enable ssh ubuntu 14.10

Secure Shell (SSH) is a protocol for securely accessing remote machine, it allows you to run command line and graphical programs, transfer files, and even create secure virtual private networks over the Internet.

Ubuntu does not provide the ssh service out-of-the-box. But you can easily enable it by installing the OpenSSH server package.

To enable SSH:

Search for and install the openssh-server package from Ubuntu Software Center. Or run command below in console if you’re on Ubuntu Server without GUI:

sudo apt-get install openssh-server

Once installed, the SSH service should be started automatically. If necessary, you can start (or stop, restart) the service manually via command:

sudo service ssh start

To edit settings:

To change the port, root login permission, you may edit the /etc/ssh/sshd_config file via:

sudo nano /etc/ssh/sshd_config

After you changed the configurations, press Ctrl+X followed by typing y and hitting enter to save the file.

Finally restart the SSH service to apply the changes:

sudo service ssh restart

Usage and Tips:

1. Normally, we can access remote machine through SSH via command:

ssh username@remote-ip

For the port that is not the default 22:

ssh username@remote-ip -p NUMBER

2. For desktop Ubuntu, root user need to be enabled first so that remote machines can SSH to it via root:

Run command below to set a password for root:

sudo passwd root

Then execute command to unlock the root account:

sudo passwd -u root

Edit the config file /etc/ssh/sshd_config, change the line

PermitRootLogin without-password

into:

PermitRootLogin yes

When done, restart the SSH service.

Install utorrent ubuntu 14.10

µTorrent (or uTorrent) is a free, closed source, and most widely used BitTorrent client available in Windows, Mac OS, and Linux. The program was designed to use minimal computer resources while offering functionality comparable to larger BitTorrent clients such as Vuze or BitComet.

µTorrent for Linux is composed of a µTorrent server and a web based client. Below I will show you how to install it in Ubuntu step by step, tested in a fresh 64-bit Ubuntu 14.10 installation.

1. Download the official package from the link below:

Download uTorrent Server

You may first check out your OS type from shutdown menu (top-right gear button) -> About This Computer. Then select download “µTorrent Server for Ubuntu 13.04 – 32-bit or 64-bit”.

2. Once the downloading process finish, go to the Downloads folder in file browser and extract the package through its context menu.

extract-utserver

Tip: If you want other users on the Ubuntu system to be able to use the uTorrent server, extract the package to /opt/ directory. To do so, open Archive Manager as root/admin by running sudo file-roller in terminal, then open and extract the package.

3. Navigate to the result folder and run utserver from its context menu:

run-utorrent-server

That’s right you see nothing happens because the server is running as a background program.

Tip: If you don’t see the Run option in its right-click menu, do:

Go to Properties in its right-click menu, check the box where it says “Allow executing file as program” under Permissions tab.

4. Finally in your web browser go to http://localhost:8080/gui/. When it asks, type in:

username: admin
password: leave it empty.

That’s it. Enjoy!

install multimedia codecs, enable dvd playback

Due to legal constraints in many countries, Ubuntu does not include multimedia codecs to play mp3, movies, and DVDs out-of-the-box.

This quick tutorial will show you how to manually install the multimedia codecs to enable playback audio, video, DVDs in Ubuntu 14.10 Utopic.

Install Multimedia Codecs:

There is a package “Ubuntu restricted extras” available in Ubuntu Software Center. Installing it will pull in support for MP3 playback and decoding, support for various other audio & video formats such as mp4, avi, rmvb, wmv and more, Microsoft fonts, Flash plugin, LAME (to create compressed audio files), and DVD playback.

To install the package, just click the link below to bring up Ubuntu Software Center and click the install button:

install ubuntu-restricted-extras

During the installing process, you will be asked to accept the EULA license terms.

Tip: If you get a warning dialog says “to install ubuntu restricted extras, these items must be removed”, just click the ignore because -extra versions of these libraries will be installed instead, to provide additional functionality.

Enable DVD Playback:

After installed the package above, you should be able to play normal DVDs. But for playing encrypted DVDs, libdvdread4 and libdvdcss2 are also required.

Press Ctrl+Alt+T on keyboard to open the terminal. When it opens, paste the commands below to install libdvdread4:

sudo apt-get install libdvdread4

The package provides a simple script to download & install libdvdcss2, to run the script:

sudo /usr/share/doc/libdvdread4/install-css.sh

If you can’t get the libdvdcss2 package from the script, download & install,

  • libdvdcss2_1.2.13-0_amd64.deb for 64-bit Ubuntu.

  • libdvdcss2_1.2.13-0_i386.deb for 32-bit ubuntu.

from the page: download.videolan.org/ubuntu/utopic

When done, you should be able to playback (and navigate DVD menus) in most video applications, including the default Totem and VLC media player..
