This is the minimal set of things you need to build an Archie client
that takes advantage of the Prospero system. It is derived from the
4.2beta version of Prospero, currently available as the file prospero.tar.Z
on the host cs.washington.edu.
* To make the client under Unix:
* edit the Makefile, changing CC, OPTIONS, LDFLAGS, and RM if
necessary (odds are you won't have to do this..see below)
* edit the DEFINEs as necessary
* if archie.ans.net isn't "close" to you netwise, please edit
ARCHIE in the Makefile appropriately. This is particularly important
if you're not in the US. You don't need to touch archie.h anymore.
* type `make'
I've tried to make this as portable as possible. I'd encourage you
to try doing a "make" without any changes to the Makefile, and see how
it goes. If it pukes, and you have to define something, please drop
me a line---my goal is for anybody to just type "make" and not have to
worry about things like what functions their system supports.
* To make the client under VMS, just type @MAKE and it'll ask you
which of the available Archie servers is closest. That's it!
* To make the client under MSDOS or OS/2:
* with FTP Software's PC/TCP for MSDOS (version 2.1 or higher) and
OS/2 (version 1.1 and higher), use makefile.os2 or makefile.dos
* with CUTCP (NCSA telnet), use makefile.cut

Archie in this manner.

Enclosed you'll find a Prospero client for the archie service. It'll
let you query the archie databases without actually using an
interactive process on the remote server's machine (e.g., archie.ans.net),
resulting in a MUCH better response time. It also helps lessen the
load on the archie server itself.
What's Archie? It's a system that will let you check a database containing
thousands of entries for the files that're available at FTP sites around
the world.
This is a third child of Clifford Neuman's Prospero project. It's really
the Archie client that's included in the prospero stuff, but I've taken out
everything that's unnecessary for this client to work. (Aka, you don't
have to build all of Prospero to get the Archie client.) Khun Yee Fung
wrote an archie client in Perl, George Ferguson has written a client
for use with XWindows, based in part upon this code. Also, Scott
Stark wrote a NeXT-Step client for the NeXT.
Using the Archie Prospero interface in its true form will probably be of
interest---check out the file `Prospero' for an example of its interface.
If you find it intriguing, you should probably get the full prospero kit
from the University of Washington on cs.washington.edu in pub/prospero.tar.Z.
Suffice to say, there are now a number of ways to query Archie without
bogging a server down with your logins.
Check out the man page (or archie.doc, if you're using VMS or DOS)
for instructions on how to use this archie client. VMS users please
note that you have to put quotes around args that are capital letters;
for example, $ ARCHIE "-L" to list the available servers.
Please check to make sure you don't have "archie" aliased or modified
in some way to do a telnet or rlogin (which you may've done before
this command-line ability came into being).
If Archie consistently hangs (at different times of day with
different queries), it's possible that your site has UDP traffic on
ports > 1000 blocked, for security reasons. Type `make udptest' to
check---if it prints out the date, the Archie server is probably down;
if it doesn't print out the date, either Widener's computer is down
(God forbid ;-) ) or you do indeed have UDP blocked. See your system
administrator in this case. If the problem persists and haven't the
vaguest, then write me describing the situation and what machine/OS
you're using.
Write to archie-group@cs.mcgill.ca with questions about Archie itself.
Write to info-prospero@isi.edu about the Prospero protocol.
Write to brendan@cs.widener.edu with questions about this specific package.

11/22/91 Readme.dos -- Readme file for CUTCP DOS version of Archie.
--
This version requires the use of a `standard' NCSA or CUTCP compatible
CONFIG.TEL file. If you are running NCSA telnet or CUTCP/CUTE telnet,
you should be able to run this program without modification.
As with all CUTCP programs, you may set a DOS environment variable to
point to the location of your config.tel file.
set CONFIGTEL=C:\net\config.tel
You may also set the $CUTCPnn dos environment variables to include other
'local' information (such as client IP address on a Novell lan).
This version has been compiled with the US (archie.sura.net) Prospero/Archie
server as the default. This may not be appropriate for your location. Here's
how to change it.
1. Run the archie program with the -L argument to list known
archie/prospero servers.
2. Select the server name that is closest to your site. For this example
we'll pick archie.funet.fi
3. Edit your config.tel file and add the following lines at the end
of the file.
name=archie
host=archie.funet.fi # actually substitute your select
# server name here
4. If you happen to know the IP address of the server, you may also
add the appropriate
hostip=<insert IP address here>
5. If you don't enter an IP address, archie will perform a DNS lookup
use the domain nameserver information that is in your config.tel
file.
An additional command line option (-H) has been added (vs -h) to allow the
user to specify the config.tel file location on the command line.
archie -H c:\net\config.tel emacs
During a search, you may press the <ESCAPE> key to abort the query.
If you have problems, try running archie with the -D9 option (debug).

