Re: [tcpdump-workers] Linktype needed
Hello, Yes, our driver will supply raw packets with the header specified by the BACnet specification. Therefore we would appreciate your first suggestion, which would be naming the linktype DLT_BACNET_MS_TP. Thanks in advance, Martin Angler -Ursprüngliche Nachricht- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Im Auftrag von Guy Harris Gesendet: Samstag, 5.

Now I've seen, that there is no linktype that specifies BACnet MS/TP. So I wanted to ask whether you could define/implement a corresponding linktype. I infer from some stuff I've seen that BACnet MS/TP is a link-layer protocol atop which the higher-level BACnet protocols can run (just as they can run atop UDP and 802.2). Will your driver supply raw packets with a header specified by the BACnet specification (the ISO standard appears to cost over 350 CHF, so I haven't bought it), or will it supply some form of cooked software that might not be what other BACnet MS/TP capture mechanisms might supply? If the former, the linktype should probably be called DLT_BACNET_MS_TP or something such as that; if the latter, the name should probably have something in it to indicate what type of header it is (see, for example, DLT_ARCNET, which should perhaps have been DLT_ARCNET_BSD, and DLT_ARCNET_LINUX, or DLT_APPLE_IP_OVER_IEEE1394, which is not raw Firewire but has a synthetic header). Other people that worked on an MS/TP dissector (www.abmlinux.de) already tried to contact you, but without success. I don't think I've seen that on tcpdump-workers. Do they have their own driver and, if so, does it supply the same link-layer header (if not, it'd need a separate DLT_ value)? - This is the tcpdump-workers list.

[tcpdump-workers] Linktype needed

So I wanted to ask whether you could define/implement a corresponding linktype. Other people that worked on an MS/TP dissector (www.abmlinux.de) already tried to contact you, but without success. I hope you can arrange this for us ASAP. Regards, Martin Angler -- Email.it, the professional e-mail, gratis per te: http://www.email.it/f Sponsor: Vorresti vincere 1500 euro???
