DNS problem

[Kovács Péter]

Hello,


I have two important questions concerning to FreeBSD.

a. I have a Windows 2000 based Domain Name server.
Now this server always sends UDP connections to my FreeBSD box, but 
I don't know why. The FreeBSD has two IP's, but this Windows 
computer only sends these connections to one of the IP addresses. He 
leaves alone the other one
 How could this be?
Connection attempt to UDP FreeBSD_Box:1140 from Windows2000:53
Connection attempt to UDP FreeBSD_Box:1142 from Windows2000:53
Connection attempt to UDP FreeBSD_Box:1144 from Windows2000:53
Connection attempt to UDP FreeBSD_Box:1689 from Windows2000:53


b. I usually get these refused connections, although I don't have a 
username called 'webmaster'? How could this be? Why people try to 
use the 'webmaster' user?
mail saslauthd[237]: AUTHFAIL: user=webmaster service=smtp realm= 
[PAM auth error]
mail saslauthd[235]: AUTHFAIL: user=webmaster service=smtp realm= 
[Null login/password (saslauthd)]


Thanks,
	Peter
