Appendix A - Set-up and Configuration:

We want a nameing convention for the various machines.

Remember that IP addresses are assigned to network controllers, NOT to machines. While academic with most machines, this distiction will be key when talking about firewall machines (which will have at least two IP addresses).

Do note that in the above we the machines have been identified by function. Some machines may end up doing more than one function (ie: admin mail may be done off of the testbed), and some functions my be spread across more than one machine (ie: news may be split between two or more machines).

Appendix B - Connector/cable standards:

What follows is the sort of utility info. that seems to be needed in the oddest of places.

IBM PC/PC compatible serial port - DB25 male:

IBM PC/PC compatible serial port - DB9 female:

Notes: When dealing with an IBM PC/PC compatible you may find yourself having to deal with a DB-9 and/or DB-25 port(s).

To wire a typical PC <-> Hayes compatible DB-25 modem cable do the following:

9 pins25 pins

The above cables are readily available at almost all PC oriented computer shops in Metro.

Amiga Serial Port except the Amiga 1000 - DB25 male, Amiga 1000 - DB25 female:

22Ring Indicator

Note: On all Amigas except the Amiga 1000, you can use a typical IBM PC standard serial cables in most applications (the only typical application that will cause problems is sound, as the Amiga can handle both a serial connection and sound off the same port, sound being run on normally unused pins). In the Amiga 1000 the addition of a male-male gender changing adaptor will let a standard PC style serial cable be used in most cases.

A typical Amiga - Hayes modem cable would be wired the same as the IBM PC DB-25 connects listed above.

Macintosh / Newton - mini 8 DIN connector

A typical Mac/Newton <-> DB-25 Hayes compatible modem cable would be set up as follows:

Mac PinModem PinMac PinModem Pin

With the above, the modem must be set to ignore the data terminal ready signal (on many Hayes compatible modems this can be done with the command AT&D0).

Atari ST series, Falcon - DB-9/DB-25

Same as the IBM PC pinouts. The original STs were limited to a max. of 19,200 BPS (there are upgrade kits that will allow this to be changed to 57,600 BPS). If a TT or MegaSTE is connected to a LAN via the 8-pin LAN port, serial ports 1 and 2 are disabled. On the MegaSTE and TT modem 1 serial connector has limits re: top speed, and modem 2 serial port has signals missing, plus DTR and RTS are always active.
