Server, ruby error #65

Closed Swiffers closed 9 years ago

Swiffers commented 9 years ago

Following your installation manual, with a Droplet from https://cloud.digitalocean.com; I end up with the following error : 

ruby ./dnscat2.rb

I think that's somewhere in the install guide.. you have to install "ruby-dev" or something. I can look it up later. :)

So, that's not the error I was thinking of, the one I noticed looked like:

/usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- mkmf (LoadError)

And installing the "ruby-dev" package worked. It's possible I just have to add "rexec" to the gemfile. If installing "ruby-dev" doesn't help, can you run "gem install rexec" and see if that helps?

Swiffers commented 9 years ago

Issue solved ! As you recommended, the rexec gem solved the problem.

gem install rexec
iagox86 commented 9 years ago

Great! I added it to the Gemfile explicitly.
