![]() Use -image and -tcpdump-image flags (or KUBECTL_PLUGINS_LOCAL_FLAG_IMAGE and KUBECTL_PLUGINS_LOCAL_FLAG_TCPDUMP_IMAGE environment variables) to override the default container images and use your own e. if specified, ksniff will use the specified path as the remote path to upload static tcpdump to. ![]() if specified, ksniff will use this path as the local path of the static tcpdump binary. if specified, ksniff will redirect tcpdump output to local file instead of wireshark. specify a specific tcpdump capture filter. I found no way to filter the traffic to a time range. If omitted, all Pod interfaces will be captured.ĬAPTURE_FILTER: Optional. I look at it with wireshark The customer tells: Please look at the traffic at 8 o'clock. If omitted, the first container in the pod will be chosen. It indicates the communication’s port number. The source and destination IP addresses are translated to dotted code format by Wireshark and tcpdump. It displays the communication’s port number. ![]() used to specify the target namespace to operate on.ĬONTAINER_NAME: Optional. Both Wireshark and tcpdump use dotted code to translate the source and destination IP addresses. To start tcpdump and Wireshark only a single one-liner is needed. Sometimes the easiest solution is to use tcpdump to capture traffic on the remote server, and then run Wireshark to take a look at it. Unless you have professional networking equipment, it’s hard to analyze traffic that doesn’t involve your computer. the name of the kubernetes pod to start capture it's traffic. Wireshark is a powerful tool, but it has its limitations.
