This project provides tools to manage configurations for Cisco devices. At the heart of the project is a tftp daemon written entirely in PHP. Configurations are read and written to the tftp server using a file path that incorporates a password feature for security. The current version of each device configuration is stored in a mysql database. Subsequent changes to the configurations are stored in diff format to provide revision history. A web frontend is provided to manage devices and view configurations and history. (more…)

AWStats is a log analyzer for apache logs. It is available at http://awstats.sourceforge.net/.

AWStats consists of a number of perl scripts and related files. There is no build in the sense of compiling required. Even though awstats has been designed as a cgi that creates statistics dynamically it also supports static html pages. I choose to run awstats on a daily basis to generate static pages. No cgi access provided. This eliminates all cgi related security risks and also places the load of processing log information at a controlled time when overall server load is low. (more…)

These instructions describe the installation of a Debian GNU/Linux based mail server. The server is a closed system, without user shell accounts. Mail accounts are administered using web based tools. This provides for excellent system security.

Note that these instructions are based on my installation notes, just prettied up a little. A fair bit of system administration knowledge is assumed. The information concentrates on installation and configuration of components that comprise the mail system. Setting passwords, adding users, configuring networking aren’t touched on and tasks the reader should be familiar with. With that out of the way, enjoy! (more…)

This is the certificate for my CA (This is a new certificate as of October 31, 2004). By adding this certificate to a mail client or browser my ssl secure web pages can be accessed without annoying warning messages. It is also a requirement to us secure POP3, IMAP and SMTP on mail.adis.ca. (more…)

Way back when there was a time when my mail was handled by sendmail, procmail and UW-imapd. I came up with a procmail recipe that would lookup sender ip addresses in various DNSBL services.
