Frequently Asked Questions (FAQS);faqs.204
There are two sub-domains: msg.uvm.edu belongs to Mach Systems Group,
a group of graduate students involved porting operating systems (most
notably, Mach 2.5 and 3.0) to local hardware; and med.uvm.edu belongs
to the UVM School of Medicine, which is not very well networked as
yet.
Univ. of Virginia:
More or less all students, faculty, and staff can have
accounts that at least receive mail, but most people don't
ever bother to get or use an account. People in the School of
Engineering are most likely to be accessible via e-mail. The
school's primary connections are Internet links to SURAnet
(local NSF Regional network), but there is also a single
BITNET link. Almost any user can be located using the
Internet standard whois program and the whois database that
is kept on the system named: whois.virginia.edu
You can also try fingering lname@virginia.edu.
Univ. of Washington, Seattle:
CS Grads and Faculty: lastname@cs.washington.edu
Most folks are on milton.u.washington.edu, which is the same as
u.washington.edu. Usernames can be anything. Mail sent via
u.washington.edu will forward to the appropriate account.
CS students, grads, and faculty can generally be looked up by last
name at cs.washington.edu; if not, try june.cs.washington.edu for
grads and faculty, and wolf.cs.washington.edu for undergrads.
Univ. of Waterloo, Ontario:
Userids are of of the form <initials>+<surname> (e.g. mbmulroney, ghwbush),
and may be any length (for most machines; some still restrict them to
8 characters. Mail servers send you back a list of possible userids
if the one you tried doesn't match any known user.
Math/CS undergraduates: undergrad.math.uwaterloo.ca
CS graduate students: neumann.uwaterloo.ca
CS and Math Graduate Students: violet.uwaterloo.ca and jeeves.uwaterloo.ca
CS faculty may be found on one or more of the primary machines
{watdragon, maytag, watcgl, daisy, jeeves, grand, poppy, vlsi, watmsg,
math, watserv1}.uwaterloo.ca (there are lots more)
Engineering undergraduate students: userid usually of form
<surname>+<initials> or <initials>+<surname>, at one of
{chemical, civil, electrical, mechanical}.watstar.uwaterloo.ca
Also try @1302 and @108 for chemical, civil, electrical and mechanical
engineering -- these are used mainly for lower-year students
from all engineering departments.
Systems Design Engineering: watnow.uwaterloo.ca
Physics students: physics.watstar.uwaterloo.ca.
Art Students: artspas.watstar.uwaterloo.ca.
Univ. of Western Ontario, London, Ontario:
Computing and Communications Services operates a campus directory
service as well as a campus E-mail forwarding service. This covers
all of the faculty and staff listed in the campus telephone directory
as well as many students. Registration is voluntary but for faculty
and staff is reasonably complete and accurate.
% whois -h whohost.uwo.ca name
eg. whois -h whohost.uwo.ca smith
eg. whois -h whohost.uwo.ca j.smith
eg. whois -h whohost.uwo.ca john.smith
The mail forwarding service works for common names as well:
% mail common-name@uwo.ca
eg. mail smith@uwo.ca
eg. mail j.smith@uwo.ca
eg. mail john.smith@uwo.ca
Mail will either be forwarded to the user with that common name, or
if the name is not unique, you will receive a returned message listing
all users with that common name.
Univ. of Wisconsin/La Crosse:
username@uwlax.edu
Usernames are arbitrary. Try fingering by the lastname.
Univ. of Wisconsin/Madison:
Phone book server (staff only): finger lname@wisc.edu
CS: cs.wisc.edu
Engineering: cae.wisc.edu
Undergrads: Class accounts based on first and last name,
@garfield.cs.wisc.edu.
For other departments, you can sometimes guess the hostname
from the department name. Thus: meteor.wisc.edu for
Meteorology, math.wisc.edu for Mathematics.
Univ. of Wisconsin - Milwaukee:
Many students - csd4.csd.uwm.edu, convex.csd.uwm.edu
EE ugrad and grad - ee.uwm.edu
CS grad - point.cs.uwm.edu
CS fac - blatz.cs.uwm.edu
Students taking Comp Sci Classes: miller.cs.uwm.edu
In fact if you finger cs.uwm.edu you get:
Computer Science users at UWM are normally on workstations or
other backbone computing machines. To locate a faculty member,
graduate student or undergraduate student, you can use the
finger program.
The finger program can help you locate a user who is known to the CS
machines at UWM. To locate a user do
finger person-X@cs.uwm.edu
Where X=F|f if the person is a CS faculty member
X=G|g if the person is a CS grad student
X=U|u if the person is a CS undergraduate student
X=E|e if the person is an Engineering student
X=O|o Other University machines(Just some of them!)
Undergraduates are for the most part on miller.cs.uwm.edu. Graduate
students are usually on cvax.cs.uwm.edu. To get a complete list of
cs-faculty, finger csfac@cs.uwm.edu.
