[SOLVED] DNS Bind

JJJCR · 07-07-2021, 04:26 AM

hello guys, followed this link to install DNS. https://www.unixmen.com/setting-dns-server-centos-7/

If need to add static entry to DNS just need to add items here:

vi /var/named/forward.dnsweblocal

And adding entry, like this data below will be ok?

localhost A 127.0.0.1

www.local-website.com A 127.0.0.1

www.other-local-website.com CNAME fake-hostname.com.

Thanks, for any help.

Yes, but you also need to increase the serial number and reload the zone.

You need to include the file forward.dnsweblocal as a zone, using the examples given then restart named/bind.

Hi Bathory, thanks for the input.

The serial number has to be increase manually? Every time a new entry is added?

If you're editing the zonefile by hand, then you need to do it manually. If you're using a gui tool it's done automatically

BTW you also need to pay attention at the trailing dots in hostnames, because the lack of them makes zonename to be added at the hostname. So in your OP the 3 records are actually: localhost.local-website.com, www.local-website.com.local-website.com and www.other-local-website.com.local-website.com.
It should look like:

Code:

localhost. A 127.0.0.1

www.local-website.com. A 127.0.0.1

www.other-local-website.com. CNAME fake-hostname.com.

need your help again guys, i manually add the DNS to one of my laptop.

I'm able to do an nslookup hostname.xyz.local, and able to resolve the IP Address correctly.

I added an entry to the DNS as:

hostname.xyz.local. IN A 192.168.1.11

The host or the IP above is hosting a web locally.

I'm able to access it via: http://192.168.1.11/login/#/users

How to add a DNS entry to this?

I tried inputting in the browser as: http://hostname.xyz.local/login/#/users

But it just shows "no internet" in chrome

Any input on this guys on how to resolve?

Thank you.

You said you added that entry in your dns!

If you're trying to access http://hostname.xyz.local/login/#/users from a different computer, make sure that it also uses your dns server as a resolver.
Run "dig hostname.xyz.local" from the client and see what you get.

Thanks, Bathory.

The URL entry was changed to: http://hostname.xyz.local/login/r/users

Yes, it seems to work now. I think just need to add entry for Google DNS in named.conf, so if the item is not local then will go directly to external DNS.

Is this safe? Or what should be the good approach?

Thanks again.

You don't need a third party resolver. The local nameserver that is authoritative for your zone(s), can also resolve external domains.
Perhaps google dns is faster, but on the other hand, I guess it uses your lookups for ads and such.
