Setup is as follows, Ubuntu 8.04 server in DMZ running Mysql 5
Remote connections from php on windows machines outside the DMZ are taking 5 seconds to establish (at which point the speed of mysql is fast) Connections from localhost are "instant"
Sounds like a standard dns issue to me so I have enabled skip-name-resolve and confirmed that is working (the error file logged skipped user entries) we still see the 5 second delay though. I have also tried adding the clients (netbios names, is this right?) as entries in the hosts file and the problem persists
I have run a tcpdump and from what I can gather, it looks like it is trying to do a netbios lookup (although I have zero experience reading tcpdumps!) I would imagine that is failing since this server is the only thing in the DMZ
I'm a little confused as to where to go from here.
