    Default Yast dns server module

    Hi,

    I was playing with the DNS yast server module. I created a test domain,
    entered my machine record, and then tested the host command, both direct
    and reverse. Reverse resolution did not work, the reverse zone file was not
    created (but the reverse zone file for 127.0.0.* was created).

    Did I do something wrong, or simply YaST doesn't create it?

    I haven't tried it, and doubt there is much purpose to creating a Reverse Lookup Zone for the localhost address range.

    Recommend you test using a normal private or public range instead.
    If a "proper" address has already been assigned to your machine, you can try using that, or bind a new address to your NIC.
    Or, you can point your test Domain to another suitable machine instead of your own machine... I frequently do that (create custom Domain names not publicly registered) for my own private use when I setup Dev environments... Both for regular use as well as to test software using FQDNs.

    The localhost is created with both direct and reverse zone files (not my
    doing). It is the normal private zone I created that did not.

    The question is whether this is a yast fault, or mine. I know how to do it
    manually, I just want to know if the yast dns server module should do it.

    Don't know if what should be standard practice for YAST, but AFAIK configuring zones all DNS servers do not create reverse lookup files by default, you need to create them separately and in addition to the original zone file(s).

    Yes, but that's my question.

    When I create a zone manually I write both direct and reverse zone files.
    But YaST did not, and I'm asking whether I did something wrong, or is this
    a YaST feature/bug.

    I'm not asking how to do it. I'm asking whether YaST does or does not do it.

    I wouldn't necessarily expect it to for the reason that there are times
    when you want an address to have multiple A records, for instance, you
    may use the same server as a DNS server, a web server and a mail server.
    You might call it ns.domain, www.domain and smtp.domain. A forward
    record may have many names but a reverse record points to a specific
    name. If YaST automatically wrote the reverse record that last one done
    would overwrite the record. That may or may not be what you want.

    I don't manage my dns servers via YaST, so I'm flying blind here, but a
    check box asking whether to create the reverse entry would be a nice
    feature if it's not already there. Then a person could decide when they
    create the record whether it is appropriate to create the reverse record
    too. But I don't know if that's in there or not.

    True.

    Ah, that's a reason. Interesting.

    It seems a missing feature, then.
