CentOS 8.2 - cannot load such file -- netaddr (LoadError)

[ghost]

I'm trying to get ssh_scan installed on a default server installation of CentOS 8.2. After running ssh_scan I get: cannot load such file -- netaddr (LoadError). A Google of the error didn't produce an exact answer but the Ruby version is often said to be the cause. Before I try to install another version of Ruby (I'm using the default CentOS package now), I wanted to be sure. These are the installation steps that I've done to take care of the various dependencies.

Installation Procedure dnf install git git clone https://github.com/mozilla/ssh_scan.git cd ssh_scan dnf install ruby dnf install python3-pip pip3 install ipython pip3 install netaddr gem install bundler bundle install

Error $ ./bin/ssh_scan Traceback (most recent call last): 2: from ./ssh_scan:7:in <main>' 1: from /usr/share/rubygems/rubygems/core_ext/kernel_require.rb:59:inrequire' /usr/share/rubygems/rubygems/core_ext/kernel_require.rb:59:in `require': cannot load such file -- netaddr (LoadError)

The strange thing about this error is that the path referenced does exist, so I'm not sure why it cannot be loaded: $ ls /usr/share/rubygems/rubygems/core_ext kernel_gem.rb kernel_require.rb

Ruby Version ruby 2.5.5p157 (2019-03-15 revision 67260) [x86_64-linux]

This is the madness of Ruby dependancy hell. Let me see if I can help...

For a source checkout, I'd advise adding the following after you install bundler:

• bundle install

For docker, it should just work, and satisfy the deps for you.

Let me know if that doesn't solve the problem and we'll figure it out.

I'm sorry. I should have included bundle install as my last step in this bug report, as that was the last step that I preformed before I got this error. I will correct my report and investigate further.

Thank you for the Docker suggestion. I'm happy to help those that don't use it.

I was successful in building from source.
