Cory 3F Networks Offline, Morning of Thurs. 4/25

April 24, 2024 by Derek Calderon

Due to planned electrical work, all Cory Hall third floor wired and wireless networks will be offline during the early morning tomorrow, April 25th. We expect the network to be unavailable beginning at 5AM, and all connectivity should be restored by 10AM at the latest.

We apologize for the short notice; the need for this shutdown was only identified this afternoon.

Please contact us at help@eecs.berkeley.edu if you have any questions or concerns.

Microsoft will release their patches for the month on Tuesday, April 9th, 2024. Various IRIS Windows and Linux servers will be patched and rebooted Tuesday or Wednesday.

PRINT, WINTERM and WDS will automatically patch and reboot Wednesday, April 10th, at 3:00am. WINTERM may be unavailable until 10:00am Wednesday, depending on additional software updates.

Linux servers lists.eecs, iris2.eecs (for access to the network and roster databases), and login.eecs will be patched and rebooted Tuesday night. DNS servers cronus and rhea may also be briefly unavailable while rebooting at approximately 8:00pm Tuesday.

On Wednesday, April 10th, the departmental DHCP server is scheduled for downtime from 10pm to 10:30pm (actual downtime is expected to be shorter than scheduled).

Anonymous ftp access ending May 1, 2024

April 3, 2024 by Rob McNicholas

For many years the Department has operated an anonymous ftp server at ftp.eecs.berkeley.edu and ftp.cs.berkeley.edu. Before web sites, this was how software and papers were distributed to the public. Since web sites are the preferred way to distribute digital assets these days, no new content has been published on our ftp servers for over a decade. We will be ending support for anonymous ftp access effective May 1, 2024. After that time, the current contents of our ftp archive will continue to be made available via a web page at https://ftp.eecs.berkeley.edu and https://ftp.cs.berkeley.edu/.

Update: May 1, 1pm: The ftp server has been shut down. The replacement web page is up at https://ftp.eecs.berkeley.edu

NetApp Fileserver Maintenance, Saturday March 30, 2024

March 24, 2024 by Lars Rohrbach

We are scheduling a NetApp ONTAP upgrade, to update our NetApp fileserver, from 8am to 12pm on Saturday, March 30, 2024.

All Home directories and Project shares (CIFS/SMB and NFS) may experience disconnection during the update that may cause data loss on active, open files.  Please close your open files and save them before Saturday Morning. Services (e.g. webservice) that depend on this storage will also be temporarily down or unresponsive.

When maintenance is completed, NFS clients should automatically resume normal operation, but a reboot should help if they don’t. CIFS clients (such as Windows and MacOS) may need to remount filesystems, or simply be rebooted.

Cory 1F and Soda 2F Network Maintenance, Fri. 3/29

March 19, 2024 by Derek Calderon

Between 11AM and 5PM on Friday, March 29th, we will be replacing the access switches which provide wired network connectivity on the 1st floor of Cory Hall (including the mezzanine) and the 2nd floor of Soda Hall.

Wired networks in these locations will experience various interruptions during this time. Most of these interruptions will be brief (<30 seconds), but some cables on Cory 1F/1M will be down for an extended period of time (over an hour). Wireless networks will not be affected.

Primary networking in the server rooms (165 Cory, 287-290 Soda) will not be affected by this work. The exception is the floor boxes in those rooms, which will be affected.

Update 3/29 15:41: This maintenance has been completed and all networks are back online. Please email help@eecs.berkeley.edu if you notice any ongoing network issues.
