Can someone point me to a reference on what these are? And tell me
whether I should be concerned about them or not?

- Mark

              The source may include a port specification or ICMP
              type.  This can either be a service  name,  a  port
              number,  a  numeric  ICMP  type, or one of the ICMP
              type names shown by the command
              ipchains -h icmp Note that many of these ICMP names
              refer to both a type and code, meaning that an ICMP
              code after the -d flag is illegal.  In the rest  of
              this paragraph, a port means either a port specifi-
              cation or an ICMP type.
