Virtual Users And Domains With Postfix, Courier And MySQL (+ SMTP-AUTH, Quota, SpamAssassin, ClamAV)

Post date: October 9, 2005, 18:10 Category: Network Views: 4571 Comments
Tutorial quote: This document describes how to install a mail server based on Postfix 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 (quota is not built into Postfix by default, I'll show how to patch your Postfix appropriately). Passwords are stored in encrypted form in the database (most documents I found were dealing with plain text passwords which is a security risk). In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses.

Distributed Replicated Storage Across 4 Nodes With GlusterFS On Mandriva 2010.0

Post date: April 20, 2010, 12:04 Category: Installing Views: 5088 Comments
Tutorial quote: This tutorial shows how to combine four single storage servers (running Mandriva 2010.0) to a distributed replicated storage with GlusterFS. Nodes 1 and 2 (replication1) as well as 3 and 4 (replication2) will mirror each other, and replication1 and replication2 will be combined to one larger storage server (distribution). Basically, this is RAID10 over network. If you lose one server from replication1 and one from replication2, the distributed volume continues to work. The client system (Mandriva 2010.0 as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.

Split and Reassemble Files

Post date: September 20, 2006, 20:09 Category: Software Views: 4973 Comments
Tutorial quote: There always comes a time, where you wish that file was only a few kilobytes/megabytes smaller. Wether it be so it can fit onto your floppy disk, CDR etc, or so you can meet the attachment limit on an e-mail server. This isn't really a command that you would use everyday, but it might come in handy.
