# # File System Port Restriction File # # The fsports file provides a way to constrain the TCP and UDP # ports used by the SNFS server processes. This is usually only # necessary when the SNFS control network configuration must pass # through a firewall. Use of the fsports file permits firewall # 'pin-holing' for improved security. If no fsports file is used # then port assignment is operating system dependent. # # If an fsports file exists in the SNFS 'config' directory it # restricts the TCP and UDP port bindings to the user specified # window. The format of the fsports file consists of two lines. # Comments starting with pound-sign (#) in column one are skipped. # # MinPort # MaxPort # # where is a number. The MinPort to MaxPort values define # a range of ports that the SNFS server processes can use. Be careful # to choose port range values that are appropriate for your operating # system. The Internet Assigned Numbers Authority (IANA) suggests # dynamic port range values from 49152 through 65535. See the fsports # man page for more detailed information. # # Example: # # Restrict SNFS server processes to port range 52,000 to 52,100: # # MinPort 52000 # MaxPort 52100 #
