Net::SSH difficulties

[Hal Fulton]

I just installed Net::SSH 0.0.3 and started to play with it.

The first simple thing I tried bombed on me.

All info below.

Jamis or whoever else -- thanks for any assistance.


Cheers,
Hal



(This is FC1 and Ruby 1.8.2)

Here's the script (a trivial mod of one of the examples):


require 'net/ssh'

domain = 'WhoWantsToKnow.com'
user = 'hal'
pass = 'yeah,youwish'

Net::SSH.start(domain,user,pass) do |session|
result = session.exec( "ls -la" )
puts result.data
puts "-------------------------------------------"
result = session.exec( "ls -la /" )
puts result.data
puts "-------------------------------------------"
result = session.exec( "echo $HOME" )
puts result.data
end


And here's the result:


/usr/local/lib/ruby/gems/1.8/gems/net-ssh-0.0.3/lib/net/ssh/transport/kex/dh.rb:60:in
`initialize': wrong number of arguments (0 for 1) (ArgumentError)

Hal,

It looks like you're using an unpatched version of the OpenSSL module
for Ruby. One of the changes I submitted to that module was to allow
"blank" keys to be created, and initialized later. Previously, the key
constructors always required at least one parameter.

Can you please verify that you are, indeed, using 1.8.2? (I assume you
mean, by 1.8.2, that you're using a CVS snapshot...?) When did you
install it? Could it be that you are using a version that is "old"
enough that it doesn't include the patch I submitted?

Thanks,

Jamis

ruby -v yields: ruby 1.8.2 (2004-07-08) [i686-linux]

I think this was a nightly snapshot from a couple of weeks ago. I don't
think I got it directly from CVS, but from the (presumably) auto-generated
tgz file.

But that was on top of 1.8.1 -- is it possible that my install is screwed
up somehow?

FYI, I installed ssh via the gem.

I downloaded the patch but decided I didn't need it.

Here's a list of some related files with timestamps. What do you think?

Thanks,
Hal

ruby -v yields: ruby 1.8.2 (2004-07-08) [i686-linux]

I think this was a nightly snapshot from a couple of weeks ago. I don't
think I got it directly from CVS, but from the (presumably) auto-generated
.tgz file.

But that was on top of 1.8.1 -- is it possible that my install is screwed
up somehow?

FYI, I installed ssh via the gem.

I downloaded the patch but decided I didn't need it.

Here's a list of some related files with timestamps. What do you think?

Try this:

ruby -ropenssl -e "p OpenSSL:Key:H.instance_methodg)"

If that gives you an error, then you've got an old version of the
OpenSSL module. Installing on top of 1.8.1 MIGHT have caused problems,
but I wouldn't have thought so. At any rate, if the above works, then
the problem is something else. If it doesn't, then we can take it from
there.

$ ruby -ropenssl -e "p OpenSSL:Key:H.instance_methodg)"
-e:1:in `instance_method': undefined method `g' for class `OpenSSL:Key:H' (NameError)
from -e:1


Umm, I just noticed that the only openssl.so files I have are fairly
old... is the .so supposed to be the same timestamp as the .rb, more
or less?

I would certainly expect the .so to have a similar timestamp to the .rb.
Perhaps the install was borked somehow? At any rate, it looks like
your OpenSSL ruby module is stale.

OK, thanks, I will rebuild and try it again after lunch.

Thanks much,

I'm getting the following errors with OS X 10.3 Panther preinstalled Vim
and the vim-ruby-snapshot-2003-10-12.tar.gz
<http://rubyforge.org/frs/download.php/147/vim-ruby-snapshot-2003-10-12.tar.gz>
vim extensions:

E492: Not an editor command: ^M
...

I'm guessing that the extensions I downloaded have windows line endings,
and I need to strip them. Is there another download I missed?

Thanks,
Nick

More info...

I used tr -d '\r' < ruby.vim > ruby.vim.osx and then renamed for the
syntax, indent, and ftplugin ruby.vim files, and everything seems fine.

Still wondering if I did something wrong, or if later vims handle \n\r
line endings better.

Thanks,
Nick
