Thread: Pg_hba.conf problem after unexpected IP change
Hello. I write for the following reason: I had configured a pg_hba.conf file, which I am using with some debian virtual machines, to be able to communicate between two different virtual machines.
Well, it turns out that at one point when I was using my virtual machines, suddenly and unexpectedly, the IP of one of the virtual machines changed.
I was trying to find out why the commands that I was executing between one virtual machine and the other did not work for me, until finally I came to the conclusion that the IP of one of my virtual machines had changed.
Well, then, I went to modify my pg_hba.conf file so that it reflected the new IP that I did not know why it changed, and to continue communicating between the two virtual machines, but it turns out that when I change my pg_hba.conf file, the connection still does not work for me .
The new line in my pg_hba.conf file is as follows:
host ds2 postgres 192.168.52.153/32 trust
and the line above was:
host ds2 postgres 192.168.52.150/32 trust
I clarify that right now when doing ip addr in the virtual machine whose IP changed unexpectedly, the following IP address appears: 192.168.52.153/24.
I will greatly appreciate a help please.

Yessica Brinkmann
Hello.
Thank you very much for your answer.
Yes, I restart the server after making the changes.

Did you reload or restart the server after making the change?

Hello.
Thank you very much for your answer.
The configuration actually works for me. After restarting my computer, I went to test again and it was already working. I assume that perhaps because they are virtual machines it was not only enough to restart the server, I think you also had to restart the computer.
It's what I think, or I don't know what else could have happened, but now it's working for me.
Thank you very much and greetings,
Yessica Brinkmann

Did you find the problem?
If not have you investigated whether whatever changed the IP also
enabled a firewall rule that blocks port(5432 I'm assuming)?
