Upgrade OpenSSL on Ubuntu 14.04.2 LTS x64

Posted on Updated on

In this post I am going to tell you the steps to upgrade OpenSSL in Ubuntu 14.04 LTS x64.

Caution: Please make sure you have a complete backup of your current Ubuntu system before performing these steps.

Steps:

  1. By default Ubuntu 14.04 LTS comes with OpenSSL version 1.0.1j 15 Oct 2014. You can check this by typing the command “openssl version“.
  2. Install the build essential and check install packages by typing “sudo apt-get install checkinstall build-essential“.
  3. Download the OpenSSL version from the link. I downloaded the version 1.0.1u and extracted the files from tar.
  4. Run command “sudo ./config“.
  5. Then “sudo make“.
  6. Followed by “sudo make install“. This will install the OpenSSL in the “/usr/local/ssl“.
  7. Now go to “/usr/bin” directory and change the openssl name by typing “sudo mv openssl openssl_ORIG
  8. Next type command “sudo ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl/” which will create a symbolic link of the latest openssl binary.
  9. Reboot you’re Ubuntu.
  10. Now when you type the “openssl version” command you should get the latest version of OpenSSL; in this case it should be 1.0.1u.

How to block a WEBSITE / URL Link on PTCL WiFi ADSL Router ?

Posted on Updated on

Hello, today’s article is about configuring your PTCL ADSL WiFi Router for blocking a “website / URL Link”. The PTCL ADSL WiFi Router I am using comes with a lot of features and security settings. This article is about configuring/using the “Url Filter” feature.

Advantage
The advantage of blocking on PTCL ADSL WiFi Router is that the website / URL Link will not be accessible to any device (PC, Laptop, Mobile phone, Tablet etc.) present in the network. So, you don’t have to block it one each device or use some software firewall, just add it to the router and its blocked for all the users inside the network.

Note: Please note you can’t block HTTPS webistes/URL Links on your PTCL ADSL WiFi Router. Only HTTP websites will be blocked. If the “green secure” bar/words doesn’t show up in the browser it means the  website is on HTTP. Most of the websites are now running on HTTPS.

Idiots Guide: How to connect two PTCL ADSL (wifi) routers in a network via LAN ?

Posted on Updated on

Hello, hope you are having a good day or may be not!!! You are confused and frustrated about configuring two routers in your home network (LAN). If you are facing this problem. Just sit back and relax because this tutorial will guide you on how to fix this problem.

Scenario:

Somehow I have got two PTCL routers from the PTCL. Both the routers are ADSL + WIFI routers as shown in the following figures.

New router: SLIM

SLIM Router
SLIM Router

Old router: FAT

FAT Router

Now the SLIM router is my primary router i.e. the PHONE LINE after DSL SPLITTER comes to this router and all the devices in my home connects to this one via WIFI or a CAT5/6 cable. Now, I have another spare router (FAT) and I want to use this router in another room because I am not getting good signals with my SLIM router. Also, I want this FAT router to be a part of my existing network.

Existing network:

Problem:

To Install / Configure a PTCL’s ADSL + WIFI router (FAT) in the existing network because we want to install the NEW router in another room to get GOOD WIFI SIGNALS.

Modified network:

Steps: 

1. First you need to find out the network address of your ROUTER that is connected to the INTERNET in my case its the SLIM router. SLIM router is on the “192.168.1.1”, most of the PTCL routers are assigned this private IP address. You can also verify it by typing “192.168.1.1” address in your browser, it will ask you USERNAME + PASSWORD to login. Afterwards you will be shown to a screen similar to following:

SLIM router LOGIN PAGE
SLIM router LOGIN PAGE

2. Now, the second step is to find the network address of our FAT router. Just like the SLIM router it will also be running on the IP address “192.168.1.1”. To connect with this router. I would recommed the following steps:

  • TURN OFF your SLIM router
  • POWER UP this FAT router
  • Connect you PC/Laptop with this FAT router via WIFI or NETWORKING CABLE (CAT 5/6) [ i used the networking cable method]
  • LOG into the ADMIN PAGE of this FAT router by typing “192.168.1.1” into your browser
  • A similar screen like previous router’s admin page will be shown as shown in the following picture
FAT router login page
FAT router LOGIN page

3. Third step involves configuring this FAT router. So, that we can adjust it in our existing network.

  • In the Advanced Setup tab click on the LAN button
  • Now change the IP address so that we don’t have any conflict with our SLIM router
  • I will be assigning ip address of 192.168.1.100 to this FAT router
  • And after this you need to DISABLE the DHCP server
  • After this go to the Routing tab and click on Default Gateway button
  • Check the Use Default Gateway IP address and assign the IP address of your primary router, in my case it will be 192.168.1.1
  • Save settings and reboot your router
  • Following figures shows these steps

4. After the restart, this FAT router will be availble to access on the “192.168.1.100” IP address.

FAT router @ 192.168.1.100
FAT router @ 192.168.1.100

5. Now,  the next step involves configuring the WIFI of this WIFI router. Give this FAT router a diffrent SSID  (name). In my case I am giving it the name of “Free Internet”, you can do whatever you want. If you want to protect your WIFI, you can go to the SECURITY settings and put a password too.

6. Next, you need to physically connect both the WIFI routers via a LAN CABLE (cat6).
Place this FAT router in your desired location / floor.

7. Next, step is to connect with the FAT router via “WIFI”. If you look at the WIFI connections in your operating system in my case its windows. “Free Internet” will be shown.

SSID: Free Internet
SSID: Free Internet

8. Connect with this “Free Internet”.

9. You will be connected to “Free Internet” but you will not be able to browse/surf any website. Its because of the fact that you have TURNED OFF THE DHCP and your system has not been assigned any IP. To fixed this issue, you will have to manually assign IP Address, Default Gateway, Netmask etc. settings as shown below

Settings on Client Side

10. Save settings and “Disable” and then “Enable” your wireless adapter so that settings gets in.

11. After this, you will be successfully able to use INTERNET from this FAT router. Hurrah !!!

12. Please remember that you will have to do manual configuration of devices (laptop, mobile etc.) that will be connected to FAT router. Else, it won’t work.

Feel free to ask questions if you have any !!!

Note:
If you have different routers just remember that you just need to turn off the “DHCP” on the second router and give the second router default gateway IP of the primary router. Thats it.
