From the JPL Archives!

In this September 1960 photo, Allyn B. “Hap” Hazard wears a space suit he designed. Hap was a Senior Development Engineer in the Missile Engineering Section of JPL in 1959 when he wrote a plan for manned space exploration. JPL was transitioning from missiles to space exploration, and Hap had a lot of ideas about the subject. In March 1961, Hap left JPL to work at Aerojet, and presumably to work on the suit and his other inventions. In addition to the suit, he designed and built a hydrofoil boat and a snow making machine during his time at JPL.

It doesn’t appear that the suit was ever an official JPL project, and very little documentation exists in the JPL Archives except for the photographs and his report, which includes a disclaimer, “The views expressed in this paper are those of the writer ….” The Section 352 online photo album includes a series of photos and drawings of his Lunar Exploration Space Suit Mark 1 and plans for a moonmobile that could be controlled from the dashboard inside the suit.

After Hap left JPL, he and the suit appeared or were mentioned in Life magazine, Boys Life, and the Syracuse Post-Standard. An Experimental Engineering class at UCLA studied the suit, and Mattel created an astronaut toy that wore a replica of it. Even today, there are many web sites that include the story of Hap Hazard, his space suit, and Major Matt Mason (the toy).

OpenAFS is an open source implementation of AFS that works nicely with JPL’s setup. It’s easy to install and quite stable.

Ubuntu:
I’ve tested these instructions in 9.04, 8.10, and even recently in 6.06 (Yes, the apt-get method of maintaining a Linux machine is far superior to using RPMs).

The first step is to build and install the OpenAFS kernel module. The following steps take care of downloading the appropriate software, compiling and installing everything. As usual, this needs to be done as root, or using the sudo command.


$ apt-get install module-assistant openafs-modules-source
$ module-assistant prepare
$ module-assistant auto-install openafs-modules
$ depmod -a


If all of that is successful, your computer should now have the OpenAFS kernel module buit and installed. The next step is to install the OpenAFS client software.


$ apt-get install openafs-client openafs-krb5


Ok, you now have all the software you should need. The last step on Ubuntu systems is to configure OpenAFS per your site. Running the following command will start an interactive program that asks you about your site specific AFS configuration. The most important piece of info you’ll need is your “Cell” name. For us at JPL, it’s jpl.nasa.gov. I’ve found that most of the time, the default responses for the rest of the questions are fine.

Configure OpenAFS:


$ dpkg-reconfigure openafs-client


Installing on Fedora / CentOS / Red Hat:
Unfortunately, installing OpenAFS requires a few more steps on RPM based distributions, but nothing too tough. Mostly, this involves hunting down the appropriate RPMs for your system. I’m using CentOS for this example. For those not in the know, CentOS is basically a free, binary compatible version of RedHat Enterprise Linux. Please visit CentOS.org for more details.

First, you’ll need to locate the appropriate RPMs for your distribution and kernel version. The following RPMs were required on my CentOS 5.3 machines:


$ rpm -qa | grep afs
openafs-1.5.55-el5.1.1
openafs-krb5-1.5.55-el5.1.1
openafs-kmdl-2.6.18-92.1.13.el5-1.4.7-29.el5
openafs-kpasswd-1.5.55-el5.1.1
openafs-client-1.5.55-el5.1.1
openafs-devel-1.4.7-29.el5
openafs-authlibs-1.5.55-el5.1.1
kmod-openafs-1.5.55-1.1.2.6.18_92.1.18.el5
openafs-docs-1.5.55-el5.1.1
openafs-compat-1.5.55-el5.1.1


You can find these RPMs in a few places as none of these distributions provide them for you. First off, ATrpms has them. In the past, I’ve also found them at the main OpenAFS site, OpenAFS.org. Pbone, another third party RPM repository, has OpenAFS rpms that where built for Redhat EL5 here. Those RPMs will work just fine with CentOS 5 too. Lastly, another place to get hard to find RPMs is RPMforge.

Once you have your RPMs installed, then you only have to edit one config file. Populate /etc/openafs/ThisCell with your sites specific cell name. Some smaller sites will have to configure /etc/openafs/CellServDB as well.

Thats it. You should be able to start the OpenAfs daemon (/etc/init.d/openafs start) and then start using AFS.
