If this is half as good as I think it is good job.

I tried to listen on port 80 - nothing showed up and my IE was working ^_^

XXX.XXX.XXX.XXX:80/

Your IP:80

Here's a screenshot. It's a newer version, but will return the same thing as posted version above.

Posted Image

EDIT: Released new version.

Added:

-Saving Packets

-Source IP

-Removed Asc (useless)

-Improved networking

-Fixed multi connections

Looking great glad it worked out lol

Your IP:80

I guess I'm "blind" and I can't see what you mean.

Better have a look at the code you have posted and see if anything is wrong.

Your input accepts only port numbers and the only refference to an IP address is in:

Local $Server = @IPAddress1

The code doesn't work for me.

TomCat · May 8, 2009

Nice ^_^

Some Question: Can you add support for UDP Packets too ?

MerkurAlex · May 8, 2009

I believe he was telling you how to connect to the packet viewer with a browser...

so run packet viewer on port 80 and then open firefox or IE and enter "http://192.168.1.10:80/" that is of course assuming your local ip is 192.168.1.10... note: i have found its best if you use the 192.168 ip and not 127.0.0.1 as it will not connect(for me and firestorm at least)

Skrip · May 8, 2009

Also, that port may need to be forwarded.

MerkurAlex · May 8, 2009

Also, that port may need to be forwarded.

Only if your not local in other words if you want someone outside your house/network to connect it must be forwarded and they must use the outside ip(from whatismyip.com)

FranckGr · May 8, 2009

If you have 2 NICs on your computer, your problem can also come from the NIC order (Socket used = @IPAddress1+Port). You can change it in Network connections properties / Menu=Advanced / Advanced parameters (My XP is French but I think it is the good translation). Here you can change the NICs order. You can verify with IPConfig in a DOS box. ^_^

Skrip · May 8, 2009

I'm not sure what you mean. I only have one NIC, so I can't really test. Should I add an option to select @IPAddress1-4? Is that what you meant?

FranckGr · May 9, 2009

I'm not sure what you mean. I only have one NIC, so I can't really test. Should I add an option to select @IPAddress1-4? Is that what you meant?

I have one NIC (hardware) and a second (Virtual NIC from Sun VirtualBox) and only the first one displayed by IPCONFIG (IPAddress1:PortNb) is seen by PortMonitor.

I'm using Telnet IPAddress1 PortNb and Telnet IPAddress2 PortNb to test.

My XP (for security) is not routing at all between NICs, so the TCP Stack is not routing IPAddress2:PortNB to IPAddress1:PortNb.

So yes, adding an option with @IPAddress1-4 would be nice, with a default set to @IPAddress1 (And may be a _GUICtrlListView_DeleteAllItems($List1) )

Nice program anyway ...

Skrip · May 9, 2009

Released an update with some IP settings, and I added the feature to clear the packet list.

enaiman · May 10, 2009

XXX.XXX.XXX.XXX:80/
Your IP:80

run packet viewer on port 80 and then open firefox or IE and enter "http://192.168.1.10:80/"

Nice translation MerkurAlex I'm glad you understood that language because it was beyond my understanding.

Thank you for making that clear :party:

Skizmata · May 11, 2009

That is amazing I have learned allot from reading your code (not just this code). Thank you firestorm for sharing. Just for fun at the office I added the following 3 lines

Dim $oSp = ObjCreate("SAPI.SpVoice")

$aData = StringSplit($data,@CRLF)

$oSp.speak(StringReplace(StringTrimRight(StringTrimLeft($aData[1],5),9),"%20"," "))

to _Monitor() so I could make my system talk to people while locked down from the other room. Fun stuff and very informative. Thanks again!

Everyone got a good laugh in the office.

Skrip · May 11, 2009

Haha, awesome! Never would have thought to do that. Glad you like it.
