Tuesday, May 17, 2016 @ 10:22:51 UTC by lbadmin (4006 reads)
Ubuntu Linuxgg234 writes
In around 15 minutes, the time it takes to install Ubuntu Server Edition, you can have a LAMP (Linux, Apache, MySQL and PHP) server up and ready to go. This feature, exclusive to Ubuntu Server Edition, is available at the time of installation.The LAMP option means you don?t have to install and integrate each of the four separate LAMP components, a process which can take hours and requires someone who is skilled in the installation and configuration of the individual applications. Instead, you get increased security, reduced time-to-install, and reduced risk of misconfiguration, all of which results in a lower cost of ownership.Currently this installation provide PostgreSQL database, Mail Server, Open SSH Server,Samba File Server, Print Server, Tomcat Java Server,Virtual Machine Host,Manual Package selection,LAMP and DNS options for pre-configured installations, easing the deployment of common server configurations.

How to configure NFS Server and Client Configuration on Ubuntu 15.04
Wednesday, January 27, 2016 @ 10:23:33 UTC by lbadmin (7812 reads)
Ubuntu Linuxgg234 writes
NFS was developed at a time when we weren't able to share our drives like we are able to today -- in the Windows environment. It offers the ability to share the hard disk space of a big server with many smaller clients. Again, this is a client/server environment. While this seems like a standard service to offer, it was not always like this. In the past, clients and servers were unable to share their disk space.Thin clients have no hard drives and thus need a "virtual" hard-disk. The NFS mount their hard disk from the server and, while the user thinks they are saving their documents to their local (thin client) disk, they are in fact saving them to the server. In a thin client environment, the root, user and home partitions are all offered to the client from the server via NFS. Full Story

This tutorial will teach you how to set up your own robust email server. We are focusing on a small personal server with up to a few email accounts.

  • SPF (Sender Policy Framework) validating to reduce spam
  • SPF DNS entry to prevent spoofing
  • DKIM (Domain Keys Identified Mail) to sign our email messages
