Cannot connect to honeyd from same machine

[DataSoft]

If you try running honeyd on a network, packets going to any of the VMs are lost if they're sent from the host computer. The effect is that the host that is running honeyd is unable to contact any of the VMs created.

This actually appears intentional. Not sure as to why, though. Look at the following snippets:

In honeyd_recv_cb() of honeyd.c

    /* Ignore our own packets */
    addr_pack(&eth_sha, ADDR_TYPE_ETH, ETH_ADDR_BITS,
        &eth->eth_src, ETH_ADDR_LEN);
    if ((req = arp_find(&eth_sha)) != NULL &&
        (req->flags & ARP_INTERNAL))
        return;

And then a few lines later:

/* Check our own address */
addr_pack(&addr, ADDR_TYPE_IP, IP_ADDR_BITS, &ip->ip_dst, IP_ADDR_LEN);
if (addr_cmp(&addr, &inter->if_ent.intf_addr) == 0) {
    /* Only accept packets for own address if they are GRE */
    if (!router_used || ip->ip_p != IP_PROTO_GRE)
        return;
}

And no, merely commenting these lines out doesn't solve the issue.

If honeyd is ignoring them like that but it still doesn't work my guess is the problem lies in replying to the packets and ignoring them just saves cycles.

This isn't really a bug, it's intended behavior of Honeyd. Closing.
