NAME

     sc_attach — simple scamper driver.

SYNOPSIS

     sc_attach [-?dDv] [-c command] [-i infile] [-o outfile] [-O options] [-p [ip:]port]
               [-P priority] [-R unix-domain] [-U unix-domain]

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.

     -d      prints each command sent to scamper(1) on stderr.

     -D      causes sc_attach to operate as a daemon.

     -v      prints the current revision of sc_attach and exits.

     -c command
             specifies the scamper(1) command to prepend to each address in the input file.

     -i infile
             specifies the name of the input file which consists of a sequence of scamper(1)
             commands or addresses (with the -c option), one per line.  If '-' is specified,
             commands 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.

     -O options
             allows the behavior of sc_attach to be further tailored.  The current choices for
             this option are:
               -  random: shuffle the input commands randomly.
               -  impatient: send commands to scamper without waiting for scamper to ask for
                  them.

     -p [ip:]port
             specifies the IP address and port where a scamper(1) is accepting control socket
             connections.  If an IP address is not specified, sc_attach connects to the specified
             port on the local host.

     -P priority
             specifies the mixing priority scamper(1) should assign to the source.

     -R unix-domain
             specifies the unix domain socket on the local host where a remote scamper(1)
             instance is accepting commands.

     -U unix-domain
             specifies the unix domain socket on the local host where a local scamper(1) isntance
             is accepting commands.

EXAMPLES

     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

     Given a set of addresses in a file named infile2.txt:

        2620:0:2d0:200::10
        192.0.2.1
        192.0.32.10

     these addresses can be pinged with sc_attach operating as a daemon with:

     sc_attach -D -c 'ping' -i infile2.txt -o outfile2.warts -p 31337
