start > run

When I enter netstat -an, the screen literally flashes for a
split second and vanishes. Why?


Practice safe eating - always use condiments

You have to open a command prompt first. Netstat is a commandline utility, not a windowing
GUI utility.

Go to; Start -- run
execute; command.com

Now execute; netstat -an

If you use netstat with parameters from Start Run, it will flash a DOS box and
close.
Run it from Start Programs MS-DOS Prompt.

Here are the available parameters, which can be seen by typing:
netstat /?
at the DOS prompt -

NETSTAT [-a] [-e] [-n] [-s] [-p proto] [-r] [interval]

-a Displays all connections and listening ports.
-e Displays Ethernet statistics. This may be combined with the -s
option.
-n Displays addresses and port numbers in numerical form.
-p proto Shows connections for the protocol specified by proto; proto
may be TCP or UDP. If used with the -s option to display
per-protocol statistics, proto may be TCP, UDP, or IP.
-r Displays the routing table.
-s Displays per-protocol statistics. By default, statistics are
shown for TCP, UDP and IP; the -p option may be used to specify
a subset of the default.
interval Redisplays selected statistics, pausing interval seconds
between each display. Press CTRL+C to stop redisplaying
statistics. If omitted, netstat will print the current
configuration information once.

Thanks, Dave... it worked perfectly! I was able to use the
print screen button and pasted the information into word to
analyze it.

I'm trying to educate myself about ports. How do I tell
from those numbers which port is open on my computer? I was
trying to find port 5180, the one that Netscape uses (I am
assuming that Mozilla/Firefox use the same port).

For instance, I think Established means a port is open...
but which one? Is it the number following the : in the left
column? I also know that 127.0.0.1 is my computer, so I'm
assuming ZA is doing its job.

TCP 127.0.0.1:1152 127.0.0.1:1153 ESTABLISHED
TCP 127.0.0.1:1153 127.0.0.1:1152 ESTABLISHED
TCP 127.0.0.1:143 0.0.0.0:0 LISTENING
TCP 192.168.250.3:1151 204.127.204.17:119 ESTABLISHED
TCP 192.168.250.3:1164 209.247.153.137:80 ESTABLISHED
TCP 192.168.250.3:1165 209.247.153.137:80 ESTABLISHED

TIA

A better utility to use is TCPVIEW.EXE -- free from SysInternals @
http://www.sysinternals.com/ntw2k/source/tcpview.shtml

It is a GUI utility.
