Network Error When Using Avocent KVM
Hi. Thank you so much for creating this solution!
I'm utilizing an Avocent av3008 IP KVM and can make it through all the "verification" prompts, but then get a "Network connect error" when it attempts to connect to the end device (see below).
I get the same connect error whether I open the jnlp file via browser or invoke it from the command line via javaws. Only two messages I visibly see when utilizing the command line, are "This application does not specify a Codebase in its manifest" and "Application title was not found in manifest".
Hoping you can assist with resolving this issue and please let me know what additional info/data/logs might be needed. Thank you!
Haha. Who knows man :)
The network connect error, can you curl that https url in the error message? (it's probably the same url you are visiting)
I would bet it is https cert validation failure.
Maybe there is a way to invoke the java app without the webstart stuff? That might make the real error more obvious.
Maybe try having a conversation about it with ChatGPT?
lol :)
As you suspected, am not able to curl the http link, but can successfully curl it via https. Also, I'm a n00b when it comes to Java... what command would I run to invoke the java app without webstart?
Also, trying to find a solution on ChatGPT as well. Thank you!
I ran into this problem, and it seems to be an incompatibility issue between IcedTea-Web and the Avocent/Dell JNLP. The solution I found so far: replace IcedTea's javaws with the original Oracle Web Start; in short, download the Java 7 JDK from Oracle's official website (you need the x64 .tar.gz version), extract it, and copy the javaws binary to /usr/bin. With that, the KVM works with this Docker container.
For now, unfortunately, I don’t have more time to dedicate to it, but it’s probably possible to get it running with OpenJDK with some modifications (or provide a Docker image with these changes).
