The standard libpcap compiled for Linux has a timeout problem; it
doesn't support the timeout argument to "pcap_open_live()".

The current version of Ethereal attempts to work around this, so its GUI
shouldn't freeze when capturing on a not-so-busy network.  If its GUI
does freeze when that happens, please send a note about this, indicating
which version of which distribution of Linux you're using, and which
version of libpcap you're using, to ethereal-dev@zing.org.

The current version of Ethereal should work with versions of libpcap
that have been patched to fix the timeout problem, as well as working
with unpatched versions.

An additional problem, on Linux, with current versions of libpcap is
that capture filters do not work when snooping loopback devices; if
you're capturing on a Linux loopback device, do not use a capture
filter, as it will probably reject most if not all packets, including
the packets it's intended to accept - instead, capture all packets and
use a display filter to select the packets you want to see.
