How To Set Up A USB-Over-IP Server And Client With Mandriva 2010.0

Post date: April 13, 2010, 11:04 Category: Installing Views: 5356 Comments
Tutorial quote: This tutorial shows how to set up a USB-over-IP server with Mandriva 2010.0 as well as a USB-over-IP client (also running Mandriva 2010.0). 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.

Flexnet License Monitoring With rrdtool

Post date: July 15, 2010, 11:07 Category: Miscellaneous Views: 6881 Comments
Tutorial quote: Some of you may know the commercial Flexnet Licencing Application (İMacrovision). It's a client-server based solution for managing the usage of socalled Flexnet-enabled applications. You can hold licenses of more than one product on one license-server. As you typically have to buy licenses and licenses can be expensive it would be nice to have a monitoring solution to see the utilization of the precious licenses, whether they are underutilized (so money is wasted) or are always fully utilized (so that you can suspect that sometimes people cannot do their work, or only delayed) which is also a waste of resources. As far as I know there are commercial applications for performing such reports, but again you have to spend money. Why not build a simple system yourself, which shows the actual and past usage in an "MRTG style"?

Nginx HTTP Server + PHP5 (With fast-cgi And xcache) On Ubuntu Feisty Fawn

Post date: October 10, 2007, 10:10 Category: Installing Views: 5070 Comments
Tutorial quote: Nginx HTTP Server + PHP5 (With fast-cgi And xcache) On Ubuntu Feisty Fawn

This HowTo describes the implementation of Nginx with php5 support (through FastCGI). The fast-cgi process will be initiated via spawn-fcgi. Nginx is a great replacement of Apache with very low memory footprint and contrary to Lighttpd, does not suffer from memory leak over time. You can then use all the memory left to unleash the power of mysql for instance by increasing the default query cache.

Running A File-, Print-, Proxy-, DHCP-, AND Time-Server For Small/Medium Enterprises

Post date: October 18, 2006, 18:10 Category: System Views: 4798 Comments
Tutorial quote: This article shows how to run a file-, print-, HTTP proxy- DHCP-, and time server for small and medium enterprises (SME) on one single Debian Sarge system. It is very easy to set up, and management is done with an easy-to-use web interface called eBox so once the system is set up, you can forget about the command line. eBox was developed to administrate advanced services for corporate networks, and it was created for Debian Sarge.

Openfiler 2.3 Active/Passive Cluster With Offsite Replication Node

Post date: February 10, 2011, 14:02 Category: Installing Views: 5457 Comments
Tutorial quote: Openfiler is a Linux based NAS/SAN application which can deliver storage over nfs/smb/iscsi and ftp. It has a web interface over that you can control these services. The cluster we build will consist of two nodes replicating each other and taking over services and storage in case of emergency. Furthermore we have an Offsite Replication Server, which ideally stands in a physically different position and replicates the configurations/storage from which ever node is active. In case of emergency this Offsite Replication Server can be used to restore the cluster and to deliver the services.

Installing FreeNX Server on SUSE 10

Post date: December 27, 2005, 15:12 Category: Network Views: 8015 Comments
Tutorial quote: Not long ago, I reviewed SUSE Linux 10 and found that they had included the latest version of FreeNX (a free version of NoMachine's NX Server) on the installation media. I'd never really tried FreeNX at that point but had heard some good things about it, so I thought I'd give it a shot. Well, once it was installed and working I have to say I was immediately impressed by how simple it was to setup and how well (read: fast) it performed over a WAN connection. I was literally able to get my desktop at home from anywhere else in the world and get near-local speed. Normally, working on a remote system is alright until you need to type in any shape or form. There was almost no delay from the time I'd press a key to the time it would show up on the screen. This is what sold me on FreeNX and prompted me to offer to write a HOWTO on the topic. I was overwhelmed with email from our readers asking that I write it... so here we are!

High-Availability Storage With GlusterFS On Ubuntu 9.10

Post date: January 10, 2010, 15:01 Category: Installing Views: 3807 Comments
Tutorial quote: This tutorial shows how to set up a high-availability storage with two storage servers (Ubuntu 9.10) that use GlusterFS. Each storage server will be a mirror of the other storage server, and files will be replicated automatically across both storage servers. 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.

Cleaning up a Debian GNU/Linux system

Post date: November 25, 2006, 08:11 Category: System Views: 4243 Comments
Tutorial quote: You arrive at a Debian GNU/Linux server which has some history of neglection. Let's suppose someone else neglected it but if your new-year resolution is to stop neglecting your beloved server, this applies as well.

One form of neglection is to install, install, install and never un-install any package. The common utility to perform installation and un-installation of packages is apt-get which adds to the problem because it doesn't have automatic removal of non-needed dependences.

That means that when phpMyAdmin was installed it also installed Apache, PHP and ton of other packages. phpMyAdmin was removed when it was no longer needed but Apache, PHP and the ton of packages remain there.

Aptitude to the rescue.
