inet_ntoa and segmentation fault

[Shachar Shemesh]

Today was the second time that I ran across this problem. Each time I 
run across it, I search Google, come back empty handed, and then have a 
second look, find the solution, and altogether waste too much time on a 
problem I have solved before. As a measure to prevent this, I am posting 
both problem and solution to this mailing list, that has a high Google 
juice, so that the next time, I will find my own solution.

In other words, I am shamelessly using the list to archive my problems 
and solutions.

The problem:
The following code segfaults:
    printf("%s\n", inet_ntoa(addr) );

The cause: Failing to include the relevant header file.

The solution: Add:
#include <arpa/inet.h>

Sorry for the noise.
