I fell asleep at my desk... and now it's working fine. I have no idea what was wrong or why it magically fixed itself.

After reboot, the problem came back again. Server refuses to resolve external names without "nameserver 8.8.8.8" in resolv.conf and gives the same SERVFAIL message when doing nslookup On Sat, Sep 5, 2020 at 9:02 AM Philip Offermans via samba < samba at lists.samba.org> wrote: > I think it?s the cache.

Thank you everyone for your help. I corrected my resolv.conf files as Peter Milesson suggested and then had to take a number of extra steps so now things are looking a little better. In case it helps anyone else in the future, here's what I found (plus I am now having problems resolving internal addresses). As far as I can see, the setup on both servers is identical (except they use their own

To get the question of why new servers, this one I'm using has hardware whose remaining life is measured in days. The elastic bands and sticky tape it is held together with won't hold for much longer. I'm using it to build and test a new environment, but then I need to migrate that onto something with a little more vitality before bringing it into production (in the next 56 hours). As

This should be an easy one. I'm trying to get postfix going. I've never done this before. I followed the directions at http://wiki.centos.org/HowTos/postfix.

I'm completely confused here and I'm hoping someone here has a setup they're willing to share, or help me configure things on my end. My connectivity is through Comcast, who unfortunately, does not offer ipv6 in my area. My connection goes like this: Comcast -> Motorola Surfboard Cable Router -> CentOS 6.5 server The CentOS server is multi-homed and manages the internal

Dear All With help from you all I am now at better stage. Special thanks to Robert. Atleast I am able to run all the required services (postfix, amavisd, clamd etc).

There seems to be a problem with my local dns server resolving mirror.centos.org. I know something about dns but obviously not enough to figure out what might be wrong here or how to fix this in bind configs. The SERVFAIL errors below seem to be related to AAAA and MX queries for the domain. Please advise. TIA. # host mirror.centos.org 8.8.8.8 Using domain server: Name: 8.8.8.8 Address:

Apparently I missed a step somewhere!

Hello, we encountered a problem with registry nic.at for tld .at and their transaction "BillWithDraw". This transaction allows an registrar to delegate authority back to registry. For a successful use of this transaction all nameserver-entries for the zone will be deleted by our application before nic-order will be sent to nic.at. Nic.at now checks all nameserver for existing

Please forgive me, I'm not sure what terminology to use here so this question may sound wrong. I have built two servers samba servers with a new domain. They replicate happily and I can seem to do everything I could ever want on them. DC01 holds all the FSMO roles and, as the first one built, acts as the "master" for DNS. Nothing works well on either server if DC01 is not at the
