Hi, I'm not able to install logstash jdbc static plug-in... While installing it gives message.. fetching specs from [http://rubygems.org](http://rubygems.org) does 10 attempts and then fails. I even downloaded the plug-in,built it and then tried to install but no luck. I also changed the source in gemspec to a local site before buildong but no luck. Can you please help? Thanks in advance.. ---

Please paste the console output of the online install here (the part showing the 10 attempts). ---

Did you try this again or is the above from the previous attempt? ---

Is [rubygems.org](http://rubygems.org) blocked by your DNS resolver? ---

No. I can access it via internet. ---

One the same machine? A download and manual install might also fail if the install process is trying to get dependencies from [rubygems.org](http://rubygems.org) as well. Try a ping to that domain from the LS machine. Logstash has an offline plugin install mechanism. On a different machine with LS installed (at the same version) that has full access one prepares an off-line package (zip file, plugin with deps) that is then copied to the machine without full access and installed.

I can access [rubygems.org](http://rubygems.org) from the same machine. I'll check about offline packages and get back to you. Thanks ---

Hi @rohitjejurikar were you able to install the plugin. I tried building the gem file but the filter was unable to find the derby jar files. ---

Hi, Yes. I was able to install the plug-in. The proxy server was blocking the installation. After we enabled [rubygems.org](http://rubygems.org) I could install the plug-in. ---

Okay, we also have successfully installed the plugin, however, we are using posrgres as loader db. And the version of jar we are using is not compatible with the jar we are using. Which db are you using? And is there some page or documentation where its written which jar to use? ---
