Re: [xcat-user] [External] Manually add CNAME records to xcat-managed DNS?

[Calvin S. <c.s...@qm...>]

Apologies for late/slow reply, Jerrod (at al). Thanks very much for yours

The issue is no so much what makedns -n will do , but how to actually create a CNAME record in xcat​'s DNS

Running nsupdate using a keyfile containing the key data that exists in both named.conf and in passwd tabdb, any change attempt results in :

; TSIG error with server: tsig indicates error
update failed: NOTAUTH(BADKEY

What I'm hoping to discover is how to add a record manually using nsupdate in the same manner as xcat does running makedns <node>.

Anyone else is likely to be more fresh on this, but some feedback based on my recollection is that apart from '-n', makedns shouldn't step on your CNAME.  Further, you probably shouldn't need '-n' except maybe once to get started (with the update key to enable nsupdate-like updates like xCAT normally uses it).  You should be able to add nodes or change ip addresses without '-n'.

Back up just in case, it has been quite a while since I had reason to delve into the DNS stuff.

Hi

We're somewhat limited due to the being unable to add CNAME records to xcat's DNS records. Wonder if anyone has an nsupdate procedure for doing so?  I realise that "makedns -n" would completely burn any manual changes that would need to be reinstated.

thank you,
