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
