AXFR notifies?

[manarak]

I am forced to use AXFR to notify an external DNS server.

I inscribed the external DNS server's IP in the field "allow zone transfers", but somehow the transfers don't seem successful, because the external server never heard about my domain.

I check mydns.conf, and it says AXFR-allow: yes

did I miss something?

[manarak]

if I do
#mydns -d -v

I get:

AXFR is enabled
TCP ports are enabled
DNS update is not enabled
DNS notify is not enabled
DNS IXFR is not enabled
optional column "xfer" column found in "dns soa" table
ipv4_listerner: bind on sicket 6 (TCO) failed: 127.0.0.1+53: address already in use

[manarak]

my previous post is dumb.

Obviously, I have to stop the service before running it.

After stopping mydns and doing mydns -d -v again, it showed no errors: "listening on 4 addresses"


How can I check if the notifies are really sent to the other server or not?

[manarak]

any idea how I could diagnose the problem?

You can try to simulate a zone transfer with the dig command.

There also seems to be a bug in some mydns versions regarding zone transfers, for details please take a look here:

thanks!

modifying a query in mydns-ng shouldn't be difficult.

where is that file?


alternatively, I could also modify DNS_SOA column attributes and ISPConfig to set that active=1 value

[manarak]

I can't find the program... is that in a compiled file?
How to fix that?

The last intervention in the Sourceforge bug tracker is from march... *shudder*

Should I get another DNS server to work with ISPConfig 3?

err... in this thread they say that switching to mydns-ng is a solution?

But I think I use mydns-ng... How do I check which version I use?

[manarak]

ok, I manually changed the value in the DNS_SOA table to 1.

But still no joy, there are no notifies going out.

How can I trigger a notify manually?

Try to restart mydns.

Basically you can use any dns server even bind, but you will have to write a plugin for ispconfig that writes the bind config files based on the database content. For mydns there is no such plugin nescessary as mydns is able to read the data directly from the database withot the need of extra config files.

[manarak]

I already tried that - it does not seem to send the notifies.

Is there any way I can check on my server if the notifies are being sent?


I also tried to change a timer setting in DNS settings and leave active alone, but ISPConfig overwrites the active field even if I made no changes to it.

How to trigger a notify? Is there a shell command to do it?

[till]

You might want to ask this in the mydns-ng mailing list as I'am not a mydns developer and dont know the sourcecode of mydns.

[manarak]

yes, but you know what ISPConfig does when the DNS config is changed.

somehow MyDNS must know that a change has been made, in order to send the notify.

Does ISPConfig do something else besides writing the new DNS setting into the DB?
Is there a trigger-field somewhere, like "these DNS settings have changed, please send a notify"?

No, it just writes the changes to the DB.

As a workaround you can try this until the mydns developers have fixed the bug:

thank you - I'll try that.

An additional thing you might want to try:

short update on that. It seems to have been fixed in mydns-1.2.8.27. Which mydns version do you use? My other post with the link from the mydns mailink´glist is still worth a try.
