Correct me if I'm wrong but wouldn't tcpdump have to be restarted after
the logrotate? I'm under the impression that it would just continue to
output to the old inode even if the file occupying it changes name and
the restart functionality of newsyslog(8) isn't really bright enough to
restart tcpdump with all its initial parameters.
I'm using sysutils/cronolog for my Apache logs so I don't have to
restart Apache at all for the logrotate. Unfortunately cronolog doesn't
seem to have a size option to trigger the rotation though. Maybe there's
another alternative for the OP?
