sc_attach1

Usage

Overview

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
