hello,
I don't know how to configure servor dns on linux,please help I thanck YOU
You need to help yourself a little before asking for assistance in the way that you have.
What have you done to attempt to configure DNS yourself? Have you read the countless articles and HOWTOs available? What type of nameserver are you attempting to set up? Have you tried searching Google for "Linux DNS Server", for example?
Please feel free to ask specific questions, but people are not going to be willing to provide complete solutions when the documentation is readily available (countless times) elsewhere.
Thanks,
ZB
