Facter / FACT-3049 Reading the `/etc/resolv.conf` file for the domain value Issue Type: Improvement Affects Versions: FACT 3.14.1 Assignee: Unassigned Created: 2021/05/31 1:46 AM Priority: Normal Reporter: Selvakumar Azhagarsami Per our environment settings, it is unable to get the FQDN from hostname -f. So, we have to read the /etc/resolve.conf for the domain value. But, it is not a must to set the 1st search domain as the server domain name in the /etc/resolve.conf file. So, do U think we have to review this mechanism to get the domain info? Add Comment

Re: Reading the `/etc/resolv.conf` file for the domain value Hi Paul Liong would it be possible to provide more detail here on how you would like this mechanism to work? At the moment it uses gethostname(), if this doesn't return anything it then searches the /etc/resolv.conf. How would you like this to operate to best suit your use case? If you can provide as much detail as possible, it will help us to see if a change is feasible. Thank you!

Hi Patrick Grant,   Thanks for your waiting. Well, it is noticed that the search field specify in /etc/resolv.conf may not be the FQDN of the servers.  So, will it be better to get the FQDN by looking up DNS record from the primary ip address? Regards Paul

Paul Liong, as per Selvakumar Azhagarsami comment, facter will use /etc/resolv.conf only when DNS resolving fails (`gethostname`/`hostname -f` are doing DNS lookup).

Going to close this ticket out at this point, it has been explained that facter will use /etc/resolv.conf only when DNS resolving fails. If we are missing any detail here, this can be reopened but for now there appears to be no issue. Thanks!

Paul Liong, In case the DNS resolving fails, how could facter retrieve the correct info?
