Installing Dnsmasq for wildcard local domains on Debian

Install

sudo apt-get install dnsmasq

Configure

sudo vim /etc/dnsmasq.conf

Add this:

address=/example.com/127.0.0.1
listen-address=127.0.0.1

This maps *.example.com to 127.0.0.1 – replace with the domain you want to use. It also makes dnsmasq only respond to local requests for security – this is optional.

Restart to load the new configuration:

sudo /etc/init.d/dnsmasq restart

Test it:

nslookup abc.example.com 127.0.0.1

It should say something like:

Server: 127.0.0.1
Address: 127.0.0.1#53

Name: abc.example.com
Address: 127.0.0.1

Override the nameserver to use for lookups

sudo vim /etc/dhcp/dhclient.conf

Add:

prepend domain-name-servers 127.0.0.1;

Restart the network:

sudo ifdown eth0; sudo ifup eth0

Adjust as necessary if your interface is not named eth0. Run ifconfig to get the interface name if you’re not sure.

Check that it worked:

cat /etc/resolv.conf

It should say something like:

domain home
search home
nameserver 127.0.0.1
nameserver 192.168.32.254

Note that 127.0.0.1 is the first nameserver.

Test:

nslookup abc.example.com

It should say the same thing as it did above.

Upgrade from PHP 7.0 to PHP 7.1

Add Ondrejs PPA Repo

PPA’s or Personal Package Archive, is a collection of software not included in Ubuntu by default. Typically these repositories focus on a single program, but they can include more depending on the person maintaining them. Ondřej Surý has created this PPA which has the latest versions of PHP in it. Lets add it to your system, and update to get a list of all the software we can install.

$ sudo add-apt-repository ppa:ondrej/php
$ sudo apt-get update

Install PHP 7.1

Lets stop our server first, then install PHP 7.1.

$ service apache2 stop
$ sudo apt-get install php7.1 php7.1-common

We’ll also install some extra packages for our PHP installation – these are needed for Laravel and Composer!

$ sudo apt-get install php7.1-curl php7.1-xml php7.1-zip php7.1-gd php7.1-mysql php7.1-mbstring php7.1-mysql

Once that is done, lets check PHP is updated on the CLI

$ php -v

If the first row looks like this, we’ve done good so far! PHP 7.1.11-1+ubuntu16.04.1+deb.sury.org+1 (cli) (built: Oct 27 2017 13:49:56) ( NTS )

Remove PHP 7.0

Now we have PHP7.1, lets get rid of PHP7.0

$ sudo apt-get purge php7.0 php7.0-common

Once this has been done, I usually restart the server.

$ sudo shutdown -r now

Make PHP7.1 used by Apache

Finally, we need to tell Apache to use PHP7.1 now PHP 7.0 is not being used. Lets enable the PHP mod!

$ a2enmod php7.1
$ service apache2 restart

Thats it – PHP should now be using PHP 7.1 – enjoy your amazing new features such as function return types and multiple error catch’s! If you are having issues, feel free to prod me on Twitter at @bhaktaraz

Detect OnePlus5 in Ubuntu in MTP mode

So if you have connected OnePlus 5 to Ubuntu, you will notice that you can only see “OnePlus Drivers” as mounted but you cannot access the internal memory using MTP, although ptp works!

So here is what you need to do to make it possible

1. Enable Developer options in Settings
2. Enable ADB ( this needs to be enabled else, mtp doesnt work )
3. Open a terminal window and follow this :
– we will edit 2 files and add some lines in them. My preferred editor is vim. you may use nano / emacs etc.

COMMAND :

sudo vim /lib/udev/rules.d/69-mtp.rules

ADD LINE :

ATTR{idVendor}==”2a70″, ATTR{idProduct}==”9011″, SYMLINK+=”libmtp-%k”, ENV{ID_MTP_DEVICE}=”1″, ENV{ID_MEDIA_PLAYER}=”1″

save and exit

COMMAND :

sudo vim /etc/udev/rules.d/51-android.rules

ADD LINE : 

ATTR{idVendor}==”2a70″, ATTR{idProduct}==”9011″, MODE=”0666″

save and exit

COMMAND :

sudo service udev restart

Now disconnect and reconnect your phone, you will have “Android Device” as the mtp device.

If you still cannot see, reboot and try to see if the device is now visible!

Thankyou!
