Connectivity Issues for Users


Recently we have been seeing lots of ISPs that do not properly register their DNS entries. As part of our security checks, our software tests to make sure that each host is properly registered before connections are allowed. This has caused problems in some cases. In order to ensure connectivity to users with improperly registered DNS, the lab staff has removed this restriction from the login machines (login.cs.duke.edu). If you experience trouble logging in, please try using the login machines.
