Re: [Samba] Internal DNS CNAME not working
I upgraded to 4.0.4 and still did not have any success with CNAME records. As it turns out the problem was the syntax I was using to create the records. You need to include the full domain name and the period at the end. I think the samba-tool should validate these CNAME records when adding. Does anyone think that this raises to the level of a bug? bin/samba-tool dns add 127.0.0.1 mydomain.com my-server CNAME samba-001 -Uadministrator bin/samba-tool dns add 127.0.0.1 mydomain.com my-server CNAME samba-001.mydomain.com. -Uadministrator Wayne Andersen System Administrator Clima-Tech Corporation 208-947-1849 -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba

I'm a bit wondering about ;; WARNING: recursion requested but not available in the failing dig command. In former samba versions there _was_ a [global] smb.conf option recursive queries = yes samba-tool testparm -v --suppress-prompt should list all available options. Can you try that one, if valid? Cheers, Günter ps - i possible, you should upgrade samba! -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba
Re: [Samba] Internal DNS CNAME not working
Centos 6.4 64bit I have just sent the details of strace and dig, in a separate mail Frankly I do not know how to read the results. dnstracer -v my-server.mydomain.com fails with, return code 3 (Name error) dnstracer -v -q cname my-server.mydomain.com succeeds, returns Resource data (9)samba-001 It looks like my resolver only checks the local dns for A records.
