How to stream movies on Samsung smart TV using Popcorn Time in Linux

If you're movies and torrent lovers, you might have heard of Popcorn Time. For those new to this technology Popcorn Time is  a multi-platform, free software BitTorrent client that includes an integrated media player. The applications provide a free alternative to subscription-based video streaming services (such as Netflix). Popcorn Time uses sequential downloading to stream video listed by several torrent websites (although other trackers can be added and used manually).
The software has been closed several times due to copyright issues, but now is available again, am going to explain step by step on how to stream movies on smart TV from Popcorn Time software running on Linux Machine (Deepin Linux which is based on Ubuntu 14) in the following easy steps.

a. Download the Popcorn software from its current offical site.

The current site is  https://popcorntime.sh/

Save the file in any of your preferred place, for mine it goes to Downloads.

b. Extract the downloaded file.

The extracted file will be called Linux but you may name it to any name of your preference.

c. Open the extracted folder and run the file called Popcorn-Time.

Inside the extracted folder you're going to find 3 folders and 8 files as seen below.

Below is the next screen after running Popcorn-Time file.

d. Choose movie,series, anime etc of your choice and start streaming.

Below is what i choose for demonstration.

e. Connect Popcorn-Time to To Samsung smart TV.

If your smart TV is connected in the same network where your computer is connected, you will see it when you click Watch now icon on selected movie as seen below,

As you can see above the watch now icon shows which media you can stream the movie from, which are TV (my Samsung LED smart TV), VLC (because is installed on my machine) and butter (default Popcorn Time media) players.Choose Samsung TV for streaming and press Watch now.

f. Allow Popcorn-Time to stream on your TV and Enjoy.

If it the first time to connect Popcorn to your TV you may have to allow it to access your TV.

After connecting and while the downloading is on progress also the streaming will be on progress.

How to connect devices running on GNS3 to Internet in Ubuntu/Deepin

Hello everyone, you may came in a situation where you will need to connect devices running on visualization environment like GNS3 to Internet, here are steps.

i. Launch gns3 on command line

➜  ~  sudo gns3

ii. Add devices
For this lab, am going to use one router Cisco router 7200 and Cloud which will be connecting gns3 devices to Internet via my laptop which is connected to Internet using Ethernet cable connected to router .

iii. Cabling and bridging Cloud to the to my Ethernet interface.

Right-click on Cloud and select configure, then add etho (which is interface of my laptop as generic interface of the cloud) and then Appy and save.

Now connect interface of the router to this generic interface of the cloud.

Now power on the router for further configuration.

iv. Router Configuration
Now login to the router for configuration

➜  ~  telnet 127.0.0.1 2001
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
Connected to Dynamips VM "R1" (ID 1, type c7200) - Console port
Press ENTER to get the prompt.
ROMMON emulation microcode.

 a. Configure interface
Configure the interface to obtain IP address via dhcp of my public router (you may assign static IP also if you prefer).

R1#show ip interface brief Interface              IP-Address      OK? Method Status                Protocol
FastEthernet0/0        unassigned      YES unset  administratively down down  
R1#
R1#config tEnter configuration commands, one per line.  End with CNTL/Z.
R1(config)#interface fastEthernet 0/0R1(config-if)#ip address dhcp
R1(config-if)#no shutdown
R1(config-if)#
R1(config-if)#

*Oct  8 13:06:28.963: %LINK-3-UPDOWN: Interface FastEthernet0/0, changed state to up
*Oct  8 13:06:29.963: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up
R1(config-if)#
*Oct  8 13:06:37.907: %DHCP-6-ADDRESS_ASSIGN: Interface FastEthernet0/0 assigned DHCP address 192.168.0.17, mask 255.255.255.0, hostname R1

R1(config-if)#

As you can see the interface is assigned 192.168.0.17 IP from the router dhcp

b. Configure default gateway

R1(config-if)#exit
R1(config)#ip route 0.0.0.0 0.0.0.0 192.168.0.1

Now you are able to access the internet from the router

R1#ping 8.8.8.8 

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 8.8.8.8, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 160/169/196 ms
R1#

c. Further config to enable users to login to the router remotely, configure passwords and also dns configuration.

Dns configuration

R1(config)#ip domain lookup
R1(config)#ip name-server 8.8.8.8 8.8.4.4

Configure password to allow remote login

R1(config)#line console 0
R1(config-line)#transport preferred none
R1(config)#line vty 0 4
R1(config-line)#transport preferred none 

R1(config)#username admin secret admin@2015
R1(config)#enable secret admin@2015
R1(config)#service password-encryption 

R1(config)#aaa new-model
R1(config)#aaa authentication login default local
R1(config)#aaa authentication enable default enable

      R1(config)#exit

      R1#wr

Ping google.com to test DNS

R1#ping google.com
Translating "google.com"...domain server (192.168.0.1) [OK]
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 41.220.141.187, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 8/16/28 ms
R1#

Now your good, the router is online, and anyone within your network can login.

Enjoy!!!!!.

Solved!!! The problem of wifi disconnection in Dell Latitude 7450 (7000 Series) when using Ubuntu/Deepin Linux

Friend of mine bought dell latitude 7450 which came with window 8 Pro, but because the guy is in love with Linux he installed Deepin Linux (http://www.deepin.org/) a linux distro based on Ubuntu, soon after installation he started facing problem of wifi disconnection which was so bad as sometimes the wifi forgets the password so he was supposed to retype the password every time it disconnects.
We take as challenge, and starting working with on it, where we discovered that the computer come with Intel Wireless 7265 card which has problem of loading the wifi driver in Ubuntu and all Ubuntu derivative distros.
The solution is to reinstall the drivers manually, by following the below two simple steps.

1. Download the kernel driver from this link (https://www.kernel.org/pub/linux/kernel/projects/backports/stable/v3.18.1/backports-3.18.1-1.tar.xz), although the driver is based on kernel version 3.18 but it works well also for kernel 3.13 ,and save it to desktop, then run the following commands,

sudo apt-get install linux-headers-generic build-essential
cd ~/Desktop/backports-3.18.1-1
make defconfig-iwlwifi
make
sudo make install

2. Download the firmware from the following link (https://wireless.wiki.kernel.org/en/users/Drivers/iwlwifi#Firmware), from documentation they suggested to use -9 for kernel version 3.17 but because we have kernel version 3.13 we downloaded both -8,9 and 10, download them on Download folder and extract then run the following commands,

cd ~/Downloads/iwlwifi-7265-ucode-23.11.10.0
sudo mv iwlwifi*  /lib/firmware

cd ~/Downloads/iwlwifi-7265-ucode-25.228.9.0
sudo mv iwlwifi*  /lib/firmware

cd    ~/Downloads/iwlwifi-7265-ucode-22.24.8.0
sudo mv iwlwifi* /lib/firmware

sudo chmod 644 /lib/firmware/iwl*

Reboot your computer for the change to take effect.


Problem solved, Enjoy!
