- 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

- 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.

- 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.
