How to Troubleshoot Connection Problems

Many factors affect connections between CA Access Control computers. Connection problems include being unable to connect to a remote CA Access Control computer, or the connection to the remote computer timing out. The following process helps you identify the cause of the connection problem.

Note: For assistance, contact CA Support at http://ca.com/support.

1. Check the CA Access Control computers for recent changes to the following:
   • Encryption key
   • Encryption method
   • TCP and UDP ports
2. Review any new or recently changed rules in the TCP, CONNECT, HOSTNET, or HOST classes.
3. Determine the port that has the connection problem.
4. Run a trace and review the trace file for:
   • Connections that CA Access Control blocked due to TCP rules or other rules
   • A code other than P (permitted) next to the port number that has the connection problem
5. Review the CA Access Control audit log for D (deny) records that refer to the problematic port.
6. Check that firewalls do not block the problematic port.
7. Review the log files for your OS for error messages that are caused by ports that cannot bind.
