Net ssh users - Aug 2005 - cipher-factory.rb raises RuntimeErrors

Hi,
I''m using version 1.0.0 of Net::SSH, which I installed via
Gentoo''s
emerge.  Upon attempting to start a session, I get:

/usr/lib/ruby/site_ruby/1.8/net/ssh/transport/ossl/cipher-factory.rb:74:in
`initialize'': Unsupported cipher algorithm (aes-128-cbc).
(RuntimeError)
         from
/usr/lib/ruby/site_ruby/1.8/net/ssh/transport/ossl/cipher-factory.rb:74:in
...

Many more lines follow, but this is the important bit, I believe.

I have tried using (well, suggesting) other ciphers with no luck.  What
can I do to remedy the situation?

I am using ruby 1.8.2 (the version released on 2004-12-25).  The version
of OpenSSL in use is 0.9.7g.

Thanks,
Forrest

Are the ciphers loaded as external libraries? if so, you may need to
add the path to the libraries to /etc/ld.so.conf and then run (as
root) ldconfig. I had a similar problem of late, albeit with different
libraries.

==================================Woulds''t thou so blame
the fragrant blos''ms wilting
as never to''ve had her bloom?

The only libraries I could think of that might need to be loaded are
libssl, libcrypto, and libcrypt, which are all loaded.

Looking further into this, it seems to be a problem with OpenSSL itself,
and not Net::SSH.  I can''t find a single alorithm that
OpenSSL::Cipher::Cipher.new(alg) will work with, and even the sample
code from the ruby tarball doesn''t work.

ctx = OpenSSL::SSL::SSLContext.new()

Throws me an SSLError, "Library has no ciphers."  Oops!

I''ll look elsewhere for help, sorry for cluttering up the list.  Also,
thanks for the prompt reply!

Cheers,
Forrest

Good Luck Forest, let me know how it turns out.
