Filesystem Encryption Tools for Linux

Post date: May 28, 2007, 00:05 Category: System Views: 4312 Comments
Tutorial quote: Crypto filesystems keep your data safe – even if someone steals your computer.Linux offers a number of encrypted filesystem options – each with a different approach to the encryption problem.Encrypted filesystems may be overkill
for family photos or your résumé, but they make sense for network-accessible servers that hold sensitive business
documents, databases that contain credit-card information, offline backups, and laptops.

Streaming music with SlimServer

Post date: June 15, 2005, 16:06 Category: Network Views: 4242 Comments
Tutorial quote: Converting your CD collection into MP3 or another digital file format gives you the ability to enjoy the music on your computer and stream it all over the house and the Internet. To do the latter, however, you have to install and configure a streaming server on your computer. That might sound like a daunting task, but there is a streaming server application that makes the whole process pretty painless. SlimServer from Slim Devices is a cross-platform streaming server that runs on Windows, Linux, and Mac OS X and supports a wide range of formats, including AAC, AIFF, FLAC, Ogg Vorbis, MP3, WAV, and WMA. Although it was developed to stream music files to Slim Devices' Squeezebox2 hardware player, it works perfectly with any software MP3 player capable of working with network streams.

Squeeze Your Gigabit NIC for Top Performance

Post date: June 25, 2005, 01:06 Category: Optimizing Views: 5114 Comments
Tutorial quote: Many new workstations and servers are coming with integrated gigabit network cards, but quite a few people soon discover that they can't transfer data much faster than they did with 100 Mb/s network cards. Multiple factors can affect your ability to transfer at higher speeds, and most of them revolve around operating system settings. In this article we will discuss the necessary steps to make your new gigabit-enabled server obtain close to gigabit speeds in Linux, FreeBSD, and Windows.

File Server Configuration in Debian Using Samba

Post date: May 1, 2007, 05:05 Category: System Views: 4583 Comments
Tutorial quote: Samba is a suite of Unix applications that speak the SMB (Server Message Block) protocol. Many operating systems,including Windows and OS/2, use SMB to perform client-server networking. By supporting this protocol, Samba allows Unix servers to get in on the action, communicating with the same networking protocol as Microsoft Windows

products.

Installing and securing Squid

Post date: March 13, 2006, 15:03 Category: Software Views: 5727 Comments
Tutorial quote: Squid is a high-performance proxy caching server for web clients, supporting FTP, gopher, and HTTP data objects. Unlike traditional caching software, Squid handles all requests in a single, non-blocking, I/O-driven process. Squid keeps meta data and especially hot objects cached in RAM, caches DNS lookups, supports non-blocking DNS lookups, and implements negative caching of failed requests. Squid supports SSL, extensive access controls, and full request logging. By using the lightweight Internet Cache Protocol, Squid caches can be arranged in a hierarchy or mesh for additional bandwidth savings.

After the installation and base configuration of squid we will add another layer of security by chrooting it.

Xen from Backports on Debian Sarge

Post date: August 12, 2006, 18:08 Category: Software Views: 3473 Comments
Tutorial quote: There is a great howto about installing Xen on Debian Unstable. It is really easy to do and it runs fine. Nevertheless, on production servers, that's not an optimal solution. Debian Unstable has too many updates and things change too often. On production machines, a Xen host system should be stable, secure and should not need much attention. That is where Sarge comes in. If you pull the Xen packages from backports and install them on Debian stable you've got the best of both worlds. Let's do so!
