-r port range, Don't use -r and -p at the same time
-l query log DIRECTORY. Make sure that the directory is accessible. Default to stdout.
-e error log FILENAME or 'stderr'. if set to /dev/null, runtime error will not be recorded
-f filename. use pcap file instead capturing the network interface
-w white list. dont capture the port. Multiple ports should be splited by ','.
-t truncation length. truncate long query if it's longer than specified length. Less than 0 means no truncation
