64885http://bugs.mysql.com/bug.php?id=64885No FeedbackServerMySQL Server does DNS-PTR lookups even when skip-name-resolve is activeI'm running my MySQL server with the --skip-name-resolve. I verified that this option is enabled via: mysql> show variables LIKE 'skip_name_resolve'\G *************************** 1. row *************************** Variable_name: skip_name_resolve Value: ON 1 row in set (0.00 sec) Unfortunatelly SQL connections from remote hosts are very slow in the handshake phase. I found that this is the case for hosts where no PTR record is set. After that I started a tcpdump on the mysql-server host looking for DNS queries and I see several PTR lookup each time a remote client wants to connect. 2469292133370940514207625085.1.61,5.5.17LinuxAnyS2 (Serious)
