# maximum capability of system
user@ubuntu:~$ cat /proc/sys/fs/file-max
708444

# available limit
user@ubuntu:~$ ulimit -n
1024

# To increase the available limit to say 200000
user@ubuntu:~$ sudo vim /etc/sysctl.conf

These commands are based on a askubuntu answer http://askubuntu.com/a/581497
To install gcc-6 (gcc-6.1.1), I had to do more stuff as shown below.
USE THOSE COMMANDS AT YOUR OWN RISK. I SHALL NOT BE RESPONSIBLE FOR ANYTHING.
ABSOLUTELY NO WARRANTY.

If you are still reading let's carry on with the code.

sudo apt-get update && \
sudo apt-get install build-essential software-properties-common -y && \
sudo add-apt-repository ppa:ubuntu-toolchain-r/test -y && \

rdcm

Run the following in the terminal:

Install the gcc-7 packages:

sudo apt-get install -y software-properties-common
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt update
sudo apt install g++-7 -y

Set it up so the symbolic links gcc, g++ point to the newer version:

source: http://www.markbrilman.nl/2011/08/howto-convert-a-pfx-to-a-seperate-key-crt-file/

`openssl pkcs12 -in [yourfile.pfx] -nocerts -out [keyfile-encrypted.key]`

What this command does is extract the private key from the .pfx file. Once entered you need to type in the importpassword of the .pfx file.  This is the password that you used to protect your keypair when you created your .pfx file.  If you cannot remember it anymore you can just throw your .pfx file away, cause you won’t be able to import it again, anywhere!.  Once you entered the import password OpenSSL requests you to type in another password, twice!. This new password will protect your .key file.

Now let’s extract the certificate:

`openssl pkcs12 -in [yourfile.pfx] -clcerts -nokeys -out [certificate.crt]`
