LTSP 5.2 released, with some impressive features

The Linux Terminal Server Project team have released version 5.2 after two years and almost one thousand commits. It has become one pretty powerful product! I like the ability to “run the whole session remotely or run select applications locally to use specific hardware or advance 3D capabilities.”

Neat.

Script for configuring ClamAV server on Fedora

In short, I’ve written a bash script (available from github) for configuring and removing instances of clamav-server on Fedora. It lets you create and remove individual instances with a specific user and port (if you specify them) and will install the required packages if not already present on the system.

In long, we use Clam AntiVirus as our antivirus protection for Digital Preservation Recorder and talk to it over the default port, 3310.

Installing the clamav-server package under Fedora however, doesn’t actually set up an instance. In fact, it doesn’t copy any system configuration files into place at all. This means that the system is left without any working ClamAV server out of the box.

Under Fedora, ClamAV server is configured on a per user basis. This is actually quite important (unless you run as root) because the daemon needs at minimum read access (and we’ve found also write) on the files/directory being passed for scanning.

The instructions on how to configure it are located under /usr/share/doc/clamav-server-[version]/ but I have taken these instructions and written a bash script to configure all of this for you.

The script is available from github. It can create or remove an individual instance of clamav-server using a specific username and port (if you want to specify them, else it defaults to clamav on port 3310). The script will also install any required packages, if you don’t already have them on the system.

Hopefully this is useful to someone else out there and not just us :-) If you find any bugs feel free to let me know.

More jackalope than jaunty

We have some IBM x3650 servers at work with Adaptec 8k ServeRAID controller cards and SAS drives.

For the life of me I can’t get Jaunty to boot on the machines. It installs just fine, but the initial reboot fails to find the root device and drops me to an “ash” shell which doesn’t ever actually appear. The keyboard also doesn’t work.

It doesn’t matter what RAID array I have, whether I’m using LVM or a standard partitioning scheme with an msdos partition table.. it just doesn’t work.

I’ve added aacraid and several other modules to the initramfs, still no joy.

Add the fact that the machine takes 10 minutes to boot each time I want to test a small change and it’s one super frustrating situation.

Oh, and 8.04 LTS works just fine.

One bug which appears to be a grub issue that I don’t have, which hasn’t been touched since April. There’s another about being unable to find the root device that also hasn’t received any love.

If anyone has some suggestions (install Debian?), let me know. The reason I’m using Ubuntu is because we have a local mirror and Jaunty because it’s a virtual machine and KVM is the way I want to go.

Update: Ahh, problem resolved and it was my fault. See comments..
