Installing KVM Guests With virt-install On Ubuntu 11.10 Server

Post date: November 27, 2011, 11:11 Category: Miscellaneous Views: 27124 Comments
Tutorial quote: Unlike virt-manager, virt-install is a command line tools that allows you to create KVM guests on a headless server. You may ask yourself: "But I can use vmbuilder to do this, why do I need virt-install?" The difference between virt-install and vmbuilder is that vmbuilder is for creating Ubuntu-based guests, whereas virt-install lets you install all kinds of operating systems (e.g. Linux, Windows, Solaris, FreeBSD, OpenBSD) and distributions in a guest, just like virt-manager. This article shows how you can use it on an Ubuntu 11.10 KVM server.

How To Migrate Mailboxes Between IMAP Servers With IMAP TOOLS

Post date: October 27, 2011, 08:10 Category: Miscellaneous Views: 19191 Comments
Tutorial quote: This guide explains how you can migrate mailboxes between IMAP servers with IMAP TOOLS. IMAP TOOLS is a collection of Perl scripts that allow you to do various tasks with IMAP servers and also POP3 servers. In this article I will focus on the scripts imapcopy.pl (copies messages and mailboxes from one IMAP server to another) and pop3toimap.pl (copies POP3 messages to an IMAP server). Both scripts support SSL. If you specify port 993 (995 for POP3) then an SSL connection is initiated. If the port number is 143 (110 for POP3) then it will try a non-SSL connection. With any other value the port will be tested to see if it supports SSL. If so, SSL will be used to make the connection; otherwise a non-SSL connection will be made.

I will outline two solutions: the first is to proxy requests for CGI scripts to Thttpd, a small web server that has CGI support, while the second solution uses a CGI wrapper to serve CGI scripts.

Mounting Remote Directories With SSHFS On Debian Squeeze

Post date: September 22, 2011, 10:09 Category: Miscellaneous Views: 4099 Comments
Tutorial quote: 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 Debian Squeeze for both the local and the remote server.

How To Set Up SSL Vhosts Under Nginx + SNI Support (Ubuntu 11.04/Debian Squeeze)

Post date: September 13, 2011, 09:09 Category: Miscellaneous Views: 4651 Comments
Tutorial quote: This article explains how you can set up SSL vhosts under nginx on Ubuntu 11.04 and Debian Squeeze so that you can access the vhost over HTTPS (port 443). SSL is short for Secure Sockets Layer and is a cryptographic protocol that provides security for communications over networks by encrypting segments of network connections at the transport layer end-to-end. In addition to that I will show how to make use of SNI (Server Name Indication) to allow multiple SSL vhosts per IP address.
