Accidentally ran rndc-confgen on a working BIND box

[Luis Navarro]

I've been running BIND on Ubuntu 22.04 for over a year and it has been
running perfectly as my primary DNS server.  I'm currently using BIND
9.18.28.

 

I'm currently setting up BIND on another box (as a secondary DNS server) and
accidentally just ran "sudo rndc-confgen -a" on the first box.  From what I
can tell, running this command overwrote the previously installed
"/etc/bind/rndc.key" file with a new one.  

 

I'm vaguely familiar with rndc but don't think I've ever used it directly.
It is possible the BIND tools I typically use call it.  Anyway, the first
box *seems* to still be working normally.

 

Questions:  Did I break anything by running "rndc-confgen"?  Is there
anything else I need to do on the first box to move forward with the new key
file?  Or should I restore the key file from a backup?

 

Thanks in advance!

Luis
