--- Comment #5 from Aravinda VK <avishwan at redhat.com> ---
I think it is failing while doing strcmp comparison.

```
            if (!strcmp(firstip, nextip)) {
                return GF_AI_COMPARE_MATCH;
            }
```

Wrote a small script to compare the hostnames

```
#include <stdio.h>
#include <string.h>

int main()
{
    char* first = "roger-1812-we-01";
    char* second = "roger-1903-we-01";
    char* third = "roger-1812-cwes-01";
    printf("First(%s)  vs Second(%s): %d\n", first, second, strcmp(first,
second));
    printf("First(%s)  vs Third(%s): %d\n", first, third, strcmp(first,
third));
    printf("Second(%s) vs Third(%s): %d\n", second, third, strcmp(second,
third));
}

```

And the output is


First(roger-1812-we-01)  vs Second(roger-1903-we-01): -1
First(roger-1812-we-01)  vs Third(roger-1812-cwes-01): 20
Second(roger-1903-we-01) vs Third(roger-1812-cwes-01): 1


We should change the comparison to 

```
if (strcmp(firstip, nextip) == 0) {
    return GF_AI_COMPARE_MATCH;
}
```
