I have been creating a simple socket client program and everything seems to go well until it calls the function gethostbyname(). I have compiled and executed the same program under Debian and RedHat and it DOES work while it does NOT under Gentoo. I have tried it in 3 different (different users, different configuration) Gentoo systems and no way. I include a small code that shows up what I told you. Reproducible: Always Steps to Reproduce: ]#include <stdio.h> #include <sys/types.h> #include <sys/socket.h> #include <netinet/in.h> #include <netdb.h> #define MAXDATASIZE 100 #define MAXHOSTLEN 64 int main(int argc, char **argv) { int error; int fd, numbytes; char buf[MAXDATASIZE]; struct hostent *he; struct sockaddr_in server; char * anfitrion; int puerto; anfitrion = (char *) malloc (sizeof(char)*63); if (argc !=3) { printf("Uso: %s <Direcci
