Update Added the openssl-snapshot-20040726.tar.bz2 path to Ruby 1.8.2
stable
and I still get the same errors as listed above

using Net::SSH 0.1.0 the above example works

However the above example code does not work with Net::SSH 0.6.0
the above example code is straight out of the Net::SSH documentation
by the maintainer of the project Jamis Buck
any ideas anyone ???......

Yup, this is a bug that has been fixed and will be rolled out in the
upcoming 0.9 release.

The bug occurs because the code always tries to use the agent, even
when no agent is running (or, in your case, when no agent is
needed--you're giving the password explicitly). You can work around
this by doing the following:

Net::SSH.start( 'host', port, 'user', 'password',
:auth_methods => "password"
) do |session|
...
end

In other words, if you explicitly specify the authentication method
you want to use, the agent will never be attempted.

The next release should (hopefully) be ready by late next week, or the
week after that at the VERY latest. (I'm going to be pretty busy this
week, so we'll see what happens.)

Incidentally, if you want to play with the latest version of the code,
it is now being hosted in a subversion repository:

Jamis,

thank you for the detailed response
and thank you for the code work around

i will checkout the latest version and test that

i utilize your net-ssh module in a production env to automate a
bazillion tasks and to monitor various
systems

currently i reverted to past known working version of the module
so my scripts still function
your work is greatly appreciated on this project!!!

Ah, a guinea pig! I would certainly appreciate your continued bug
reporting, in that case. You can always ask questions to this list,
but bugs for Net::SSH should also be reported to the bug tracker at
http://rubyforge.org/projects/net-ssh so that they don't get missed.

Good plan. Not that 0.1 is any more stable, in general, than 0.6, but
hopefully the upcoming 0.9 will be more stable than either of those
releases.

your work is greatly appreciated on this project!!!

Thanks!
