![]() ![]() But a HTTP proxy like Fiddler is a reasonable workaround. On the whole, I'd prefer to stick with a sniffer for localhost debugging. For example, with Fiddler you can set breakpoints and tamper with the HTTP data before it is sent or received. I'm using Fiddler as a localhost sniffer that's limited to the HTTP protocol, but it does have some capabilities beyond what you'd see in a sniffer. ![]() ![]() Wireshark lets you analyze gRPC messages that are transferred over the network, and learn about the binary format of these messages. How does Wireshark capture WiFi traffic Capturing Packets with Wireshark Click View > Wireless Toolbar. Step 4: Launch Wireshark and Start Capturing. Step 3: Configure Wi-Fi Sniffing Channel. There's tons of supporting documentation on how to use it, including two MSDN articles. Wireshark is an open source network protocol analyzer that can be used for protocol development, network troubleshooting, and education. First, enter into superuser mode otherwise, we will get permission to do this. I had some erratic results under IE7, but Fiddler basically works as advertised. What's a poor developer to do? The only recourse is a local HTTP proxy, such as Fiddler:įiddler has some special integration with IE that makes it particularly easy to use, but it can be used with Firefox as well. Localhost packets don't pass through the regular network stack, so they're invisible to an ethernet sniffer. However, Windows ethernet sniffers do have one significant limitation: they can't sniff localhost traffic. Ethernet sniffers should be a standard tool in your development troubleshooting toolkit, too. I frequently use sniffers to troubleshoot servers and desktops alike. Installing a sniffer, even after installing the required WinPcap packet capture library, doesn't require a reboot. I've had great success using ethernet sniffers (such as Etherdetect, or Ethereal) to troubleshoot communication problems. ![]()
