Hi guys
I experienced this problems some days ago using tcpdump and tethereal.
I made a capture with tcpdump in order to get OSPF packets. My filter was ip[21]==89. I saved my data into a pcap file, but when I opened it with ethereal I found many packets marked [Short frame], and effectively they where truncated. I made the same capture with tethereal (same options) and I got a different result: the packets where captured correctly, at full lenght.
These are my versions:

Red Hat Linux release 8.0 (Psyche)
tcpdump-3.6.3-17.8.0.3
ethereal-0.9.13-1.80.1
libpcap-0.6.2-16

Any idea?
