Distributed Storage Across Four Storage Nodes With GlusterFS On Ubuntu 9.10

Post date: January 14, 2010, 01:01 Category: Installing Views: 3452 Comments
Tutorial quote: This tutorial shows how to combine four single storage servers (running Ubuntu 9.10) to one large storage server (distributed storage) with GlusterFS. The client system (Ubuntu 9.10 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.

How To Set Up A USB-Over-IP Server And Client With Debian Lenny

Post date: January 24, 2010, 01:01 Category: Installing Views: 4474 Comments
Tutorial quote: This tutorial shows how to set up a USB-over-IP server with Debian Lenny as well as a USB-over-IP client (also running Debian Lenny). The USB/IP Project aims to develop a general USB device sharing system over IP network. To share USB devices between computers with their full functionality, USB/IP encapsulates "USB I/O messages" into TCP/IP payloads and transmits them between computers. USB-over-IP can be useful for virtual machines, for example, that don't have access to the host system's hardware - USB-over-IP allows virtual machines to use remote USB devices.

Post date: June 6, 2007, 23:06 Category: Security Views: 4230 Comments
Tutorial quote: Say you have a nasty application on your Apache webserver that has been installed by some people from the marketing department and you can neither remove nor patch it. Maybe it is a time problem, a lack of know-how, a lack of source-code, or possibly even political reasons. Consequently you need to protect it without touching it. There is ModSecurity, but they say this is only for experts. A straightforward alternative is Remo, a graphical rule editor for ModSecurity that comes with a whitelist approach. It has all you need to lock down the application.

Monitoring Servers and Clients using Munin

Post date: April 4, 2006, 20:04 Category: Installing Views: 3159 Comments
Tutorial quote: "Munin" means "memory".

Munin the tool surveys all your computers and remembers what it saw. It presents all the information in in graphs through a web interface. Its emphasis is on plug and play capabilities. After completing a installation a high number of monitoring plugins will be playing with no more effort. Using Munin you can easily monitor the performance of your computers, networks, SANs, and quite possibly applications as well. It makes it easy to determine "what's different today" when a performance problem crops up. It makes it easy to see how you're doing capacity wise on all limited resources.

It uses the excellent RRDTool and is written in Perl. Munin has a master/node architecture in which the master connects to all the nodes at regular intervals and asks them for sdata. It then stores the data in RRD files, and (if needed) updates the graphs. One of the main goals has been ease of creating new plugins (graphs).
