Hi,

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  
Validating /root/logstash-codec-nmap  
Unable to download data from [https://rubygems.org](https://rubygems.org) - certificate verify failed ([https://api.rubygems.org/latest\_specs.4.8.gz](https://api.rubygems.org/latest_specs.4.8.gz))  
ERROR: Installation aborted, verification failed for /root/logstash-codec-nmap

Then:-

bin/plugin install /root/logstash-codec-nmap-0.0.15.gem  
Validating /root/logstash-codec-nmap-0.0.15.gem  
Installing logstash-codec-nmap  
Error Bundler::Fetcher::CertificateFailureError, retrying 1/10  
Could not verify the SSL certificate for [https://rubygems.org/](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](http://bit.ly/ruby-ssl). To connect without using SSL, edit your Gemfile sources and change 'https' to 'http'.

Any ideas?

Regards,  
Debarun.

I don't think that is the right command, see [https://www.elastic.co/guide/en/logstash/current/offline-plugins.html#\_install\_or\_update\_a\_local\_plugin](https://www.elastic.co/guide/en/logstash/current/offline-plugins.html#_install_or_update_a_local_plugin)
