Note:
ruby-bundled-gems is required for net/ftp, net/imap, net/pop, and
net/smtp. For some reason Fedora’s ruby package does not automatically
install the ruby-bundled-gems package as a dependency of ruby.
Installing Ronin on Fedora
Copy/Paste Instructions
sudo dnf install -y gcc make ruby-devel ruby-bundled-gems git zip nmap masscan graphviz
sudo gem install ronin
Detailed Breakdown
Build Dependencies
First we will need to install a C compiler (gcc or clang) and make. These are required to install certain ruby gems, which contain C extensions (aka C bindings) to other C libraries, such as the nokogiri, sqlite3, and nio4r gems.
sudo dnf install -y gcc make
Ruby
Next, we will need to install Ruby >= 3.0.0, which should already be available in your system’s package manager.
sudo dnf install -y ruby-devel ruby-bundled-gems
Runtime Dependencies
Next we will need to install additional utilities, such as git and zip, that parts of Ronin use:
sudo dnf install -y git zip
Ronin
Now that everything else is installed, it is time to install Ronin!
sudo gem install ronin
Postinstall
Assuming no errors occur, you should now be able to run ronin:
ronin help
Troubleshooting
Ruby and many ruby gems will not work if the LANG environment variable is
not set or set to C. Make sure that LANG is set to a UTF8 language, such as
en_US.UTF-8.
If you get an exception saying cannot load such file -- net/ftp when trying to
run ronin irb or requiring ronin/support in Ruby, this is because the
Fedora ruby-bundled-gems rpm package isn’t installed. You can fix this by
running:
sudo dnf install -y ruby-bundled-gems
