Subject: making ROOT files with all data for one host 

The program which creates ROOT files with _all_ data send
and received by a specific host is called

	root4host

and lives in /ncc/ttpro/bin  (only works on ginkgo & kauri)

Usage:	root4host  <hostname> <datestring>

where <datestring> is YYYYMMDD (e.g. 19990830)

output file is called /ncc/ttpro/spool/tt<ID>.ripe.net.<datestring>.root
where <ID> is the id-number of the box (i.e. "root4host osdorp 19990901"
will make a file tt02.ripe.net.19990901)

To make the file available via FTP, I suggest to use 'rcp' to copy
it to the ftp.ripe.net machine as we do not have FTP service on ginkgo
(yet).


=N=O=T=E= 

in order to run root4host, one has to set environment variables:

	ROOTSYS=/usr/local/root
	LD_LIBRARY_PATH=:/usr/local/root/lib:/ncc/ttpro/lib


Source for the program (including makefile) can be found in

	/ncc/ttpro/src/ROOT/root4host

It works by "chaining" all .root files found in /ncc/ttpro/root_data
hierarchy for the specified date, going through the chain once
and filling a new "tree" with delay objects whose SourceId or TargetId
match the Id of the specified host.

P.S. For the record: the conversion hostname -> testbox_id is done
     by reading the LIST_OF_TESTBOXES file from /ncc/ttpro/config

Will improve this in the next version :-) --- Rene
