1.204.1. RHBA-2009:1605: bug fix update
The tcpdump tool is a command line utility for monitoring network traffic.
* when run on 64-bit architectures, tcpslice read the timestamps in pcap files as 64-bit values despite them always been stored as 32-bit. Consequently, rather than extracting packet-trace file portions as expected, tcpslice returned a "couldn't find final packet in file" error. With this update tcpslice reads pcap timestamps as 32-bit values and now works as expected on 64-bit architectures. (
BZ#485670)
* running "tcpdump -i [n]", where [n] was an invalid interface index, caused tcpdump to SEGFAULT rather than return an "Invalid adapter index" error. tcpdump now explicitly checks for the last entry in the device list. If the [n] specified is higher than this entry, it returns "Invalid adapter index" as expected and does not crash. (
BZ#497819)
All tcpdump users should upgrade to these updated packages, which resolve these issues.
