A knowledge base article about How to access the list of hosts that are blocked from the campus network provided by the UC Berkeley IT Service Hub - Knowledge Portal
The Information Security Office (ISO) maintains a list of hosts that are blocked from the campus network. IP and MAC blocks may be viewed by anyone with a valid CalNet login; however CalNet UIDs blocked from the eduroam network and/or VPN are only available to specific IT support staff.
Some ports are blocked by default on the campus networks: 137/tcp, 138/tcp, 139/tcp, 445/tcp, 69/udp
You can track open ISO security issues related to each blocked host.
If you provide technical support to the campus and need access to the Block UID list, have your supervisor email a request to socreg@berkeley.edu. They will need to include your department name, the reason you need access, and their approval.
If you believe your account or computer has been blocked because of a security alert please look for an email from: 'Security Operations via RT <security@berkeley.edu>' and respond to that email.
Please include the ISO ticket number [ISP #11xxxxx], with brackets in the subject line.
Once all security issues have been resolved, email security@berkeley.edu and include the following in the Subject line of your message:
ISO security notice tracking number including the enclosing brackets from the original security notice you received from ISP
IP address or Mac Address that is currently blocked
Subject: Block Removal Request - 192.168.1.1 [INC#1000000]
Subject: Block Removal Request - 00:11:22:33:44:55 [ISP #1000000]
