 This page is for the things I learn on my Linux travels. Mainly this (at the time of writing) due to several Linux based products in my workplace (CentOS based) and the truly amazing Raspberry Pi range. I have not yet decided whether to split the Linux page in to two sub categories to reflect this.
+\\
+\\
+The commands here will work regardless of the Raspberry Pi hardware (not sure about the compute module) but will work with the Raspberry Pi1/2/3 and Zero.

 [[Configure Static IP Address]]\\
 [[Command Line MySQL]]\\
-===== UFW - Uncomplicated Firewall =====
+[[UFW - Uncomplicated Firewall]]\\
-\\
+[[Restart Apache2 Web Server]]\\
-\\
+[[Check Disk Space]]\\
-Uncomplicated Firewall //**UFW**// is a much simpler security solution than using iptables, it is very easy to install and configure. iptables might ultimately have more features, but I think UFW is suitable for most users.
+[[Change Password]]\\
-\\
-\\
-To install //**UFW**// from the command line:
-\\
-//**sudo apt-get install ufw**//
-\\
-\\
-To allow all ports on the local subnet:
-\\
-//**sudo ufw allow from 192.168.0.0/24**// (allow access from 192.168.0.1 - 192.168.0.254)
-\\
-\\
-Allow web port 80 to everyone (internal and external LAN)
-\\
-//**sudo ufw allow 80**//
-\\
-\\
-To enable UFW and start rules:
-\\
-//**sudo ufw --force enable**//
-\\
-\\
-\\
-===== Restart Apache2 Web Server =====
-\\
-\\
-From time to time it might be necessary to restart the Apache Web Server, normally this is required after a configuration change, or if a site has stopped.
-\\
-\\
-From the command line:
-\\
-//**sudo /etc/init.d/apache2 restart**//
-\\
-\\
-\\
-===== Check Disk Space =====
-\\
-\\
-Working from the command line has some disadvantages, one of those is that you don't have a constant graphical reminder of physical and available disk space. To check this we can use the command //**df**// which stands for //**disk filesystem**//
-\\
-\\
-From the command line:
-\\
-//**df -h**// --- (the -h means human readable format, so instead values being in bytes, they are displayed at MB or GB etc)
-\\
-\\
-$ df -h\\
-\\
-Filesystem      Size  Used Avail Use% Mounted on\\
-/dev/root       6.0G  3.7G  2.0G  66% /\\
-devtmpfs        214M     0  214M   0% /dev\\
-tmpfs           218M     0  218M   0% /dev/shm\\
-tmpfs           218M  4.5M  213M   3% /run\\
-tmpfs           5.0M  4.0K  5.0M   1% /run/lock\\
-tmpfs           218M     0  218M   0% /sys/fs/cgroup\\
-/dev/mmcblk0p6   63M   20M   43M  32% /boot\\
-tmpfs            44M     0   44M   0% /run/user/1000\\

-===== Change Password =====
-\\
-\\
-To change the password for a user, when logged in as that user, from the command line enter:
-\\
-\\
-//** sudo passwd pi **// --- (make sure you use the correct username, pi is just for the example)
-\\
-you will then be prompted to enter, then re-enter the new password
-\\
-\\
-//**
-$ sudo passwd pi\\
-Enter new UNIX password:\\
-Retype new UNIX password:\\
-passwd: password updated successfully
-**//
