Hi list,

Frist of all, I'm very sorry if I bother you all with *another* post on
using openssl, but I'm really tearibng my hair off since a number of
weeks...

As the subject says, I'm runnint CentOS5, I've installed ruby 1.8.6 with
no particular issue.
Rubygems is also installed, with no particular message.

When i try to run the an appication developed with ruby, I get the
following:

[root@wac-srv-pent-03 metasploit]# ./msfweb
./lib/rex/socket/ssl_tcp_server.rb:4:in `require': no such file to load
-- openssl (LoadError)
        from ./lib/rex/socket/ssl_tcp_server.rb:4
        from ./lib/rex/socket/comm/local.rb:5:in `require'
        from ./lib/rex/socket/comm/local.rb:5
        from ./lib/rex/socket.rb:22:in `require'
        from ./lib/rex/socket.rb:22
        from ./lib/rex.rb:71:in `require'
        from ./lib/rex.rb:71
        from ./lib/msf/core.rb:16:in `require'
        from ./lib/msf/core.rb:16
        from ./lib/msf/base.rb:19:in `require'
        from ./lib/msf/base.rb:19
        from ./msfweb:11:in `require'
        from ./msfweb:11
[root@wac-srv-pent-03 metasploit]#


On the CentOS box, the following libs are installed:
openssl   0.9.8b-8.3
openssl-devel  0.9.8b-8.3
openssl-perl  0.9.8b-8.3
openssl097a  0.9.7a-9

I have seen on several posts that I should install libopenssl-ruby1.8,
but I can't locate a version that would run on CentOS.

Help please !!

BTW: I'm not a developer, just a basic user of an application developed
with ruby... please don't shoot at sight if the solution appears to be
dead simple to you guys ....

CentOS system administration, like its Red Hat Enterprise Linux parent,
is *extremely* tricky when you mix packages between what's on the
*official* release media and RPMs or source obtained elsewhere. The
packages on the official release media are tested together and work
together. Moreover, they are updated with security fixes, bug fixes and
enhancements automatically. In short, CentOS/RHEL is a *product*.

I maintain a CentOS 5 / PostgreSQL box and I'm continually wasting time
looking for RPMs, installing packages that I absolutely "must" have,
etc. In all likelihood, you will be better off *not* doing that, and
I've pretty much come to the same conclusion for myself. It's a time
sink with no *obvious* payoff in business results. To paraphrase
Garrison Keillor, "If it isn't on the release media, you can probably
live without it."

What I would recommend, therefore, is that you switch to a more flexible
and "bleeding edge" distro. In your case, since you're used to CentOS,
I'd recommend Fedora 7. Other good ones are Ubuntu, openSuSE, Debian and
Gentoo. That way you can run the latest Ruby, openssl, etc., and have
some confidence that things work together and that you'll be able to get
help on the Fedora community forum network when they don't.

Well, to be honest, I have just been through the exercice of choosing
another distro...
I have been using RedHat for a number of years, and decided NOT to
follow to RedHat5.
Fedora came immediately to mind, but...
I need Linux to run a number of tools (as end-user) under VMware.
As this is is due to be production, the pre-requisites are quality and
stability (performance is not an issue and I build flexibility into VM)
This is exactly how I came to CentOS.
I have spent a significant amount of time installing/configuring/fine
tuning it, and was just trying to get the latest tool installed before
moving the VM to production.

What you are now saying is "throw it all away and start again". Hard to
admit to say the least, but I guess this is the best way to go...
I suppose I will put CentOS on hold and give a try to FC7

Or stay with CentOS 5 and use the Ruby that ships with it, unless
there's some other reason not to do so. If stability is the prime
directive, I don't see any reason why the Ruby on CentOS 5 won't work. I
think it's 1.8.5. Does the CentOS openssl not work with the CentOS Ruby?
