Greetings -- We are seeking a means to implement real-time write-once "dropsafe" logs of o ur firewall bastion in case of a system failure or a hacker trying to cover thei r tracks. Unfortunately, unless there's an alternative I'm not aware of, a CD- R requires a complete disk image in ISO 9660 format to be burned into the writeable disk all at once, which means we either have to wait until we have nearly 640 MB of logfiles to write or waste an awful lot of writeable disk space.
You may need to redefine "waste". 30 seconds looking at the Web shows a 3.2G IDE drive for ~$100, and 9G UltraSCSI for $400. Sure, that's not free, and there are other constraints, such as open bays and the like. But it's likely to be cheaper than anything else you do, especially if you count your time. Consider -- for ~$500, you can buy an entire PC, bring up a stripped-down Linux, and have several gig of disk for log space. "Hardware is free; people are expensive".