Univ. of Wisconsin - River Falls:
uwrf.bitnet
Utah State University:
cc.usu.edu - This is the MAIN VAX. A Vax 6510 that is usually the
system that everyone uses for most purposes. Our
usenet news is on this computer as well as other
utilities. This is also the system that is a bitnet
node (USU). So mail can be sent to usu.bitnet as well.
mua.usu.edu - This is our Micro-VAX that is running ultrix. Because
this is the popular domain for TinyTALK and TinyFUGUE
programs, the active Gamers use this system.
You can finger both systems, the account names are given in a random
fashion that consists of a five letter code. The first two
letters usually denoting whether the user is a student or a
faculty member. SL___ account belong to students and FA___
accounts belong to faculty members. The easiest way to locate
a user is to send mail to OPERATOR@cc.usu.edu or, if your
system supports the bitnet SEND command, use SEND OPERATOR@USU
and ask them to look up the name for you.
Vanderbilt University:
Engineering faculty and grad students: @vuse.vanderbilt.edu
(most user IDs are the three initials)
Undergrads and other grad students: @ctrvax.vanderbilt.edu
Most user IDs are llllllfm (8 chars max). You can't finger
on this VAX cluster; try sending mail to
userserv@ctrvax.vanderbilt.edu; you should get a response
within a business day or so.
Vassar:
Students: FMLLLLLLLLLL@vaxsar.vassar.edu. (Every student is given
a VAX account, but few actually use them.)
Faculty: Faculty must request an account in order to get it,
but most of those who have accounts use them. Faculty
usernames are lastnames followed by enough letters of the
first name to ensure uniqueness. Their accounts are also on
vaxsar.vassar.edu. Fingering with the username or the lastname
will usually work.
Virginia Tech:
Computer Science students at Virginia Tech (aka VPI or VPI&SU for
Virginia Polytechnic Institute and State University, normally just
Virginia Tech, though) can be found at:
EE: vtccts1.cc.vt.edu, eddie.ee.vt.edu
CS: csugrad.cs.vt.edu
Undergraduates: userid@csugrad.cs.vt.edu
Graduate Students: userid@csgrad.cs.vt.edu
Faculty: userid@vtopus.cs.vt.edu
There is also the SSI Mail account. If a person has an SSI Mail
account it will be: firstInitialLastName@vtssi.vt.edu. It is common
for undergrad students (especially non-CS) to get an SSI Mail account
rather than a CSU account because it doesn't cost any money.
Wake Forest University:
llllllfm@wfunet.wfu.edu
Washington University, St. Louis MO:
Arts&Sciences undergrads: fmllllll@pear.wustl.edu
Undergrad Engineers: All have accounts on cec1.wustl.edu and
cec2.wustl.edu (cec2.uucp). Userids are the user's three initials
followed by a single digit for disambiguating name conflicts. If
there is no name conflict, the extra digit is a 1. Fingering from
outside the university sometimes works. Also, some computer science
students have accounts on wucs1, and anyone (including people
outside W.U.) can have an account on maria. On these machines, the
user chooses his/her own login name to be enabled. Usernames for
engineering faculty are just their three initials.
Other Undergrads: Try wugold.bitnet
Wayne State University, Detroit MI
All students in the University, regardless of their major or college
can have access to an account.
Engineering: ss0.eng.wayne.edu (or nova, or ece, or any solar planet,
e.g. sun, venus, ...)
CS: jupiter.cs.wayne.edu, zeus.cs.wayne.edu
These machines support finger. Most other students' accounts
are on wu.cc.wayne.edu; try 'finger partial-name@wu.cc.wayne.edu'
to find information about anyone with "partial-name" in their name.
Wellesley College (Wellesley, Massachusetts)
FLastname#@lucy.wellesley.edu, where F is first initial, and digit #
is used only to disambiguate (e.g. JSMITH1). Finger not accepted from
remote sites. Faculty names never get the #.
Wesleyan:
Accounts are on eagle.wesleyan.edu. The username is of the
form FLname, where F is the first initial and Lname is the
lastname of the individual.
West Chester University:
Users (at least undergraduates, if not others) are given
accounts on a machine whose name is the same as the first
letter of their last name. Usernames are of the form fllllll.
So John Doe would be jdoe%d%wcu@isn.wcupa.edu. Send mail
to postmaster@isn.wcupa.edu if you have questions.
West Point, the United States Military Academy
Host names are of the form usmaX.usma.edu, for X from 1 to 18.
Try 'finger lastname@host', starting with usma18 (since lower-numbered
machines tend to refuse a finger connection). Actual mailboxes for
cadets are of the form xYNNNNCC where x is the letter x, Y is last
digit of graduating year (e.g. 6 for 1996), NNNN is a student ID code,
and CC is company (letter-digit, e.g. D4).
Western Montana College
Try f_llllllll@wmc.edu. This site has no finger server.
