The UNIX Finger service can be used to provide a form of user directory service. After you have installed the finger service, remote users will have the ability to query user profiles on your Virtual Private Server. User profiles include information such as full name, login name, home directory, as well as the contents of the .plan, .project, or .forward files. The .plan, .project, and .forward files (if they exist) must be located in each of your users home directories.
To install the finger CGI on your Virtual Private Server you will need to do the following:
You will need to download the Finger Remote User on Remote Host form HTML source and store it somewhere in your ~/www/htdocs directory structure. Feel free to customize the form, add graphics, etc. But be sure that the variable name for each input field is not altered.
Connect to your Virtual Private Server via SSH or Telnet and run this command:
% tar -xvf /usr/local/contrib/finger.tar
This will install the lookup.pl and util.pl files into your ~/www/cgi-bin/library/finger directory.
Two subroutines in the util.pl file are used to print out header and footer information. These functions are print_header_info and print_footer_info. Feel free to modify these functions such that the CGI outputs pages that are in synch with the motifs of the rest of your site.
