How To Migrate Mailboxes Between IMAP Servers With IMAP TOOLS

Post date: October 27, 2011, 08:10 Category: Miscellaneous Views: 19192 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.

Post date: September 12, 2007, 22:09 Category: Optimizing Views: 3765 Comments
Tutorial quote: This tutorial shows how to install and use SpeedyCGI (also known as PersistentPerl) on a Debian Etch system.

Post date: November 5, 2006, 21:11 Category: System Views: 4236 Comments
Tutorial quote: This guide describes how to install and use xen-tools, xen-shell, and Argo on a Debian system. All three packages provide useful tools for the administration of virtual Xen machines. Xen-tools is a collection of Perl scripts that allow you to easily create, update, and delete Xen guest domains. The xen-shell provides a command-line interface to owners of Xen domains so that they can manage their Xen domains without the help of the server administrator. And with Argo, you can control Xen domains through a web interface or through a menu on the command line.

CGI Programming on the World Wide Web

Post date: December 12, 2005, 17:12 Category: Programming Views: 2980 Comments
Tutorial quote: The Common Gateway Interface (CGI) emerged as the first way to present dynamically generated information on the World Wide Web. CGI allows the computer to generate Web pages instantly at the user's request rather than being written by someone in advance. And at the time of this writing, it remains the only stable and well-understood method for creating such pages. Java presents problems that have not yet been solved. Other products are currently just in the announcement stage.

CGI is fun. You can get a kick out of writing scripts that perform tricks for you, and the users enjoy the spice the scripts add to your Web pages. But CGI has a serious side too: It lets the Internet offer the kind of interactive, user-driven applications that modern computer users have come to expect. CGI opens up an entire class of modern applications to the Web.

PHP-FPM/Nginx Security In Shared Hosting Environments (Debian/Ubuntu)

Post date: September 25, 2011, 16:09 Category: Security Views: 4993 Comments
Tutorial quote: If you want to use nginx and PHP-FPM for shared hosting environments, you should make up your mind about security. In Apache/PHP environments, you can use suExec and/or suPHP to make PHP execute under individual user accounts instead of a system user like www-data. There's no such thing for PHP-FPM, but fortunately PHP-FPM allows us to set up a "pool" for each web site that makes PHP scripts execute as the user/group defined in that pool. This gives you all the benefits of suPHP, and in addition to that you don't have any FTP or SCP transfer problems because PHP scripts don't need to be owned by a specific user/group to be executed as the user/group defined in the pool.
