Here's an update to the OpenSSL explosion:
I got Nessus to compile but now the SSL connection between the NessusWX client and the RH9 box is very flakey. I will disect this problem and see if I can get around it. Bottom line, if you want to run Nessus, stick with RH 8.0 or older - for now at least.
I'd be happy to post screen shots but I can't until Monday morning.
