# To make this script work:
|
|
#
|
|
# - Edit FUZZ_HOSTS, FUZZ_DOMAIN, FUZZ_USER, and SYNC_DIR to reflect your
|
|
# environment.
|
|
#
|
|
# - Make sure that the system you are running this on can log into FUZZ_HOSTS
|
|
# without a password (authorized_keys or otherwise).
|
|
#
|
|
# - Make sure that every fuzzer is running with -o pointing to SYNC_DIR and -S
|
|
# that consists of its local host name, followed by an underscore, and then
|
|
# by some host-local fuzzer ID.
|
|
#
|
|
|
|
# Hosts to synchronize the data across.
|
