Lines: 21 doesn't appear to accept interactive logins. We can
access the BITFTP at Princeton University from here and it gets into Umich
ok but if I do a direct FTP, it chucks me out.

Is it possible that Umich... has a list of servers that it will accept connects

Anyway, as an alternative, try:  This has a server which doesn't accept connects
                            from the U.S.A. (and who can blame it) but the
                            alternative in the You Ess of Ay is:    This is internationally accessable.

I suppose you all knew this but just in case, I thought I'd mention it.

This is like the servers for Simtel on BitNet.  It takes the same
commands like "HELP", "DIR", "/PDDIR", "/PDGET", etc.

U.S. people should be able to connect to via ftp. If you
can't problem may be with your ftp-program. Here is README file from
nic for more info:

		Internally also:  NIC.FUNET.FI

    This is a Sun4/330 with (9-Jun-91) 4.2GB archive disk space (3.3GB used).
This is owned by the  Finnish Academic and Research Network Project FUNET,
and is located at the Finnish State Computing Centre, near Helsinki, Finland.

	NOTE:	If you have troubles with multiple intermediate reply
		lines from FTP server, try prefixing your entry for
		`Password:' prompt with `-'.  If your REAL password
		in THIS system starts with `-', enter TWO `-' characters.


    - Intro
    - What is considered proper conduct of anonymous FTP usage
    - Non-standard FTP features
	( Dumping subdirectories, compressing files, uncompressing files..
	  when transfer in action! )
    - Physical disk structure is hidden behind logical one
    - Restrictions
    - Minimum of maximum retrieval rate
    - IP-reversal and valid "passwd" requirements
    - Contacts about material in here
	( GIFs and others )
    - Uploading
    - FTPD sources
    - What is `Freely distributable' ?
    - Other services available from here


    This system has plenty of freely distributable material on its FTPable
areas. We also have plans for a couple of info-server -like systems for
maildelivery of remote files (few which are monitored here).  BUT NOT YET!
(Details will be explained later when those systems are operational)

    If you have any questions regarding materials in this archive, read
first `Contacts about material in here' below.  If you can't locate correct
person/mail alias with it, try `'  for every moderator,
or as a final resort only  `'


    Like many systems world wide, ours offers  anonymous  logins for
FTP users.   For those who have this priviledge of using ftp, here are
some do's and don'ts:

	- When you are working over long distance links, do limit yourself
	  to off hours.  When working between the USA and Finland, try it
	  after 4 PM OUR time ( 10 AM Eastern USA time.)  And remember that
	  we wake up 10 hours before California.
	  We are at time zone  `GMT +2h'.

	- 90+% of material in this archive are originated from various
	  locations all over USA.  Sometimes those locations are well
	  known.  Often not.  We try to indicate origins if we know them.
	  DO try to use server nearest (network wise) to yourself, USA
	  folks: please restrain  yourself to USA.
	  Quite many central european sites have connections to RIPE/NORDUnet
	  only via USA,  thus USA located servers are nearest for them too.

	- When you log in anonymous, you are prompted with:
	    331 Guest login ok, send ident (your email address) as password.
	  It really means what is says: Give your email address as password.
	  We might spot problems on files and send warnings to those who
	  have requested that(/those) file(s).

	  If your FTP program uses  getpass(3) routine blindly (most
	  BSD networking source derived FTP programs), you can't enter
	  more than 8 characters for password.  Ever.
	  Try to install FTP program from pub/localsrc/reno+mea-ftp.tar.Z.
	  You can then feed in a lot longer `passwords'.
	  (It has replacement for getpass() which inputs 130 chars.)

	- When you upload something, make sure it is freely distributable.
	  For example some GIF images we have gotten are very obviously
	  scanned from magazines, which have publication copyrights on them.
	  This makes it illegal to copy those pictures `without the prior
	  written consent of the publisher.'

	- See below more about what is `Freely Distributable'.
	  After all, it is not always the same as Public Domain!



