Burning DVDs on Debian for Newbies

Post date: December 23, 2005, 00:12 Category: Multimedia Views: 3160 Comments
Tutorial quote: DVD writers have become so common these days that there is hardly any difference between the price of a CD-writer drive and a DVD-writer drive. So I'm assuming that almost everyone would be buying a DVD writer drive these days. Below are a few tips for newbies on how to burn DVDs on a Debian box using the command line. Other GUI tools like k3b, nautilus burner, etc exists but its always fun to know how to do that stuff from command line.

Tutorial quote: There are a lot of Linux filesystems comparisons available but most of them are anecdotal, based on artificial tasks or completed under older kernels.

Aggregating network interfaces

Post date: February 12, 2006, 07:02 Category: Network Views: 3044 Comments
Tutorial quote: Using more than one hard drive to achieve better performance and fault tolerance is very common. Less well known is that it's also possible to aggregate more than one network interface into a single logical interface. In Linux, this is handled by the bonding driver. Benefits of doing this are much the same as the benefits of aggregating discs using RAID: if one device dies, your server carries on working and by using two devices in parallel, performance can be improved.

FreeNAS is based on the FreeBSD operating system and supports CIFS (samba), FTP, NFS, RSYNC, SSH, local user authentication, and software RAID (0, 1, 5). It comes with a powerful web interface and uses very little space on the hard drive - about 32MB.

Tutorial quote: Suppose you have a 40GB hard disk and a removable hard disk whose capacity is 60GB, and you want to backup all the files from the hard disk to the removable disk. With "dd", it is a very easy task. Again, suppose your hard disk's Unix device name is /dev/sda and the removable disk is /dev/sdb. The following command can copy all the content from /dev/sda to /dev/sdb:

TrueCrypt Tutorial: Truly Portable Data Encryption

Post date: July 2, 2007, 23:07 Category: Security Views: 3556 Comments
Tutorial quote: TrueCrypt is a free software that encrypts data on-the-fly. Right now the newest version released is version 4.3. You can create an encrypted hard drive, a separate partition or a directory with TrueCrypt. It does not simply encrypt the content of files, but their names and the names of the directories they are in as well. Moreover there is no way to check the size of the encrypted directory/HDD/partition. TrueCrypt is available for Windows and Linux.

Install SquidGuard on Smoothwall

Post date: April 12, 2005, 18:04 Category: Software Views: 10856 Comments
Tutorial quote: squidGuard describes itself as: "An ultrafast and free filter, redirector and access controller for Squid". In my experience, it is the ideal web filter for use with Smoothwall and IpCop since it is lightweight and easy to set up. I use it on an i486, 33Mhz system with 18Mb of Ram and 500Mb of hard drive - and while there is a minor performance hit, the hit is not significant.

This simple how-to describes the steps I took to install squidGuard on my system - it should work for yours too.
