                           NAME/FINGER




Introduction

This note describes the Name/Finger protocol.  This is a simple
protocol which provides an interface to the Name and Finger programs
at several network sites.  These programs return a friendly,
human-oriented status report on either the system at the moment or a
particular person in depth.  Currently only the SAIL (SU-AI), SRI
(SRI-(KA/KL)), and ITS (MIT-(AI/ML/MC/DMS)) sites support this
protocol, but there are other systems with similar programs that
could easily be made servers; there is no required format and the
protocol consists mostly of specifying a single "command line".

To use via the network:

ICP to socket 117 (octal, 79. decimal) and establish two 8-bit
connections.

Send a single "command line", ending with <CRLF>.

Receive information which will vary depending on the above line and
the particular system.  The server closes its connections as soon as
this output is finished.

The command line:

Systems may differ in their interpretations of this line.  However,
the basic scheme is straightforward:  if the line is null (i.e. just
a <CRLF> is sent) then the server should return a "default" report
which lists all people using the system at that moment.  If on the
other hand a user name is specified (e.g. FOO<CRLF>) then the
response should concern only that particular user, whether logged in
or not.

Both ITS and SAIL sites allow several names to be included on the
line, separated by commas; but the syntax for some servers can be
slightly more elaborate.  For example, if "/W" (called the "Whois
switch") also appears on the line given to an ITS server, much fuller
descriptions are returned.  The complete documentation may be found
at any time in the files ".INFO.;NAME ORDER" on MIT-AI,
"FINGER.LES[UP,DOC]" on SU-AI, and "<DOCUMENTATION>FINGER.DOC" on





                                                             [Page 1]�

Name/Finger



SRI-KL, all freely accessible by FTP (with the exception of SRI-KL,
where TOPS-20 requires the "anonymous" login convention).

Allowable "names" in the command line should of course include "user
names" or "login names" as defined by the system, but it is also
reasonable to understand last names or even full names as well.  If a
name is ambiguous, all possible derivations should be returned in
some fashion; SAIL will simply list the possible names and no more,
whereas an ITS server will furnish the full standard information for
each possibility.

Response to null command line - "default" listing:

This is a request for a list of all online users, much like a TOPS-10
or TENEX "systat".  To fulfill the basic intent of the Name/Finger
programs, the returned list should include at least the full names of
each user and the physical locations of their terminals insofar as
they can be determined.  Including the job name and idle time (number
of minutes since last typein, or since last job activity) is also
reasonable and useful.  The appendix has examples which demonstrate
how this information can be formatted.

Response to non-null command line - "name" listing:

For in-depth status of a specified user, there are two main cases.
If the user is logged in, a line or two is returned in the same
format as that for the "default" listing, but showing only that user.
If not logged in, things become more interesting.  Furnishing the
full name and time of last logout is the expected thing to do, but
there is also a "plan" feature, wherein a user may leave a short
message that will be included in the response to such requests.  This
is easily implemented by (for example) having the program look for a
specially named text file on the user's directory or some common
area.  See the examples for typical "plans".

Implementation miscellany:

Anyone wishing to implement such a server is encouraged to get in
touch with the maintainers of NAME by sending a message to BUG-NAME @
MIT-AI;  apart from offering advice and help, a list of all sites
with such servers is kept there.  It is also suggested that any
existing programs performing similar functions locally (i.e. not as
net servers) be extended to allow specification of other sites, or
names at other sites.  For example, on ITS systems one can say
":NAME<cr>" for a local default listing, or ":NAME @SAIL<cr>" for
SAIL's default listing, or ":NAME Foo@MC<cr>" to ask MIT-MC about
Foo's status, etc.





                                                             [Page 2]�

Name/Finger



It should be noted that connecting directly to the server from a TIP
or an equally narrow-minded TELNET-protocol user program can result
in meaningless attempts at option negotiation being sent to the
server, which will foul up the command line interpretation unless the
server knows enough to filter out IAC's and perhaps even respond
negatively (IAC WON'T) to all option commands received.  This is a
convenience but is not at all required, since normally the user side
is just an extended NAME/FINGER type program.

And finally a little background:

The FINGER program at SAIL, written by Les Earnest, was the
inspiration for the NAME program on ITS.  Earl Killian at MIT and
Brian Harvey at SAIL were jointly responsible for implementing the
protocol just described, and Greg Hinchliffe has recently brought up
a similar server for SRI-KA and SRI-KL.

                             EXAMPLES



'''Note:''' it is possible for some lines of the actual output to exceed 80
chars in length.  The handling of such lines is of course dependant on
the particular user program; in these examples, lines have been
truncated to 72 chars for greater clarity.

             Three examples with a null command line:
