#Linux - Basic Security

##Restricting Remote IP Addresses

It is always a good idea to restrict the access to users and hosts that you trust. To do this you need to:

Edit the /etc/hosts.deny and create a rule

sshd: ALL

#Node - Running in Production This gist is based on the excellent post by @hacksparrow which is found at http://www.hacksparrow.com/running-express-js-in-production-mode.html. The main principle is that you want the application to detect that it is running on a production server and to use the production configuration. The way to do this is to set the NODE_ENV=production. To do this you need to do the following:

$ export NODE_ENV=production

But we have a little problem here. The NODE_ENV environment variable will be lost if the server restarts, so it is safer to put it in the .bash_profile file. That way the variable will set again every time the system reboots. You will find the file in your home directory. It's a hidden file, so you can't see it unless you do a ls -la. We will append the export command to the .bash_profile file.

#Linux - Production Server Setup The principle of running a server in production is to run only what is needed. This keeps the server load to a minimum and reduces the security footprint.

##Setup the Domain Name (DNS) Point the dns address at the ip address of your server. If the server is rented you should already have a static ip address. If the machine is on your local network you may have to sudo nano /etc/network/interfaces to edit the ip address file. Your setup should be like:

iface eth0 inet static

#Linux - Cron Basics

Cron is a linux scheduling service which is used primarly on servers. It works by waking up each minute and checking its configuration files (known as crontabs) to see if there is anything to run. Cron is normally started at boot time.

###Typical uses:

• Rotating log files
• Summarising log files (ie Logwatch and Webalizer)
• Autochecking for Distro updates
• Performing Backups

#DNS Basics Domain names are a core feature of the internet. It is simply a mechanism to give a friendly name to remove the need to use ip addresses directly. It also has a number of advantages, such as:

1. It allows you to have more than one domain name pointing at the same ip address (ie same website).
2. It allows you to host more than one website on a specific ip address (ie shared hosting, the website shown in the one associated with the domain name)

#Linux - Running a Node Service (PM2) PM2 is a replacement for Forever which is used to run Node services (see http://devo.ps/blog/2013/06/26/goodbye-node-forever-hello-pm2.html). It has a number of advantages over forever:

• Log aggregation
• API
• Terminal monitoring
• Clustering
• JSON configuration
