sc_attach

SC_ATTACH(1)						    BSD General Commands Manual 					      SC_ATTACH(1)

NAME

     sc_attach -- simple scamper driver.

SYNOPSIS

     sc_attach [-?v] [-i infile] [-o outfile] [-p port]

DESCRIPTION

     The sc_attach utility provides the ability to connect to a running scamper(1) instance, have a set of commands defined in a file be executed,
     and the output be written into a single file, in warts format.  The options are as follows:

     -?      prints a list of command line options and a synopsis of each.

     -i infile
	     specifies the name of the input file which consists of a sequence of scamper(1) commands, one per line.  If '-' is specified, com-
	     mands are read from stdin.

     -o outfile
	     specifies the name of the output file to be written.  The output file will use the warts format.  If '-' is specified, output will be
	     sent to stdout.

     -p port
	     specifies the port on the local host where scamper(1) is accepting control socket connections.

     -v      prints the current revision of sc_attach and exits.

EXAMPLE

     Given a set of commands in a file named infile.txt:

	tbit -M 1280 -u 'http://www.example.com/' 2620:0:2d0:200::10
	trace -P udp-paris -M 192.0.2.1
	ping -P icmp-echo 192.0.32.10

     and a scamper(1) daemon listening on port 31337, then these commands can be executed using

     sc_attach -i infile.txt -o outfile.warts -p 31337
