Wi-fi networks in Soda, Cory, Sutardja Dai, and BWRC are unavailable this morning due to an issue resulting from this morning’s scheduled campus network maintenance. We are working with campus to restore wi-fi service ASAP.
Update 11:45AM: Wi-fi networks should now be back online in all locations. Please let us know at help@eecs.berkeley.edu if you continue to notice any wi-fi issues.
On the morning of Tuesday, October 20th, we will be making significant changes to the behavior of the EECS border firewall. For detailed information about these changes, please see our EECS Border Firewall page (this page requires login).
Update 10/20 07:39: This change has been completed. Please email us at help@eecs.berkeley.edu if you have any questions or notice any network connectivity issues.
For a period between approximately 10/8 14:50 and 10/9 07:40, we had an error in our firewall configuration which was blocking most SSH connections into the EECS network.
The error has been corrected, and SSH connections should be working as expected at this time. Our current firewall policy is to allow SSH connections inbound from the campus VPN and authenticated wi-fi networks (eduroam and Berkeley-IoT); connections from all other sources are blocked.
Please email us at help@eecs.berkeley.edu if you have any network connectivity issues, or questions about our SSH firewall policy.
We believe that DHCP service for EECS wired networks has been restored as of this afternoon (Friday, August 28).
If you have a system on the wired network which cannot obtain an IP address, even after rebooting, please email dcalderon@berkeley.edu with the system’s MAC address and the cable ID it is connected to. Messages sent to help@eecs may not be received.
This morning, June 24th around 7:15 AM, we updated the firewall configuration for our Active Directory and Windows server infrastructure. Please contact us at help@eecs.berkeley.edu if you notice any possible issues.
This morning, June 23rd at 7:15 AM, we made some adjustments to the configuration of the EECS border firewall. We do not expect these changes to have any effect on network traffic, but unanticipated effects may be possible.
Please contact us at help@eecs.berkeley.edu if you notice any network connectivity issues.
We experienced an issue with our DHCP service this morning, which prevented a number of machines from connecting to the wired network. This issue began around 3AM and was resolved by 10:30AM. If your machine still cannot get online, we suggest rebooting it to try and obtain a new DHCP lease.
We believe that this configuration issue was triggered by yesterday’s datacenter firewall issues. We will be improving our scripts to allow us to better detect and mitigate similar issues in the future.
Please contact us at help@eecs.berkeley.edu if you have any questions, or if you continue to experience network issues.
On Monday, March 23rd, we will be adding some new ports to the list of ports that are blocked by the EECS border firewall.
For detailed information about the changes, please see our EECS Firewall Ports page (this page requires login). The list of ports that we will add to the block list is at the bottom of that page.
Update 3/23 8:05AM: These changes have taken effect, and the new ports are now being blocked from off-campus. Please contact us at help@eecs.berkeley.edu if you have any questions or notice any issues.
As of about 11:51 AM: wireless networks are offline due to a power issue in one of the campus network core sites. Wired networks are unaffected and continue to operate normally. We will update again when we have more information about the status of the campus network core.
Update 13:36: Campus has begun restoring power to the network core using temporary connections, so we expect to see some wi-fi service resume. However, wi-fi may experience some continuing instability as the work to restore full power goes on.
Update 17:02: Power has been restored and network services should be fully available. There may be some late-night wi-fi disruptions as staff perform some cleanup work.
Please contact us at help@eecs.berkeley.edu if you have any questions.
Networks on the second floor of Soda Hall were unavailable for approximately 5-10 minutes today beginning at 10:41 AM. This occurred due to a switch crash during troubleshooting a memory leak.
The network is now stable, but the memory leak issue still exists and requires further network disruption to resolve. We will be attempting to address this during tonight’s already-scheduled Soda Hall electrical shutdown.
Please contact us at help@eecs.berkeley.edu if you have any questions.
