Not able to see http traffic on mono Fiddler(v4.4.8.4)

[sandeep goyal]

Hi,

On Windows machine, I have used the below command on window terminal:

set JAVA_OPTS=-Djava.net.useSystemProxies=true

and start my application and I am able to see all http traffic . I can modify it using FiddlerScript and everything is working perfect.

Now I want to do the same thing on Ubuntu 16.04. I have installed the mono and fiddler(v4.4.8.4). I can see the c# script in Customize rule getting loaded.

However when I issue  the  below command on Ubuntu terminal

export JAVA_OPTS=-Djava.net.useSystemProxies=true

and then stat my application, I can not see any http traffic related to my application.

I am able to see 200 response for Fiddler echo service(127.0.0.1:8888).

Could you please help me on that?

can anybody help me on this?

Rather than trying to set the option useSystemProxies, why not explicitly tell Java what proxy to use?  e.g. something like

java -DproxySet=true -DproxyHost=127.0.0.1 -DproxyPort=8888 -Dhttps.proxyPort=8888 -Dhttps.proxyHost=127.0.0.1 -Djavax.net.ssl.trustStore=<path to FiddlerKeystore> -Djavax.net.ssl.trustStorePassword=<password> -jar test.jar

Hi Eric,

I have appassembler script(whuch internally contains all the classpath for Java jar).

Currently I tried Below command

export JAVA_OPTS=-DproxySet=true -DproxyHost=127.0.0.1 -DproxyPort=8888

and then executes my appassembler script

\sam\abc

but didn't see any http script.

on the other hand, on windows 10, I am using below command :

set JAVA_OPTS=-Djava.net.useSystemProxies=true

and then executes my appassembler script

/sam/abc.bat

and I can all http traffic on fiddler.

sorry for the type above:

but didn't see any http script.

should be:

but didn't see any http traffic.

Eric,

Any other suggestion?
