I got this email from Paul Prescod:
Don't be so sanguine about SOAP security. It could have been designed NOT to use port 80 and NOT to look like HTTP traffic. It was clearly designed to camoflage itself as Web traffic. It would have been easy to send it over sockets and another port. You say that any solution would have security issues. Well yes, everything networked has security issues, but SOAP's very generic RPC design encourages problems like the SOAP::Lite dispatch problem. Some people are writing programs to wrap any COM object in SOAP. Standard application protocols like HTTP and SMTP strongly encourage you to build an abstraction layer that maps from the worlds they talk of "resources" and "mailboxes" to the implementation world: "objects". SOAP does not encourage the introduction of that mapping layer. In fact, standard SOAP/WSDL tools encourage you to take existing code and "generate" a SOAP/WSDL interface to it. Three examples: Visual Studio.NET, axis "java2wsdl" and SOAP::Lite.
Well said. People who know something about security are saying that the nature of Soap makes it especially fertile grounds for security vulnerabilities.
I said, "I believe Dave when he says that Soap wasn't explicitly designed to go through firewalls." But my point here is that it doesn't matter. The intent of the designers is irrelevant, unless they did careful work to make Soap security as good as it could have been. I see no signs of such work.
I need to buy a fast machine, in large part to run the Ghostscript regression tests. By far the best bang for the buck appears to be a dual Athlon. A Tyan Tiger MPX motherboard, two MP 1900+ Atlha, half a gig of RAM, and a disk costs less than $1000 in parts, as listed on PriceWatch.
It's been a while since I put a machine together myself. I'm a little apprehensive, because I know it will take a nontrivial amount of time, and there's a chance it won't work right when I do get it together. I'd rather pay somebody else to do it. Unfortunately, the big name PC's don't do a good job providing this kind of machine. Is there a smaller shop that can do this? Last time around, I bought a dual Celery from The Computer Underground, which was great, but they're not in the box biz anymore.
Alternatively, is there an Advogatan who can do a good job building such a box and putting Debian on it, and who'd like to make a couple hundred bucks?
Otherwise, I'll just order the parts and hope for the best. It doesn't look that hard, and I can probably get some help on the hardware side locally.
I'm also interested in hearing recommendations and anti-recommendations from people who have gone this route. My friend at the coffee shop suggests a water-cooled case as a way of cutting down noise. Is this reasonable?
