The INQUIR Database
INQUIR is the central CSAIL user account database. It is currently implemented as a PostgreSQL database though its history dates back through many incarnations to at least the days of ITS on DEC PDP-6 and PDP-10 systems.
It is used to map people to user-names, UIDs and groups as well as being authoritative for email forwarding and homepage URL so that http://www.csail.mit.edu/~YourUserName will be directed to the website of your choosing which could be a CSAIL hosted
personal page or any other website of your choosing.
You can view your inquir entry from a Unix system such as the CSAIL
login server by typing
whois -h inquir.csail.mit.edu <username> at the command prompt. You can also
finger <username>@csail.mit.edu
See
man 7 inquir on CSAIL Debian systems for additional info.
You can
update your INQUIR entry using several mechanisms.
