Redhat 5.2 a gethosbyaddr

[Juraj Kovac]

Caute.
Co poviete na nasledujuci problem?

# include <netdb.h>
# include <sys/socket.h>
# include <errno.h>

main(int argc, char *argv[])
{
struct hostent *hp;

hp = gethostbyaddr(argv[1], 16, AF_INET);
if (hp) printf ("%s\n", hp->h_name);
else perror("gethostbyaddr");
}

ked to spustim, tak mi to vypise:
gethostbyaddr: Address family not supported by protocol

Tak som z toho magor, ved som tam uviedol type AF_INET, iny to ani
nepodporuje podla man gethostbyaddr.
Mam nejak zle nakonfigurovany resolver?
