One of the two WINS servers is being upgraded today.
For a short period, we will be relying on one WINS server, WINS1.

BWRC wireless networking maintenance
There will be maintenance affecting BWRC
wireless networking starting Thursday
June 25, 2009 at 9:30 am. During the
maintenance, BWRC wireless clients will
not be able to get a new dhcp lease on the
IRIS wireless network. Devices that obtained a
dhcp lease prior to the maintenance will not
be affected. AirBears will not be affected.
Maintenance is scheduled to be completed by
10:30am, but if work goes as planned
it could be completed by 9:40am.
The existing dhcp server at BWRC providing
IRIS wireless support has a corrupted operating
system and will be replaced by another device
during the maintenance.

phpMyAdmin vulnerabilities and scanning
John Ives from the campus SNS (System & Network Security) wrote:
“Everyone,
As many of you may be aware, web based management tools, whether they are used to manage database backends, web content or anything else, are frequently the targets of attacks by would be hackers. In both March an April, phpMyAdmin, a tool for managing MySQL servers via the web, released patches for issues that would allow users to execute arbitrary php code on the server. In the last couple of days, System and Network
Security has seen a marked increase in the number of attackers who have been scanning for these vulnerabilities across campus. This increase also coincides with an increase in phpMyAdmin scanning that has been reported from other sources, like the Internet Storm Center.
If your system runs phpMyAdmin and you have not already applied the March and April patches (see the reference section below), I would urge you to do so, as soon as possible.
Yours,
John Ives

webmail interface to IMAP not responding
The web interface to IMAP (https://webmail.eecs.berkeley.edu) stopped responding to requests. Staff are working on the problem.
Direct IMAP connection to the IMAP server (e.g. using Thunderbird, Outlook, or pine) is not affected.

Exchange email delivery issue
As announced previously to EECS/BWRC Exchange users, the BWRC IronPort anti-spam appliance was scheduled to be moved to the campus datacenter this morning, with downtime expected between 6 am and 7 am.
Kevin Zimmerman has run into some problems getting the IronPort properly installed in the new location, and is working with the vendor to seek immediate resolution. Failing a quick fix, the IronPort appliance will be returned to its previous location, to restore Exchange email delivery service.
The BWRC IronPort generally handles all incoming EECS Exchange email, filtering out lots of spam. For the interim, I have updated forwarding for FONTUS Exchange users, so that new email as of 8:16 should go directly to FONTUS. This will allow normal mail delivery for FONTUS users, but will likely result in a temporary increase in received spam.
No mail will be lost. Email sent during the downtime will be delayed. BWRC Exchange users will continue to have mail delayed until the IronPort is back in service.
Thank you for your patience.

IMAP Service Online
The IMAP Server experienced an unplanned outage while switching from the old LDAP servers to the new LDAP servers.
This was supposed to be a transparent switchover, but we ran into some unforeseen problems that caused the IMAP server to defer mail delivery.
While trouble shooting and fixing that problem users were not able to read mail.
This problem has been resolved.
IDSG regrets any inconvenience this has caused.
