How to Setup DNS Server (Bind) on Linux Destro (Centos 8) Part 1 || in Arabic
Step 1: Install bind DNS on Linux
Step 2: Configure bind DNS server
Step 3: Create a forward DNS zone file for the domain
Step 4: Create a reverse DNS zone file for the domain
Step 5: Test the Bind DNS server from a client system
More Explain:
type: Stipulates the role of the server for a particular zone. the attribute ‘master’ implies that this is an authoritative server.
file: Points to the forward / reverse zone file of the domain.
allow-update: This attribute defined the host systems which are permitted to forward Dynamic DNS updates. In this case, we don’t have any.
TTL: This is short for Time-To-Live. TTL is the duration of time (or hops) that a packet exists in a network before finally being discarded by the router.
IN: This implies the Internet.
SOA: This is short for the Start of Authority. Basically, it defines the authoritative name server, in this case, dns-primary.linuxtechi.local and contact information – admin.linuxtechi.local
NS: This is short for Name Server.
A: This is an A record. It points to a domain/subdomain name to the IP Address
Serial: This is the attribute used by the DNS server to ensure that contents of a specific zone file are updated.
Refresh: Defines the number of times that a slave DNS server should transfer a zone from the master.
Retry: Defines the number of times that a slave should retry a non-responsive zone transfer.
