IRIS has offered a jabber/XMPP server for a number of years, but usage has dropped to zero as people have migrated to other options. When the current SSL certificate expires March 27, 2020, we do not plan to renew it, and this service will be retired.
As a replacement for this service, we recommend Google Hangouts Chat or Hangouts Meets.

Subject: Retirement of IRIS NIS service in EECS
IRIS NIS (Network Information Services) allows Unix computers to look up IRIS usernames, groups, passwords and other information from IRIS NIS servers.
Dating back to before the creation of IRIS, NIS service has been supported in the EECS Department. Now, IRIS provides the LDAP protocol as a replacement for NIS. This is now our supported service for distributing Unix username, password and group data. IRIS LDAP service features multiple redundant servers, and is updated in real-time with user account data.
