Hi nitass,

 

 

I configured alias service port to 53 instead of any port and works find, but still this script monitor dosn't work with me.

 

 

I set the followings arguments:

 

 

(IP DNS Server) (Port) (Domain) (Excepted String)

 

 

I'm not sure what expected string when it is successful.

 

 

Thank you.
