This tutorial explains how you can mount a directory from a remote server on the local server securely using SSHFS. SSHFS (Secure SHell FileSystem) is a filesystem that serves files/directories securely over SSH, and local users can use them just as if the were local files/directories. On the local computer, the remote share is mounted via FUSE (Filesystem in Userspace). I will use Ubuntu 11.10 for both the local and the remote server. http://www.howtoforge.com/mounting-remote-directories-with-sshfs-on-ubuntu-11.10
This tutorial shows how to set up file synchronization between two Ubuntu 11.10 servers with Unison. Unison is a file-synchronization tool similar to rsync, but the big difference is that it tracks/synchronizes changes in both directions, i.e., files changed on server1 will be replicated to server2 and vice versa.
This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I'll also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota. Passwords are stored in encrypted form in the database. In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV. I will also show how to install SquirrelMail as a webmail interface so that users can read and send emails and change their passwords. http://www.howtoforge.com/virtual-users-and-domains-with-postfix-courier-mysql-and-squirrelmail-ubuntu-11.10
This tutorial shows how to prepare an Ubuntu 11.10 (Oneiric Ocelot) server with nginx for the installation of ISPConfig 3, and how to install ISPConfig 3. Since version 3.0.4, ISPConfig comes with full support for the nginx web server in addition to Apache, and this tutorial covers the setup of a server that uses nginx instead of Apache. ISPConfig 3 is a webhosting control panel that allows you to configure the following services through a web browser:
nginx and Apache web server, Postfix mail server, MySQL, BIND or MyDNS nameserver, PureFTPd, SpamAssassin, ClamAV, and many more.
