Freenet Installation and Administration
Properly set up, a Freenet node shouldn't need any ongoing administration. However, there are a few automatable tasks that need to be done. First of all, the log files need to be rotated. Secondly, you'll want to restart the Freenet software periodically. Currently the disk (and I believe memory) usage of Freenet tends to balloon unless you restart your node periodically. Both rotating the log files, which requires restarting the node anyway, and restarting the node can be easily done with the script restart_script (shown in Listing 1). For your average node, restarting once a week should be fine.
IBM's JDK is probably the easiest JDK to install. It's precompiled and works, plus it's one of the faster JDKs out there. On the downside it's proprietary and requires registration to download. Both tarball and Red Hat RPMs are available at: www.ibm.com/java/jdk/linux130/index.html.
Kaffe, the OpenSource JDK, is another, more difficult option. You will have to compile in gmp support, something most distributions don't do in their Kaffe packages. A Debian package for Kaffe with gmp support is available from Mr. Bad's site, above. Otherwise, compile from anonymous CVS or a source package to which you apply the patch found in the Freenet README. Make sure you enable gmp support with the --enable-gmp option when you run ./configure.

Free Webinar: Hadoop
How to Build an Optimal Hadoop Cluster to Store and Maintain Unlimited Amounts of Data Using Microservers
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.
Some of key questions to be discussed are:
- What is the “typical” Hadoop cluster and what should be installed on the different machine types?
- Why should you consider the typical workload patterns when making your hardware decisions?
- Are all microservers created equal for Hadoop deployments?
- How do I plan for expansion if I require more compute, memory, storage or networking?
