 Top level  Technology
| Wizzy Digital Courier relies on standard networking protocols for the interactive portions, linked by UUCP - Unix-to-Unix-Copy - for the intermittent sections. |
Our software is based on RedHat Linux, currently version 8.0. Though the software can be used for individuals and businesses, for explanation purposes below I will assume a school installation.
There are two 'locations' the software is installed - the school, and the place that has full access to Internet, which may, or may not, be the school. I shall call this place the 'Server'.
At the school, we have the following setup (all Redhat - RH8 plus several RPMs I have packaged) :-
- 'Wizzy' server - 200+Mhz, 256M RAM, 40Gig RAID 1 disk
- DHCP, TFTP for booting
- LDAP for Authentication
- UUCP for /all/ communication
- BIND for nameservices, on local network
- LTSP packages for Thin client NFS-mounted root directory
- Courier IMAP server for inbound mail +webmail
- exim for outbound mail
- wwwoffle as local web cache, some custom programs
- apache webserver for simple Intranet stuff and webmail
- vsftpd for a local FTP server
- dialup to any ISP, but mail goes through my server in Cape Town using UUCP.
- Home directories to be NFS-mounted off Thin Client servers
- RAID disk system
This holds all our custom software, and the important data, like mail and Home directories.
I have the following packages installed :-
- dhcpd
- bind
- openldap
- openldap-clients
- openldap-servers
- last (to edit the LDAP database)
- courier
- courier-imapd
- courier-ldap
- courier-webmail
- aspell (to spellcheck webmail)
- aspell-en-gb
- pspell
- exim (for sending mail)
- ltsp_core
- ltsp_floppyd
- ltsp_kernel
- ltsp_x_core
- tftp-server
- talk-server
- telnet-server
- uucp
- vsftpd
- xinetd
- wwwoffle
If the school is handling its own network installation, desktops, etc., maybe Windows, this is the only server.
In a Thin Client school setup, another machine is needed to host all the user applications - the Thin Client server.
- One or two Thin Client servers - 1.4GHZ -> 2.4GHZ, 1 Gig RAM
- /home mounted off wizzy server
- xfce Window Manager
- Authentication via LDAP on wizzy server
- No user data.
Packages installed here are desktop apps selected for school use.
We have the following packages installed.
Many of those RPMs come with Redhat 8.0 and later - others my be found on my ftp site.
