DHCP and DNS on different machines, can't ping client hostnames
by usr456 from LinuxQuestions.org on (#5T6XH)
Hello, i am very new to Linux, follwing a training course intro to Linux. But it's Christmas hollidays so, can't contact my trainer... And he gave us this assigment which is a bit ahead of what i can do... (sorry for my weird english btw)
----------------------------
Well my problem is basically summed up in the title:
I have Bind 9 installed on Ubuntu and a DHCP server on CentOS, all my servers are static and have their DNS pointed to the DNS server.
But none of them can ping the clients (Mint and Win10) by their hostnames (the servers do ping each others fine).
It's just server to client's hostnames. Doesn't ping. Zone file doesn't update.
Been driving me crazy for 5 days now, tbh...
Anyway here are the configurations:
Here's how i've configured my named.conf.local:
Code://
zone "testing.local" IN {
type master;
file "/var/cache/bind/db.testing.local";
allow-update { key rndc-key; };
allow-transfer { 127.0.0.1; };
};
zone "16.16.172.in-addr.arpa" IN {
type master;
file "/var/cache/bind/rev.testing.local";
allow-update { key rndc-key; };
allow-transfer { 127.0.0.1; };
};db.testing.local
