# igmpproxy supports both a debug mode and verbosity, which are very useful
|
|
# when something isn't working.
|
|
#
|
|
# Debug mode will print everything to stdout instead of syslog. Generally
|
|
# verbosity should NOT be set as it will quickly fill your syslog.
|
|
#
|
|
# Put any debug or verbosity options into IGMP_OPTS
|
|
#
|
|
# Examples:
|
|
# OPTIONS="-d -v -v" - debug mode and very verbose, this will land in
|
|
# stdout and not in syslog
|
|
# OPTIONS="-v" - be verbose, this will write aditional information to syslog
|
|
