- I apologize to everyone for my previous message that got repeated
- about 4 or 5 times.
-
- I promised to find out more about hardware used on other freenets.
- In the NPTN's booklet "The Bluebook: A guide to the Development of free-net
- community computer systems", in the section on hardware:
-
- --------------------
- The freenet software is designed to be transferable to a wide variety of
- computers. On the cleveland system, which is more or less our "flagship", we
- currently happen to be using a mixture of IBM-RT Model 135 computers and Sun
- Sparcstations which are linked together to form a seamless whole. Your
- system will probably not be anything like this size; and you do not necessarily
- have to be using IBM or Sun equipment. The Free-Net will run sucessfully on
- At&T, Sun Microsystems, DEC, and many other kinds of machines. But whatever
- computer you choose, at this time, it must be a Unix-based system.
-
- In general, even for a small town, we would recommend no less than four mb of RAM
- and at least 100 mb of hard disk. In both areas more really IS
- better - especially when it comes to hard disk storage. Get as much as you can.
- The number of phone lines you have will depend on you potential user base. From
- our experience, however, it is difficult to imagine any system that would have
- less than five telephone lines and a large metropolitan area may require as many
- as 30 to 50 or more.
-
- We also feel that the Free_net should be operated on a dedicated machine, that
- is, that it NOT be run on a machine that is carrying other services. The reason
- for this is one of security--both perceived and real. In most cases, a
- multiple-user Unix machine will allow its various users access to the
- "shell"--the basic operating level of the system. Once into the shell it is
- difficult to keep an unscrupulous user user from crossing into the Free-Net area,
- there to possibly tamper with the files, compromise the electronic mail
- accounts, and so forth. This situation can be controlled only if a user can not
- get on the machine at all unless they are entering the Free-Net program. Once
- in the program, the user's options are prescribed and certainly do not include
- shell access. Remember, not only must Free-Net systems be secure, they must be
- perceived as being secure by your user base.

- END QUOTED MATERIAL
-
- I'll put up some more info later on "Software and System Design". If there
- is no discussion here, should this stuff be forwared to the RTPFREENET list?