Sample Config.tel file
------------------------------
# Example host file for ARCHIE/ CUTCP version
# 11/21/91
#
# Bugs to cutcp-bugs@omnigate.clarkson.edu
#---------------------------------------------------------------------------#
# #
#** ATTENTION ATTENTION ATTENTION ATTENTION ATTENTION ATTENTION ATTENTION **#
# #
# This sample config.tel file contains every single option that you could #
# possibly use. Its meant as an example only. Please Please PLEASE don't #
# use all these options in your working config.tel file, just the ones #
# that you actually need. Many options can be left out, the default action#
# (if defined) is shown in parens () next to the option. #
# #
# Thank you for your support #
#---------------------------------------------------------------------------#
#
# This example file is for my=bootp, in which case the following items are
# determined from the bootp server: (and are thus commented out in this file)
# 1. This machine's IP Address
# 2. The network NETMASK
# 3. The default gateway (one or more)
# 4. Nameservers (one or more)
# 5. The domain search list (if this clients hostname is in the bootp packet)
#
# Your BOOTP server needs to be RFC 1048 compliant for this to work
#
# If you have nameservers, gateways or a domainslist already specified
# in this file, then the file's entry takes precedence.
# Extra gateways and nameservers will be added by BOOTP if found, however.
#----------------------------------------------------------------------------
# You can set a DOS environment variable CONFIGTEL to point to this file
# then you don't need batch files or the -h option.
#
# C> set CONFIGTEL=C:\net\myconfig.tel
#
# You may also use environment variables to include config.tel options,
# such as:
# C> set $CUTCP1=myip~197.001.42.98;netmask~255.255.252.0
# C> set $CUTCP2=name~x;hostip~128.163.298.2
#
# and so on up to $CUTCP99. Note that you use a tilde (~) instead of (=)
# in the dos set command because two ='s are not allowed by Dos.
#
# Additionally, there is a new config.tel option called include= which
# allows the nesting (up to 3) configuration files deep.
#
#
# You can use these new options on networks to make your configuration job
# easier. CUTCP always opens config.tel files as read-only, so you can mark
# your files as sharable, read only. Also, you can use the include= command
# in a $CUTCP environment variable, and on the command line.
# *Note* that you can not include a machine specific parameter before
# name=default... This used to work in old versions, but is strictly
# enforced in this version.

# packet driver found between 60H and 7FH
noarpme=yes # Don't arp for myself before running? (no)
# if yes, inhibits the initial arp request
# for this IP address. However, if yes, won't
# warn you if another user is using this IP
# address. For some token ring systems, you'll
# need noarpme=yes.
include="nul" # if you want to include another file as part

# otherwise, don't use this option
domaintime=4 # domain name lookup timeout (first retry)
domainretry=4 # domain name max number of retries
domainslist="clarkson.edu,aux.clarkson.edu" # domain name search path
# domain name lookup will attach each of these
# comma seperated suffixes to
# the end of the name you are looking for to
# discover the full name and IP address.
# so, looking for x tries x.clarkson.edu and x.aux.clarkson.edu then just x
# unless you use x. which ONLY looks for x
## Also, the fewer suffixes in the domainslist
## the less time you will have to wait if you mis-type an entry.
## Finally, try not to use a suffix like . or .edu or .com this will
## waste a lot of time looking for a bogus host name if you mis-type an entry.

