Ph servers
The Ph system allows you to look up directory information, usually including e-mail addresses at universities, research institutions, and some governmental agencies throughout the world.
You need a program (a "client") that lets you use Ph. Tell your Ph client which Ph server to use, and then enter a name you would like to search for. I usually try last name first, but first name first may work as well. You can try just last name, but that may yield too many results, in which case try last name plus first initial, etc.
For Ph users:
- Ph searching via the Web
- NWU's Ph site has good info for users and administrators
- Ph clients for your Mac, PC, or other
- Q: How to change your Ph data? A: contact your local computer administrator to find out how. MacPh lets you change your Ph data if your Ph server allows this; I don't know if any of the Windows Ph clients have this feature. (or ask your admin to install software to allow changes via the web)
- Servers maintaining a list of known Ph servers
- To distribute the load better, more servers ought to be carrying the list of known Ph servers. If you use Eudora 3.0 or above, see the instructions below for how to download a list of known servers. If your server does not carry a list of known servers, or it is not up-to-date (compare with the list in the link below), encourage your computing department to see the section below for Ph administrators; it includes brief information on how to include the list of known servers, and how to get more detailed help.
- list of known Ph servers. If your organization or business is not listed:
- You may still have a Ph server available. Check with your computing department.
- If there is one available, ask them for the server address, and whether you can send it to be added to the list
- If there is not one available, refer them to this page if you wish to suggest to them that they add a Ph server.

For Ph administrators (or those wishing to set up a Ph server at their site)
- See University of Illinois publication about Ph
- Ph FAQ
- NWU's Ph site has good info for users and administrators
- For Ph administrators or those that wish to run a Ph server at their site: Click here
- Contact me to add, change, or delete your listing on the list of known Ph servers. If you want your site to be a mirror of this list of known Ph servers (and we strongly encourage you to do so to help distribute the load!):
- There's a Perl script in the standard qi/ph distribution package from UIUC that you can run in a cron job to periodically update your site list records from our master list at Northwestern University. See the file: qi-3.1B7/xtra/getservers.pl (Let me know if you become a mirror.)
- If you have difficulty using the above, you might try the Ph mailing list (see FAQ) or Ph FAQ.
- Ph Servers and related utilities
- Note: Ph servers are generally known as "Qi" servers.
Ph clients for your Mac, PC, and other machines
Macintosh:
- Eudora.
- Ph for Macintosh by John Norstad.
- Ph Client for OS X by Sleep Spent Software
- QuickMail Pro by CE Software.
- Internet Lookup by Dartmouth does Ph, Finger, and Whois, as well as DND, a system Dartmouth uses. See the DND page for more information.
- Notes
- If you use Internet Config, you can set Ph or Eudora to handle URLs of the form ph://qi.cornell.edu or ph://qi.cornell.edu/Zimmerman%20Hank (substituting appropriate server and name). Note that %20 should be used in URLs instead of spaces.
- If you tell Ph to default to one of the servers that maintains a complete list of Ph servers, you can then scroll through the list nicely within Ph to choose which one to query.
Windows:
Other:
- JavaPH is a client used for querying PH servers - distributed as a free, open source, cross platform, lightweight, app/applet. Future development tasks are to add ability to save XML, query multiple servers and collate results, and create documentation."
- Northwestern University's Ph client for unix
- Ph for a variety of platforms, including Unix and Vax/VMS

There may be more; if you find any others that return approximately 325 entries, please let me know. Also, encourage your computer administrator to have their Ph server mirror the Northwestern server. Refer them to the administrator section at the top of this page for more information on how to do this.
