Time to put on my grumpy hat and type a nastygram. I fixed my problem, but discovered that the stinking service is sending authentication credentials in plain text, through an unencrypted channel. Then start up WireShark, and simply capture all traffic on UDP port 37008 with the following filter: udp port 37008Īnd that’s it. tool sniffer set streaming-enabled=yes streaming-server=ip.of.wireshark.box You can of course also use the Tools->Packet Sniffer tool in the GUI. On the Mikrotik, the following commands, adding your computer’s IP as the streaming server. In terms of TCPs behavior with an MTU less than 1500, it will adapt to avoid fragmentation by reducing the size of its segments. This will give you insight into any issues that may be occurring. Mikrotik’s RouterOS provides a great sniffing tool, where you can send a copy any traffic on the net to a different computer. Regarding measuring fragmentation, errors, and retransmissions, you can use a tool like Wireshark to capture and analyze network traffic. Being a man in the middle is a pain as I need to set up proxies to route traffic through my network.Įnter the wonders of adding a Mikrotik router into the mix, and life is bliss! While I’ve used WireShark in the past, it’s generally debugging traffic to or from my computer. IP address: ip.addr=192.168.0.1, 8.8.8.8, etc.I’ve been debugging a frustrating issue with a remote server rejecting some credentials from a Raspberry Pi based system on my network. Since the router/switch is forwarding packets constantly, we may need to apply some display filter to filter out the packets we are interested in. Run Wireshark, select the interface you connect to SMB router or switch.Input the IP address to the address bar in the web browser and you will visit the GUI of the SMB switch.Īfter logging into the page, go to MAINTENANCE-Mirroring, click Edit, select the port connecting to your PC in Destination Port Config and enable Ingress and Egress option in the port you want to capture packets in Source Interface Config, click Apply. Input the IP address to the address bar in the web browser and you will visit the GUI of the SMB router.Īfter logging into the page, go to Network-Switch-Mirror, enable Port Mirror, select the port connecting to your PC in the Mirroring Port and the port you want to capture packets in the Mirrored Port, click Save. Set Port Mirror for PC and the port you want to capture packets.Connect PC to the SMB router or switch directly.Download and install Wireshark on your PC.Note: Connect PC to SMB router or switch directly.
It’s a free and powerful sniffing and analyzing software. This document will introduce how to capture packets using Wireshark in SMB router or switch. Packets capture and analysis are very important for us to troubleshoot when some problems occur such as the router can’t obtain IP from ISP, the client can’t receive multicast packets, etc.
