Hi,

We have implemented a version of packet.dll (WINPCAP), that allow us to
connect to a remote device and collect packets from there. We choosed
to replace packet.dll to avoid changing the packet interface in e.g. Ethereal.

It is possible to select either a single adapter or adapters covering
more than one interface (e.g. "lan0", "all" or "atm-all").
Since "all" might include different interfaces (e.g. ATM or LAN) it would be
nice if it (optionally) was possible to tell the LinkType for each packet captured.
An ATM LLC header cannot currently be decoded if LinkType is LAN (also TCP is not
recognized when LinkType=ATM by Capture Statistic Window, TCP stream analysis etc.).
Also sometimes it is valuable to know whether a packet was **sent** or **received** on
a specific link/interface.

A final wish is if it could be possible to specify the signal number shown in e.g.
Ethereal. In that way it can be seen where packets have been lost (numbers missing).

And since the wish list never ends - it could be nice if it was possible to
add a text comment between the packets (e.g. "packet above discarded due to xxxx").
Maybe some of the existing

Any comments?
