Question netstat output
Hi Team,

Below is the output of netstat -an | grep 1533

Code:
tcp        0      0 17.18.18.12:583       10.3.2.0:1533           ESTABLISHED
tcp        0      0 17.18.18.12:370       10.3.2.0:1533           ESTABLISHED

Below is the o/p of netstat -a | grep server_name

Code:
tcp        0      0 local_server:53083 remote_server:virtual-places ESTABLISHED
tcp        0      0 local_server:39470 remote_server:virtual-places ESTABLISHED


Does port number also changes for "-an" and "-a" options?

If yes how to identify the link b/w
Alphabatic port name (virtual-places) and Numerical port name (1533)

NAME

       tcp.h, tcp - definitions for the Internet Transmission Control Protocol (TCP)

SYNOPSIS

       #include <netinet/tcp.h>

DESCRIPTION

       The <netinet/tcp.h> header defines the following macro for use as a socket option at the IPPROTO_TCP level:

       TCP_NODELAY     Avoid coalescing of small segments.

       The macro is defined in the header. The implementation need not allow the value of the option to be set with setsockopt() or retrieved with
       getsockopt().
