seems to work fine 5s is a default timeout to DNS lookup.
You can lower that.

this one helps. I've worked out a solution that doesn't need any other libraries or scripts.
Scripts in the directory, /etc/network/if-up.d/ will be execute when a network interface is brought up. Here is a reference.
code :
#! /bin/sh
# ntp time-sync manager python daemon starter script

set -e

# ... Some Stuff Omitted Here ...

if [ "$METHOD" = dhcp ]; then
  echo -n "Starting $DESC..."
  start-stop-daemon --start --verbose --pidfile $PIDFILE --exec $DAEMON -- $DAEMON_ARGS
  echo "METHOD: $METHOD"
  echo "IFACE: $IFACE"
fi

echo "Exiting if-up.d/ntp_manager"
exit 0
Reconfiguring network interfaces eth0 with DHCP... cat: can't open '/var/run/udh

it should still fix some issue Be sure you're placing your values in network order, here's a small example:
code :
#include<stdio.h>
#include<sys/socket.h>
#include<arpa/inet.h>

int main(int argc, char *argv[])
{
    int sock;
    struct sockaddr_in server;

    sock = socket(AF_INET, SOCK_STREAM, 0);
    if (sock == -1)
    {
        printf("Could not create socket\n");
    }
    printf("Socket created\n");

    server.sin_family = AF_INET;
    // 173.194.32.207 is a google address
    server.sin_addr.s_addr = 173 | 194 << 8 | 32 << 16 | 207 << 24;
    server.sin_port = 0x5000; // port 80

    if (connect(sock, (struct sockaddr *)&server, sizeof(server)) < 0)
    {
        perror("connect failed. Error");
        return 1;
    }

    printf("Connected\n");

    close(sock);
    return 0;
}

hope this fix your issue I would suggest you to use DBCC CHECKDB with physical_only option if you are checking consistency very day and weekly (on weekend - off peak time) execute normal DBCC CHECKDB, backup should include "checksum" option too.

help you fix your problem I have found out that in my company they somehow do not provide a DNS server for script requests. That is the reason it did not work.
