I’m trying to use the TCP/IP Monitor. The site I’m trying to monitor uses SSL and authentication. It seems that it doesn’t work with the TCP/IP monitor that comes with it.

Example:
URL: https://some.ip/path/to/app

Using Jakarta Commons HttpClient to make connection and set authentication information. I can access the app fine.

Now, I want to Monitor this connection. So I set my URL to:
https://localhost:444/path/to/app

I setup TCP/IP Monitor like this:
Local Monitoring Port: 444
Monitor:
Host: some.ip
Port: 443
Type: HTTP (HTTPS isn’t an option).

It never connects. Is it the SSL that’s causing problems? If so, and TCP/IP Monitor doesn’t support this, anyone have a suggestion on what else to use?

Well, I don’t know, what useful you would see of a SSL encrypted (e.g. https) connection if looking at it.

Also if you try to connect with a non-SSL capable client to a HTTPS service, you won’t be able to complete the SSL handshake, and therefore obviously you don’t see anything useful.

Definitely not from the server, since if you are not providing a proper initiation of the SSL handshake, then it probably just aborts the connection, without writing anything into it. At least that is what has happened when I just wrote junk into a HTTPS service.

The HttpClient (jakarta commons) does SSL. It works, I’m just having some funky problem that I need to read the headers. Come to think of it, I bet HttpClient uses Log4J, so I”ll experiment with that.

In fact, its well documented here:
http://jakarta.apache.org/commons/httpclient/logging.html

I realize this is old thread but I am having an issue with MyEclipse TCP/IP monitor
In MyEclipse,
Window-> Show View -> Other -> Debug -> TCP/IP monitor

It opens TCP/IP monitor in view mode
Click on top right ( V symbol) View menu
It show – Show headers and Properties

Clicking Properties does nothing
but I see an error in logs

Dave,

I see this too, in MyEclipse 2020.05 – thank you for the report. I must admit, we don’t have many users using this capability. Were you successfully using the monitor in earlier versions of MyEclipse or is this the first time you’re trying it?

[daveONE]

This is first time trying this TCP Ip monitor. if it works, it can be invaluable to analyze traffic between to any two Rest end points. Is there any other plugin that provides this feature ?
