I spent a week trying this out recently but kept running into problems with openssl libraries, and pre-compiled packages.
I used both an rpm that had already been built for Apache 2 (after creating symlinks to the openssl libraries), and compiled openssl and Apache 2 from source. In both cases I could send one request for a secure page, but all subsequent requests hung completely. Until Red Hat can release an rpm that works with their other rpms I'd suggest that Apache 2 on that platform is still a bit of a pipe-dream. It's now my preference to stay with pre-compiled packages where-ever I can, simply because it is easier for me to administer (but I don't want to start another discussion on that either!) Which brings me to the point. Are you using the packages that came with RedHat 7.2, or compiling your own? In the latter case, you may be seeing conflicts with the openssl libraries that come with Red Hat 7.2. I've had no difficulties with the packages that come with Red Hat 7.2 thus far. - John Airey Internet systems support officer, ITCSD, Royal National Institute of the Blind, Bakewell Road, Peterborough PE2 6XU, Tel.: +44 (0) 1733 375299 Fax: +44 (0) 1733 370848 [EMAIL PROTECTED] If Charles Darwin knew a fraction of what scientists know today, he'd never have written the Origin of the Species. - NOTICE: The information contained in this email and any attachments is confidential and may be legally privileged.
