Cory Hall Network Maintenance, Mon. 5/16 5-7AM

by

Between 5 and 7AM on Monday, May 16th, we will be performing firmware upgrades on various Cory Hall network hardware. Wired networks will be unavailable for approximately 15 minutes beginning at 5:00AM. Wireless networks will experience a number of interruptions throughout the two hour period. We expect all connectivity will be restored by 7AM.

We recommend system administrators check their systems on Monday morning after 7AM to verify they are working as expected. Some systems or services, such as nfs mounts, may need to be restarted.

This maintenance is complete as of 6:30AM. Please contact us at help@eecs.berkeley.edu if you have any questions, or notice any lingering issues.

Jacobs Hall Network Outage, 5/8

by

We are investigating an outage of Jacobs Hall wired networks which began approximately 2:30AM on May 8th. We currently believe that wi-fi is unaffected. An update will be posted this afternoon when we have more information.

Update: All Jacobs Hall network service was restored shortly after 2PM. Please email help@eecs.berkeley.edu if you notice any continuing issues.

Wi-Fi Compatibility Issues with Newer wpa_supplicant Versions, including Ubuntu 22.04

by

We’ve confirmed an issue affecting Linux wireless clients using wpa_supplicant version 2.10, which includes the already-released Ubuntu 22.04. These clients are unable to connect to both eduroam and EECS-Secure due to an incompatibility in TLS negotiation methods.

We are working with our vendor to see if the eduroam and EECS-Secure authentication servers can be updated to comply with the relevant RFC. Some Linux distributions, including Ubuntu 22.04 and Fedora 36, are working on patches to address this issue from the client side.

Until a fix is deployed for your distro or our software, we suggest those affected by this issue employ the fix described in this link:

Our thanks to Alex Reinking, a member of the EECS community, who first reported this issue and also provided the fix linked above.
This post was updated on May 5th with newer information and to correct some errors.

Announcing Retirement of the EECS-Secure Wireless Network

by

EECS-Secure Broadcast Ceases May 16

On Monday, May 16th, at 7AM we will cease public broadcast of the EECS-Secure wireless network. The network will continue to exist and devices already configured to use it will be able to continue to do so. However, it will not be available as a visible option to new devices which are not currently configured to connect to EECS-Secure. In other words, EECS-Secure will become a hidden SSID.

We recommend users of EECS-Secure begin transitioning to eduroam effective immediately. Information about how to connect to eduroam is available at:
https://technology.berkeley.edu/wi-fi

Please read the full post below for more information.

Soda 3F Wi-Fi Outage, 4/4/22

by

Wi-Fi networks for a large portion of Soda Hall third floor are offline since 7:20 this morning due to a switch failure. Staff are currently in transit to install a replacement.

Update 11:27: Wi-fi service in most areas was restored around 10:35. The remainder was restored at 11:25. Please contact help@eecs.berkeley.edu if you notice any ongoing issues.

Firewall Migrations for IRIS NetApps and Instructional Servers, 3/21 6AM

by

At 6AM on Monday, March 21, we will be migrating the following networks to our new border firewall:

169.229.3.96/27 (Instructional Support Group servers)
169.229.3.128/26 (IRIS NetApp file servers, including home and project shares)

There will be a brief interruption to these networks as they are migrated. This will affect all home, project, and other file storage provided by the IRIS NetApps. After the migration, we encourage system administrators to test that connections to the NetApps are behaving as expected. Some file service clients may need to be rebooted or have their nfs service restarted.

Please contact us at help@eecs.berkeley.edu with any questions or concerns.

Firewall Migrations for Soda and Cory Server Networks, 3/14 6AM

by

At 6AM on Monday, March 14, we will be migrating these wired networks to our new border firewall:

128.32.244.0/25 (165 Cory restricted network)
128.32.244.128/25 (290 Soda restricted network)
128.32.128.0/24 (290 Soda virtual machines)

There will be a brief interruption to these networks as they are migrated. This will also affect various IRIS services such as hosted web sites and winterm. After the migration, we encourage system administrators to test that traffic across the firewall is behaving as expected.

Please contact us at help@eecs.berkeley.edu with any questions or concerns.

Jacobs and HMMB Firewall Migrations, 3/7 6AM

by

At 6AM on Monday, March 7, we will be migrating these wired networks to our new border firewall:

169.229.62.0/24 (Jacobs Hall)
169.229.63.0/25 (BiD Lab in HMMB)

There will be a brief interruption to these networks as they are migrated. After the migration, we encourage system administrators to test that traffic across the firewall is behaving as expected.

Please contact us at help@eecs.berkeley.edu with any questions or concerns.

EECS Network Maintenance, 2/25 6AM

by

Tomorrow morning, 2/25 at 6AM, we will be rebooting the Soda Hall core router in order to apply a configuration change which will resolve an issue currently affecting a small portion of network traffic. As a result, we expect most EECS network paths will be unavailable for up to 15 minutes beginning at 6AM. Some systems or services (e.g. nfs) may have connectivity issues and may need to be restarted or rebooted after this maintenance.
