I am booting a Netboot Image with a MacMini 5.1, after the system is up a shell script calls a server via curl.
At the moment the Internet connection is up and running. I verify that doing a ping to the same server before using curl.
Every now and then it is not working properly. When it is not working the http get request never reaches the server. Since the ping worked before i think it might be a DNS problem.
If i use curl "manually" 2 time working 3rd time not... Its not easy to reproduce this error...
So i tried to add the IP to /etc/hosts and it is still not working properly every time.
What might cause this problem ?
