Install OpenSSH Server on Ubuntu

I’ve discussed the use of SSH in several posts in the past, but while recently building a new environment, I realized that I’ve never indicated how the service itself should be installed.

INSTALLATION:

sudo apt-get install openssh-server

If you desire to change any of the default configuration such as port or cyphers…


sudo vi /etc/ssh/ssh_config

NOTE: If you intend to access the server from the Internet, you will have to verify that port forwarding is enabled on your routers and firewalls.

Installing Tor Client on Ubuntu

The use of Tor software to hide your network activity occasionally comes up in the main stream news media as being only for illegal purposes such as drugs or pornography. There are however many instances where individuals or groups rely upon their activity being hidden from prying eyes. Examples are… Journalists, politicians and even common citizens that don’t want to have their personal information gathered and shared/sold.

Installing the client software is easy for most platforms. You can download and verify the signatures from the Tor website to be absolutely certain. If you trust the maintainers of the Ubuntu PPA’s or other compilations, you can also do so… (with appropriate precautions):

INSTALLATION:

sudo add-apt-repository ppa:webupd8team/tor-browser
sudo apt-get update
sudo apt-get install tor-browser

LinSSID

If you have ever used the popular software InSSIDer on Windows or OS/X, you might wonder if there is an equivalent application for Ubuntu/Linux.

LinSSID allows you to visually survey the Wifi networks in your area, identifying networks using the same channel as your own, even if they are not broadcasting SSID’s.


sudo add-apt-repository ppa:wseverin/ppa
sudo apt-get update
sudo apt-get install linssid

— OR —

sudo vi /etc/apt/sources.list
deb http://ppa.launchpad.net/wseverin/ppa/ubuntu YOUR_UBUNTU_VERSION_HERE main

NOTE: it seems that the release version is only available for ‘precise’ and has not been updated for newer Ubuntu releases, I was able to simply go to the terminal and execute "software-properties-gtk" to change ‘trusty’ to ‘precise’ on the PPA and it worked great!

Install Netflix on Ubuntu via Wine

UPDATE: (Sept. 2014) – Netflix will soon natively support Ubuntu, there are only a few small hurdles remaining, likely to be resolved by the NSS update expected in Ubuntu 14.10 (Utopic). A workaround is available for the impatient… http://www.omgubuntu.co.uk/2014/08/netflix-linux-html5-support-plugins.

For various reasons primarily related to DRM, there is not a native Ubuntu/Linux viewer for Netflix… this is one of the cases where WINE can help you out by providing (not emulating) a Windows environment.

These commands are for the Ubuntu setup, similar steps for other Linux distributions are available in the references.

I’ve found that it is better to pre-install the Wine Gecko and Wine Mono packages on Ubuntu.


sudo apt-get install wine-gecko
sudo apt-get install wine-mono

Then…

sudo apt-add-repository ppa:ehoover/compholio
sudo apt-get update
sudo apt-get install netflix-desktop

If you’ve never used WINE before within your Ubuntu/Linux environment, you’ll likely need to let it download the extensions for Windows, I believe that it will request to download and install the Gecko and Mono packages described above, click "Yes" if asked and all should go well!

Name based virtual hosting with Apache2 on Ubuntu

I often find it necessary to setup a temporary server for testing web applications. The easiest way to support this is often to create an integration (beta) test server that can be configured to support multiple hosts.

Initial Installation:

sudo apt-get install apache2
sudo a2enmod proxy
sudo a2enmod proxy_http
sudo a2enmod rewrite
sudo chmod 755 /var/www

To add a new site:

cd /etc/apache2/sites-available
sudo cp 000-default.conf yourdomain.com.conf
sudo vi yourdomain.com.conf
(change values as appropriate)
sudo chown -R YOURUSER:YOURGROUP yourdomain.com.conf
sudo mkdir -p /var/www/yourdomain.com
sudo chmod 755 /var/www
sudo vi /var/www/yourdomain.com/index.html
(add some fluff)
sudo chown -R YOURUSER:YOURGROUP /var/www/yourdomain.com
sudo a2ensite yourdomain.com
sudo service apache2 reload
sudo service apache2 restart

NOTE: replace YOURUSER and YOURGROUP with appropriate values for your server.

