SwatCS Help FAQ


access to cs network blocked

Q: I can’t access any of the CS computers. Help!

A: It’s possible your computer’s IP address has been added to our firewall’s blocklist. This is sometimes caused by many failed login attempts.

Please open a browser and search for “what is my ipv4 address”. That should give you a string with 4 numbers and 3 dots, like or (your numbers will be different).

Send that ipv4 address string to us (sysadmins at cs.swarthmore.edu) and we will make sure you are not being blocked by our firewall.
