Status: Verified
GOAL:
What is Progress's position on the use of port scanners?
GOAL:
Are port scanners acceptable for monitoring ports being used by Progress executables?
GOAL:
Is it okay to use port scanner packages with Progress?
FACT(s) (Environment):
Progress 9.x
OpenEdge 10.x
FIX:
Progress Software does not recommend the use of port scanning software.
Port scanning software can send packets to a remote host as a TCP ping. These types of packets could cause Progress database servers to terminate. The Progress database server verifies each message it receives on the socket it is listening on. If that message does not contain the identifiers that confirm the expected origin of the message (a remote client), the server considers the socket unreliable and will close down the connection.
