Permission problem when restarting BIND DNS Server
« on: July 25, 2024, 11:39:40 PM »
I have a server that is running with 5 accounts that were manually added. Today I had to add the last 2 accounts to it. For those accounts I used the cpanel to CWP migration method. The account imported fine but the dns records in one of them were botched. They referenced the old nameservers.

I used the rebuild zone button and that looked like it should have fixed the issue but the one zone still would not get an IP Address.

So I did the dumb thing and restarted BIND DNS Server from the Dashboard. It stopped it fine but when it tries to start it there is a permission issue.

I am not sure what I broke or how to fix it.

Hi, you have to check permissions for /var/named folder. I suppose it has the wrong owner.
You can ask me to solve any problem with your server for some money in pm  ;)

Thank you I have no idea how that happened.

Migration burp?

Had I looked that would have stuck out like a sore thumb. I just never thought that could have been an issue.
