Hi all,
I am trying to modify the ISC DHCP client code to support DHCP for
ethernet virtual interfaces....
When I run dhclient eth0:0, I get the error
Bind socket to interface: No such device
I figure thats because of this part of the client code
----------------------------------------------------------------------------
if ((sock = socket(PF_PACKET, SOCK_PACKET,
htons((short)ETH_P_ALL))) <0) {
report_error();
}
/* Bind to the interface name */
struct sockaddr sa;
memset (&sa, 0, sizeof sa);
sa.sa_family = AF_PACKET;
strncpy (sa.sa_data, (const char *)info -> ifp, sizeof sa.sa_data);
//info->ifp is of type struct ifreq
if (bind (sock, &sa, sizeof sa)) {
report_error("bind"); <----- this is the error
}
----------------------------------------------------------------------------
Could someone help me with this ?
Thanks,
Subhash
