sc_ally
SC_ALLY(1) BSD General Commands Manual SC_ALLY(1)NAME
sc_ally -- scamper driver to run Ally on a list of candidate aliases.
SYNOPSIS
sc_ally [-?D] [-i infile] [-o outfile] [-p port] [-U unix-socket] [-w waittime] [-q attempts] [-t logfile]
DESCRIPTION
The sc_ally utility provides the ability to connect to a running scamper(1) instance and have a set of IPv4 address-pairs testsed for aliases
using the Ally technique. For each address pair in the file, sc_ally establishes which probe methods (UDP, TCP-ack, ICMP-echo) solicit an
incrementing IP-ID value, and then uses the Ally technique on pairs where a probe method is able to obtain an incrementing IP-ID for both
addresses. The output is written to a warts file. The options are as follows:
-? prints a list of command line options and a synopsis of each.
-D causes sc_ally to detach and become a daemon.
-i infile
specifies the name of the input file which consists of a sequence of IPv4 address-pairs, one pair per line.
-o outfile
specifies the name of the output file to be written. The output file will use the warts format.
-p port
specifies the port on the local host where scamper(1) is accepting control socket connections.
-U unix-socket
specifies the name of a unix domain socket where scamper(1) is accepting control socket connections.
-w waittime
specifies the minimum length of time, in seconds, to wait between completing a measurement to a particular IP address and issuing the
next.
-q attempts
specifies the number of times to try Ally when one of the addresses is unresponsive.
-t logfile
specifies the name of a file to log output from sc_ally generated at run time.
EXAMPLE
Given a set of IPv4-address pairs in a file named infile.txt:
192.0.2.1 192.0.32.10
192.0.2.2 192.0.31.8
192.0.2.3 192.0.30.64
and a scamper(1) daemon listening on port 31337, then these address-pairs can be tested for aliases using
sc_ally -i infile.txt -o outfile.warts -p 31337
