Help! How to view the current running connections?

[LoveYO]

I want to view the current running connections of my pc, so how?
Would appreciate your advice!

Are you talking dialup or ethernet as in cable modem?
If you check your Network connections in Control Panel, that would give info as to your connection.

On the other hand, if you are asking who and what is passing through your internet connection, that is much more complex.

its easy -

open a command windows and type

netstat -a -n

Thanks, BJ_M, didn't know that one. Now I just have to dig out my port references and see what all those are.

This is what I have in a bat file on my desktop...

BTW, nbtstat comes in handy too

yes - just netstat -a prob. makes more sense for most - I use the -n myself - but same thing , just a different format ..

good bat file to use ..



NETSTAT [-a] [-e] [-n] [-o] [-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.
-o Displays the owning process ID associated with each connection.
-p proto Shows connections for the protocol specified by proto; proto
may be any of: TCP, UDP, TCPv6, or UDPv6. If used with the -s
option to display per-protocol statistics, proto may be any of:
IP, IPv6, ICMP, ICMPv6, TCP, TCPv6, UDP, or UDPv6.
-r Displays the routing table.
-s Displays per-protocol statistics. By default, statistics are
shown for IP, IPv6, ICMP, ICMPv6, TCP, TCPv6, UDP, and UDPv6;
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.

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

This command is even available in *NIX variants... very universal!

You can also use the ipconfig (in C:\windows\system32\) to modify your settings as well. Or winipcfg if your in Win 98.
As you probably know you can test your connection with ping.

For the truly lazy (or those who can never remember command line), try TCPView (freeware).

Also, check out the rest of their freeware, especially Contig and Process Explorer. Very useful software I use regularly.

An easy way is to use a firewall which has a "Net State" function that can show the currently active connections and the details of these connections. I know Armor2net Personal Firewall can do that. You can have a try! http://www.armor2net.com
Hope this help!