NAME
archie - query the Archie anonymous FTP databases using
Prospero
SYNOPSIS
archie [ -cers ] [ -l ] [ -t ] [ -m# ] [ -N# ] [ -h hostname ]
[ -L ] string
DESCRIPTION
archie queries an archie anonymous FTP database looking for
the specified string using the Prospero protocol. This
client is based on Prospero version Beta.4.2 and is provided
to encourage non-interactive use of the Archie servers (and
subsequently better performance on both sides). This man
page describes version 1.3 of the client.
The general method of use is of the form
% archie string
This will go to the archie server and ask it to look for all
known systems that have a file named `string' in their FTP
area. archie will wait, and print out any matches.
For example,
% archie emacs
will find all anonymous FTP sites in the archie database
that have files named emacs somewhere in their FTP area.
(This particular query would probably return a lot of direc-
tories.) If you want a list of every filename that contains
emacs anywhere in it, you'd use
% archie -c emacs
Regular expressions, such as
% archie -r '[xX][lL]isp'
may also be used for searches. (See the manual of a reason-
ably good editor, like GNU Emacs or vi, for more information
on using regular expressions.)
OPTIONS
The options currently available to this archie client are:
-c Search substrings paying attention to upper &
lower case.
-e Exact string match. (This is the default.)
-r Search using a regular expression.
Archie (Prospero) Last change: 9 January 1992 1
ARCHIE(1) USER COMMANDS ARCHIE(1)
-s Search substrings ignoring the case of the
letters.
-l Output results in a form suitable for parsing by
programs.
-t Sort the results inverted by date.
-m# Specifies the maximum number of hits (matches)
to return (default of 95).
-N# Sets the niceness of a query; by default, it's
set to 0. Without an argument, ``-N'' defaults
to 35765. If you use -N with an argument
between 0 and 35765, it'll adjust itself accord-
ingly. (Note: VMS users will have to put quotes
around this argument, and -L, like "-N45"; VMS
will otherwise convert it to lowercase.)
-h hostname Tells the client to query the Archie server
hostname.
-L Lists the Archie servers known to the program
when it was compiled, as well as the name of the
default Archie server. For an up-to-date list,
write to ``archie@archie.mcgill.ca'' (or any
Archie server) with the single command of
servers.
The three search-modifying arguments (``-c'', ``-r'', and
``-s'') are all mutually exclusive; only the last one
counts. If you specify -e with any of ``-c'', ``-r'', or
``-s'', the server will first check for an exact match, then
fall back to the case-sensitive, case-insensitive, or regu-
lar expression search. This is so if there are matches that
are particularly obvious, it will take a minimal amount of
time to satisfy your request.
If you list a single `-' by itself, any further arguments
will be taken as part of the search string. This is
intended to enable searching for strings that begin with a
`-'; for example:
% archie -s - -old
will search for all filenames that contain the string `-old'
in them.
RESPONSE
Archie servers are set up to respond to a number of requests
in a queued fashion. That is, smaller requests get served
much more quickly than do large requests. As a result, the
more often you query the Archie server, or the larger your
requests, the longer the queue will become, resulting in a
longer waiting period for everyone's requests. Please be
frugal when possible, for your benefit as well as for the
other users.

ARCHIE(1) USER COMMANDS ARCHIE(1)
QUERY PRIORITY
Please use the ``-N'' option whenever you don't demand
immediacy, or when you're requesting things that could gen-
erate large responses. Even when using the nice option, you
should still try to avoid big jobs during busy periods.
Here is a list of what we consider to be nice values that
accurately reflect the priority of a job to the server.
Normal 0
Nice 500
Nicer 1000
Very Nice 5000
Extremely Nice 10000
Nicest 32765
The last priority, Nicest, would be used when a job should
wait until the queue is essentially empty before running.
You should pick one of these values to use, possibly modify-
ing it slightly depending on where you think your priority
should land. For example, 32760 would mean wait until the
queue is empty, but jump ahead of other jobs that have
selected Nicest.
There are certain types of things that we suggest using
Nicest for, irregardless. In particular, any searches for
which you would have a hard time justifying the use of any-
thing but extra resources. (We all know what those searches
would be for.)
ENVIRONMENT
ARCHIE_HOST
This will change the host archie will consult when
making queries. (The default value is what's been
compiled in.) The ``-h'' option will override this.
If you're running VMS, create a symbol called
ARCHIE_HOST.

* get_vdir - Get contents of a directory given its location
*
* GET_VDIR takes a directory location, a list of desired

* directory server and retrieves the desired information.
*
* ARGS: dhost - Host on which directory resides
* dfile - Directory on that host
* components - The names from the directory we want
* dir - Structure to be filled in
* flags - Options. See FLAGS
* filters - filters to be applied to result
* acomp - Pointer to remaining components
*
* FLAGS: GVD_UNION - Do not expand union links
* GVD_EXPAND - Expand union links locally
* GVD_REMEXP - Request remote expansion (& local if refused)
* GVD_LREMEXP - Request remote expansion of local union links
* GVD_VERIFY - Only verify that args are for a directory
* GVD_ATTRIB - Request attributes from directory server
* GVD_NOSORT - Do not sort links when adding to directory
*
* RETURNS: PSUCCESS (0) or error code
* On some codes addition information in p_err_string
*
* NOTES: If acomp is non-null the string it points to might be modified
*
* If the directory passed as an argument already has
* links or union links, then those lists will be freed
* before the new contents are filled in.
*
* If a filter is passed to the procedure, and application of
* the filter results in additional union link, then those links
* will (or will not) be expanded as specified in the FLAGS field.
*
* If the list of components in NULL, or the null string, then
* get_vdir will return all links in the requested directory.

