NO   |     | yes     |                |
+————–+———————+——+—–+———+—————-+

 

mysql> SELECT * FROM wp_options WHERE option_name = 'active_plugins';

Copy and paste this CVS format data to a text file or a Word document for later reference ..

To restore back to normal only active WordPress plugins, first launch following SQL query to disable all enabled wordpress plugins:

UPDATE wp_options SET option_value = 'a:0:{}' WHERE option_name = 'active_plugins';

To restore above "backupped" list of active WP plugins you have to copy paste the saved content and paste it into above UPDATE query substituting option_value=' ' with the backupped string.

P.S. – This query should work on WordPress 3.x on older wordpress ver 2.x use instead:

UPDATE wp_options SET option_value = ' ' WHERE option_name = 'active_plugins';

Because pasting the backupped Active plugins list CSV is a messy and unreadable from command line it is recommended for clarity to use PHPMyAdmin frontend (whenever it is available) on server. This little hint is a real time-saver and saves a lot of headaches. Before proceeding to any Db UPDATE SQL queries always backup your Blog database, with time structure of WordPress data changes!, so in future releases this method might not be working, however if it helped you and works on your version please drop a comment with WordPress version on which this helped you.

Enjoy! 🙂

 

How to share your Windows local drives via Remote Desktop (RDP) – Safe file copy with RDP protocol

Tuesday, October 14th, 2014

remote-desktop-connection-options-button-screenshot

Just had a task to install Tomcat 7, Java JRE 1.7 and .NET Framework 3.5 and MS Visual C++ x86 on a Windows 2008 RC2 system situated behind a firewalled network NAT. To do the installation I had to use a special jump host (which was also a MS Windows system). The end system where installation had to occur did not have access to the Internet was in special DMZ-ed network so to install above 3 software packages I had to transfer them from my notebook to install host.
To depic what had to happen, I had to:

Transfer files from (host A – my notebook) -> via host (B – jump host) to host (C – the end install host).

Default Windows RDP Client command (mstsc.exe) supports transferring files between host A and RDP-ed host B via standard file copy / paste, so I tried transferring files between my work Windows PC to (jump host B), by copy pasting the files, but as the DotNetFx35Client.exe file was 261 Megabytes and the network between host A and B has some shapings and network firewalls the file transfer timed out. Copy / Paste method via RDP Protocol by default, doesn’t support Transfer Resume thus in order to transfer the 261 MB file, I tried Sharing C:Temp Folder and transfer that way, but unfortunately I didn’t have the permissions in that Windows Domain to create sharings (even though on the remote system I was already logged in with admin accounts). I’ve consulted a colleague on advise on how to transfer the files and I was told about a Win RDP client option to share drives.

Here is how to share your PC drive letters C: D: E: etc. via Remote Desktop Protocol


1. Run mstsc.exe

2. Click the Options button

remote-desktop-connection-options-button-screenshot

3. Click Local Resources tab

4. Click More button

remote-desktop-connection-more-options-button-screenshot

5. Click on Drives

remote-desktop-connection-share-windows-disk-drives-option-screenshot

Then after connecting to the Remote RDP host, all your local PC drive partitions C: D: E: will be visible as (attached) ones in mounted in My Computer / MS Explorer with assigned new drive letters

Once, I transferred the .NET Framework 3.5 while using the installer I was notified that .NET Framework 3.5 is by default included in Windows 8 and I need only to enable it.

To enable .NET Framework 3.5 in Windows 8 from Control Panel

Choose Programs, and then choose Turn Windows features on or off.

Select the .NET Framework 3.5 (includes .NET 2.0 and 3.0) check box.

Installing Virtualbox Guest Additions Vboxadditions on CentOS 7, Fedora 19 / 20 and RHEL 6.5 / 5.10 on Windows host

Virtualbox_guest_additions-on-centos-7-howto-virtualbox-logo
If you decided to use Redhat based Linux distribution inside Virtualbox Virtual Machine on Windows 7 / 8, first thing to do right after installing the Linux guest OS is to install Virtualbox Guest Additions. Earlier I've blogged How to enable virtualbox VM Windows XP fullscreen mode on Virtualbox running on Ubuntu now I need it vice versa a Linux OS living inside Virtual Machine running on top of Windows 7 Enterprise. need to enable Full-screen mode. Another reason why Vboxadditions should be installed right after Linux install is complete is for performance reasons and better integration between host OS and guest OS. Virtualbox Guest Additions enables mouse's copy / paste functions to work between Win and Virtualized Linux as well as enables arbitrary screen resolutions (resizing VM guest window) etc. On Windows versions of Virtualbox to install Vbox Guest Additions it is no longer necessery to download and mount a separate vbox-guest-additions ISO file, this is handled by Virtualbox itself.

The steps described here for installation of VirtualBox Guest Additions are tested and prooved as working on current latest CentOS 6.5, however they should be working (with or without minor modifications) in rest of RPM based Linux distributions

Fedora 20, 19, 18, 17, 16, 15, 14, 13, 12, CentOS 6.5, 6.4, 6.3, 6.2, 6.1, 6.0, 5.10 and Redhat Enterprise Linux (RHEL) 6.5, 6.4, 6.3, 6.2, 6.1, 6, 5.10 VirtualBox version installed on Windows 7 host is 4.3.14 build.

