Error when setting subject key id The request is invalid

[Cale]

mvoice compiled successfully on Ubuntu 22.04 after building OpenDHT from source.

When running mvoice I receive an error:

❯ bin/mvoice https://dvref.com/mrefd/json/?format=json copied to .config/mvoice/m17refl.json .config/mvoice/mvoice.cfg was not found! terminate called after throwing an instance of 'dht::crypto::CryptoException' what(): Error when setting subject key id The request is invalid. Aborted (core dumped)

I touched a blank config file which allowed the 'not found' message to go away.

The error seems to be centered around OpenDHT, but that's as far as I'm able to go with it.

Thanks for any pointers.

Sorry, try as I might, I can't reproduce this. I believe you are crashing on line #315 of MainWindow.cpp, where your dht identity is created and used to start your dht node. Your callsign isn't configured yet, but the call to dht::crypto::generateIdentity() should still work even if you callsign string is empty.

Do you know how to use gdb? You'll have to set DEBUG to true in your mvoice.mk file, clean and re-make mvoice and then launch it with "gdb mvoice" and then "run". When it crashes, you'll get a prompt from gdb. Then do a "bt" and send me the output, and we'll go from there.

Thanks Tom. Here's the debug output:

Well, that wasn't very helpful. Let's make sure you're not using the old package try:

apt list libopendht-dev

[Cale]

Sorry, was out of town and away from the laptop for a couple days. Here's the version:

libopendht-dev/jammy 2.3.1-1build3 amd64

[n7tae]

Sorry to put you through these hoops...

In an empty directory, can you please create dhttest.cpp containing:

#include <iostream>
#include <opendht.h>
#include <thread>
#include <string>

int main()
{
    dht::DhtRunner node;
    std::string s;
    //s.assign("mynode");
    node.run(17171, dht::crypto::generateIdentity(s), true, 59973);
    std::cout << "node is running\n";
    std::string bs("xrf587.openquad.net");
    node.bootstrap(bs);
    std::cout << "Bootstrap from " << bs << std::endl;
    std::this_thread::sleep_for(std::chrono::seconds(5));
    node.join();
    std::cout << "node is not running\n";
    return 0;
}

Then compile it: g++ -std=c++17 -o dhttest dhttest.cpp -lopendht -pthread

And run it: ./dhttest

If it crashes, uncomment the s.assign line (remove the //) and compile it and run it again.

Let me know what happens.

[Cale]

No worries at all. I just hope this helps others and isn't an edge-case because of something dumb on my machine.

It did crash initially, but uncommenting the requested line allowed it to run:

❯ ./dhttest 
terminate called after throwing an instance of 'dht::crypto::CryptoException'
  what():  Error when setting subject key id The request is invalid.
Aborted (core dumped)

❯ ./dhttest 
node is running
Bootstrap from xrf587.openquad.net
node is not running

Thank you! I have pushed up a fix to mvoice that should work for you, mvoice version 1.1.4. I am going to close this issue. If you're still having problems, you can reopen it, or open a new issue.

[Cale]

Thanks, Tom. I pulled the latest and was able to compile, run, and connect. I appreciate the assistance!
