How to select the pcAnywhere registered TCP/IP ports
A pcAnywhere host does not appear on the TCP/IP browse list, or it shows a status of "unknown." However, you can ping the host. and those ping times are normal.
The pcAnywhere use of IP ports changes with the version of pcAnywhere used. Earlier versions used ports 22 (UDP) and 65301 (TCP). These ports were not registered. Beginning with version 7.5, pcAnywhere uses the ports 5631 (TCP) and 5632 (UDP). These ports are registered with the Internet Assigned Numbers Authority (IANA). The following is a brief summary by version:
pcANYWHERE 2.0 uses ports 22 and 65301. With version 2.03 and higher, a download file can change port usage to 5631 and 5632.
pcANYWHERE32 7.0 uses ports 22 and 65301. A download file can change port usage to 5631 and 5632.
pcANYWHERE32 7.5 uses ports 5631 and 5632.
pcANYWHERE32 8.0 and pcAnywhere 9.0 use ports 5631 and 5632, but it will fall back to 22 and 65301 if no hosts are found on 5631 or 5632.
pcAnywhere 9.2 and pcAnywhere 10.0 use ports 5631 and 5632 only.
How to make the changes
pcAnywhere 9.2, pcAnywhere 10.0
Compatibility with ports 22/65301 are removed with this version of pcAnywhere because port 22 is registered with the IANA for the Secure Shell (SSH). While it is possible to configure this version to use ports 22/65301, we recommend that you change the port usage on the older version of pcAnywhere using ports 22/65301.
NOTE: pcAnywhere 10.0 will not connect with pcANYWHERE versions 5.x, or 2.x, regardless of the port assignments.
For information on how to change the ports that pcANYWHERE32 7.5 uses, please see the document How to change the pcAnywhere IP ports.
NOTE: You may not access hosts which are using both the registered and the unregistered ports without making the necessary changes.
Download and run the self-extracting Ports_70.exe file. The accompanying Readme.txt explains how to implement the update for this version of pcANYWHERE. This will change the ports to 5631/5632.
Download and run the Ports_20.exe file. The accompanying Readme.txt explains how to implement the update for this version of pcANYWHERE. You will also make corrections to the Pcaw.ini file located in the \Windows folder.
