Expert Network Analysis An online tool where you can upload a pcap traffic trace captured in the network point considered as problematic and receive a personalized report.

These tools will either generate traffic and transmit it, retransmit traffic from a capture file, perhaps with changes, or permit you to edit traffic in a capture file and retransmit it. Cat Karat - Easy packet generation tool that allows to build custom packets for firewall or target testing and has integrated scripting ability for automated testing.

Colasoft Packet Builder includes a very powerful editing feature. Besides common HEX editing raw data, it features a Decoding Editor allowing users to edit specific protocol field values much easier. ProConvert convert capture files between different formats - some that Wireshark currently doesn't support closed source freeware, unsupported and noted as buggy by vendor, registration and WildPackets maintenance contract required, Win32 only.

Provides a Web-Based frontend to the dumpcap network packet capture engine with dump file format: pcapng support. Simultaneous network packet capture on up to 4 network interfaces per Multi-Tap session is supported. Capture starting can be delayed by a duration or an absolute date.

Ethernet traffic from that USB device if the platform supports it which it usually will do. On Win32 you can however try:. C5 SIGMA flattens the Wireshark protocol tree into a relational table structure useful for intrusion analysis and data correlation with other systems.

It also enables SQL queries against otherwise unnamed text fields visible in the Wireshark protocol tree by intelligently generating human readable names.

The bittwiste tool from Bit-Twist. The Crypto-PAn tool. The Network Expect tool, which can be used to anonymize packets. If you're on the Windows platform, then your best bet might be to try tools like TraceWrangler or WireEdit. If you're on another platform, then have a look at the Capture file anonymization section of the Wireshark wiki Tools page for a list of some other tools that could possibly help you.

If none of those tools work for you, I suppose you could always use the old-school hex-editor method of modifying packets as needed, but this is usually tedious, error-prone and difficult to do properly.

If you're not careful, you'll end up with malformed packets, so you really have to understand the pcap or pcapng file formats well before you attempt something like that.

I would highly recommend working with pcap files instead of pcapng files, as they are much simpler. And even then, you'll probably end up with checksum errors, which can be fixed or ignored if you wish later through multiple iterations.

Did I mention this can be tedious? Rather than using a binary hex-editor though, it might be easier to convert a pcap file using tshark e. Download Now.
