Command Line Clients

Stanford whois Client

Data stored in the LDAP directory can be retrieved using the whois protocol. The whois client is a standard utility installed on Linux and Macintosh systems. The Stanford whois service returns the following information:

  • Contact information for Stanford users marked "Public" in StanfordYou.
  • NetDB host information for campus hosts when the queries originate from campus hosts.

The Stanford developed whois client, swhois, is available on the Stanford time share systems. This client authenticates itself to the Stanford whois service using Kerberos and displays contact information that is marked "Stanford Only" in StanfordYou.

OpenLDAP Clients

Available on all Macintoshes running OS X and on many Linux systems is the ldapsearch command line client. The client supports direct searches of any LDAP standard server. The client supports authenticated Kerberos binds to the directory. An authenticated bind to the directory allows access to data marked as "Stanford Only" in StanfordYou.
