- What is the NRS?
- .LP
- The Name Registration Service (NRS) is operated by the University
- of Salford on behalf of the Joint Network Team (JNT) of the
- Computer Board.
- It maintains a database of information relating names of
- entities (machines) and services to X.25 addresses on both JANET and
- PSS and vice versa.
- .LP
- The NRS also provides a number of packages for accessing the database
- in various ways.
- These latter packages are written in FORTRAN.
- .SH
- What is the NRS database processor in C?
- .LP
- The NRS database processor in C is a configurable package to take
- the output of the NRS database, and convert it to forms suitable
- for input to a number of other programs, typically mail and
- communications systems.
- .SH
- What output formats are supported?
- .LP
- The package can produce output in the following forms:
- .IP \(bu
- Yorkbox directory tables.
- Both the current release (2.2) and the previous release (2.1) of the
- software are supported, although the tables are more compact and
- easier to inspect with release 2.2.
- .IP \(bu
- Mmdf channel and domain tables
- .IP \(bu
- X25hosts format.
- This is used for the UBC X.25 code.
- .IP \(bu
- Text format, similar to the t.central format produced by the NRS
- (useful for sticking on the wall as wallpaper!) as well PR1ME
- (also similar to t.central) and edtext which is actually quite useful.
- .IP \(bu
- VAX/VMS "Coloured Book".
- .IP \(bu
- Sendmail tables.
- Both the UK-1.4 sendmail configuration suite, and the Reading
- sendmail suite are supported.
- .IP \(bu
- DBM mode.
- This is a textual representation of the DBM format used by the UCL niftp
- suite. It is passed through dbencode to generate the DBM file.
- .SH
- What do I need to get it running?
- .LP
- The package is written in C and should be readily portable to most
- systems having a C compiler.
- However, it does require about 80kb of heap space (on a
- VAX) in addition to 70kb of program and static data.
- This size may be reduced by configuring out some of the output
- formats - full details in the kit.
- In addition, it must be possible to move to any point in a file
- without restriction.
- It is known to run on
- .UX
- systems of a number of flavours, on VAX/VMS V4 with the VAX/VMS C
- compiler version 2.1 and on PR1MEs.
- .LP
- Besides the aforementioned C compiler, the only other requirement
- is a copy of the current NRS database.
- This can be obtained by FTP from the NRS machine.
- However, this does necessitate a valid username & password for
- the NRS machine.
- All academic institutions have an NRS administrator (often in the
- Computer Centre), who can supply details of this on request.
- If in difficulty, try contacting the NRS direct.
- You can call uk.ac.nrs on X29 or TS29 (currently 000014901000 and
- 000014901000/X29.000014901000 respectively) or phone
- John Davidson <JOHND@uk.ac.salf.r-d> on 061-737 7010.

- Where do I get this wonderful package?
- .LP
- A shar format copy (which is about 150k bytes) of
- the package may be obtained by one of the following methods:
- .IP 1)
- By anonymous FTP as follows:
- .DS
- Machine: uk.ac.nott.cs (JANET 000021000018)
- Filename: <FTP>/nrs-shar
- Authorisation: guest
- Password: your-own-name
- .DE
- .IP 2)
- By mail from jpo@uk.ac.nott.cs, pb@uk.ac.cam.cl
- or from the UK distributed info-server.
- Send mail to info-server at uk.ac.cam.cl, uk.ac.nott.cs or uk.ac.ukc,
- with a body of the form