Install Plex Media Server on Ubuntu

You can find the latest release listed here and either download the file to your server directly or use the path to update the wget in the commands listed below…
https://plexapp.zendesk.com/hc/en-us/articles/201181647-Plex-Media-Server-Linux-nix-

Pre-requisite, you need to have avahi installed first or the script will later prompt you to do so…
sudo apt-get install avahi-daemon

i386 install:
wget -c downloads.plexapp.com/plex-media-server/0.9.8.18.290-11b7fdd/plexmediaserver_0.9.8.18.290-11b7fdd_i386.deb
sudo dpkg -i plexmediaserver_0.9.8.18.290-11b7fdd_i386.deb

amd64 install:
wget -c downloads.plexapp.com/plex-media-server/0.9.8.18.290-11b7fdd/plexmediaserver_0.9.8.18.290-11b7fdd_amd64.deb
sudo dpkg -i plexmediaserver_0.9.8.18.290-11b7fdd_amd64.deb

Then a series of commands, they should all be relatively straight forward. As the installer creates and runs the software under a user named ‘plex’, I create the user folders and change the default password in these steps… do what you are comfortable with!

sudo apt-get -f install
sudo mkdir /home/plex
sudo mkdir /home/plex/Music
sudo mkdir /home/plex/Videos
cd /home/plex
sudo chown plex * -R
sudo chmod 777 * -R
sudo passwd plex

Now you should be able to access the app with your browser, change the IP if you are not on localhost.
http://{ip}:32400/manage/index.html

WARNING: An installation using these steps could leave your server open to the general public, you
will want to password protect your server to secure any sensitive content, I’ll leave that for a separate topic.

Install Docky on Ubuntu Linux

One of the most immediate differences that typical computers notice between an Apple and other operating systems is the Dock Bar. This is a possible addition to any operating system (such as Windows or Linux). On Ubuntu Linux you can easily install Docky in just a few minutes.

sudo add-apt-repository ppa:docky-core/ppa
sudo apt-get install docky

Install SonarQube for Continous Inspection

Installation of Sonar requires but a few simple steps, though they can be rather obscure to many developers.

Connect to MySQL:

  1. CREATE DATABASE sonar CHARACTER SET utf8 COLLATE utf8_general_ci;
  2. grant all privileges on sonar.* to 'sonar@localhost' identified by 'sonar';
  3. flush privileges;

Easiest method, if you are on Ubuntu:

  1. sudo vi /etc/apt/sources.list
  2. Then add the following line:
    deb http://downloads.sourceforge.net/project/sonar-pkg/deb binary/
  3. sudo apt-get update
  4. sudo apt-get install sonar
  5. You will then have to stop/start as above to edit the configuration, generally to change database config:
    sudo vi /opt/sonar/conf/sonar.properties

Manual installation (and upgrade?) if you prefer to do things the hard way 🙂

  1. Download and unzip the release:
    wget http://dist.sonar.codehaus.org/sonar-3.6.1.zip
    unzip sonar-3.6.1.zip
    sudo mv sonar-3.6.1 /opt/sonar
    sudo rm -r /opt/sonar (to remove old link)
    sudo ln -s /opt/sonar-3.6.1/ /opt/sonar
  2. cd /opt/sonar/conf
  3. vi sonar.properties
    (uncomment lines for MySQL, comment out H2)
  4. sudo cp /opt/sonar/bin/linux-x86-64/sonar.sh /etc/init.d/sonar
  5. sudo vi /etc/init.d/sonar
    add the following 2 lines:
    SONAR_HOME=/opt/sonar
    PLATFORM=linux-x86-64

    change:
    WRAPPER_CMD="${SONAR_HOME}/bin/${PLATFORM}/wrapper"
    WRAPPER_CONF="${SONAR_HOME}/conf/wrapper.conf"
    PIDDIR="/var/run"

  6. sudo update-rc.d -f sonar remove
  7. sudo chmod 755 /etc/init.d/sonar
  8. sudo update-rc.d sonar defaults
  9. /etc/init.d/sonar start

Upgrades can be a little odd, if you see the maintenance page at http://localhost:9000/maintenance, go to http://localhost:9000/setup and do the required steps.

Install MySQL database on Ubuntu and add new user.

Installing MySQL on Ubuntu requires only a few simple steps.

  1. sudo apt-get install mysql-server
  2. sudo netstat -tap | grep mysql
  3. sudo vi /etc/mysql/my.cnf
  4. sudo service mysql restart

To look for some simple performance and security suggestions:

  1. sudo apt-get install mysqltuner
  2. mysqltuner

Adding a new user is equally easy…

  1. mysql --user=root --password=mypassword mysql
  2. CREATE USER 'myusername'@'%' IDENTIFIED BY 'mypassword';
    GRANT ALL PRIVILEGES ON *.* TO 'mydatabase'@'%' WITH GRANT OPTION;
    FLUSH PRIVILEGES;

NOTE: This allows access to the user from ALL hosts, it can be limited by replacing the '%' with a specific hostname (such as ‘localhost’ if desired) for security.
