How To Read netstat -a Output
Use netstat -a to
Display Network Status
The netstat command can describe all
current network activity, listing active connections
and listening services.
The format of the netstat output varies from
one operating system to the next.
But netstat output has some common
characteristics across operating systems.
let's see how to read some example output.
TCP is a connection-oriented stateful protocol.
Establishing and shutting down those connections
requires 3-way handshakes, building up and tearing down
each connection by transitioning through multiple states.
A TCP service might be described as LISTENING when
a server process is ready to begin establishing a connection
on that port.
That same port might be in other states as the initial
3-way handshake establishes the connection,
ESTABLISHED when it is up and running,
and in still other states as a 3-way handshake cleanly
shuts down the connection.
Uncooperative clients and servers may lead to other states
as connections are cancelled or abandoned prematurely.
The TCP states are:
CLOSED — Nothing is happening. At the server end, it has not yet started listening, or at the client end, the connection not yet started or has already been completely shut down.
LISTEN — A server transitions into this state without sending any packets.
SYN_SENT and SYN_RCVD — The three-way handshake to establish a connection has started but not yet completed.
ESTABLISHED — The opening 3-way handshake is complete and data streams can flow in both directions.
CLOSE_WAIT, LAST_ACK, FIN_WAIT_1, FIN_WAIT_2, CLOSING and TIME_WAIT — States used to cancel an incomplete connection or to cleanly shut down a established connection, with or without the full cooperation of the other end.
UDP is a datagram protocol in which individual datagrams or messages might be used to stream data but don't build stateful connections.
However, some implementations may show ESTABLISHED for UDP when a stateful application like a DNS resolver has sent a query but not yet received the corresponding reply.

Linux describes the endpoints as host:port
where host is resolved to a fully qualified
domain name and then truncated to 20 characters max,
left as an IP address if the -n option was
used or the hostname does not resolve, and designated
as * for services listening on all IPv4 interfaces.
The port is replaced with the corresponding
entry from /etc/services is there is one,
left numeric if the -n option was used or
their is no entry in the services file.
OpenBSD and Solaris both use "." rather than ":" to separate the host and port. Machines in the same domain are described by hostname only.
Cisco IOS uses a completely different format.
