Create a Linux Antivirus Server to Protect eMail - A Brief How to

Does Ubuntu Linux Really Need Antivirus Software?” Where there was a bit of discussion as to whether Linux needed antivirus software installed.spacer_gif Create a Linux Antivirus Server to Protect eMail - A Brief How to

There were some very informative comments from readers, which showed that in reality it would be very difficult to develop Linux based viruses, and that the real use would be to protect Windows users. After some thought and a bit of playing, I was introduced to ClamAV. For those not familiar, their site description says:spacer_gif Create a Linux Antivirus Server to Protect eMail - A Brief How to

…Clam AntiVirus is an open source (GPL) anti-virus toolkit for UNIX, designed especially for email scanning on mail gateways. It provides a number of utilities including a flexible and scalable multi-threaded daemon, a command line scanner and advanced tool for automatic database updates. The core of the package is an anti-virus engine available in a form of shared library…spacer_gif Create a Linux Antivirus Server to Protect eMail - A Brief How to

For me at least, this was a clear challenge to roll up my sleeves and create a small antivirus server (used to scan email). This would be useful to the small business owner, school, club or hobbyists in general. I’m not going to Read the full post…

Upgrading Ubuntu From Edgy to Feisty Fawn

Upgrading Ubuntu From Edgy to Feisty (6.10 to 7.04)

Ubuntu Feisty (7.04) is the latest version of Ubuntu. Here's the quick list of new features for your enjoyment, but you should really upgrade to see everything for yourself.

New in Feisty:

  • Windows Migration Tool - Will help you migrate your user settings, such as wallpaper and bookmarks.
  • Codec wizard - Helps install unsupported codecs
  • Wireless - Greatly upgraded wireless support lets you easily connect to different networks
  • Upgraded Kernel - 2.6.20 kernel supports hardware virtualization features in the newer processors.
  • Upgraded Gnome - Gnome 2.18 has a lot of new features you'll want, including a nice administration panel overhaul.
  • Lots of other stuff!

Note: Before you start this upgrade, you should make sure that you have updated Edgy with all the latest patches using the Update Manager. This will make installation more smooth, and also solve the problems some people are having with not being able to upgrade.

To start the upgrade from Edgy (6.10) to Feisty(7.04), you can hit the Alt+F2 combo to pop up the run box. Enter the following text. Note that the quotes are the normal double-quote.

gksu "update-manager -c"

When the Software updates tool launches, you'll see a new button saying Upgrade. Click it. Now. Or not.

You don't have to read the release notes before you click Upgrade again.

If you get an error message saying that authentication has failed, you will need to type the following command at the terminal prompt:

gpg

Once you get the message about entering your message now, just hit Ctrl+C and then start the install process over. If that doesn't work, you may want to try running a shell as root before running the command ( sudo /bin/bash should do it)
Now you can click Start Upgrade. Seems that we already started the upgrade, but no matter, we'll start it now.

You may encounter more dialogs asking to click Upgrade, if so… click upgrade. Now your system will download all the updates and install them.

All done, restart your computer by clicking the button. At least this button doesn't say Upgrade.

To verify that you are now running Feisty, run the following command from a terminal window. Note that your output might be slightly different.

$ cat /etc/issue

Ubuntu feisty (development branch) \n \l

Check out the new Control Center goodness!

Note: If you are upgrading from Dapper (6.06) to Feisty, you will probably want to upgrade from Dapper to Edgy, and then from Edgy to Feisty.

Update:Modified the article to reflect the Feisty release.

Ubuntu - Linux for Human Beings!

Ubuntu - Linux for Human Beings!

Ubuntu is an entirely open source operating system built around the Linux kernel. The Ubuntu community is built around the ideals enshrined in the Ubuntu Philosophy: that software should be available free of charge, that software tools should be usable by people in their local language and despite any disabilities, and that people should have the freedom to customize and alter their software in whatever way they see fit. For those reasons:

  • Ubuntu will always be free of charge, and there is no extra fee for the "enterprise edition", we make our very best work available to everyone on the same Free terms.

  • Ubuntu includes the very best in translations and accessibility infrastructure that the free software community has to offer, to make Ubuntu usable for as many people as possible.

  • Ubuntu is released regularly and predictably; a new release is made every six months. You can use the current stable release or the current development release. Each release is supported for at least 18 months.

  • Ubuntu is entirely committed to the principles of open source software development; we encourage people to use open source software, improve it and pass it on.
