کمک فوری : ابیوز های جدید ovh در مورد dns

[hoka]

سلام به همه ی دوستان

الان یک ابیوز از OVH گرفتم که در زیر میبینید

We have detected an incorrect DNS configuration on one or more IPs of

*****55.kimsufi.com ((list at end of the email).

This configuration fault is very serious as it allows anyone on the
internet to use your DNS server(Open Resolver). By way of a rather
simple mechanism (spoof IP), an attacker is using your server
to create a distributed denial of service (DDOS by DNS amplification)
directed at a target server.

We request that you change the configuration of your DNS server
immediately to prevent recursive resolutions (other than for your own
server). You will find information to help you configure your server
here: Secure your DNS server - OVH

Once corrected, you can test the configuration of your DNS server with
our test page:  https://www.ovh.co.uk/cgi-bin/tools/dns_security.cgi

WARNING: in 24hrs time we will re-check the status of your server and
we could be obliged to block it if you have not corrected your
configuration.


*** In the event of you being unable to resolve this problem ***

Our teams will be able to configure it for you if a supported platform
is involved, at a charge of 20.00€ excl. VAT. To request this service,


Here are the IPs affected by this problem

من دی ان اس رو تنظیم کردم به آی پی ای که گفت ولی هرکاری میکنم فایل های مربوط به nemed رو پیدا نمیکنم روی سرورم . الان هم فقط وقتی named رو استاپ میکنم تستی که خود دیتاسنتر داده صحیح میزنه ولی وقتی nemed استارت باشه تست خطا میده

دوستان کسی میدونه باید چکار کرد ؟ ممنون میشم سریع تر هم جواب بدید که سرور به مشکل برنخوره
