Putting it all together we get the following command: The '-s' flag is used to specify how many bytes to display (where '-s 0' means to not truncate the message body at all). The '-A' flag tells tcpdump to print each packet in ASCII, exposing the HTTP headers and message body. It is often useful to see the contents of the packets as well. This information can be valueable because it shows the order that packets were sent and received. ('All events on your calendar:') įor each packet that matches the filter expression, tcpdump will display a timestamp, the source and destination of the packet, and several TCP flags. Using the Google Calendar documentation as a reference, I can retrieve and display calendar events like this, where PUBLIC_FEED_URL holds the event feed URL.ĬalendarService myService = new CalendarService('exampleCo-fiddlerExample-1') ĬalendarEventFeed resultFeed = myService.getFeed(feedUrl, CalendarEventFeed.class) ( Editor's Note: as of v3, Google Calendar API no longer uses the Google Data format.) The first thing to do is to get the calendar's event feed URL by clicking on the button on the calendar settings page: The Google Calendar API documentation has information about how to use the RESTful Google Data API to interact with my calendar programmatically. I also want to send out a newsletter with upcoming events, so rather than copying the information from the Google Calendar website, I can use the Google Calendar data API to query this calendar and retrieve events. I've made this calendar public so team members and other riders can view the calendar and participate in the events. I'm putting together a cycling team for a charity ride, and have created a calendar for events such as info sessions, team fundraisers, and training rides.

Examining the contents of these packets and the order in which they were sent and received can be a useful debugging technique. Commonly called 'packet sniffers,' these tools capture all network packets that move across your network interface.

This article introduces several tools that can help make the data on the wire more visible and useful. Some of the most difficult bugs to track down are caused by a disconnect between what we think we're sending to the server, and what is actually going across the wire. A common source of frustration is not knowing exactly what message was sent to the server, or what response was received. Developing applications that interact with web services poses a unique set of problems.
