SC_EROSPROBER(1) General Commands Manual SC_EROSPROBER(1) NAME sc_erosprober -- scamper driver to periodically probe addresses and ro- tate output files. SYNOPSIS sc_erosprober [-a addrfile] [-c command] [-I interval] [-l logfile] [-o outfile] [-O option] [-p port] [-R rotation] [-U unix-scamper] [-x unix-control] DESCRIPTION The sc_erosprober utility provides the ability to connect to a running scamper(1) instance and use it to periodically probe a set of addresses at a defined interval, and periodically rotate the output file at a de- fined interval. The supported options to sc_erosprober are as follows: -a addrfile specifies the name of the input file which consists of a se- quence of IP addresses to probe, one address per line. -c command specifies the command to use with each address. sc_erosprober supports the trace and ping commands, and their options, in scamper. scamper(1) documents the options available in trace and ping. -I interval specifies the probe interval, in seconds, between probing each address. sc_erosprober will spread the probing of the ad- dresses across the interval. If there are 10 addresses to probe at an interval of 20 seconds, then sc_erosprober will is- sue a command every two seconds. -l logfile specifies the name of a file to log progress output from sc_erosprober generated at run time. -o outfile specifies the prefix of the name of the output file to be writ- ten. The output file will use the warts(5) format. sc_erosprober will create a sequence of files named using the prefix and a timestamp. -O options allows the behavior of sc_erosprober to be further tailored. The current choices for this option are: - noshuffle: do not shuffle the order of addresses before probing starts. - nooutfile: do not write to warts files, just do the prob- ing. - gz: gzip compress the warts output. - warts.gz: gzip compress the warts output. - bz2: bzip2 compress the warts output. - warts.bz2: bzip2 compress the warts output. - xz: xz compress the warts output. - warts.xz: xz compress the warts output. -p port specifies the port on the local host where scamper(1) is ac- cepting control socket connections. -R rotation specifies the rotation interval, in seconds, between rotating output files. -U unix-scamper specifies the name of a unix domain socket where scamper(1) is accepting control socket connections. This socket is used by sc_erosprober to send probing commands to scamper(1) -x unix-control specifies the name of a unix domain socket where sc_erosprober is accepting control socket connections. This socket can be used by a local process to adjust the probing list at run time. EXAMPLES Given a set of IPv4 and IPv6 addresses contained in a file named addrs and a scamper process listening at sock configured to probe at 100 packets per second started as follows: scamper -U scamper-sock -p 100 the following command will ping the addresses every two minutes using one packet, and create an output file every thirty seconds prefixed with foo: sc_erosprober -U scamper-sock -a addrs -o foo -I 120 -R 30 -c 'ping -c 1' The following command will traceroute towards the addresses every 15 minutes, creating an output file every minute, with an sc_erosprober control socket: sc_erosprober -U scamper-sock -x erosprober-sock -a addrs -o foo -I 900 -R 60 -c 'trace' To add an address to the probeset at runtime, using netcat, use: nc -U erosprober-sock +192.0.2.1 To remove an address from the probeset at runtime, using netcat, use: nc -U erosprober-sock -192.0.31.60 SEE ALSO scamper(1), sc_wartsdump(1), sc_warts2text(1), sc_warts2json(1), warts(5) AUTHORS sc_erosprober was written by Matthew Luckie.
