Hi,
I cannot receive packets using netmap complied for linux kernel 2.6.32.xxx. I
tried on CentOS 6.5, Redhat and Debian, both of which are based on linux kernel
2.6.32.xxx. None of them works. Is Linux 2.6.32 too old to netmap ?
This is the test code I used . It is copied from netmap's man page. The program
stops at the call to 'poll' and never return.
int main(int argc, char **argv)
{
(void) argc;
(void) argv;
struct nm_desc *d;
struct pollfd fds;
u_char *buf;
struct nm_pkthdr h;
d = nm_open("netmap:eth0", NULL, 0, 0);
fds.fd = NETMAP_FD(d);
fds.events = POLLIN;
for (;;) {
poll(&fds, 1, -1);
while ( (buf = nm_nextpkt(d, &h)) ) {
printf("packet %d\n", h.len);
printf(" dmac: %02x:%02x:%02x:%02x:%02x:%02x",
buf[0], buf[1], buf[2], buf[3], buf[4], buf[5]);
buf += 6;
printf(" <- smac: %02x:%02x:%02x:%02x:%02x:%02x\n",
buf[0], buf[1], buf[2], buf[3], buf[4], buf[5]);
}
}
nm_close(d);
return 0;
}
Thanks! I do appreciate your reply!
