Compileaza dracia urmatoare pe alta masina si dupa aia copiaza-l acolo
si incearca-l (vezi ca e scris in dur in el ifname "eth0").
Nu l-am facut eu ca mi-a fost lene, am luat un exemplu de pe internet
(stiam ce sa caut).La mine merge :).
asa arata ldd pe binar la mine (probabil se poate face si static :) )
linux-gate.so.1 => (0x0093c000)
libc.so.6 => /lib/libc.so.6 (0x0095b000)
/lib/ld-linux.so.2 (0x0093d000)

return(-1);
}
strcpy(ifr.ifr_name, "eth0");
sin->sin_family = AF_INET;
if(ioctl(sockfd, SIOCGIFADDR, &ifr) == 0)

printf("%s",inet_ntoa(sin->sin_addr));
}
return 0;
}
