PC-Anywhere sends UDP ping looking for a server on ports 22 and 5632. If it doesn't know the server address, it will ping the entire subnet to find one !.
If you're running PC-Anywhere, make sure that you assign exact IP addresses of the systems that will be using it in the configuration, to avoid PC-Anywhere scanning an entire IP range looking for "your target system" and essentially advertising the service to every potential intruder in your IP block.
Symantec pcAnywhere 8.0 allows remote attackers to cause a denial of service (CPU utilization) via a large amount of data to port 5631.

The host-services component in Symantec pcAnywhere 12.5.x through 12.5.3, and IT Management Suite pcAnywhere Solution 7.0 (aka 12.5.x) and 7.1 (aka 12.6.x), does not properly filter login and authentication data, which allows remote attackers to execute arbitrary code via a crafted session on TCP port 5631.

SANS ISC: port 5631
Notes:
Port numbers in computer networking represent communication endpoints. Ports are unsigned 16-bit integers (0-65535) that identify
a specific process, or network service. IANA is responsible for internet protocol resources, including the registration of commonly
used port numbers for well-known internet services.
Well Known Ports: 0 through 1023.
Registered Ports: 1024 through 49151.
Dynamic/Private : 49152 through 65535.
TCP ports use the Transmission Control Protocol, the most commonly used protocol
on the Internet and any TCP/IP network. TCP enables two hosts
to establish a connection and exchange streams of data. TCP guarantees delivery of data
and that packets will be delivered in the same order in which they were sent.
Guaranteed communication/delivery is the key difference between TCP and UDP.
UDP ports use the Datagram Protocol. Like TCP, UDP is used in combination with IP (the Internet Protocol)
and facilitates the transmission of datagrams from one computer to applications on another computer,
but unlike TCP, UDP is connectionless and does not guarantee reliable communication; it's up to the application that received
the message to process any errors and verify correct delivery. UDP is often used with time-sensitive
applications, such as audio/video streaming and realtime gaming, where dropping some packets is preferable to waiting for delayed data.
When troubleshooting unknown open ports, it is useful to find exactly what services/processes are listening to them.
This can be accomplished in both Windows command prompt and Linux variants using the "netstat -aon" command.
We also recommend runnig multiple anti-virus/anti-malware scans to rule out the possibility of active malicious software.
