This software serves as the expert software for many of their analysers and I think now that the "Export to Ethereal" option (I take your point about the possible age of formats here), is only for their ADSL & Ethernet analysers, not my ISDN, & Q.Sig analyser. Capinfos cannot open its native .aps format,
Well, if you have some .aps files and the corresponding "export as text" dumps, we might e able to reverse-engineer the format.

Well, somebody at Aethra screwed up big-time there. They chose 17 as the link-layer type value; I doubt they were *so* crazy as to think that a PF log would be the right format, so they were probably looking at some non-OpenBSD system that didn't use 17 for some other purpose and decided "hey, this is available" without bothering to tell the Ethereal/Wireshark developers. Maybe they wrote their own plugin for Ethereal/Wireshark or built their own modified version.

If the frame begins with a LAPD header, try using 203 as the DLT_ value in text2pcap (after tweaking the hex dump if necessary to make text2pcap handle it).

As soon as I saw "Eye" I wondered whether this was at all related to Innoventif's EyeSDN capture devices:

...and, sure enough, I was right. They might be reselling the EyeSDN boxes under their own name - they're listed as a distributor:

Innoventif contributed support to Ethereal/Wireshark to read their file format.
