unable to set ipv6 interface name using ioctl

nikole · 11-09-2011, 09:09 PM

i am trying to create a virtual ip on eth0. but the new interface created is with same name as eth0, instead of eth0:1.

i tried something like this

socv6=socket(AF_INET6, SOCK_DGRAM, 0);

strcpy(ifr.ifr_name,"eth0:1");

ioctl(socv6, SIOGIFINDEX, &ifr);

ifr6.ifr6_ifindex = ifr.ifr_ifindex;

ifr6.ifr6_prefixlen = 64;

ipv6add= (struct in6_addr *)&ifr.ifr_addr;

inet_pton(AF_INET6, "fe80::19", &ifr6.ifr6_addr);

ioctl(socv6,SIOCSIFADDR,&ifr6);
