Hi, I'm attempting to run: tcpdump -C 100 -U -i re0 -s 0 -v -w some-dump-file on stable/10 r281235, the 20150407 amd64 snapshot. The re0 interface is in monitor and permanent promiscuous mode, i.e. ifconfig_re0="up monitor promisc". I'm expecting to see files named: some-dump-file some-dump-file1 some-dump-file2 some-dump-file3 some-dump-file4 ... each file about 100 MB large, i.e. ~100,000,000 bytes. I only see the some-dump-file, and it has now reached 15 GB. As a contrast, the -G option expects the -w argument to contain strftime(3) time formatting to enable timestamping of each file. The -C option has no such requirement documented. Is this a pilot error or a genuine bug? I could switch to using: -G 3600 -w 'some-dump-file-%Y-%m-%dT%H-%M-%s.pcap' but I want a fixed file size more than a fixed time interval for each file.

It should also be noted that the extensions should be installed on the guest, not the host. -- Mike Clarke
