Can't connect to the remote PC and it is black screen

Cause: The security level doesn't match.

How can I list all hosts

To list all hosts in the same subnet, leave blank on the host pc or address. Alternatively, you may type the subnet that the computer is on. For example, if the IP address of the computer is 10.0.0.25, then the subnet is 10.0.0.255.

How to remotely verify if a router's ports are open

If you would like to check to see if the router's ports are open for using pcAnywhere to connect over the Internet to a host that is behind a router, you can use telnet command to do this. For example, type open xxx.xxx.xxx.xxx 5631, where the x's represent the IP address of the router.

If you see the message "Could not open connection" or you see a blank screen with a blinking cursor, then one of the following is true: 1) The ports are closed. 2) You are using the wrong router. 3) The host is not waiting for a connection. 4) You are connecting through a firewall that is blocking the pcAnywhere ports.

 If you see the error "Connection to host lost," then the ports are open but the host is refusing the connection for some other reason. Check for entries in the TCP/IP options that limit connections to specific addresses. To do this, open pcAnywhere>Tools>Options>Host Communications tab. Ensure that there are no addresses entered in the "Limit connections to the following names or IP addresses" field. If there are, either delete them or add the address or name of the remote computer you are trying to connect with.

If you see the message "Please press Enter," then the port is open.

pcAnywhere IP port usage

pcAnywhere uses either of two sets of ports depending on the version of pcAnywhere you are using. One set uses ports 65301 and 22 for the version 2 to 7.51. The second set uses the registered ports 5631 and 5632 for the .version 7.52 or above.

NOTE: pcAnywhere 10.x and 11.0 will not connect to pcANYWHERE versions 5.x, and 2.x, regardless of the port settings.

Which ports should be open on a router or firewall for accessing pcAnywhere

The default pcAnywhere port numbers are 5631 (Data Port or TCP) and 5632 (Status Port or UDP).

Windows XP Internet Connection Firewall prevents pcAnywhere TCP/IP connection

Situation: you may not be able to make a TCP/IP connection to a pcAnywhere host running if you are using XP ICF.

Resolution: In order to run a pcAnywhere Host on a system using ICF, you must add pcAnywhere as a service and enable the service. To add and enable the pcAnywhere service, go to 1) Control Panel>Network Connections, right-click the connection that you are using with pcAnywhere and select Properties>Advanced>Settings>Services>Add, type a name for the service such as pcAnywhere in the "Description of Service" field. 2) Type the Host computer's machine name or IP address in the "Name or IP address of computer hosting this service on your network" field. 3) Type 5631 in the "External Port number for this service" field and 5631 in the "Internal Port number for this service" field. 4) Check the box next to TCP and click OK.