 

Devices -> Drag'n'Drop (Bidirectional)

Devices -> Share Clipboard (Bidirectional)


1. Installing VirtualBox GuestAdditions on CentOS 7, Redhat, Fedora

a) become superuser

su root
[root@centos~:]#

b) Mount Virtualbox provided Guest additions into virtual cdrom /dev/cdrom

From VirtualBox click on
 

Devices -> Install Guest Additions

centos7-install-guest-additions-cd-screenshot-microsoft-windows-virtualbox

mkdir /media/VirtualBoxGuestAdditions
mount -r /dev/cdrom /media/VirtualBoxGuestAdditions

c) Update to the latest Linux kernel with yum

yum -y update kernel*

Then to boot up into the updated kernel – restart the system

shutdown -r now


d) Install Kernel headers bzip dkms bzip2

yum install -y gcc kernel-devel kernel-headers dkms make bzip2 perl

If you're installing VirtualBox Guest Additions on CentOS 6 or RHEL 5, you will have to install also below 2 rpms:
 

## CentOS 6 and Red Hat (RHEL) 5 ##
rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
 
## CentOS 5 and Red Hat (RHEL) 5 ##
rpm -Uvh http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm

 


e) export KERN_DIR to just installed kernel source

 

For CentOS 7 export following KERN_DIR

 

## Current running kernel on Fedora, CentOS 7 and Red Hat (RHEL) 7 ##
KERN_DIR=/usr/src/kernels/`uname -r`
export KERN_DIR

For older CentOS and RHEL 5 export
## Current running kernel on CentOS 5 and Red Hat (RHEL) 5 ##

KERN_DIR=/usr/src/kernels/`uname -r`-`uname -m`
export KERN_DIR

f) Download VBoxAdditions 4.3.14 iso from Virtualbox website

I've made mirror of VBoxGuestAdditions_4.3.14.iso for download here:
 

mkdir /usr/share/virtualbox
cd /usr/share/virtualbox

wget http://dlc.sun.com.edgesuite.net/virtualbox/4.3.14/VBoxGuestAdditions_4.3.14.iso

g) Mount the iso
 

mount -t iso9660 VBoxGuestAdditions_4.3.14.iso /media/VirtualBoxGuestAdditions/


h) Compile and Install Virtualbox GuestAdditions kernel modules
For both 32-bit and 64-bit systems run one and the same shell script:

cd /media/VirtualBoxGuestAdditions
./VBoxLinuxAdditions.run

Verifying archive integrity… All good.

Install VMWare tools on Debian and Ubuntu Linux – Enable VMWare Fullscreen and copy paste between OS host and Virtual machine

Wednesday, May 28th, 2014

install-vmware-tools-on-debian-gnu-linux-and-ubuntu-howto

If you need to use Virtual Machine to run some testing on heterogenous Operating Systems and you have chosen VMWare as a Virtual Machine. You will soon notice some of Virtual Machines functionality like copy between host operating system and Virtual Machine, true fullscreen mode and most importantly Copy paste between your host operating system and VMWare is not working. I'm not too much into Virtualization these days so for me it was truely shocking that a proprietary software like VMWare, claimed to be the best and most efficient Virtual Machine nowadays is not supporting copy / paste, fullscreen and copy between host and guest OS.  For those arguing why I'm using VMWare at all as it is proprietary and there is already free software Virtual Machines like QEMU and Oracle's VirtualBox its simply because now I have the chance to install and use VMWare 9 Enterprise on my work place at HP with a free Corporate license – in other words I'm using VMWare just for the sake of educating myself and would always recommend VirtualBox for those looking for good substitute free alternative to VMWare.

Before trying out VMWare, I tried Virtualbox to emulate Linux on my HP work PC running Windows with VirtualBox I was having issues with keyboard not working (because of lack of support of USB, no full screen support and lack of copy / paste between OS-es), I've just recently understood this is not because Virtualbox is bad Virtualization solution but because I forgot to install VirtualBox Oracle VM VirtualBox Extension Pack which allows support for USB, enables copy paste and full screen support. The equivalent to Virtualbox Oracle VM VirtualBox in VMWare world is called VMWare-Tools and once the guest operating system is installed inside VMWare VM, its necessary to install vmware-tools to enable better screen resolution and copy paste.
 

In Windows Virtual Machine installation of vmware-tools is pretty straight forward you go through VMWare's menus

 

VM -> Install Vmware-tools

install-vmware-tools-on-linux-guest-host-os-debian-redhat-screenshot

follow the instructions and you're done, however as always installing VMWare-tools on Linux is little bit more complicated you need to run few commands from Linux installed inside the Virtual Machine to install vmware-tools. Here is how vmware-tools is installed on Debian / Ubuntu / Linux Mint and rest of Debian based operating systems:

  1. Install Build essentials and gcc You need to have this installed some developer tools as well as GCC compiler in order for the vmware-tools to compile a special Linux kernel module which enables extra support (integration) between the VMWare VM and the installed inside VM Linux distro

apt-get install --yes build-essential gcc
...

