The mdns source ip command has three functions when the device works as an mDNS gateway: When the mDNS gateway is enabled to periodically discover services, it encapsulates the configured source IP address into outgoing mDNS query packets so that it can receive response packets from service provisioning devices. The flag field consists of four bits. A MikroTik router with DNS feature enabled can be set as a DNS server for any DNS-compliant client. The library API that dns-sd uses is documented in /usr/include/dns_sd. The requirements are driven by the Zeroconf working group; the implementation details are a chartered work item for the DNSEXT group. When parsing mDNS packets, a memory space is freed twice if an invalid query name is encountered, leading to arbitrary code execution in the context of the mdnscap process. mDNS When you utilize a discovery or configuration tool, it is unable to locate your device connected to the same network When you utilize a discovery or configuration tool, it randomly finds devices which also disappear randomly. ipconfig is used to display and modify IP configuration settings used by your local, like refreshing DHCP.

Browse for mDNS/DNS-SD network services and browsing domains using the Avahi daemon. When the remote requests are enabled, the MikroTik router responds to TCP and UDP DNS requests on port 53. As such, although port 5353 is assigned to Multicast DNS (MDNS), there is no *guarantee* that a packet sent to or from port 5353 is a MDNS packet. Using a similar concept, the mDNS attack script created by malicious actors sends a specialized unicast query for eliciting a response from mDNS devices. The requirements are driven by the Zeroconf working group; the implementation details are a chartered work item for the DNSEXT group. + Added SRV query handling to DNS spoof + New mDNS spoof plugin + New low level decoders + New decoder for ip over pppoe + Added PPP DLT to interfaces + Add experimental Lua support to Ettercap + New Bundle libnet and curl + Full support for wifi decrypting (wep and wpa) Removed - Disabled update feature (not working anymore and not secure).
