IHSUNRISE-2, Internet Help Memo for SUNRISE                            Page 1
 
This memo tells you how to use the Internet from SUNRISE, Syracuse University
Academic Computing  Center's VAX/VMS system.    The Internet is  a world-wide
cooperative network that includes NYSERNet, NSFnet,  and other networks.   It
also includes the  Syracuse University Internet which  interconnects SUNRISE,
RODAN, and SUVM as well as numerous other computers on campus including those
of   the   CASE   Center   and   NPAC.     SUNRISE's   "Internet"   name   is
sunrise.acs.syr.edu.
 
Using SUNRISE's Internet capabilities,  you can exchange electronic mail with
other Internet computers,  transfer files  between SUNRISE and other Internet
computers and can sign-on to and use other Internet computers interactively.
 
 
Mail
 
You can  send and  receive Internet mail  using normal  VMS mail  on SUNRISE.
Received mail  is delivered just  like any other  mail on SUNRISE.    To send
mail, you need to know the address of the recipient (the "Internet Address").
It will be of a form like:
 
                  hubbard@xanadu.sequoia.edu
 
                  edith@bigcorp.com
 
Start VMS mail as usual:
 
$ mail
 
When you  type SEND and  are prompted by  To:,  put double-quotes  around the
Internet Address and prepend it with the string internet% as follows:
 
To:      internet%"hubbard@xanadu.sequoia.edu"
 
To  send to  computers within  Syracuse University  such as  RODAN,  you  can
abbreviate  the Internet  name  by leaving  off  everything  after the  first
period.  For example, either of the following will send mail to username jdoe
on RODAN:
 
To:      internet%"jdoe@rodan.acs.syr.edu"
 
To:      internet%"jdoe@rodan"
 
If there is a  problem with the address or with  the receiving computer,  you
will be notified by a mail message.
 
 
Transferring Files
 
You can  transfer files between SUNRISE  and other computers on  the Internet
when you are  logged on to SUNRISE.   To  transfer files to or  from a remote
computer,  you need to know its Internet  name and an account and password on
it.
 
While logged on to SUNRISE,  use the FTP  command with the name of the remote
computer:
 
$ ftp xanadu.sequoia.edu
 
 
JMW 4/90
IHSUNRISE-2, Internet Help Memo for SUNRISE                            Page 2
 
The FTP  program will take a  little while to  lookup the name of  the remote
computer (e.g.  xanadu.sequoia.edu)  and will  establish a connection between
computers.   Then FTP will give you its  "usual prompt" which consists of the
Internet name of the remote computer followed by a greater-than sign (>):
 
XANADU.SEQUOIA.EDU>
 
Next, type login followed by your username on the remote computer.   FTP will
prompt you for a password.   When you  are successfully logged in,  you'll be
prompted for another FTP command.
 
XANADU.SEQUOIA.EDU> login planck
<Password required for planck.
Password:
<User planck logged in.
XANADU.SEQUOIA.EDU>
 
The password will not display on the screen when you type it.   The following
FTP commands will help you to transfer files:
 
dir - prints a directory of the files  on the remote computer.   It takes the
  name of  a directory (in  the syntax of the  remote computer)  as  its sole
  argument.
 
get -  copies a  file from  the remote  computer to  SUNRISE.   It  takes two
  arguments.   The first is  a file specification for the remote  file in the
  syntax of the remote computer,  the second  is a file specification for the
  local file to be created in the syntax used by SUNRISE (VAX/VMS).
 
put - copies a file from SUNRISE to  the remote computer.   It also takes two
  arguments.   The first  is a file specification  for the local file  in the
  syntax used by SUNRISE (VAX/VMS) and the second is a file specification for
  the remote file to be created in the syntax of the remote computer.
 
cd -  changes the working  directory on the  remote computer.   It  takes one
  argument which is the specification of a directory on the remote computer.
 
help - display a description of an ftp command.  With no argument, it gives a
  brief information  message.   If you specify  the name of a  particular FTP
  command as an argument, it will tell you about that command.  To get a list
  of commands, type help ?.
 
hash -  causes a  hash mark  (#)  to  be printed  after each  1024 bytes  are
  transferred.  This lets you know how the file transfer is progressing which
  is helpful when you are doing a long or a slow transfer.
 
binary - sets "binary mode", i.e., causes all subsequent "puts" and "gets" to
  transfer  files  without  translating each  byte.    Normally,   bytes  are
  translated so that text in the file remains readable.
 
ascii - sets "ascii mode" (the default),   i.e.,  nullifies the effect of the
  "binary" command.
 
quit - exits from FTP.

Using a Remote Computer Interactively
 
While logged  in to  SUNRISE,  you can  use other  computers on  the Internet
interactively.  To do so, you need to know the other computer's Internet name
as well as an account and password on it.
 
While logged  in to  SUNRISE,  use the  TELNET command with  the name  of the
remote computer:
 
$ telnet xanadu.sequoia.edu
 
The TELNET program will take a little while  to lookup the name of the remote
computer (e.g.  xanadu.sequoia.edu)  and will  establish a connection between
the computers.   Then  the remote computer will give you  its normal greeting
and sign-on prompt.
 
While TELNET maintains the connection with  the remote computer,  it supports
an "escape" character  which you can use  to direct the TELNET  program to do
several  different  things  without  necessarily  breaking  your  connection:
control-right-square-bracket  (press   the  right-square-bracket   key  while
holding down the control key).   A question mark (?) after this key will tell
you  what  TELNET can  do  for  you at  this  point.    One operation  is  to
immediately stop the session and return to SUNRISE.
 
The  other way  to end  your TELNET  session  is to  sign off  of the  remote
computer normally.

Problems
 
With TELNET and FTP,   there is always a pause after the  command is typed as
the program  looks up  the name of  the remote  computer you  are contacting.
There are a  lot of names,  so this  search can take seconds.    A message is
displayed,  then  it takes some  time to  establish initial contact  with the
remote  computer.   Thus,   you  must wait  a  little  while before  assuming
something has gone wrong.    The length of the wait depends  upon the load on
SUNRISE and the load on the network.
 
If you have reached a site at one time,  but cannot reach it at a later time,
the problem may well be simply network  load.   If the network is loaded down
too much, FTP or TELNET will refuse to connect you.
 
 
Reaching SUNRISE with Another Computer's FTP
 
When you use  FTP from another computer  to reach SUNRISE,  by  default,  you
reach the  directory associated with  your baseline project.    By specifying
other  directories and/or  devices,  you  may  "get" any  file your  baseline
project is allowed to read and may "put"  a file into any directory that your
baseline project is allowed to create a file in,  according to the protection
rules and quotas enforced by VAX/VMS.
