No

once the remote monitor is activated, it cannot be deactivated anymore. at least on windows, might work on linux?

  • do something like ncat localhost 6510 in the shell
  • avtivate remote monitor in GUI
  • press alt-h, remote monitor works
  • deactivate remote monitor in GUI
  • press alt-h. we still get the remote (? we should not?)
  • now terminate the the ncat connection

VICE now goes mad.... fast blinking cursor, constantly spitting out Error - vice_network_send: internal error (ret:-1 buffer_length:10 errno:9 - Bad file descriptor) in the log

    mmmh with telnet it works... what package has the "ncat" command you are using?

    indeed telnet works... i also tested 2 other ncat versions, and one of them also works, the one from msys2 itself gnu-netcat-0.7.1-2-x86_64.pkg.tar.zst

    so i guess this can be closed...

    would still be interesting to be able to reproduce... such funky behaviour should never happen :)

    one that does the funky thing i got from here: https://nmap.org/dist/

    really strange. the emulator runs at 100%, but the cursor blinks almost twice as fast.

      Which one exactly?

    mmmh also please tell exactly what cmd you are using with this ncat - it does not appear to work for me at all shrug

    i used the one at the bottom, ncat-portable-5.59BETA1.zip
    yes, i get it's ancient, but this is the one that runs just out of the box.

    and it doesn't matter, the same happens if i extract a new one from the https://nmap.org/dist/nmap-7.95-setup.exe package. it only has a ton of dependencies.

    ncat localhost 6510

    but right now i figured out, the funny stuff only happens if i press x in the "monitor shell" and then terminate ncta using CTR-C. it does NOT happen if i press CTR-C right after some monitor command. interesting.

    this nc does the same:

    https://eternallybored.org/misc/netcat/

    but it is windows only. it looks like the connection isn't closed properly. strangely it only happens after "closing" the monitor using x and then killing nc

    so... no idea if this is a VICE issue or nc