Address: 710 S. Pacific, Dillon, MT 59725
Wheaton College:
UUCP: tellab5!wheaton!fmllllll
Widener University:
General: First.Last@cyber.widener.edu (it may also need a
middle initial)
CS: lastname@cs.widener.edu
Willamette University, Salem OR:
userid is <first initial><lastname> (e.g. ksmith)
up to 8 characters
all students, faculty and staff
<userid>@willamette.edu
Williams College:
williams.bitnet. Username is YYFML (YY = year, F = first
initial, M = middle initial, L = last initial). Some usernames
have a _C postpended (YYFML_C).
I believe this machine is vax.cc.williams.edu.
Williams' postmaster will not give out user ids to outside
requests.
Worcester Polytechnic Institute:
@wpi.wpi.edu
Yale:
Fingering name@directory.yale.edu will give you all Unix people's
email addresses, as well as their phone numbers. Finger
Finger@directory.yale.edu for further directions.
Grad CS, Undergrad CS: lastname-firstname@cs.yale.edu (yalecs.bitnet)
Undergrad Accounts (plus faculty & grad students in many non-CS
Graduate School depts.): LLLFFFM@yalevm.ycc.yale.edu (or
LLLFFFM@yalevm.bitnet). LLL is the first 3 letters of the last name,
FFF is the first 3 letters of the first name, and M is the middle
initial. Users can also request custom names. Mail queries can go to
consult@yalevm.bitnet or postmaster@cs.yale.edu, as appropriate. Some
non-CS undergrads can be reached at lastname@minerva.cs.yale.edu.
Medical School: yalemed.bitnet

Search for "Subject: [#]" to get to question number # quickly. Some news
readers can also take advantage of the message digest format used here.
If you know very little about data compression, read question 70 in
part 2 first.
------------------------------------------------------------------------------
Subject: [1] What are these newsgroups about?
comp.compression is the place to discuss about data compression, both
lossless (for text or data) and lossy (for images, sound, etc..).
comp.compression.research was created later to provide a forum for
current research on data compression and data compression algorithms.
If you are not experienced in data compression, please post in
comp.compression only.
If you only want to find a particular compression program for a
particular operating system, please read first this FAQ and the
article "How to find sources" which is regularly posted in
news.answers.
If you can't resist posting such a request, other groups are probably
more appropriate (comp.binaries.ibm.pc.wanted, comp.sources.wanted,
comp.sys.mac.wanted, alt.graphics.pixutils). Please post your request
in comp.compression only as a last resource.
Please do not post any program in binary form to comp.compression.
Very short sources can be posted, but long sources should be be posted
to the specialized source groups, such as comp.sources.* or alt.sources.
As for any newsgroups, do not post the same message separately to
comp.compression and comp.compression.research.
------------------------------------------------------------------------------
Subject: [2] What is this .xxx file type?
Where can I find the corresponding compression program?
All the programs mentioned in this section are lossless.
For most programs, one US and one European ftp site are given.
(wuarchive.wustl.edu: 128.152.135.4, garbo.uwasa.fi: 128.214.87.1)
Many other sites (in particular wsmr-simtel20.army.mil: 192.88.110.2)
have the same programs.
To keep this list to a reasonable size, many programs are not
mentioned here. Additional information can be found in the file
ux1.cso.uiuc.edu:/doc/pcnet/compression [128.174.5.59] maintained by
David Lemson (lemson@uiuc.edu). When several programs can handle
the same archive format, only one of them is given. Sources for
additional lossless data compressors can be found in
garbo.uwasa.fi:/pc/programming/lds_10.zip.
For Macintosh programs, look on sumex-aim.stanford.edu:/info-mac [36.44.0.6].
For VM/CMS, look on vmd.cso.uiuc.edu:/public.477 [128.174.5.98].
For Atari, look on terminator.cc.umich.edu:/atari/archivers [141.211.164.8]
For Amiga, look on ux1.cso.uiuc.edu:/pub/amiga [128.174.5.59]
If you don't know how to use ftp or don't have ftp access, read the
article "How to find sources" which is regularly posted in news.answers.
If you can't find a program given below, it is likely that a newer
version exists in the same directory. (Tell me <jloup@chorus.fr>)
A very short description of the compression algorithm is given for
most programs. For the meaning of LZ77, LZ78 and LZW, see question
70 in part 2 of the FAQ.)

Subject: [3] What is the latest PKZIP version?
The latest official version is still pkzip 1.10. An alpha version
1.93a has been released in Oct 91 but pkzip 2.x is not officially
released at the time of writing (Nov 27th 1992). From the PKWARE BBS
(June 92): "PKZIP 2.0 is expected to be released sometime in the next
few months, as soon as possible".
See item 2 above for ftp locations of pkzip 1.10 and 1.93a. There
have been several bogus versions uploaded to some BBS's. Some
information is included below.
