yuzhougit / tcpmon Goto Github PK

What steps will reproduce the problem?
1. Start up tcpmon via java web start, listening on port 8888, sending to port 
8080
2. Start up a server that can receive a post request on port 8080
3. Submit a post to the server via tcpmon where the post body contains a very 
large file (such as a 16MB war archive)

What is the expected output? What do you see instead?

Expected:
1. The connection shows up in the table at the top
2. The request should show up in the request area
3. The response should show up in the response area
4. The application should remain functional

Observed:
1. The connection is not displayed
2. After some time the request does show up
3. The response is never displayed
4. The UI stops responding and the program can only be killed via the operating 
system.

In my case I was checking the action of apache httpclient when using FileEntity 
(which does not properly set up a multipart file upload as I had hoped still 
need to do the full MultipartEntity thing after all).

I suggest that you monitor the incoming data and beyond a certain size drop it 
to a temp file. If the user wants to see more than 100k (for example) of data, 
you can write it to a text file for them to view. Note that I am not suggesting 
that you make the binary data readable. That's not your problem, and probably 
not desireable since your tool is supposed to show exactly what transpired over 
the wire.

What steps will reproduce the problem?
1. Double-click the downloaded jar
2. or run: java -jar tcpmon-1.1.jar


What is the expected output? What do you see instead?
App should start.

Hi Indeer,

I'm using your tcpmon tool with my application. I integrated your jar but am

client, i got quickly. Kindly help me to fix it.

(Thanks to Lalitha for reporting this issue).

It will be great to have a text-based interface that doesn't use Swing. This
will be useful on headless servers on which tcpmon gives out the following 
error:

Need a new button to save the request or response to a file.

From: http://java.net/jira/browse/TCPMON-11

tcpmon does not handle very large packets. I have a web request which comprises 
2 x 20 element arrays, 3 x 2000 element arrays, 4 x 20 element arrays and a 1 x 
60 element array.

The response displays fine but the request simply displays:

POST / HTTP/1.1
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; MS Web Services Client Protocol 
1.1.4322.2032)
Content-Type: text/xml; charset=utf-8
SOAPAction: ""
Content-Length: 59237
Expect: 100-continue
Connection: Keep-Alive
Host: 127.0.0.1:8080

and nothing else.

From: http://java.net/jira/browse/TCPMON-4

For the convenience of users, whenever a new tab is created, it should be 
selected immediately.

From: http://java.net/jira/browse/TCPMON-7

When a tab is closed the monitoring of the tcp connection for that panel should 
also be stopped.this is really a user-interface issue.

The current implementation of tcpmon displays the data only when both sender 
and receiver have closed their data streams. tcpmon should display data as it 
is flowing on the network. This problem is exacerbated for browser connections 
that use keep-alive.

What steps will reproduce the problem?
java -jar tcpmon-1.1.jar

What is the expected output? What do you see instead?

Failed to load Main-Class manifest attribute from

Please provide any additional information below.

Hi,
is the tcpmon jar also available at the Central Maven Repository? If not, is it 
planned to put it there?

Regards,
Stefan

What steps will reproduce the problem?
1. download jar from project home page
2. run executable jar by double click 
3. GUI isn't displayed


What version of the product are you using? On what operating system?
- version dated 25/11/2013
- Windows 7

Please provide any additional information below.
- potential cause of problem: MainClass isn't present in file Manifest.MF

When server is sending compressed output, it would be helpful if tcpmon could 
uncompress the data.  Ideally, this would be an optional setting such that 
users could see the compressed data stream if desired.

What steps will reproduce the problem?
1. java -jar '/home/me/Downloads/tcpmon-1.1.jar' 

What is the expected output? What do you see instead?
doesn't run as stated "Download tcpmon and simply double-click on the 
downloaded executable jar file to launch tcpmon."
no main manifest attribute, in /home/peter/Downloads/tcpmon-1.1.jar

What version of the product are you using? On what operating system?
1.1
Linux

Please provide any additional information below.
Resolution: add the Main class to the manifest using Maven

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-jar-plugin</artifactId>
                <configuration>
                    <archive>
                        <manifest>
<mainClass>com.codegoogle.tcpmon.Main</mainClass>                            
                        </manifest>
                    </archive>
                </configuration>
            </plugin>

should be possible to increase the size of either of them. Best done with a 
slider. The table should be smaller than the other two. Check out what happens 
when you maximize tcpmon.

What steps will reproduce the problem?
1. Downloading the jar
2. Running it locally
3.

What is the expected output? What do you see instead?
Expect to run. Runs from web.
Failed to load Main Class Manifest attribute from the jar.

It would be nice if there were a way to search the contents of the two traffic  
windows. Something that worked like FireFox's QuickFind (hitting '/'), or a 
standard Ctrl-F dialog.

The thread-usage can be cut down significantly by using nio.

Looks like the jar was built with older sources. 

Very useful tool btw. Thanks for writing it.

What is the expected output? What do you see instead?
Add column to see response time
