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.
