Very Computer

Hi,
        I have a need to keep statistics on how many times a service port has been
hit.  For example, I would like to know how many times a POP3 or FTP port session has
been made on a particular machine.  Any suggestions would be appreciated.

                Thanks,
                        Neil :-)

Service Checker, serchk
=======================

   serchk, the service checker, is a Perl script which reads in
   a simple configuration file and checks defined hostnames and
   ports for connectivity.  As you may well have noticed, pinging
   a host does not mean it is usable.  Machines can be completely
   wedged and respond to ping requests just fine.  serchk is useful
   to solve this problem (and hopefully many others) because it
   will connect to a normal interactive port (if you tell it to),
   which is a much more reassuring sign that a host is fully up
   and functioning.  serchk is not limited to connecting to the
   standard telnet port though, read on!

   Usage is as such:

      serchk [config_file]

   If no config file is specified on the command line, /etc/serchk.cf
   is used (see Installation below).

Tested Architectures
====================

   serchk should work fine on any system where Perl 4.03x is installed
   properly.

Installation
============

   Edit the file ``serchk'' and substitute the location of your perl
   binary on line 1.

   Edit the file Makefile in this directory.  See the comments there.

   Type 'make' and follow any steps which show up on your screen as
   a result of this process.

Bugs
====

   The double quote character " is used as a delimiter in the config
   file, and as such cannot be used inside any of the expressions
   currently.

Copyright
=========

   serchk is freely distributable with no modifications.  If you hack
   on serchk at your site, I ask that you do not distribute your code.
