- Secure connection to VMs through Virtual Machine ManagerI don't recommend it for Workstations, but here is the info.Install ssh in the server (vgui, running Debian Squeeze) and the backup server (foobar)Check the ips constantly.As per the user to access the Virtual Manager is xcapncrunchx create the authentication forxcapncrunchxInstall ssh:References:Guide: SSH Secure ShellStup the firewall ports accordingly:References:See guide: NetfilterNote: It is mandatory to use the default SSH port, 22 for remote hosts, and some services andprograms to work correctly. Check port availability, configuration and usage with netfilter, netstat andwhat is in the file /etc/services. See also the respective programs guides.Automatic public key authentication. The authentication with a public key also is required for our objectives, is specially used specialto execute local scripts in a remote machine without pass phrase typing in user command prompts. Asfollows: <1> The server and the backup-server had being accessed remotely, because the ssh directorieswe need are created while servers ssh was being configured, otherwise we do not have that dirs towork. After a process like that, restart the ssh service with the command sh> /etc/init.d/ssh restart.Enter to the server machine remotely or locally. <2> In the server machine go to the ssh directory. It is in the 'user-name' directory.sh> cd /home/esteban/.shh/ <3> Generation of the new public and private key.sh> ssh-keygen -t dsa For old systems or ssh programs using the RSA algorithm instead of the DSA, use this othercommand:sh> ssh-keygen -t rsa

For DSA and RSA while the new key is being created the system will ask you where to put thenew keys, then press ENTER key. When the system asks for a password press ENTER key again. Wedon't need the password because we want an automatically 'ssh' communication, with typingpasswords, for our script, that we are preparing. In other stages this password can be needed, but notnow. <4> Verify the new key is on our relative directory. There are two new keys, the key and key.pubwith their default names: id_dsa.pub and id_dsa.sh> ls <5> Send the public key (key.pub) to the /home/user directory in the backup-server. Sincethe ./ssh directory (where we are)sh> scp -P 49 id_dsa.pub esteban@backup-server-IP-adress-or-FQDN:~ The scp program going to show the public key was recorded in the backup-server. The -P optionmeans the ssh port we are listen in both machines. That port was configured during the section “Hostscommunication security enforce topics”. <6> Backup and Edit the ssh configuration's file in the server:sh> cp /etc/ssh/sshd_config /etc/ssh/sshd_configBAKsh> vim /etc/ssh/sshd_config Quit the '#' to the lines #AuthorizedKeysFile, and #%h/.ssh/authorized_keys. <6> In the backup-server machine, look for the public key we recently added to the userdirectory:sh> cd /home/esteban/.sshsh> ls <7> Add the public key to the authorized_keys file, is in the user directory in the backup server.sh> cat id_dsa.pub>.ssh/authorized_keys For other scenarios we can add more keys using 'cat file.pub >> authorized_keys ', to have allkeys in the same file. Keys are function like registered IDs to enter to a building. <8> Restart the ssh service.

sh> /etc/init.d/ssh restart <9> Go back to the server machine and try to enter to the backup-server by type, from it and asuser esteban to avoid errors:sh> ssh -2 esteban@backup-serverIP-or-FQDN -p 49 The number '2' in the command, determines the use of the version 2 of the ssh protocol,esteban is the user who access using the new key, the part next to @ may be 192.168.1.40, and -p 49defines the ssh port (do not use 22) to enter to the backup-server creating an unknown VPN. That portwas previously configured in the section “Hosts communication security enforce topics”. In case of weare using an incorrect port we are going to receive the message: “Connection Refused”. If the configuration and the public key are working, we will see the prompt of the backup-serverat this point. Note: For use other key file we can add an “i” to the command, specifying the path that publickey.sh> ssh -2 -i /etc/ssh/key2.pub esteban@backup-serverIP-or-FQDN -p 49 Check where is the key in the remote machine. <10> Do the same process of authentication using public keys, but thinking the server is thebackup-server and backup sever is the server, because our script to backup the server needs to send'rsync' commands from one machine to other thorugh the ssh VPN tunnel. Note: There is another ssh in the market called ssh2 but we are not using it. Note: SSH combined in the way described here with the program 'sudo' can be used to executeroot commands in a remote systems. Sudo is described in the section “Sudo to give root commands tousers”VirtualBoxUse VirtualBox to virtualize OSX Snow Leopard, Windows, DOS, Linux, BSD, etc.I searched for it for Jessie in the Debian repos Web site.I need to add the \"contrib\" repos to the default configuration to be able to install the program.References:https://www.debian.org/distrib/packagesWeb: https://packages.debian.org/jessie/virtualbox

To test 3D games:Before installing and make work a 3D game to test the virtualization of the Video card with 3Dacceleration, you got to install virtualbox guest additions. I can't certificate that the VMware machinegames are going to work under Linux after the pass from VirtualBox for Windows to VirtualBox forLinux, due to the virtual drivers used during the system installation. I experienced similar problemsbetween VMware versions due to the network card was incompatible in the new Virtual ApplianceMachine. If everything is set up and the games fail you'd better create a new VM from scratch andreinstall the games on it.Install virtualbox guest additions on Linux:

Reference:Web: http://www.binarytides.com/virtualbox-guest-additions-debian-wheezy/File: virtualbox guest additions.pdfSteps:Click the About menu in VirtualBox to check the program version.The current version is: 4.3.18.I search \"virtualbox-guest-additions-iso\" in the Debian packages repository and the Web returns amessage that says:You have searched for paths that end with virtualbox-guest-additions-iso in suite jessie, all sections,and all architectures.Sorry, your search gave no resultsThe package tracker: https://tracker.debian.org/pkg/virtualbox-guest-additions-isohas the next news at the top:[2015-05-25] Accepted virtualbox-guest-additions-iso 4.3.28-1 (source all) into unstable (Ritesh RajSarraf)[2015-05-05] virtualbox-guest-additions-iso 4.3.26-2 MIGRATED to testing (Britney)[2015-04-30] Accepted virtualbox-guest-additions-iso 4.3.26-2 (source all) into unstable (Ritesh RajSarraf)[2015-04-01] virtualbox-guest-additions-iso 4.3.18-3 MIGRATED to testing (Britney)[2015-03-26] Accepted virtualbox-guest-additions-iso 4.3.18-3 (source all) into unstable (Ritesh RajSarraf)[2015-03-21] virtualbox-guest-additions-iso REMOVED from testing (Britney)[2015-03-18] Accepted virtualbox-guest-additions-iso 4.3.26-1 (source all) into experimental (RiteshRaj Sarraf)[2015-03-14] Accepted virtualbox-guest-additions-iso 4.3.18-2 (source all) into unstable (Ritesh RajSarraf)[2015-03-04] Accepted virtualbox-guest-additions-iso 4.3.24-1 (source all) into experimental (RiteshRaj Sarraf)[2015-02-14] Accepted virtualbox-guest-additions-iso 4.3.22-1 (source all) into experimental (RiteshRaj Sarraf)[2014-12-04] Accepted virtualbox-guest-additions-iso 4.3.20-1 (source all) into experimental (RiteshRaj Sarraf)[2014-10-29] virtualbox-guest-additions-iso 4.3.18-1 MIGRATED to testing (Britney)Let's take a look at the line:[2015-03-26] Accepted virtualbox-guest-additions-iso 4.3.18-3 (source all) into unstable (Ritesh RajSarraf)It says that the version 4.3.18-3 of the ISO is in the \"unstable\" repository.