2. Install appropriate Linux headers corresponding to current Linux OS installed kernel

apt-get install --yes linux-headers-$(uname -r)
....

3. Mount CD (Virtual) Content to obtain the vmware-tools version for your Linux

Be sure to have first checked from VMWare menus on menus VM -> Intall Vmware Tools
This step is a little bit strange but just do it without too much questioning …


mount /dev/cdrom /mnt/
umount /media/cdrom0/
mount /media/cdrom
mount /dev/sr0 /mnt/cdrom/
mount /dev/sr0 /mnt/

 

Note that /dev/sr0, might already be mounted and sometimes it might be necessary to unmount it first (don't remember exactly if I unmounted it or not)

4. Copy and Untar VMwareTools-9.2.0-799703.tar.gz

cp -rpf /media/cdrom/VMwareTools-9.2.0-799703.tar.gz /tmp/
cd /tmp/
tar -zxvvf VMwareTools-9.2.0-799703.tar.gz
...

5. Run vmware-tools installer

cd vmware-tools-distrib/
./vmware-install.pl

You will be asked multiple questions you can safely press enter to answer with default settings to all settings, hopefully if all runs okay this will make VMWare Tools installed

You can now run VMware Tools by invoking "/usr/bin/vmware-toolbox-cmd" from the
command line or by invoking "/usr/bin/vmware-toolbox" from the command line
during an X server session.
To enable advanced X features (e.g., guest resolution fit, drag and drop, and
file and text copy/paste), you will need to do one (or more) of the following:
1. Manually start /usr/bin/vmware-user
2. Log out and log back into your desktop session; and,
3. Restart your X session.

Found VMware Tools CDROM mounted at /mnt. Ejecting device /dev/sr0 …

.To make sure vmware-tools compiled modules are loaded into Linux kernel inside VM, restart the Virtual Machine. Once Linux boots again and you login to gnome-terminal to check what is vmware-tools status (e.g. if properly loaded) run:

service vmware-tools status
vmtoolsd is running

install-vmware-tools-on-debian-gnu-linux-and-ubuntu-virtual-machine-screenshot

This method of installing works on Debian 7 (Wheezy) but same steps should work on any Ubuntu and rest of Debian derivatives. For Redhat (RPM) based Linux distributions to install vmware-tools after mounting cdrom drive following above instructions you will have an rpm package instead of .tar.gz archive so all you have to do is install the rpm, e.g. launch smth. like:

rpm -Uhv /mnt/cdrom/VMwareTools-9.2.0-799703.i386.rpm

How to set a crontab to execute commands on a seconds time interval on GNU / Linux and FreeBSD

crontab-execute-cron-jobs-every-second-on-linux-cron-logo
Have you ever been in need to execute some commands scheduled via a crontab, every let’s say 5 seconds?, naturally this is not possible with crontab, however adding a small shell script to loop and execute a command or commands every 5 seconds and setting it up to execute once in a minute through crontab makes this possible.
Here is an example shell script that does execute commands every 5 seconds:

#!/bin/bash
command1_to_exec='/bin/ls';
command2_to_exec='/bin/pwd';
for i in $(echo 1 2 3 4 5 6 7 8 9 10 11); do
sleep 5;
$command1_to_exec; $command2_to_exec;
done

This script will issue a sleep every 5 seconds and execute the two commands defined as $command1_to_exec and $command2_to_exec

Copy paste the script to a file or fetch exec_every_5_secs_cmds.sh from here

The script can easily be modified to execute on any seconds interval delay, the record to put on cron to use with this script should look something like:

# echo '* * * * * /path/to/exec_every_5_secs_cmds.sh' | crontab -

Where of course /path/to/exec_every_5_secs_cmds.sh needs to be modified to a proper script name and path location.

Another way to do the on a number of seconds program / command schedule without using cron at all is setting up an endless loop to run/refresh via /etc/inittab with a number of predefined commands inside. An example endless loop script to run via inittab would look something like:

while [ 1 ]; do
/bin/ls
sleep 5;
done

To run the above sample never ending script using inittab, one needs to add to the end of inittab, some line like:

mine:234:respawn:/path/to/script_name.sh

A quick way to add the line from consone would be with echo:

echo 'mine:234:respawn:/path/to/script' >> /etc/inittab

Of course the proper paths, should be put in:

Then to load up the newly added inittab line, inittab needs to be reloaded with cmd:

# init q

I've also red, some other methods suggested to run programs on a periodic seconds basis using just cron, what I found in stackoverflow.com's  as a thread proposed as a solution is:

* * * * * /foo/bar/your_script
* * * * * sleep 15; /foo/bar/your_script
* * * * * sleep 30; /foo/bar/your_script
* * * * * sleep 45; /foo/bar/your_script

One guy, even suggested a shorted way with cron:

0/15 * * * * * /path/to/my/script
