Lanc Ip Snffer For Mac

I wrote a http sniffer program, first ran it in my standalone pc, and it worked well. And when i tried this in a LAN setting, and set the eth0 to promisc mode, the program captures only the URLs browsed by the system in which it is running, but not the ones browsed in neighbouring systems. Am i missing something here.

I've heard people talk about ' setting up subnets ', ' use routers / additional ethernet cards ' etc, but i dont really understand / know how to do / or even if i should be doing anything of that sort. Perhaps you are trying to make a sort of ethernet sniffer to capture other's computer traffic? It may or may not work, depending on the network to which you are connected. If you are connected to a reasonably smart ethernet switch, you will probably see only you pc's packets, broadcast packets (but they are not http.) and not much else. You must at least configure the ethernet switches so you port receives all the traffic.

If you system administrator let you do it. Or maybe I am completely misunderstanding the question (sorry).

If you have more than one workstation, you administer several machines connected to a network, or just frequently connect to various networks, sooner or later you’ll find a packet sniffer to be quite useful. New users may be asking themselves why would they need such a tool so here are a few things it allows you to do:.

Analyze network problems. Identify suspect content. See what other users are doing. There are many tools up for the job that work on Mac OS X but if you’re looking for a free packet sniffer, Packet Peeper is an open source project that does the job quite well. Nowadays it’s very common to be in the local coffee shop, connected to an open wireless network while having a hot cup of java.

If you fire up Packet Peeper and opt for promiscuous capture mode, you can see not just your packets, but also those addressed to the rest of the coffee drinking surfers. As you can see from the screenshot above, Packet Peeper’s interface is very simple and easy to use. Watching how this tool captures your network traffic will make you think twice at what you do the next time you’re connected to one of those free hotspots. After all, you may not be the only one with such a tool. For example, if you check your POP e-mail account that sends the username and password in plain text to the server you’ll see that Packet Peeper has captured them both: Captured traffic can be saved for later analysis. This is particularly useful if you have to analyze traffic from several networks at once and want to do it later, after all the capturing has been done. If you want details, you can get plenty.

The image above shows what a TCP stream looks like. Analyzing a packet is easy when you have enough room.

The image above depicts the viewing of a packet in a separate window. It has been scaled to fit into this page but, as you can see, it can be expanded to give you more info on the same screen. As options go, there are several that can be setup before a capture session is initiated. As you get more into packet sniffing, you’ll find them quite useful. Packet Peeper is available for download, take it for a spin.
