Title: I need help using the rpcap functionality with Ethereal
Hi.
Regarding your question about PPP/WAN support, I think that
that Ethereal error message is somewhat misleading: winpcap 2.3 supported
PPP/WAN but, due to the large number of user problems (blue screens), we
disabled PPP support into winpcap 3.0.
We have enabled PPP support again in WinPcap 3.1beta (using a
completely different technique), that has been released a couple of weeks ago.
Note that PPP is NOT supported on NT4.
I suggest you to try this beta release.
Have a nice day
GV

Subject: [WinPcap-users] I need help
using the rpcap functionality with Ethereal
All,
I put the following string in the capture interface
for ethereal:
rpcap://10.2.3.4:2002/12345
A capture of my communications with the remote
rpcapd reveals that my PC sent the following 16 bytes of TCP data to the
remote daemon:
0x00 0x08 0x00 0x00 0x00 0x00 0x00 0x08 0x00 0x00
0x00 0x00 0x00 0x00 0x00 0x00
The remote agent replies with 64 bytes of TCP data,
part of which is the following message: Authentication failed; NULL autentication not permitted.
Ethereal then gives me the following error
message:
The capture session could not be initiated
(Authentication failed; NULL autentication not permitted.). Please check that you have the proper interface
specified.
Note that the WinPcap 2.x version of the driver
Ethereal uses for packet capture on Windows
doesn't support capturing on PPP/WAN interfaces in Windows NT/2000/XP/2003 Server, and that the WinPcap 3.0 and later
versions don't support capturing on PPP/WAN
interfaces at all.
Anyone know what the problem is??
