MercuryH, The PH lookup server

The MercuryH server allows remote systems to query information about users on your net-
work, using data you provide in the form of a Pegasus Mail addressbook. The query process
is largely automatic – all you need to do is create the data using any version of Pegasus Mail.

Configuration

Addressbook file Enter here the path to the Pegasus Mail addressbook file MercuryH should The addressbook should
use when resolving queries. Pegasus Mail addressbooks consists of two files with the same be created using Pegasus
Mail: the latest versions of
name, one with the extension .PMR, the other with the extension .PM!. MercuryH only needs Pegasus Mail are always
access to the .PMR file - enter the path to this file in this field. available from our home
web site,
http://www.pmail.com
MOTD file The PH protocol allows you to define an arbitrary text message (referred to as a
Message Of The Day, or MOTD file) that is sent in response to a PH status command. Enter
the name of the text file MercuryH should send when it receives a status command here. The
file should be plain text, with lines no more than 60-70 characters in length. This field is op-
tional – you do not have to provide a MOTD file. You can perform simple text editing on
your MOTD file by clicking the Edit button after you have entered the path.

Admin address The PH status and siteinfo commands can advertise the address of an admin-
istrator to whom requests for support should be sent. If you wish to have a PH server admin-
istrator, enter his or her full e-mail address in this field. As with the MOTD file field, this
field is optional.

TCP/IP Timeout The length of time in seconds that MercuryH should wait for data on a con-
nection before assuming that the connection is no longer valid and aborting it.

IP Interface to use If your computer supports multiple IP interfaces, you can use this field to
tell MercuryH which interface it should select when listening for connections: enter the in-
terface as a dotted IP address in the general form www.xxx.yyy.zzz. As an example, your
system may have one IP address assigned to a dialup PPP connection, and another, different
IP address assigned to a local Ethernet network - you would enter here the interface Mercu-
ryH should use. If you leave this field blank, MercuryH will listen on all available interfaces.
Unless you are very sure of what you are doing, or have been instructed by an ISP or network
administrator, you should leave this field blank. If you change the IP interface in this field,
you must restart Mercury before the new interface number will be used.

Listen on TCP/IP port By default, MercuryH listens for connections from the outside world
on port 105, which is the standard reserved port for the PH Query protocol. In some cases,
particularly when you are behind a firewall, you may wish to listen on an alternative port -
enter the number of that port in this field. If you change this field and save the dialog, you
will need to exit and restart Mercury/32 before the change will take effect.

Connection control and logging Please see the section above, Configuring the MercuryS
SMTP Server module, for information on controlling who can connect to your server, and on
generating logfiles.
