Re: [HTCondor-users] subject: install HTCondor 8.4.0-1 on RHEL 6.2 libcrypto.so.10 error

Hi Jon,

I ran into this myself last year under
RHEL 6.4. I think the issue is that the newer UW build was compiled against
OpenSSL 1.0.1 in the wake of the HeartBleed bug, and while that bug doesn't
affect the 6.0 through 6.4 OpenSSL 1.0.0 series, I think the linker is
still looking for the 1.0.1 release. I think if you upgrade your OpenSSL
package to 1.0.1e-42, which is the current release for RHEL6, that should
satisfy the dependencies. See step 3 at https://access.redhat.com/solutions/781793

Or better yet, just patch your systems
to 6.7. There's gobs of improvements in the intervening releases, including
noticeable performance increases that will improve your pool. Remember,
the Red Hat minor releases are essentially patch bundles like the old Solaris
Recommended & Security bundles, as opposed to the gulf you find between
SunOS 5.9 and 5.10 "minor" release numbers. IT management should
be focused on the "6," not the ".2" or the ".7"
numbers, and errata should be applied on a regular basis.

That said, though, you should also make
sure your various firmware and BIOS versions are up to date beforehand
- a certain HP Ethernet card won't work if you go to 6.5 or higher without
new enough firmware on it, for example, and that's a real hassle when you
have a diskless node.