I click on the link and it takes me to the main acceptance message. In summary in the body I read thereason why the package is \"unstable\", due to: \"* Conflict with upstream proprietary packages 4.3series...\", ... and we must wait for the Virtual Box team to debug the issue.I go back to search again the package as UNSTABLE in the Debian Web, here:https://www.debian.org/distrib/packagesAnd the results show the package in the sid repo:https://packages.debian.org/search?keywords=virtualbox-guest-additions-iso&searchon=names&suite=unstable&section=allWhen I enter to the description to check the package description, i note that the packagerecommends to use another version of VirtualBox, here:https://packages.debian.org/sid/virtualbox-guest-additions-iso\"Other Packages Related to virtualbox-guest-additions-iso rec: virtualbox (>= 4.3.28) x86 virtualization solution - base binaries\"I click to see the VirtualBox version and the site takes me to:https://packages.debian.org/sid/virtualboxIn conclusion, I have nothing to loose but perhaps stability, installing the new VirtualBox version. I alsohave to consider the new dependencies the new VirtualBox version could require.First, I would try to install the package virtualbox-guest-additions-iso 4.3.18-3, and if the installationfails, install the new VirtualBox from sid.To setup sid in Debian Jessie:Select a code mirror from the list, add the new lines to the sources file:$ sudo nano /etc/apt/sources.list# Sid mirror in North America# Packages: virtualbox-guest-additions-iso 4.3.18-3,deb http://ftp.us.debian.org/debian sid main non-freeSave changes and install the package:$ sudo apt-get update$ sudo apt-get install virtualbox-guest-additions-isoOutput:Reading package lists...

However I still need an ISO to install onthe guest operating systems, for example Windows XP.In the same page of the page of the Official repo, which has the title:\"Package: virtualbox-guest-additions-iso (4.3.28-1) [non-free]\"I find a link to all the files: \" [list of files] \", I click on the page and it shows me the location of the filesafter the installation:/usr/share/doc/virtualbox-guest-additions-iso/changelog.Debian.gz/usr/share/doc/virtualbox-guest-additions-iso/copyright/usr/share/virtualbox/VBoxGuestAdditions.isoThe third file is the ISO itself. I save a copy in my personal repo directory and remember the location toinstall it on the guest VM OS.In case of MS Windos XP, the system is going to ask you to install the additions in safe mode. To restartthe system in safe mode reboot during the boot up press F8.Issues:VirtualBox Guest additions service doesn't want to start, so I am unable to attach USB devices to thevirtual machine:$ sudo systemctlOutput extract: loaded failed failed LSB: VirtualBox Additions service● vboxadd-service.service

If you want more information on systemd, look for my systemdguide.However, I went ahead documenting the steps to use every VirtualBox feature, and hope to see thisissue resolved as soon as possible. Anyway remember that VirtualBox is not the only Virtualizationsolution. BTW, KVM is my first option.Steps to install Extension Packs:To verify the extension packs installed:$ sudo vboxmanage list extpacksOutput:Extension Packs: 1Pack no. 0: VNCVersion: 4.3.18Revision: 96516Edition:Description: VNC plugin moduleVRDE Module: VBoxVNCUsable: trueWhy unusable:End of Output.The Output shows only the pack VNC, to access virtual machines desktops remotely. But we requirethe Extension Pack to attach USB devices to the Virtual Machine.The Extension Pack cannot be downloaded from the Debian Official repo, include \"main\" \"contrib\" aswe did with VirtualBox. Take a look at the configuration file: /etc/apt/sources.list.$ apt-cache search 'virtualBox'You have to download the Extension Pack matching the current VirtualBox version installed. To see theversion open VirtualBox and then go to the section \"About\", or use:

$ man vboxmanage$ vbox manage -vOutput:4.3.18_Debianr96516End of Output.I find out the file Oracle_VM_VirtualBox_Extension_Pack-4.3.18-96516.vbox-extpack, to all platforms,in the section (old builds), in the Official VirtualBox downloads Web site.References:Web: https://www.virtualbox.org/wiki/Download_Old_Builds_4_3_pre24File: Find out compatible extension pack.pdfGo to the Downloads diretory and install the Pack by typing:$ sudo vboxmanage extpack install Oracle_VM_VirtualBox_Extension_Pack-4.3.18-96516.vbox-extpackOutput:0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%Successfully installed \"Oracle VM VirtualBox Extension Pack\".esteban@ProLiant:~/Downloads/Debian 8 Jessie repo/VirtualBox 4.3.18 Extension PackEnd of Output.Verify the installation:$ sudo vboxmanage list extpacksReferences:Web: http://www.itzgeek.com/how-tos/mini-howtos/how-to-install-virtualbox-extension.htmlFile: How to install VirtualBox Extension Pack.pdfWeb: https://forums.virtualbox.org/viewtopic.php?f=7&t=44337File: Console Extension Pack installation.pdfSomething important about USB Flash drives:I don't recommend the usage of the USB, mostly because the USB ports can transfer viruses betweenthe Virtual machine and our the Development Desktop. Either way, sometimes we could need to add aFlash drive or a Hard drive to any Virtual Machine, and if so, try to prevent the security riskspotentially associated to this operation, for example having an updated active flash drive connectionantivirus like Kaspersky in the virtual machine.Next are the instructions to get USB working on Virtual Machines:Issues:Open Virtual Box and set up your Virtual Machine to accept USB attached to your Linux Box. (Checkthe two USB check boxes, and choose what drive to attach since Linux).It is supposed that the next step is Open the Virtual Machine and accept the connection.The problem seems the remaining issue with the Guest Additions, the cause seems is not theExtension Packs.

The real problem behind the Guest Additions and the Extension Packs issues:I required to open an encrypted External USB Hard drive that I have.The hard drive encryption program has not Linux version to allow access to the HD data.Solution 1:Mount the hard drive normally.Next, I open a Windows virtual machine and enter the encryption password in WindowsNext, I dettach the hard drive drive from Windows to let Linux re-take the control of the decryptedhard drive.Failure: Guest Additions and Extension Packs issues don't allow the VM to read the HD content.Solution 2:I mounted the HD (hard drive) on /media/cdrom0 as a network folder since VirtualBox configuration,auto-monted and Full access permissions was set to active, but once in Windows VM I can only readhtml files due to the encryption file .exe. Executable files like the program which asks for the passwordto decrypt the hard drive content are inaccessible this way.References:Pictures:(Pending)Solution 3:One solution is to have different Hds to every system, NTFS HDs for Windows and EXT4 HDs for Linux,but unfortunately, I don't have more HDs.Solution 4:One solution is to install Wine and attempt to run the Windows executable of the program to decryptthe content of the HD. I did it but the HDs' encryption software is not supported by Wine.Solution 5 (What is actually going on):I Decrypted the most of the hard drive, keeping the secret files under VeraCrypt directories. I can onlycreate share directories from the VM with accesses from the network machines, and create sharedirectories in the virtualization server machine with access from the VMs.References:Topic: Encrypt External HD Drive you will share with Windows.Guide: VeracryptTopic: Encrypt USB drivesGuide: LUKSTopic: Share directories in the virtualization server machine with access from the VMs.Guide: Share system directories across the networkInstall a new Machine with Windows XP SP2:

