Ladies & gentlemen,
a little announcement:

After looking at Graham Barr's (Graham_Barr@tiuk.ti.com)code in 
Net::Cmd and Net::FTP, I decided to extend the Net library with 
Net::Ph.

For almost a year I was writing simple cgi scripts in perl to deal
with the CCSO Nameserver (aka PH) developed by the University of
Illinois at Urbana-Champaigne. The CCSO Nameserver is a database
containing info about people in an organization. It consists of a 
"qi" server and a "ph" client; the latter available for variety 
of platforms (UNIX, DOS, Win, Mac, VMS). Even, the Qualcomm Eudora 
mail application comes with an integrated ph client.

This client/server environment serves as a centralized database for
Schlumberger Ltd.(the company I'm working for). Simply stated, it
is a phone directory.

The server implementation is quite similar to an ftp daemon: it uses
a command-reply scheme. Commands consist of keywords followed by
one or more arguments; replies consist of numerical codes (-599 to
599) and additional text.

List of commands:
=================
query   [field=]value... [return field...]
change  [field=]value... make field=value...
login   alias
answer  code
clear   password
logout
fields  [field...]
set     option[=value]... *
id      information *
add     field=value...
delete  [feild=]value...
status *
siteinfo *
help    [{native|client} [topic...]] *
quit

*not considered in Net::Ph for now

List of reply categories:
=========================
100-199  operation in progress 
200-299  success
300-399  a request for further information
400-499  temporary failure
500-599  permanent failure
-599 to -100 more replies to be expected for the current command;
             have the same meaning as their positive counterparts


Here is a brief description of Net::Ph.
===========
constructor
   new (HOST [,OPTIONS])
   example: $ph = Net::Ph->new("host.name", Port=>105, Timeout=>20);

methods
   open_query (FIELDS,RETURN_FIELDS [, USER, PASS, ENCRYPTED])
   example: $qh= $ph->open_query(-fields=>{'field1'=>'value1',
                                           'field2'=>'value2'},
                                 -return_fields=>['value1','value2'],
                                 -user=>'username',
                                 -pass=>'password',
                                 -encrypted=>1);

   read_query (QH [, POS])
   example: 
      $pos = 1;
      while ( (($status,$buf)  = $ph->read_query($qh,$pos)) ) {
          foreach $field (sort keys %$buf) {
             print "$field = $buf->{$field}\n";
          }
          $pos++;
      }


   close_query (QH)
   example: close_query($qh);

   add (FIELDS [, USER, PASS, ENCRYPTED])
   example:
      ($status,$qh) = $ph->add(-fields=>{'field1'=>'value1'},
                               -user=>'username',
                               -pass=>'password',
                               -encrypted=>1);
       close_query($qh);

   delete (FIELDS [, USER, PASS, ENCRYPTED])
   example:
       ($status,$qh) = $ph->delete(-fields=>['value1','value2']);
       close_query($qh);

   change (SEARCH_FIELDS, CHANGE_FIELDS [, USER, PASS, ENCRYPTED])
   example:
       ($status, $qh) = $ph->change(-search_fields=>['value1'],
                           -change_fields=>{'field2'=>'value2'},
                                    -user=>'username',
                                    -pass=>'password');
        close_query($qh);

   quit
   example: $ph->quit();
========================

Feel free to look at the code and the manual page available at:
http://www.omnes.net/~alex/net_ph/

No installation script is avalable yet. I just keep Ph.pm in 
..../site_perl/Net

Any suggestions are more than welcome and appreciated.
