For more information, see the section of the ITS website for IT staff.
Here are some of the groups you can join. If your group or community is not listed here and you would like it to be, please let us know about it so we can add it.
Frontline Notify (fln). FLN (Front Line Notify) is a vehicle for announcing changes to or problems with U-M's information technology (IT) environment to the people who are on the "front line," providing IT support and assistance to the members of the university community. It is a listserv list to which only members of the list can send messages; this was done as a defense against spam. To subscribe to FLN, send an email message to firstname.lastname@example.org with the word SUBSCRIBE in the subject line of your message. To unsubscribe from FLN, send an email message to email@example.com with the word UNSUBSCRIBE in the subject line of your message.
Win2000. A forum for U-M Windows administrators. All aspects of Windows administration are discussed, but the primary focus is on the Active Directory and Windows domain environments. Access to this list is restricted to U-M personnel with uniqname and password. See Joining the Win2000 list for details.
MacSIG. The Macintosh Special Interest Group (MacSIG) mail group is designed to help University of Michigan computer administrators and support personnel stay informed of the latest developments regarding Mac OS on campus. To join, leave, view archives or change your settings, see the MacSIG Listserv page.
www-sig. A discussion forum for web server administrators and web application developers. This is a joinable group in the MCommunity Directory.
unix.admins. A discussion forum for UNIX system administrators at U-M. This is a joinable group in the MCommunity Directory.
umich-postmasters. The directory group firstname.lastname@example.org was created by the U-M Postmaster group for the purpose of notification about U-M email issues or problems. It consists of groups of campus postmasters (the naming scheme being <department>-email@example.com). It is intended to serve as a contacts list with names and numbers. To have your unit's group of postmasters added to the group, contact firstname.lastname@example.org.
afs-wg. This directory group is for those who are interested in AFS clients and/or servers. If you'd like to be added to the group, contact one of the group owners. (Search the directory for the afs-wg group to see a list of the group's owners.)
The NTP (Network Time Protocol) server address for the University of Michigan is ntp.itd.umich.edu
There are two LDAP server addresses for the University of Michigan:
MCommunity Directory: ldap.umich.edu
U-M Online Directory: ldap.itd.umich.edu
The MCommunity Directory essentially replaced the U-M Online Directory in July 2011. The U-M Online Directory remains available via LDAP only for now to allow U-M departments time to migrate their applications and such to the new directory. For reference, see LDAP Access to the MCommunity Directory (R1463).
Send your request to email@example.com.
When you no longer need your keytab, please alert the keytabs group so the unneeded keytab can be expired.
Here are the names and port numbers to use for the U-M Kerberos servers provided and maintained by ITS:
kerberos-1.umich.edu Port: 88
kerberos-2.umich.edu Port: 88
kerberos-3.umich.edu Port: 88
Kerberos Admin Server:

Here are the names and IP addresses to use for the U-M AFS database servers provided and maintained by ITS:
AFS Database Servers:
The actual formatted data that would reside in the CellServDB file:
|>umich.edu||# University of Michigan - Campus|
AFSDB domain name service records are set up for the cell and can be used instead if you prefer.
For further assistance with configuration issues related to AFS, send email to firstname.lastname@example.org.
The DNS (Domain Name System) resolver addresses that should be configured in clients and servers on the University of Michigan campus are 184.108.40.206 and 220.127.116.11
(Note that these are NOT the same as the authoritative DNS servers—dns1.itd.umich.edu and dns2.itd.umich.edu—which are used for NS record domain delegations and should not be used as resolvers.)
For information about DNS, see Campus DNS and DHCP Services.
Names that End in umich.edu
Third-Party Top-Level Domains (names that do not end in umich.edu)
Faculty and staff who need to register third-party top-level domain names for University of Michigan can send a request to email@example.com. The ITS DNS Domain Name Registration group can register names in these domains and more: .org, .net, .com, .info, and .us. Note that there is a small per-year fee for such registration and that departmental approval is required. Payment must be made using a university account number (ShortCode).
DHCP (Dynamic Host Configuration Protocol) is a service that allows machines to get their IP addresses and other information assigned by the network rather than having this done manually by a person. Basically, it allows a network administrator to attach a computer to a U-M network and then have that computer figure out its own configuration for connecting to the Internet automatically. This DHCP service is available for any school or department network on campus. It is considered part of the campus computing infrastructure and is free of charge.
The ITS Service Center can answer your questions about system administration and configuration.
These services are available to members of the University of Michigan community only.
