Oct 31, 2017 · I used Wireshark many moons ago and need to return to the fold, but this time to sniff USB packets. I've installed USBpcap but there is no USB interface shown on Wireshark, just the Ethernet connections. I've looked at the documentation but can't find an idiot's how-to. The references to USB seem to be in the context of USB to Ethernet convertors.
Feb 15, 2020 · Wireshark 3.2 Some/IP Dissector Payload interpretation. I want to use the new integrated SOME/IP Dissector in Wireshark. If I go to the Wireshark Settings for the SOME/IP Protocol I have plenty of possibilities to dissect my payload. Setting up my UDP Ports, SOME/IP Services and SOME/IP Methods is not a problem and already working.
So data may be missing due to packet truncation, or there may be some protocol extension unknown to the dissector, or the actual protocol may be a different one than the dissector expects - e.g. as soon as an SDP re-negotiation changes the codec from G.729 to T.38, Wireshark starts applying a T.38 dissector to any UDP packet to/from the media sockets of the session, but in fact the change may not have happened that quickly, so still a couple of G.729 packets follow the SDP re-negotiation ...

Dec 4, 2020 · While a capture filter can be useful to limit the traffic under investigation, when troubleshooting certain issues the capture filter can drop packets that may be essential, e.g. icmp, so at first don't set a capture filter. The capture filter syntax is detailed here, some examples can be found here and in general a port filter is .
Oct 24, 2018 · Try this filter instead: (ip.src[0]==32 && ip.src[3]==98) || (ip.dst[0]==32 && ip.dst[3]==98) Those values, 32 and 98 are hexadecimal values for 50 and 152, respectively. The filter uses the slice operator [] to isolate the 1st and 4th bytes of the source and destination IP address fields. This filter also avoids any potential problems with ...
