I am trying to install the logstash-codec-nmap, but my server has no internet access.
But when i download to a different server ans then try to install locally:
bin/plugin install /root/logstash-codec-nmap
Unable to download data from https://rubygems.org - certificate verify failed (https://api.rubygems.org/latest_specs.4.8.gz)
ERROR: Installation aborted, verification failed for /root/logstash-codec-nmap
bin/plugin install /root/logstash-codec-nmap-0.0.15.gem
Error Bundler::Fetcher::CertificateFailureError, retrying 1/10
Could not verify the SSL certificate for https://rubygems.org/.
There is a chance you are experiencing a man-in-the-middle attack, but most likely your system doesn't have the CA certificates needed for verification. For information about OpenSSL certificates, see bit.ly/ruby-ssl. To connect without using SSL, edit your Gemfile sources and change 'https' to 'http'.
