NetPro: Packet Analysis and Visualization tool

[jurchiks]

Had a good laugh about that scripting engine example

I see your reasoning (and it's solid), but even so, a wiki and an issue tracker would be much better than this single topic. Besides, the reasons for all the l2jserver forks have been mentioned countless times before; I hope your project is better than that.

The localization should definitely be post-v1, that's for sure. I'm personally all for people learning some English instead of just using whatever they can find in their native language, it's beneficial for everyone after all, especially for those people themselves. You should, of course, first ask around if there's even need for it - if there are only 10 people who want it and each of them speaks a different language, but they all can still use your project as-is, then it's probably not worth it. Just use simple terms and it's going to be ok.

I assume that that "larger project catalog" you mentioned is a commercial product?

In any case, good luck with the project.

Why don't u use javafx its really cool looking and easy to work with.

Also packet injection is kinda nice it helps u gather information that u normally would need to spend a lot of time.
For example while getting skill tree u can request data per each skill level and l2off will give it to you.
And u can use RequestLink to get any html that you know by name (Not only html btw )

Well, javafx is a part of the JDK (vs a rather heavy lib) only since J8; while the UI was created back in 2011 at J6. I've already moved from JEditorPane to WebView due to horrendous performance in J7 (in J6 it was perfectly fine). Anyway, I didn't really have time to assess what would it take to move to JFX. But from what I understand, the performance would be definitely better (though due to the lack of animations that's not really an issue).

Well, I have to admit, I somehow didn't think about harvesting skill learn data
We have our internal scripts (not bundled with this release) to harvest HTMLs, exchanges (a.k.a. multisells), normal NPC spawns, among other things.

I have been unsuccessful in retrieving anything else than .htms with 22, sadly. Except on unofficial servers, of course.

I am using l2tower to inject packets and with packet samurai logging the data and analyzing it

[michael1414]

For a start, I am mainly asking for what features, based on the public opinion, would add the most value to this application.

I tested Your tool and is very good. Here is my feedback.

About the scripts, could be added some scripts about using packets from opcode > 255. Would be very nice.

About the UI features. Firstly, how dumping packets for opening in future ? In scripts ? Or is there option in cmd or export in UI ?. Second: Could be added PAUSE/RESUME for dumping packets (sometimes I want dump packets only for checking one thing and I not need tons of packets).
Next things that could be usefull is filtering packets by Opcode or name (usefull for checking for example packet with opcode 31 is changing), like tere (I made it in Paint so sorry for quality):


For now for me nothing more is not needed.

Thx.

About the scripts, could be added some scripts about using packets from opcode > 255. Would be very nice.

This would be much easier if the javadoc was accessible; however, I am busy with ACM ICPC & related contests/training and have been unable to prepare a guide about script writing.

Let's just sum up that there are two primary script types you will want to use:
A) Low-level packet handling, manually selecting blocking or asynchronous handling. (subclasses of net.l2emuproject.proxy.script.Script)
Blocking implies packet modification (either within the buffer, or dropping the packet, or allocating a buffer of a different size and writing own data). Therefore, since you must know everything (possible opcodes and structures in all client versions your script is being created for), you can only register the 1st opcodes you are interested in. Hardly convenient, but you know how it is: every once in a while, some opcodes get shifted or shuffled around. So if you register all possible variants; you will still have to filter them by version, etc.

B) High-level asynchronous* packet handling, making use of Packet Payload [Field] Enumeration (PPE). You do not specify any opcodes to handle packets. You define script aliases for fields already in packet definitions and when you get a packet event in your script, you can obtain a typed pointer list for each aliased field. Of course, if the definition doesn't specify that field within a loop, then this list will only contain one pointer (to the field). There are functions to read any type of integer value (since we have many D/Q or D/H/C or H/C or C/H field type changes between protocol versions) for your convenience.

* this merely means that scripts receive packet events outside the I/O thread(s); they still handle events one at a time and in the same order packets were sent/received.

That's a short overview of how scripts work. Of course, without a guide (and javadoc), this doesn't help much. I'll try to get to it.

Firstly, how dumping packets for opening in future ? In scripts ? Or is there option in cmd or export in UI ?.

In earlier versions, there was a menu option which would enable/disable automatic packet logging when connections are initiated. Currently, all connections are logged to disk. Packet logs can be found in [user.home]/l2emu-unique-netpro/

Second: Could be added PAUSE/RESUME for dumping packets (sometimes I want dump packets only for checking one thing and I not need tons of packets).

That's a good idea.

