Port 21 needs to be open for FTP, and ports 1709 and 80 need to be open to attend an online training class.

To verify port 21 is open for FTP:

  1. Click Start, Run, and type telnet.
     
  2. On the DOS screen that opens, type open ftp1.blackbaud.com 21.
     
  3. If the screen then goes black, the connection is open. If you receive an Error: Connection failed, the port is being blocked by some other service.
     

To verify ports 1709 and 80 are open for www.blackbaud.com or online classes:

  1. Click Start, Run, and type telnet.
     
  2. On the DOS screen that opens, type open bbtraining.blackbaud.com 1709.
     
  3. If the screen then goes black, the connection is open. If you receive an error: connection failed, the port is being blocked by some other service.
     
  4. Repeat for port 80.
    Note: To attend CENTRA classes both ports 1709 and 80 must be open to outgoing traffic (TCP/IP).
