I am trying to install logstash-filter-de_dot plugin with below command.
/opt/logstash/bin/plugin install logstash-filter-de_dot
But it shows below error.
Unable to download data from https://rubygems.org - SocketError: initialize: name or service not known (https://rubygems.org/latest_specs.4.8.gz)
ERROR: Installation aborted, verification failed for logstash-filter-de_dot
my logstash version is logstash 2.1.3
What am I missing?
