December 28th Shutdown

December 28, 2009 by IRIS Staff

IMAP/mail, home/project, Windows services (AD/WINS/printing), LDAP/NIS/DNS, DHCP and most other IDSG and IMG services will be affected. We will try to keep some basic network services running (DHCP, DNS/NIS), possibly in a reduced capacity.

While EECS-Secure, EECS-Guest and EECS-Open wireless LANS will be out of service during this time, the EECS and AirBears wireless LANS will remain operational during the outage.

The reason for this extended downtime is multi fold. The first is to repair the UPS that failed a couple of weeks back. The repaired unit will be placed back on line and extensive testing must be done to ensure it’s operation before we can depend on the UPS again. The second is to move data around which will allow us to remove from service a piece of software used to manage storage. This software is no longer under development and we need to remove our dependency on it. Lastly, some routine maintenance will be done which can only be done when systems are down. These are the kind of things that can only be done between semesters and we ask for you understanding during this disruption in service.

While the stated outage is from 10:00AM to 9:00PM, it may not take that long. This is a worst case scenario. If possible, services will be brought up sooner than 9:00 PM.

No Network Access for Some Machines

February 27, 2009 by Lars Rohrbach

As a result of some work being completed on the DHCP server this morning, some properly-registered mobile devices were refused DHCP support, so they were not granted access to EECS networks. Staff are in process of fixing the problem.

AirBears usage is not affected.

IRIS wireless networks problem at BWRC

February 20, 2009 by Mark Kraitchman

The IRIS dhcp daemon was not responding to requests for EECS, EECS-Open and EECS-Secure network support at BWRC (the 128.32.63.128/25 network).

A script utilized to update dhcp support at BWRC for the EECS, EECS-Open and EECS-Secure networks contained a logic error which resulted in an attempted restart of the dhcpd daemon when the dhcpd configuration files contained an error. Both the configuration file and the script were corrected and the dhcp daemon was started to resume service.

AirBears support at BWRC was not affected by this outage.

IRIS wireless support in other buildings was not affected.

This incident was not related to some devices on the BWRC restricted network (128.32.63.0/26) having incorrect netmasks.

DHCP service unavailable

May 29, 2008 by IRIS Staff

Earlier today, around 6pm, the DHCP service ceased functioning, causing systems that obtain their IP addressing dynamically to be unable obtain an IP address to use when connecting to the network.

Most systems that use DHCP to obtain their IP address will be affected by this and will not be able to connect to the network after reboot or lengthy disconnection from the network.

Systems that use DHCP but have already obtained an address may be able to stay on the network during this service malfunction – this depends on how individual systems are configured. Systems that do not rely upon DHCP (statically configured hostnames/addresses) should be unaffected by this problem.

Staff are looking into the cause of this problem.
