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 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.
