I'm trying to duplicate a close_wait issue on RHEL and found two parts of a sample on this site, but I lack the skill to get it working.

The second part is where I tried to add a main and compile, but it fails. I'm not even sure that's how it was intended to run but I don't see a function call in the first part so I assumed I need a "client" and a "server" binary.

Am hoping to get advice on how to make these pieces run.

This is the first part and it compiles OK.
Code:
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <errno.h>
#include <string.h>
#include <syslog.h>
int main()
{
        int sock, connected, bytes_recieved , true = 1;
        char recv_data[254];
        struct sockaddr_in server_addr,client_addr;
        int sin_size;
        //FILE *f;
 
        if ((sock = socket(AF_INET, SOCK_STREAM, 0)) == -1) {
            perror("Socket");
            exit(1);
        }
        if (setsockopt(sock,SOL_SOCKET,SO_REUSEADDR,&true,sizeof(int)) == -1) {
            perror("Setsockopt");
            exit(1);
        }
        server_addr.sin_family = AF_INET;
        server_addr.sin_port = htons(5000);
        server_addr.sin_addr.s_addr = INADDR_ANY;
        bzero(&(server_addr.sin_zero),8);
        if (bind(sock, (struct sockaddr *)&server_addr, sizeof(struct sockaddr)) == -1) {
            perror("Unable to bind");
            exit(1);
        }
        if (listen(sock, 5) == -1) {
            perror("Listen");
            exit(1);
        }
        fflush(stdout);
 
        while(1)
        {
            sin_size = sizeof(struct sockaddr_in);
            connected = accept(sock, (struct sockaddr *)&client_addr,&sin_size);
            //f = fopen("/var/log/keys.log","w");
            //printf("received conn");
            while(bytes_recieved = recv(connected, recv_data,254,0))
            {

              recv_data[bytes_recieved] = '\0';

                //printf("%s", recv_data);

              openlog("keys", LOG_PID, LOG_AUTHPRIV);
              syslog(LOG_INFO, "%s", recv_data);

              fflush(stdout);
              close(sock);
            }
        }
      //fclose(f);
        return 0;
}
Part 2.
Code:
int sck_log(char *message) {

        int sock;

        char send_data[254];

        struct hostent *host;

        struct sockaddr_in server_addr;
        host = gethostbyname("10.25.14.110");
        if ((sock = socket(AF_INET, SOCK_STREAM, 0)) == -1) {
            perror("Socket");
            exit(1);
        }
        server_addr.sin_family = AF_INET;

        server_addr.sin_port = htons(LOG_PORT);
        server_addr.sin_addr = *((struct in_addr *)host->h_addr);
        bzero(&(server_addr.sin_zero),8);
        if (connect(sock, (struct sockaddr *)&server_addr,
                    sizeof(struct sockaddr)) == -1)
        {
            syslog(LOG_INFO, "Unable to start socket");
            exit(1);
        }
        else
        {
            send(sock,message,strlen(message),0);
            return 0;
        }

        return 0;

}
