How to run on linux

[duramato]

I'm trying to run this on linux, but I'm not being able to, either via lua or via wine.

[ivan386]

Open command line in lua-dht directory and run command:
wine start ./start.cmd

[duramato]

That shows `

# wine start ./start.cmd
~/lua-dht# err:winediag:nulldrv_CreateWindow Application tried to create a window, but no driver could be loaded.
err:winediag:nulldrv_CreateWindow Make sure that your X server is running and that $DISPLAY is set correctly.

If I try to run lua directly from wine it throws an error:

# wine lua5.1.exe lua/dht.lua > msgs.txt
Z:\root\lua-dht\lua5.1.exe: lua/dht.lua:834: attempt to call global 'on_error' (a nil value)
stack traceback:
        lua/dht.lua:834: in main chunk
        [C]: ?

On first command lua show error but programm is run. Second command fail because port is already assigned.

Need to stop lua first and try second command.

I just ended up creating a docker container to sort any issues with ports, which seems to have worked.

Here's the dockerfile should anyone want it.

FROM i386/ubuntu:latest

RUN dpkg --add-architecture i386 && \
    apt-get update && \
    apt-get install -y xvfb wine32 git make gcc g++ lua5.3 lua5.3-dev && \
    apt-get clean && \
    rm -rf /var/lib/apt/lists/*

RUN git clone https://github.com/ivan386/lua-dht.git \
    && cd lua-dht

WORKDIR /lua-dht

RUN sed -i 's|bind.\"127.0.0.1\"|bind\("0.0.0.0"|g' lua/dht.lua

EXPOSE 6543

CMD ["wine", "lua5.1.exe", "lua/dht.lua"]

On another note, it seems that sometimes it just hangs with no aparent reason, as there's nothing extraordinary on the logging. Have you ever experienced something like this?

Here's a relevant snippet of the logging before it hangs: https://gist.github.com/duramato/a8fe100f67b4ea9f11c2c9181696863b

It seems to crash when there's a large ammout of peers, altough I can't be sure. The logs don't seem to mention anything relevant except for the traceback.

Here's the traceback from dht_error.log:

Z:\lua-dht\lua\compact_encoding.lua:40: bad argument #1 to 'mod' (number expected, got nil)
stack traceback:
