tcpproxy 'failed to connect' errors

Hello,

 

I’m very new to Grinder and am in need of some guidance, and I apologize upfront if this seems elementary.  I’m trying to use the TCPProxy tool to record some user interactions with my company’s web site, so I can conduct some load, capacity, and stress testing.  I’ve reset my proxy to localhost:8001 as the directions instructed.  When I initialize the TCPProxy to record the session though (yes I have set my classpath), I immediately get a 502 connection refused – failed to connect error. 

 

I should explain that we use third-party JS and CSS libraries from google and yahoo.  Upon setting my proxy to localhost:8001, with NO TCPProxy initialized, I get this: I can go through the basics of a login and navigation of the site and it works just fine—no errors.  But, with the TCPProxy initialized I get this:  I immediately get a 502 error telling me failed to connect to… and connection refused. 

 

This is the exact error message (with multiple iterations): Failed to connect to www.google-analytics.com:80, and (Connection refused: connect).

 

I’m obviously at a loss and am under a very aggressive timeline.  If I can provide any more info or anyone has any questions, please let me know.  Any assistance anyone can provide would be very much appreciated. 

 

Best,

 

Lisa

When you mention “I’ve reset my proxy to localhost:8001”, you mean the proxy settings in your browser right?

 

As far as I remember, I overrode the proxy settings of my browser to use HTTP Proxy: localhost, using port: 8001. Thereafter, I launched the TCPProxy application and then accessed any website for which I needed to record a browsing session.

 

Are you doing all these things as well?

Yes, I meant resetting the proxy settings in my browser.  Sorry about that, I should have been more clear.  It seems like it should be relatively straight forward but I’m not able to access those third-party libs once the TCPProxy app is launched.  Just curious but when you say that you “…then accessed any website for which I needed to record a browsing session…”, were you referring to Intranet or Internet sites?

I think I know what’s wrong but I will likely need to add network authentication information to get this to work.  What file(s) would I put that info in?

I have it working now and I can get to the Internet and roam around, but when I try to hit our customer-facing web site from the Internet, this error shows up in the stacktrace.  I’m not even sure it’s negatively impacting anything but I can’t say that I really know what I’m doing yet either.  Has anyone ever seen this and what is the cause, impact, and resolution?

 

Thanks,

This error means that a Java regular expression did not match the input text.

A call to Matcher.group() was made although a previous .find() or .match() didn't find anything. But then, considering it occurred within the Grinder API @ URIParserImplementation – it might be that there is something about your client’s web-application’s URI which leads to this problem.

 

I fear I’m not in a position to accurately discuss about the impact and resolution of this problem. Probably someone from Grinder’s core dev team will be able to help you better.

I'm interested in the URI that failed to parse.

Please add the attached patch to the beginning of your CLASSPATH and re-run your test. This will include the URI in the exception.

Thanks,

I think I know what’s wrong but I will likely need to add network authentication information to get this to work.  What file(s) would I put that info in?

Yes, I meant resetting the proxy settings in my browser.  Sorry about that, I should have been more clear.  It seems like it should be relatively straight forward but I’m not able to access those third-party libs once the TCPProxy app is launched.  Just curious but when you say that you “…then accessed any website for which I needed to record a browsing session…”, were you referring to Intranet or Internet sites?

When you mention “I’ve reset my proxy to localhost:8001”, you mean the proxy settings in your browser right?

 

As far as I remember, I overrode the proxy settings of my browser to use HTTP Proxy: localhost, using port: 8001. Thereafter, I launched the TCPProxy application and then accessed any website for which I needed to record a browsing session.

 

Are you doing all these things as well?

Hello,

 

I’m very new to Grinder and am in need of some guidance, and I apologize upfront if this seems elementary.  I’m trying to use the TCPProxy tool to record some user interactions with my company’s web site, so I can conduct some load, capacity, and stress testing.  I’ve reset my proxy to localhost:8001 as the directions instructed.  When I initialize the TCPProxy to record the session though (yes I have set my classpath), I immediately get a 502 connection refused – failed to connect error. 

 

I should explain that we use third-party JS and CSS libraries from google and yahoo.  Upon setting my proxy to localhost:8001, with NO TCPProxy initialized, I get this: I can go through the basics of a login and navigation of the site and it works just fine—no errors.  But, with the TCPProxy initialized I get this:  I immediately get a 502 error telling me failed to connect to… and connection refused. 

 

This is the exact error message (with multiple iterations): Failed to connect to www.google-analytics.com:80, and (Connection refused: connect).

 

I’m obviously at a loss and am under a very aggressive timeline.  If I can provide any more info or anyone has any questions, please let me know.  Any assistance anyone can provide would be very much appreciated. 

 

Best,

 

Lisa
