Ping Strangeness

Ping
strangeness is a term used in troubleshooting to describe the
incidence of an unusual pattern of ICMP ECHO_REQUEST packets being sent to a
specific network node or an unusual number of error messages returning.
Ping (Packet Internet Groper) is a utility
program that allows a user or program to verify that a particular IP address
exists and can accept requests. Ping can be used as an alternative to the
traceroute utility to troubleshoot network connectivity and latency issues.
It is faster than traceroute and generates less network traffic.
When a user issues a ping request, the
program formats an ICMP ECHO_REQUEST packet and sends it to a designated
target address. If the remote IP address is active, it responds with an ICMP
ECHO_REPLY packet. Ping then uses the timestamp of the Echo Reply to
calculate a round-trip time and gauge response time.
If the target address is unavailable or
something else is not working normally, Ping will report an error. Common
errors include Destination Unreachable, Unknown Host and Request Timed Out.
When there is an unusual pattern of ICMP
ECHO_REPLY packets being sent to the same server in the same time period, or
there is an unusual number of error messages, this "strange"
pattern is worth investigating. It could be that Ping is being used to carry
out a denial of service attack (DoS) or look for attack vectors.
