Run Your Own Webradio Station With Icecast2 And Ices2

Post date: February 18, 2007, 20:02 Category: Multimedia Views: 4752 Comments
Tutorial quote: This tutorial describes how to set up an audio streaming server with Icecast2. In order that Icecast2 can stream audio to listeners we install Ices2. Ices2 is a program that sends audio data to an Icecast2 server to broadcast to clients. Ices2 can either read audio data from disk (Ogg Vorbis files), or sample live audio from a sound card and encode it on the fly. In this article we will let Ices2 read .ogg files from the local hard disk.

List of BitTorrent clients Available in Ubuntu Linux

Post date: August 12, 2008, 06:08 Category: Software Views: 3275 Comments
Tutorial quote: BitTorrent is a peer-to-peer file sharing protocol used to distribute large amounts of data. The initial distributor of the complete file or collection acts as the first seed. Each peer that downloads the data also uploads it to other peers. Relative to standard internet hosting, this provides a significant reduction in the original distributor's hardware and bandwidth resource costs. It also provides redundancy against system problems and reduces dependence on the original distributor.

A BitTorrent client is a program that manages torrent downloads and uploads using the BitTorrent protocol.

Remote backup using ssh, tar and cron

Post date: April 13, 2005, 01:04 Category: Miscellaneous Views: 2856 Comments
Tutorial quote: Are you looking for a solution to backup your data to a remote location? While a solid backup solution such as Arkeia or TSM from IBM are nice from an enterprise point of view, simpler solutions are available from a home user's perspective. I will walk you through on you how you can backup your data to a remote server, using the default tools available on all linux systems. In a nutshell, we will use ssh capabilities to allow a cron job to transfer a tarball from you local machine to a remote machine.

For the purpose of this tutorial, the local machine will be called “localmachine” (running slackware) and the remote server will be called “remoteserver” (slackware as well). The user will be joe (me). You will have to substitute those 3 with your own machines names and user.

Installing and securing Squid

Post date: March 13, 2006, 15:03 Category: Software Views: 4771 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.

Striping Across Four Storage Nodes With GlusterFS On Debian Lenny

Post date: July 12, 2009, 10:07 Category: Installing Views: 3231 Comments
Tutorial quote: This tutorial shows how to do data striping (segmentation of logically sequential data, such as a single file, so that segments can be assigned to multiple physical devices in a round-robin fashion and thus written concurrently) across four single storage servers (running Debian Lenny) with GlusterFS. The client system (Debian Lenny 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.

Sawing Linux Logs with Simple Tools

Post date: April 14, 2005, 12:04 Category: Security Views: 2704 Comments
Tutorial quote: So there you are with all of your Linux servers humming along happily. You have tested, tweaked, and configured until they are performing at their peak of perfection. Users are hardly whining at all. Life is good. You may relax and indulge in some nice, relaxing rounds of TuxKart. After all, you earned it.

Except for one little remaining chore: monitoring your log files. [insert horrible alarming music of your choice here.] You're conscientious, so you know you can't just ignore the logs until there's a problem, especially for public services like Web and mail. Somewhere up in the pointy-haired suites, they may even be plotting to require you to track and analyze all sorts of server statistics.

Not to worry, for there are many ways to implement data reduction, which is what log parsing is all about. You want to slice and dice your logs to present only the data you're interested in viewing. Unless you wish to devote your entire life to manually analyzing log files. Even if you only pay attention to logfiles when you're debugging a problem, having some tools to weed out the noise is helpful.
