# Which value to use as node address for filtering in gcomm address.
|

# This is done due to some bugs in galera configuration. Thus we are

#
|

# [*skip_name_resolve*]
|
||||
# By default, MySQL tries to do reverse name mapping IP->hostname. In this
|
||||
# case MySQL requests can be timed out by clients in case of broken name
|
||||
# resolving system. If you are not sure that your DNS/NIS/whatever are configured
