Thank you. I want to bind with the bind(2) function in C. How do I supply
the interface here or what function do I need to call instead?

#include <arpa/inet.h>

int main(int argc, char *argv[])
{
int s;
struct sockaddr_in6 ip6;
// Basic inet6 socket
s = socket(AF_INET6, SOCK_DGRAM, 0);
// Initialize the ip6 struct
ip6.sin6_family=AF_INET6;
ip6.sin6_addr=in6addr_any;
ip6.sin6_port=htons(1234);
ip6.sin6_scope_id=if_nametoindex("ippusbxd");
inet_pton(AF_INET6, "fe80::3004:2dff:feb6:b5c7", (void
*)&ip6.sin6_addr.s6_addr);
// Bind
bind(s, (struct sockaddr *)&ip6, sizeof(struct sockaddr_in6));
}
This works now (had to add the
"ip6.sin6_scope_id=if_nametoindex("ippusbxd");"). So ippusbxd is running
now mirroring the printer onto fe80::e828:7eff:fe19:9962, port 60000 on
the ippusbxd interface.
This would especially mean that I can access the printer's web admin
interface by pointing a browser to this address so I try the simple
command line browser wget:
