Hi, and thank you for your prompt reply.
I am not trying to make any changes. Here's what's been going on:
Last night I edited the A record TTL of the `mydomain.tld.` of one of my users, which currently (still) is pointing to my current server IP. I changed that from 14400 to 300 because I was preparing for migration of my site to a new host.
Previously I had created a new user, and added them to the sudoers group. I had not given them access to the WHM though.
Today I noticed that all the other records have had their TTL changed from whatever value each was to 300. I asked my colleagues who have access to WHM if they have performed the change themselves, which they said they haven't.
I want to rule out that the change hasn't been performed by the new user via SSH. And to do that I need to know if it is possible to make such a change in the terminal, which then could be reflected in WHM as well.
I trust that the change I performed to that one A record should not have been applied to the remaining ones.
Hence my question.