The network configuration is:Adapter 1:Bridged adapter: br0To be able to pass through the only network NIC from Virtual Machines to the network using werequire to Bridge the Ethernet networking. To create this bridge you have to pause this guide and goto read the sections \"- Bridge the Ethernet networking\" and \"- Bridge the Wireless networking\" of theguide \"Basic Networking\" (LINK).Allow AllCable connected.Share /home/esteban in the VM configuration.After the installation I share a folder from the XP machine no the local area network (LAN):Add the machine to the workgroup WORKGROUP.Activate the option to share folders and printers and don't choose to create the network clientinstallation disc.Paste the folder into the the shared directory.Right click and share with write access from the rest of users in the network.When the shared is ready on windows and you see the network folder, simply go to Nautilus andaccess the network, you don't need to install samba or other software.Send photoshop CS3 with Bridge and CS4 to the shared folder from Nautilus and install the programs.Set the option to Show files extensions in the file explorer.Back-up the Virtual Machine:Use the VirtualBox cloning tool to CLONE a copy of the VM on the WD HD. Don't copy and paste VMsto save statuses like instances or snapshots because every VM has a UUID and then if you don't clonewhen you attempt to re-open it in another place is not going to work.More Virtualbox Tricks:Reference:Topic: 10 VirtualBox Tricks and Advanced Features You Should Know About.Web: http://www.howtogeek.com/171228/10-virtualbox-tricks-and-advanced-features-you-should-know-about/File: 10 virtualbox tricks and advanced features.pdfDrag and Drop is not working:Web: http://askubuntu.com/questions/575056/bidirectional-dragn-drop-is-not-working-with-virtualbox-and-ubuntu-14-04File: Bidirectional drag'n drop is not working with VirtualBox and ubuntu 14.pdfLearn to install web development software for the MacOSRubyNotes:

It's not a problem to have a version running because it is possible to install differentversions and switch them as we did with Java, to work on different projects at the same time.Remember that the Mac computers come with a working version of Ruby out of the box. In Debian, Irecommend you to install the default version which comes with the system, but if you require you areable to install a variant. The current status of the official repos on the Debian Official Web site showshow there is not any program to switch from one variant to another (update-alternatives) because thecurrent variants are unfinished and are considered as experimental packages you can download ansinstall at your own risk.References:Available interpreters in Debian 8 (jessie):MRI 2.1.5 ruby2.1JRuby 1.5.6 jrubyAs there are no (MRI) alternatives to choose from, update-alternatives support has been removed.(Longer explanation about the alternatives removal can be found here:https://lists.debian.org/debian-ruby/2014/03/msg00077.html and here:https://lists.debian.org/debian-project/2014/02/msg00028.html )Reference:Web: https://wiki.debian.org/RubyFile: Ruby Debian Wiki.pdfDisplays the list of ruby files after the K Desktop Environment installation:$ dpkg -l | grep 'ruby'Output: 4:4.11.3-4.1 amd64 internal library for Qt 4 Rubyii libqtruby4shared2bindings

PoorWindows users must uninstall and re-install manually the AVAILABLE, new as possible .exe programversion.You know Linuxbrew is not the only repo source you need to complete your Development project; Iam going to add Ruby, NPM, Grunt, some Git sources and, last but not least, APT. Sometimes youshould decide between two sources to install from. In those cases match the advantages and thedisadvantages of every one, like interactions, dependencies and versions before you take the finaldecision on what to install and use.In summary search:

For Formulas, on LinuxBrewFor packages, on NPMFor packages, on BowerFor gems, on RubyFor contribs, on GruntFor sources, on GitFor system apps, on APTInstallation of dependencies:Ruby:I believe the best way to start from is to take the advantage of the existing Ruby on the system toinstall LinuxBrew and deal with the Ruby versioning later.Curl:I also decided to use it with Ruby, because Curl has the option \"l\" which is Wget unavailable. Curl is onmy system since the installation of Conky, and seems LinuxBrew installable, but I can't install it fromLinuxBrew no LinuxBrew on the system yet. You can choose to install Curl from APT, just because theprogram is not required to Develop, and I am not developing yet. I can try to install Curl fromLinuxBrew after the installation of LinuxBrew.Reference:Web: http://braumeister.org/formula/curlTo install Curl from the Official Debian sources:$ sudo nano /etc/apt/sources.list$ sudo apt-get update$ sudo apt-get install curlGit:This has not been used yet. At first I wanted to install it later from LinuxBrew to preserve the Maccompatibility, but later on realized that I need it as dependency to get done the LinuxBrew installationno matter if I install from Ruby or Git repos.Steps:$ sudo apt-get update$ sudo apt-get install build-essential curl git m4 ruby texinfo libbz2-dev libcurl4-openssl-dev libexpat-dev libncurses-dev zlib1g-devOutput:Reading package lists...
