CRUDE(8)		    System Manager's Manual		      CRUDE(8)

       crude - collector for rude (real-time UDP data emitter)

       crude  [	-h ] [ -v ] [ -d file ]	[ -P 0-90 ] [ -p port ]	[ -i ip_addr ]
       [ -l file ] [ -s	flow_id_list ] [ -n number ]

       Crude is	the receiver and logging utility for flows that	are  generated
       with  the  rude(8) tool.	In the default operation mode crude prints the
       information to standard output, so you'll have to redirect it  to  file
       if  you	like  to process it later on. Our recommendation is to log the
       data into file with the '-l' option. This reduces  I/O  operations  be-
       cause  the data is logged in binary format and soforth improves perfor-
       mance. You can decode the file later on with the	option	'-d'.  If  you
       want simple statistics of specific flows	use the	'-s' option. Note that
       options '-d' and	'-s' are mutually exclusive.

       -h     Print a short help.

       -v     Print the	version	information.

       -d     Decode the capture to stdout from	file, which was	 generated  by
	      the '-l' option.

       -P     Set  the	process	 in  real-time round-robin scheduling with the
	      given priority.  Needs root permission. Use with care.

       -p     Set the UDP port to listen to. The default is 10001.

       -i     Set the physical interface to listen from. The argument  is  the
	      IP  address for the specific interface in	numerical dotted nota-
	      tion (a.b.c.d). If this is not set, the program will  listen  to
	      all interfaces.

       -l     Log  the	capture	into file in binary format. The	default	action
	      is to print out the decoded info into stdout.

       -s     Print statistics of the given flowlist to	stdout.	 The  flowlist
	      is  a  comma  separated list of flow-identifiers.	The statistics
	      for each flow include:
		      o	number of received packets
		      o	num. of	packets	received out of	sequence
		      o	estimated number of lost packets
		      o	total bytes received
		      o	average	delay
		      o	absolute maximum jitter
		      o	throughtput

       -n     Set the number of	packets	to capture. The	default	 value	is  0,
	      which means until	interrupted with CTRL+C.

       I hear them crawling in my head.

       Please report any other bugs to the authors.
