Hi.

I would like to run a simple command on a remote unix machine from my windows desktop. would this possible in ruby? I would like to run things like a make, ls -l, commands. Has anyone done this before?

You'll likely need a Ruby ssh client
http://raa.ruby-lang.org/project/net-ssh/

Then the rest should be easy:

I've recently looked into using this shh library on Win2k, but have run into a problem. When running even simple code, I get a message box that tells me, "The ordinal 2586 could not be located in the dynamic link library LIBEAY32.dll"

Does anyone know what causes this error, and how to fix it?

I've seen in the net-ssh docs that the code may need a current version of OpenSSL; I think I have that, running the most recent one-click installer of Ruby 1.8.2 on Windows.

Any ideas?

Thanks,

James Britt

Jamis Buck, who just happens to be sitting in front of me here at
RubyConf2004, has informed me that this is an issue related to
openssl.so on Win32, so investigated a bit.

I found this site
http://www.slproweb.com/products/Win32OpenSSL.html

and installed "Win32 OpenSSL v0.9.7d"

I told the installer to overwrite the existing libs when prompted.

I now get different errors, but they make more sense.

But, sadly, this test
ruby -ropenssl -e "p OpenSSL::PKey::DH.instance_method(:g)"

fails, so something is still out of date

What message do you get when it fails?

What version of Ruby are you using? (You said the one-click installer, so I assume you're using the latest-and-greatest.) And do you have OpenSSL for Ruby installed? Last I heard, it did not come with the one-click installer...

I think it is part of the distro now.

I've got a working net-ssh on win32, but I had to compile ruby myself.
the oneclick installer do not have a openssl extension compiled.

  The OpenSSL extension is optionally compiled if the ruby configuration system locates OpenSSL headers and libraries. In other words if your OpenSSL files are e.g in c:\openssl, you have to set
INC environment variable like set INC=%INC%;c:\openssl\include and
LIB environment variable liek set LIB=%LIB%;c:\openssl\lib. You also
have to put c:\openssl\lib to PATH environment variable so that dynamic loader can find them when requiring openssl.so. Once these variables are set correctly, you have to compile ruby sources and hopefully ruby openssl extensionis compiled as well.