Next things that could be usefull is filtering packets by Opcode or name (usefull for checking for example packet with opcode 31 is changing)

Filtering by opcode is currently possible via [menu bar] Packets -> Configure -> Select the protocol version of an active connection. You may check/uncheck packets to include/exclude them from view in the packet table.

I have been thinking about implementing filtering in a more convenient way, similarly to how you have suggested. I'll look into it.

[michael1414]

you can only register the 1st opcodes you are interested in.

Now I understand why my script not worked with 2 opcodes :

Code: Select all

 public final class MultisellFileGenerator extends GameScript{    private static final L2Logger LOG = L2Logger.getLogger(MultisellFileGenerator.class);     private static final int REQUEST_LINK_HTML = 0x22;    private static final int REQUEST_BYPASS_TO_SERVER = 0x23;     private static final int EX_BUY_SELL_LIST = 47358; // FE B8 00    private static final int NPC_HTML_MESSAGE = 0x19;     /** Constructs this script. */    public MultisellFileGenerator()    {        super(new int[] { REQUEST_LINK_HTML }, new int[] { EX_BUY_SELL_LIST, NPC_HTML_MESSAGE });    } 

Thx for informations about scripts. They are very helpfull.

The prereqs are in javadoc. Then you just write '\\dump_multisell 1 300' in the game chat window and wait until multisells are written. Make sure you have examples.game.stealth.PseudoAdminCommandConsumer enabled, otherwise people will see what you are writing

Thanks for this script.

thanks for the script. But anybody have a working script to sniff the buylists.
something like: open buylist -> save buylist in a text file or something else.

thanks for the script. But anybody have a working script to sniff the buylists.
something like: open buylist -> save buylist in a text file or something else.

There is no simple way to sniff the buylist, unless you want it to be written with 0 adena prices.
I had a basic script, but I think I deleted it because it was rather useless (though I must admit, as long as prices are not written, it is faster than manual creation). It is much better to sniff individual item "default" prices via private stores.

[Indra]

it will be cool if he save the buylists like this:

Code: Select all

	<tradelist npc="XXXX" shop="XXXX" markup="XXXX">
		<item id="45493" name="Fishing Rod Pack (30-day)"/>
		<item id="45495" name="Normal Bait"/>
		<item id="38154" name="Fishing Shot"/>
	</tradelist>

and filename = npc name or something to ident it.

New release of 0.8-SNAPSHOT. Most (non-script/definition) changes are cosmetical, so there's no version increment.
This release should directly benefit those that voiced their opinions. I am sorry, I still did not have time to prepare any guides

FastLogin now supports PIN-less definitions.
FastLogin now supports Security Card authorization.
Added additional packet log filtering by regex, accessible right within the packet table. [michael1414]
Added the ability to pause/resume packet logging (capture) to the packet table. [michael1414]
Added IP aliases to be used within the UI (including free samples .
Added a bottom information panel.
Changed L&F initialization to respect a manually set L&F system property, as well as to select the native L&F by default (instead of Nimbus). [LoneRanger]

[REDACTED: download the release listed ion the first post]

P.S. to retain the previous release L&F, modify the launcher bat/sh by adding the

Code: Select all

-Dswing.defaultlaf=com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel

JVM option.

Hi, I want to test your program but I'm facing some problems.

Installed Java version: jre1.8.0_25 x64

After running the NetPro_win.bat I can see the "Please enter your authorization key here".
After entering the key: "HgWjowlGVfLmto3SZPsvUCx+nXjugWqYJdyh6AJiwPM=" I can see for a second the "grumpy cat" logo but nothing else.

Hi, I want to test your program but I'm facing some problems.

Installed Java version: jre1.8.0_25 x64
Tested in SO: Windows 7 and 8.1

After running the NetPro_win.bat I can see the "Please enter your authorization key here".
After entering the key: "HgWjowlGVfLmto3SZPsvUCx+nXjugWqYJdyh6AJiwPM=" I can see for a second the "grumpy cat" logo but nothing else.

Hello there.

Due to the fact that NetPro allows user-made scripts to be presented in source form, you are required to run NetPro via a JDK executable (javaw/java) OR add the JDK's tools.jar to the classpath if running via a JRE.

Now, you might think "I have set up JAVA_HOME ages ago and added that to PATH before system32, so javaw in use WILL be from the JDK".
However, recent Oracle JDK installers have started prepending 'javapath' entries to PATH. So after every installation, you must now manually move your JAVA_HOME related entry before the javapath entry, so that

Code: Select all

where javaw

would look like this:


In any case, I will do a new release, so that a proper warning is shown to the user in this scenario.

Thank you for the report.
