Updated for Ubuntu 14.04-3 LTS. If you are a home user and your network has grown such that you are tired of using all static IP addresses and having to configure the /etc/hosts files by hand, then use the great tool dnsmasq. See my How to set up dnsmasq. Dnsmasq is so much simpler to setup and maintain than bind9.
Installing NFS on Ubuntu
The Network File System (NFS) was developed to allow machines to mount a disk partition on a remote machine as if it were a local disk. It allows for fast, seamless sharing of files across a network.
Make the SWAP Space Span 3 disks With Stripping.
Once the system is installed do not forget to configure the priority of the swap spaces. If the priority is set correctly then all your swap spaces will be used as it they are stripped making it faster.
To see the current swap space setup use the command :
swapon -s
Ubuntu minimal Install with MATE as the Desktop 14.04 LTS
I find the simplest way to install Ubuntu with MATE as the desktop with the minimum I can get away with is to start with the server ISO. Yes, I know there are smaller initial downloads when using the netboot image but that means you need to set up the whole net booting server system. That seems to be over kill and involves a lot more downloading and work. Especially when you are only going to use it once.
The resulting Ubuntu server installation takes about 1.5G of disk space. With MATE it goes to 2.5GB up to 4GB for the full Ubuntu install.
Adding htaccess Password to Web Pages
Make sure that the Apache option AccessFileName has a value set, eith in the glabal configuration file, or in the config file for your virtual host.
/etc/apache2/apache.conf
/ect/apache2/sites-available/virtual-host
Simple anti-spam Measure for Email
I use a very simple system with my incoming email addresses that reduce spam to almost zero.
If you have your own domain or if your ISP allows you to setup aliases/forwrding to your real email address it is simple.
Whenever you deal with a new company, set-up a new email address. Whenever you have to open an account with a company say its called spammers inc. 🙂 After all most, if not all companies only want your details to spam you with marketing or pass your details on for a profit. Anyway, create a forwarding address to your real email address called from_spammers_inc@yourdomain.co.uk If you later start to get junk mail from anyone other than spammers inc on that address you know they have passed your email address on.
Installing and Configuring ssh
I install openssh server and sort out the configuration of ssh so I can login to other machines locally without a password. This is a security risk! I also want to use Xwindows programs installed and run on one machine while actually running on another, hence the ForwardX11 bit. Also considered a security risk by some.
Getting a Packard Bell Scanner Working on Linux
If you haven’t already done so do not buy a Packard Bell scanner get something else!
If that is too late then at least in Linux (unlike Vista) you can get it to work. The Diamond 1200 plus is as far as I can tell from the web a rebadged Mustek Bearpaw 1200 something.