* Doesn't process errors returned from server
* Doesn't expand union links if requested to

* This removes the need to have seperate
* code in the pmatch case block - it is
* just CCL code now.
*
* Use the actual CCL code in the CLO
* section of pmatch. No need for a recursive
* pmatch call.
*
* Use a bitmap table to set char bits in an
* 8-bit chunk.
*
* Routines:
* re_comp: compile a regular expression into
* a NFA.
*
* char *re_comp(s)
* char *s;
*
* re_exec: execute the NFA to match a pattern.
*
* int re_exec(s)
* char *s;
*
* Regular Expressions:
*
* [1] char matches itself, unless it is a special
* character (metachar): . \ [ ] * + ^ $
*
* [2] . matches any character.
*
* [3] \ matches the character following it, except
* when followed by a left or right round bracket,
* a digit 1 to 9 or a left or right angle bracket.
* (see [7], [8] and [9])
* It is used as an escape character for all
* other meta-characters, and itself. When used
* in a set ([4]), it is treated as an ordinary
* character.
*
* [4] [set] matches one of the characters in the set.
* If the first character in the set is "^",
* it matches a character NOT in the set, i.e.
* complements the set. A shorthand S-E is
* used to specify a set of characters S upto
* E, inclusive. The special characters "]" and
* "-" have no special meaning if they appear
* as the first chars in the set.
* examples: match:
*
* [a-z] any lowercase alpha
*
* [^]-] any char except ] and -
*
* [^A-Z] any char except uppercase
* alpha
*
* [a-zA-Z] any alpha
*
* [5] * any regular expression form [1] to [4], followed by
* closure char (*) matches zero or more matches of
* that form.
*
* [6] + same as [5], except it matches one or more.
*
* [7] a regular expression in the form [1] to [10], enclosed
* as \(form\) matches what form matches. The enclosure
* creates a set of tags, used for [8] and for
* pattern substution. The tagged forms are numbered
* starting from 1.
*
* [8] a \ followed by a digit 1 to 9 matches whatever a
* previously tagged regular expression ([7]) matched.
*
* [9] \< a regular expression starting with a \< construct
* \> and/or ending with a \> construct, restricts the
* pattern matching to the beginning of a word, and/or
* the end of a word. A word is defined to be a character
* string beginning and/or ending with the characters
* A-Z a-z 0-9 and _. It must also be preceded and/or
* followed by any character outside those mentioned.
*
* [10] a composite regular expression xy where x and y
* are in the form [1] to [10] matches the longest
* match of x followed by a match for y.
*
* [11] ^ a regular expression starting with a ^ character
* $ and/or ending with a $ character, restricts the
* pattern matching to the beginning of the line,
* or the end of line. [anchors] Elsewhere in the
* pattern, ^ and $ are treated as ordinary characters.
*
*
* Acknowledgements:
*
* HCR's Hugh Redelmeier has been most helpful in various
* stages of development. He convinced me to include BOW
* and EOW constructs, originally invented by Rob Pike at
* the University of Toronto.

*
* Notes:
*
* This implementation uses a bit-set representation for character
* classes for speed and compactness. Each character is represented
* by one bit in a 128-bit block. Thus, CCL always takes a
* constant 16 bytes in the internal nfa, and re_exec does a single
* bit comparison to locate the character in the set.
*
* Examples:
*
* pattern: foo*.*
* compile: CHR f CHR o CLO CHR o END CLO ANY END END
* matches: fo foo fooo foobar fobar foxx ...
*
* pattern: fo[ob]a[rz]
* compile: CHR f CHR o CCL bitset CHR a CCL bitset END
* matches: fobar fooar fobaz fooaz
*
* pattern: foo\\+
* compile: CHR f CHR o CHR o CHR \ CLO CHR \ END END
* matches: foo\ foo\\ foo\\\ ...
*
* pattern: \(foo\)[1-3]\1 (same as foo[1-3]foo)
* compile: BOT 1 CHR f CHR o CHR o EOT 1 CCL bitset REF 1 END
* matches: foo1foo foo2foo foo3foo
*
* pattern: \(fo.*\)-\1
* compile: BOT 1 CHR f CHR o CLO ANY END EOT 1 CHR - REF 1 END
* matches: foo-foo fo-fo fob-fob foobar-foobar ...

* information associated with the new link matches that in

* link will only be added to the list of "replicas" if the
* allow_conflict flag has been set.
*
* If the link is not added, an error is returned and the link
* is freed. Ordering for the list of links is by the link name.
