One of my Red Hat servers is behind proxy with no access to the outside world. This box is registered to a Satellite server to receive software updates. I want to install Zabbix server on this server using the packages from Zabbix upstream directly. To do this, I need to set the proxy for the Zabbix’s repository. There are a few ways to do this. For my purpose, the best place is to set proxy=proxy_server directly in the .repo file. ...

This post is primarily written to remind myself, an Ubuntu user, to figure out how to find what RPM package provides a file — for example a header file. Today, I’m trying to compile and install R 3.1.3 on CentOS 6 from source code. This R installation is one of the requirements to install Tessera stack. The instruction from the installation page is: Unfortunately, the process failed with ./configure with the complain about missing readline library.
