ctags -R * Not Working [RESOLVED]

I was working on few c programs and wanted to create tags

$ ctags -R * 

// To create tags - recursive all the directory it did not work, it gave the below message

ctags: skipping client: it is not a regular file.
ctags: skipping doc: it is not a regular file.
ctags: skipping etc: it is not a regular file.
ctags: skipping expat: it is not a regular file.
ctags: skipping html: it is not a regular file.
ctags: skipping man: it is not a regular file.
ctags: skipping server: it is not a regular file.
ctags: skipping inclusion of tags in self.
ctags: skipping tests: it is not a regular file.

Then I checked the version I found that I was NOT running exuberant-ctags

ctags (GNU Emacs 23.1)
 Copyright (C) 2009 Free Software Foundation, Inc.
 This program is distributed under the terms in ETAGS.README
 
-R, --no-regex
           Don't  do  any more regexp matching on the following files.  May
          be freely intermixed with filenames and the --regex option.

 Just run the below command

$ sudo apt-get install exuberant-ctags

Installing Zabbix Version 2.4 Offline (Zabbix Server without Internet).

There might be situations where you have a remote/zabbix server which does not have internet connectivity, due to security or other reasons. So we create a custom repo on the remote/zabbix server so that we can install zabbix using rpms Here is how we are planning to do this. Download all the dependency rpms on a machine which has internet connection, using yum-downloadonly or repotrack . Transfer all the rpms to the remote server. Create a repo on the remote server. Update yum configuration. Install. NOTE: This method can be used to install any application, but here we have used zabbix as we had this requirement for a zabbix server. Download dependent rpms . On a machine which has internet connection install the package below. And download all the rpms . Make sure the system are similar (not required to be identical - At-least the OS should be of same version) mkdir /zabbix_rpms yum install yum-downloadonly Downloading all the rpms to location /zabbix_rpms/ ,...
