概要

SDF(Super Dimension Fortress) Public Access UNIX Systemは、フリーシェルプロバイダーとしては古く、1987年にアメリカ・テキサス州で運営を開始しました。
Ted Ühlemann (iczer), Stephen Jones (smj), Daniel Finster (df) が当時の運営メンバーです。
名前の由来は日本アニメの "超時空要塞マクロス"(The Super Dimension Fortress Macross)です。 当初はアニメファンの為に掲示板を提供していました。
ウェブページへの広告表示はありません。

Shell and UUCP accounts. Online games, 'commode' chat, bboard, napster, icq, programming utilities and much more. Login as 'new' for immediate account registration.

By the Fall of 1992 Ted, Daniel and three SDF users Steven Parker (sp), Steve Linebarger (srl) and Bill Middleton (wjm) had left SDF to form Texas Metronet, Dallas' first (if not in Texas) commercial internet service provider. Stephen remained behind continuing to administer to the SDF.

**limitation and policy**
blockquoteline

The SDF Public Access UNIX System, a 501(c)7 non-profit corporation,
reserves the right to deny access to anyone regardless if the user
has made a donation or paid membership dues. If a user's activities
are interfering with another user or users (on this system or on
another) the user in question will have their account access limited
or possibly removed. Spamming of any sort is not permitted and would
result in account removal. Illegal activities that actively involve
SDF (id est, using SDF to run crack or for guessing passwords and/or
trading copyrighted work) will most likely result in account removal.

The SDF Public Access UNIX System makes no guarantees in the reliability
or preservation of account accessibility, email sent or received,
files uploaded or created by online editing or compilation. That
being said, data loss should only occur during a catastrophic hardware
failure in which critical files would be restored from tape archives.

Members of the SDF Public Access UNIX System are expected to conduct
themselves in an appropriate and reasonable manner when using our facilities.

Lifetime ARPA membership is based on the lifetime of SDF, not
of the user and is non-transferable. SDF has existed since 1987
and with your support maybe it just might out live you. ;-)

Any illegal activities which includes, but certainly isn't limited
to spamming, portflooding, portscanning, irc bots, encryption cracking,
unauthorised connections to remote hosts and any sort of scam can really
not be tolerated here. Why? Because there are many here on this system
that can suffer from this sort of abuse. If you want to use SDF, you
really have to care about this system and the people here. If you don't
want to care, then you really shouldn't use his resource.

I agree with your policy and accept it (yes/no): cursor

FEP Command: teach
[01] CAN MY UNIX CLASS/STUDENTS USE SDF.LONESTAR.ORG?

A number of UNIX classes have been taught using the SDF. From the
basics of getting acqainted with the various shells, commnads and
environment to learning the VI editor, EMACS, sed and awk, SDF is
an extremely flexible learning environment for students and hackers.

perl and python are also available for script programming as well,
your students will have 20mb of storage space to design their own
webpages and even can create their own subdomain based on their login.

Students in active class who wish to validate their accounts may
do so by having their instructor send a list of usernames created
and used by students as well as a copy of the class syllabus.

Access limitations *may* inhibit your class. Please plan ahead and
contact 'smj@sdf.lonestar.org' with any goals or specific needs.

It GREATLY helps us if you would run the 'teach' command once you
have a login account to help let us know how we are doing. Teachers
and students are both welcome to participate in this survey.

While we did initially start out on a single computer in 1987, the SDF is now a network of 8 64bit enterprise class servers running NetBSD realising a combined processing power of over 21.1 GFLOPS!

Our mass storage configuration is comprised of 60 spindles of mostly 36.4gb and a few 9.1gb SCA LVD SCSI drives using DIGITAL Storage Works hotswap disk arrays. We have roughly 2 terabytes of storage online.

We are networked via two sprintlink T1s and a T1 to savvis. We do BGP peering and try out best to load balance between the links via a CISCO 7xxx router/switch. We are using a 'swamp' class C 192.94.73 which has basically been assigned to our site admin along with his class C back when you could request one from the INTERNIC without much fuss.
