Stanford University Terminal Interface Message Processor


SAIL has a  Terminal Interface  Message Processor (Terminal  IMP, or  TIP)
which provides hardwired or dialup terminal access to other ARPAnet  sites
without going through SU-AI.   It also provides access  to SU-AI when  the
direct dialup lines are  saturated.  Our TIP  is officially called  SU-TIP
and nicknamed (by popular vote) FELT-TIP.

To use the TIP you first need  to know the telephone number for modems  of
the same  speed  as your  terminal  (unless it  is  hardwired to  the  TIP
locally).  The  current  telephone numbers  available  to SAIL  users  are
listed below.

speed (baud)	telephone number	lines in hunt group
110-300		494-9024		4
150/1200	493-3280		1
150/1200	497-1112		2

NOTE:  Please don't give out these numbers to anyone else!  SAIL users can
read them in  this file.   Landlubbers (i.e.,  non-SAILers) interested  in
accessing other sites  via the SU-TIP  must be authorized  by Les  Earnest
(LES@SU-AI).  It's  in your  own best  interest not  to have  unauthorized
hackers (e.g., high school students using an MIT site) tying up TIP ports.
In addition, these telephone numbers will be changed every year or so, and
only the  authorized  non-SAIL TIP  users  will  be informed  of  the  new
numbers.  Remember, the TIP you save may be your own!

Once you've dialed  up the  TIP, you usually  need to  give the  following
commands to open a connection (i.e., TELNET) to SU-AI:

@R<cr>		[or just "E" on either a 110-300 baud or hardwired port]
@O 11<cr>

When a session  is done and  you have logged  out of SU-AI,  give the  TIP
command

@C<cr>

To get SAIL Datamedia display service  read the directions on "Use of  DMs
via TIPs"  in  DM.ME[UP,DOC](5).   In addition,  the  entire  TIP  command
language is documented in the "User's  Guide to the Terminal IMP" by  BBN,
which is found in TIPUG.BBN[UP,DOC].

Subject: TIP login

     At the November 1978 Sponsors' Group meeting ARPA and DCA
launched a project to implement "TIP login".  This means that a 
terminal user will have to identify himself to the TIP before 
any network connection can be opened.  It is being implemented to
control access to the network.

     Presently there is not enough core storage in the TIPs to 
implement the necessary code.  Also, we have recently received a 
number of complaints about insufficient buffer space in the TIPs
to handle new terminals being added.  We are therefore proposing
three changes which will free up needed core.

1.  Once again, we will deactivate "old Telnet".  We believe all
previously identified problems with new Telnet within the TIP
have been resolved.  Also, host servers have had over three 
years to implement new Telnet.

2.  We propose to abolish "remote controlled Telnet echoing"
(RCTE).  This is a set of negotiated Telnet options which 
provide a choice of echoing modes.  It has been on-line in various
stages of completion for three years but is not widely used.
Removal of RCTE would return the largest amount of storage of
the three changes, about 600 (decimal) words.  On the balance, 
the general welfare of the network will be better served by
replacing it with the TIP login code.

3.  Code to support the IBM 2741 will be removed from all TIPs.

     DCA requests comments on these proposals by 15 June, 1979.  
Please be sure you info your sponsoring agency.  Tentatively
1 December 1979 is proposed to remove the old code, with cutover
of TIP login in January 1980.

Brian,
Basically all hosts will be "forced" to change their code to accept
a coded password from a "network login server" as verification of a user.
The user will then only have to login once (to the "network
login server").

Hosts that are slow in changing their code to accept this will have to have
their users login twice. (once the the "network login server" and once to
the host itself (as usual).

Hope this is clear enough...
