content: Can anybody help me to setup network connection between Win10-PC and oscilloscope (Agilent DSO6000)?I used a cross over LAN cable to connect, set all the network settings (IP, Subnet etc.) on o'scope and PC, but when I used ping at CMD window I alway get "timeout error".The PC is a notebook of my employer, I don't know if it is restricted regarding network settings or something.I use WLAN to connect www. Local LAN was unused so far.Do I have to unblock firewall, or open ports etc? -PS: noPS:Problem #1 solved:VPN deactivated-> Ping to IP works!I also can open the o'scope's website in the browser.Next problem:Java is deactivated-that's what the o'scope's website replies, when I click "Remote Front Panel" (using MS Edge and Google Chrome browser).Java script is active, so how to activate Java? Tried using the Group Policy Editor, but I cannot find a key to activate Java...Sorry, I'm a real noob regarding networking...

content: Another website, that checks javascript, stated: "javascript is activated".Java is the problem, not javascript.Installed Java version is 1.8.0_261

content: Java by default is very closed up.You must allow and activate all the connections you are using inside of JavaThen it will work.

content: Can you explain, how to do that?"Java is deactivated" is a message from the browser.Maybe this is the Problem?Quote(Keysight_6000A_5000A_Oscilloscope_Release_Notes_0620.pdf)My scope's firmware is ver 6.16.0001.Is it incompatible to installed Java version 1.8.0_261 ?

content: Is there a way to backup installed firmware from scope via telnet?Or is the version 6.16.001 available via download?All I found at Keysight website was 6.20.

content: Personally, I would set up a VM with the JRE to enable the software to run due to the security issues related to an internet-facing JRE.That said, there will be a security setting in your browser that enables the JRE to run downloaded Java applets - This isn't JavaScript, it'll be related to Java and the ability to run an external component.As an aside, for one of my scopes I did run up a VM with Java installed to see what the software did and in the end, I thought it wasn't worth it - I find it better to just use the GPIB interface to control the scope.TonyGEDIT: Thinking about it the setting might be in the Java security panel but it's been ages since I installed a JRE on any of my machines.

content: I had the chance to check another scope, a DSO5034A, latest Firmware 06.20.0000.Same problem, so it cannot be a compatibility problem between firmware and PC's installed Java version.

content: I just installed it on a VM and it is now called "Configure Java" - It'll be in the Java folder in the apps list.EDIT: Adding some images to help you find it - Here is where it is on the start menu:And here is the control panel running showing that Java is enabled in the browser:You probably want to check the security settings to make sure that it can run the code.TonyG

content: Thank you Tony!Quote from: Tony_G on November 14, 2020, 01:49:47 amIt seems not to be there:I used the search function - this was the result:Then I executed it, a console window opened (cmd) and closed immediately.I opened a new console window and typed "java -version":What was going wrong?

content: I just installed the latest version from Oracle:I'd try running the removal tool to get rid of that -https://java.com/en/download/uninstalltool.jspAnd install the latest bits fromhttps://java.com/en/download/Then see what happens.EDIT: It's been a very long time since I used Java so it just occurred to me that you might have installed just the JRE (Java Runtime Environment) whereas I installed the full Java SDK (Software Development Kit). The JRE only has the bits needed to run Java apps as compared to all the tools that the SDK has. Typically the JRE is chained into app installers so it is minimal size.TonyG

content: Thinking about it, you might also want to try another path (I wouldn't recommend this for a main machine as Java is notorious for security issues in much older versions).1. Find out when the scope firmware was released.2. Find the corresponding Java version fromhttps://www.codejava.net/java-se/java-se-versions-history#:~:text=Java%20SE%20versions%20history%20%20%20Java%20SE,%20May%202000%20%2013%20more%20rows%203. Download and install that version4. Make sure it works from your browser (I'd use IE or Chrome rather than Edge)TonyG

content: I can only speak from memory from about 2016.But I remember that I had installed the latest Keysight firmware and the latest JAVA.It took me a long time to get it working but once I had found the securitytabs, made the scopes IP address a security exception and reduced all other securityissues in JAVA to low. After a lot of tweaking it workedI could not stop shaking my head in disbelieve.What was Agilent thinking, when they implemented such complicated system.Or maybe JAVA was easier when the 6000 and 7000 series scopes came out.

content: Quote from: HighVoltage on November 15, 2020, 03:52:54 pmThat probably was scope firmware 6.16 and Java SE 8, 1.8 (came out in March 2014).Quote from: HighVoltage on November 15, 2020, 03:52:54 pmMaybe Java was easier at this time, but why is there no guaranteed downward compatibility for newer Java versions?Years ago I had another tool complaining Java version. Solution was configuring Java settings compatible to older versions, but I can't remember, how this was done.
