Running Server issues

[karanmankar95]

Hi, I am trying to implement QUIC into my system for a college project. I am using Ubuntu Desktop and I am able to successfully run examples/client. However while trying to run examples/server I am getting the following output.

root@DESKTOP-N0VT1DM:/home/kmm1110/ngtcp2/examples# ./server 0.0.0.0 9090 privatekey certificate.crt Using document root /home/kmm1110/ngtcp2/examples/ root@DESKTOP-N0VT1DM:/home/kmm1110/ngtcp2/examples#

Any help would be massively helpful. Thank you

Hello there, I am also having the same problem detailed above. I am running Ubuntu Desktop and only able to run examples/client. When I attempt to run examples/server the code fails to execute (Same output as you are getting). I have been attempting to solve this with no progress. Any help on this matter would be extremely helpful, thank you!

I had the same issue. it was : if (setsockopt(fd, SOL_SOCKET, SO_REUSEADDR, &val, static_cast< socklen_t >(sizeof(val))) == -1) that fails without writing any error but by commenting it, I can run it with no pb on my Ubuntu (WSL)

Hey guys, I am not able to send or receive a file using the commands given in the readme. I am using ```/examples/client SERVER_IP PORT -d DATA_FILE. Am I missing something in the commands that is not allowing data to go through? The headers are sent through and handshake is done but data file is not sent.

@karanmankar95 By running ./client --help in ~/ngtcp2/examples$ you can see that

Usage: client [OPTIONS] <HOST> <PORT> [<URI>...]

So in your case you should run /examples/client -d PATH_TO_FILE SERVER_IP PORT .

However, I also tried something similar: SERVER: ~/ngtcp2/examples$ ./server --htdocs /home/valdas/ngtcp2/examples/servers_folder/ 127.0.0.1 7777 server.key server.cert

CLIENT: ~/ngtcp2/examples$ ./client --data /home/valdas/ngtcp2/examples/clients_folder/MrClient.txt 127.0.0.1 7777

But I couldn't see neither contents of the file, for the name being transferred via Wireshark. In particular, I looked at the two HTTP3 packets and their HTTP3 information is more than boring:

What would be the easiest way to send some simple human-readable messages (e.g. "Hello world")?
