I need to run the application dnssec-keygen which uses /dev/random to generate keys for signing domain name server transactions. If I run it on any of the FreeBSD systems I have set up which are all running Version 4.5 or 4.7, this application hangs due to lack of entropy, or at least that is one reason. I was directed to use rndcontrol to turn on various interrupts in the random number generator such as the keyboard and IDE controller interrupts and the system would start to build an entropy pool. Rndcontrol showed me that there were no interrupts being sampled right now so I told it to look at IRQS 3, 14 and 15. the man page in section 4 for random mentions a seed to get everything started, but I can't seem to find any other information to cause /dev/random to spit out data yet. The dnssec-keygen application still hangs so I am obviously missing some step. /dev/random does exist on the systems in question and seems to return a null which is not what it is supposed to be doing. What else should I look at? Thank you. Martin McCormick To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
