First, you can analyze the information in real time. Streaming your packet capture to Wireshark can be very valuable for three main reasons. Streaming the Packet Capture to Wireshark Once the file is saved to the Files menu, it can be download by dropping and dragging through Winbox, downloading from the router’s webpage, FTP, or any other means you would normally use. Using the Filters will make the packet capture easy to understand. The Only Headers option and the Memory Scroll option should also be evaluated for their use. To save your packet capture to your router, all that is required is to give the file a name and ensure that the File Limit size makes sense for what you are trying do. First, we’ll look at the settings, then we’ll look at how to save the packet capture to the router, and finally, we’ll look at streaming the packet capture to a PC running Wireshark. This tutorial will only cover the Packet Sniffer tool found under the main Tools menu. There is the Wireless Sniffer specifically for wireless packets and then there is the firewall (mangle has the ability to sniff packets). There is the Packet Sniffer tool that is used for everything except wireless packets. RouterOS includes three different ways ( 4 if you include CALEA) that you can capture packets. Plain passwords on the command line are a security risk.Packet Captures are one of the best and primary troubleshooting tools in networking. $ ssh 'echo | sudo -S tcpdump -U -s0 not port 22' -i eth0 -w - | sudo wireshark -k -i. You can check and find the proper one via $ ip link. It depends on its type and count off different interfaces. And the network interface (eth0) in not necessarily eth0. Port is automatically chosen by protocol specification, so not necessarily required. Replace content in angle brackets to your needs. This enables root privileges for tcpdump on the host to be sniffed remotely. If you have no root access via ssh on your host being sniffed to, like on a raspberrypi, and for good reason you don't want to enable it or you simply can't do it, for whatever reason, there is a slightly different approach of (alternative to answer to that from we do here is to pipe the sudo password into the sudo command which executes its argument tcpdump.
