[RESOLVED] Accept errors

[Bear35805]

I am trying to write a Linux Daemon that will accept TCP/IP connections on a specific port. During development I did not have the code in that creates a child process and then exits the parent and everything worked fine. I was able to run a test for 24 hours without a problem.

However, after putting the code at the beginning that initiates a child process, then exits the Parent the Accept function started to fail. Below is my accept function.

if((new_sock = accept(sock, (struct sockaddr*) &client_name, &size)) < 0){
syslog(LOG_MAKEPRI(LOG_LOCAL1, LOG_ERR), "Error accepting connection");
}

When I run it and the connecting device attempts to connect, the Syslog starts to fill up with the above message if it is running as a child process.

If this is not the proper forum for this question, please forgive me and point me to the correct forum.

OK, so what's your question?

The question is why does the accept return a value less than zero when it is running as a Daemon? In other words this code is in the child process that continues running when the main process has exited. If I remove the code that starts the Child Process and exits the parent, the accept works just fine. How can I make it work properly under the Child Process?

I have attached the CPP file that contains the code.

You should read the documentation of accept()
It it fails, it will set the errno variable to show why it failed.

Thanks JnMacd that got me going in the right direction to fix the problem.