	This FTPSERVER has some special features which may help on grabbing
        files from here:

	<filename>.Z	Compress designated file while
			fetching from this system.
	<dirname>.tar	Make a TAR (using GNU tar-1.07) of dir.
	<filename>.tar	Make a TAR (- " -) of file.
	<dirname>.tar.Z Make a compressed tar of dir.
	<filename>.tar.Z Make a compressed tar of file.
                        (Why to tar a single file? To get its date & time
                         information too...)
	<filename>+".Z"	How to say...  There exists file:  <filename>.Z,
			you ask it to be UNCOMPRESSED for FTP transfer...
			(For all of you who can't uncompress a'la BSD UNIX.)

	Note:	It isn't very useful to compress .arc, .zoo, .gif or
		.Z files.  Usually they just expand when compressed :-(
		(Why?  They all use similar compression schemes.)

	Note2:  This ftp server won't perform .tar or .tar.Z transfer
                (mentioned above) for top level directories.
		This is to avoid accidental loading of whole archives over
		the network to your disk.   Several gigabytes of .tar isn't
		very easy to handle.
                So .tar and/or .tar.Z will only work in some subdirectories.
                Of course, this restriction doesn't apply for regular files.

	Note3:	Unless you REALLY can't uncompress files, please only then do
		retrieve files in their uncompressed form! (Leaving out the
		".Z" from true file path.)
		There are workable 16-bit UNcompress programs available for
		all machines which have at least 640k memory!

	Special command   `FIND regexpr'  (your average UNIX ftp client
accepts it like this:  `quote find gcc960')  to run regexpr matching against
files in archive.  It scans special file with ordinary egrep -program.

	If you have special FTP client, which sends PORT command before
sending FIND command, you can get search result into a file.
Exact features of this command will change, quite propably it will be
a frontend to ARCHIE some day.


	This server tries to hide physical disks and symlinks used to
point to them from the anonymous user, but occasionally you can trick
it to behave oddly.   For example under some conditions some multi-argument
ls command (NLST primitive) can create odd listings which are not of what
you might have expected.

We don't see any REAL need to hide physical structure completely, nor to
make even `ls' programs view of it bullet proof, but tell us your opinion.
( -> )

Most of the time  "cd .."  will move you one step up in your current
directory -- even when a component in it a symlink.

    The way this is implemented is described in  /staff-docs/ftpd-ls.README.


	This FTPSERVER counts the number of anonymous customers
simultaneously on the system, and currently limits it to 32 simultaneous
FOREIGN anonymous users (so it doesn't show how many finns there are, also
the restriction of 32 simultaneous users doesn't apply for the finns).

        Note that we are located far away from the USA. Our connection to the
USA is only a 256 kbits/sec terrestial link (which is used by all the scandi-
navian countries).   Our main purpose is to be central repository for finnish
users.  Lately traffic on that link has been TWICE as great TO the USA as it
has been to Finland, think about that...


	Due to above mentioned resource limits, this server implements
a throttle to limit individual users usage of scarse resource: line capacity.
Algorithm goes like follows:
	max_rate  =   Max_anonymous_logins * minimum_maximum_rate /
	max_rate 	is in (k)bytes/sec
	Max_anonymous_logins  is count shown at anonymous FTP login (32)
	minimum_maximum_rate  is rate  shown at anonymous FTP login (1kB/s)
			is a figure derived from ftp-server internal
			mechanism -- It tells (at sample time) how many
			are really transferring out of those who have
			logged in under your limited class.

If user can't use the share s/he has been allocated, nobody else will
get the leftovers (well, that line will be saturated anyway...)

This yields a rate which can be anything in between 1kB/s and 32kB/s.
(32kB/s is when you are only one transferring at the moment.)


	Any system without a valif IP reversal mapping will get a view of
directories which is even more restricted than the usual anonymous user.
The same is true when the email address you have entered as password does
not conform with RFC822 rules.

	If your IP address does not have IN-ADDR.ARPA. -reversing mapping
defined, this is a task for your network administrator.  Your NetAdmin must
register reversing database into  IN-ADDR.ARPA. -domain, and make sure all of
your local hosts have IP reversals defined!

	What we expect of IP reversals is valid top 2 domains:  -->
We are NOT interested in truly valid reversals, unless you want to
upload something!

This reversal is achieved with IP reversal entry in named.reverse:
	; all KNOWN 130.232.7.XX hosts here before "fallback"
	*.7	IN	PTR
Simple and effective!  Talk with your network management, they should
know what this is all about.  (If they don't, they can ask us.)

	Passwords for anonymous FTP are expected to be email addresses.  They
are expected to contain `@'-character in them, and be according to RFC822:
This address need NOT be on host you are using for FTP, but it must be valid
address to you in your preferred system.

	Valid email addresses are especially important if you want to upload
something.  On uploads email address validity is enforced by area moderators,
who may not want to make uploaded material public, if it isn't traceable.

NOTE:	If your IP-reversal fails, but you do have a host with globally
	accessible name->IP-address entry, and that host is in the same
	network as is the host you are using, then you can get past the
	restriction by using  as your password.
	Special case:	Use the name of your host itself, if it has a valid
			address entry.


	For interest areas:  There is a file  /etc/aliases  which
contains some comment informations from (fake) system mail alias database.
See if you can find proper contact  person/mail alias  from there.
There are aliases for at least following:

(This listing may be slightly out of sync with the reality at present..)


	386ix-adm	386 UNIX software (pub/unix/386ix)
	amiga-adm	CBM Amiga programs (pub/amiga)

	maints		All archive maintainers
	ftp-bugs	FTP server software bug reporting address
	managers	Everything archive related, which isn't proper
			for all the 100+ users.

	If you can logon (anonymously) and read this file, you propably
	do not have problems with your/our ftp software, therefore you
	should contact above mentioned area administrators.

	If you don't find suitable alias to approach, try:

	We also have a mail server for - among other things - to manipulate
internal mailing lists.  You may wish to join to  NEWMSDOS list for example:

		Subject: Requesting lists and help

		subscribe newmsdos Joe User

These will  1) add you to list NEWMSDOS with real name 'Joe User', 2) give
a list of locally known mailing lists, 3) print basic help with pointers
for more.  On overall, this behaves much in style of BITNET LISTSERVs, but
as it isn't LISTSERV, it isn't called one either.


	See file  /README.UPLOADER  for detailed procedure and explanations.
For short:  there are directories that are world writable, but do not let
uploaded files to be visible before maintainers check and approve them.

	What we expect uploader to do when uploading anything is stated in

	You may log into the system without being limited by the foreign
user count, if you use account  "uploader" instead of "anonymous".
Rules are still the same regarding the password.


	If you want the sources for this FTP server (derived from the
Berkeley freely distributable sources) look into /pub/localsrc for ls
and ftpd programs (GNU-tar and BSD-compress are unmodified).


	Freely distributable does not mean the same thing as PD
(public domain).  A big portion of the software available here is not
in the public domain, although it is freely distributable.  Many are
copyrighted by some person or organization, but can be distributed
freely; there may be limitations on the manner of distribution and/or
the usage of the programs.  There may also be certain rules concerning
the distribution of modified versions (derivate work) of the programs,
like saying that if you redistribute a modified version you must
include in the distribution the date and author of the modification.
Also on many programs you must include a note crediting the original
author of the program if you use his code in your own programs.

	An example of this is the Free Software Foundation's GNU
software.  GNU software may be distributed freely, provided that the
sources are included, an offer to distribute the sources is included
or that a pointer to where the sources can be gotten from is included.
On  NIC.FUNET.FI,  all the GNU source code published is available from
the directory  pub/gnu.   Some GNU binaries are available from other
directories as well; although we have tried to include a pointer to
the sources and the copyright information in these other directories,
too, it might be that we have neglected some.  This note is here to
point you to the sources in  pub/gnu.   For further information, the
GNU copyright is in the file  pub/gnu/COPYING.
