Hello.

We are attempting to capture on a network interface with ethereal version
0.8.18 on an AIX system version 5.2 maintenance level 4. The devices are
part of IBM 10/100 Mbps Ethernet PCI Adapters. We have installed the
ethereal version that comes with "AIX Toolbox for Linux Applications".
When we run ethereal from the root account, the interfaces don't show up in
the list of interfaces in the "Interface:" field. If we try to run ethereal
entering the name in the "Interface:" field and capturing on that device, we
get the following error message:
	The capture session could not be initiated (/dev/bpf0: there is a
request to a device or address that does not exist.) 
	Please check to make sure you have sufficient permissions, and that
you have the proper interface or pipe specified.
If we run tcpdump on the same interface, the capture begins. The strange
thing is that, if after capturing with tcpdump we run again ethereal, the
interfaces show up in the list of interfaces and everything works ok. If we
reboot the system, the problem arises again until we run tcpdump.
Thanks in advance.
