I am formally requesting a new DLT value to support capture traffic from my companies
So that'd be SITA: http://www.sita.aero/default.htm
LAN/WAN router/protocol converter device. Since this device supports WAN protocols, this new DLT will be used to provide/indicate that the data stream contains a number of WAN port specific pieces of information such as: - message direction - hardware signal line states (RTS, CTS, DCD, etc.) - transmit/receive error/status bits. - a protocol type indicator (Frame Relay, LAPB, IPARS, UTS, etc.)
So a given capture can have packets in it with multiple different protocol types?
This 5 byte header/control-structure will be prefixed to each captured data packet, but will not be considered as part of the 'data packet' that will be decoded as part of Wireshark, etc.
So will the format of that header be public, or private? - This is the tcpdump-workers list. Visit https://cod.sandelman.ca/ to unsubscribe.
