maintenance v1.0

the GNU GPL applies - see COPYING for details

Introduction

The following program was developed under Suse Linux 6.4. It should work on almost any distribution of Linux.

Perhaps a port to other Unices like Solaris, FreeBSD, or AIX is possible without many changes. I assume you only need to change the sha-bang to #!/bin/sh to make it work.

This is a simple Bourne Shell script. It mails a report to root about the login (attempts) of the last day. It mails the logs of the Apache Server and a copy of the system log too. The system log is cleared thereafter.

The script should be either invoked daily by crond or by using a script at bootup. This little program includes some code to check the current day. (alright, you could invoke the script once at 23:50 and at 00:01. The script will then think that one day has gone and redo. however, the resulting logs will not contain much usefull information.)
A special feature mails a reminder to a local user to inform me that the maintenance has been done. I'll then login as root to check the reports.
