I did a port scan on my Graphics Client Plus with CE 4.2, and Boot Code 1.83 and it came up with the following active ports - 80, 135, and 443.
I did a port scan on my GCX with CE 4.2 and it came up with the following active ports - 21, 23, 80, 135, and 443.
My question is what are these ports being used for or how would I figure this out, and if I want to disable any of them, how would I do that? |

These are TCP and UDP ports that are open for functions such as FTP, Telnet, HTTP and SSL (one large list of the port functions is posted at http://www.iana.org/assignments/port-numbers ).
In CE, you can close down some or all of the ports using the built-in firewall. Take a look at the information in topic 1795 for details. |

| I added that to the registry for the graphics client plus, and ports 80, 135, and 443 were still active. Should these ports have been disabled by the registry setting? |

You can shut down the HTTP service (or the Telnet, FTP or whatever service) if you're not using them. To shut them down at run time go to a command prompt and type
services -list
to see all the running services. To stop one use the following syntax:
services stop {service}
For example:
services stop HTP0:
All of the server's also have registry keys that can be set to prevent them from starting in the first place. See MSDN Documentation for details:
HTTPD Server
FTP Server
Telnet Server
RAS Server |
