And what exactly is "my IP"? One could hazard a guess based on your
message's headers, but it would be easier if you told us.

Have you tried using a utility like "dig" to execute reverse lookups
along the responding domain name server chain? Verbose output should
offer clues about where the data originates.

Origin of reverse lookup

2021-06-18 Thread techlists

Hi,

I had my ISP configure a reverse lookup years ago.  They say they no 
longer offer that service and there is no reverse lookup for my IP.


I keep running into this old reverse lookup and do not know where it is 
coming from.


When I run https://intodns.com/ it shows this reverse lookup and not the 
one I just configured on my local box.


Any thoughts on how I might resolve this or find who is hosting this 
reverse lookup?


Thanks!!

RE: Windows support has been discontinued in BIND 9.17+ (Was: Important: A significant flaw is present in June BIND releases 9.16.17 and 9.17.14)

2021-06-18 Thread Richard T.A. Neal
The next Event Log entry on my system immediately after "using 1 UDP listener 
per interface" is:

loading configuration from 'C:\BIND\etc\named.conf'
(because that's my BIND installation folder obviously).

If I intentionally make a typo in any of my config files (eg named.conf, 
named.conf.options etc) and try and start the ISC BIND service I get:

Windows could not start the ISC BIND service on local computer.
Error 1067: The process terminated unexpectedly.

And that’s exactly the same error message that you’re getting.

Have you tried dropping to a command prompt and then running "named-checkconf" 
from within the "bin" subfolder of your BIND installation folder? That will 
tell you if it detects an error in any of your configuration files. I know you 
may not have changed them between upgrading from 9.16.12 to 9.16.18, but maybe 
there's something in there that BIND 9.16.12 was OK with but which 9.16.18 is 
not happy.

For example if I intentionally add a simple 'x' at the very end of my 
named.conf and then run C:\BIND\bin\named-checkconf I get:

C:\BIND\bin>named-checkconf
C:\BIND\etc\named.conf:8: unknown option 'x'
C:\BIND\etc\named.conf:8: unexpected token near end of file

do I need to configure a Caching Server

2021-06-18 Thread techlists
I am building a home PHP hosting server for learning.  I have a 
commercial connection to the Internet so no blocked ports and my ISP 
allows servers.


I believe I only need a Primary Master Server.  Is this the case?

My question is, do I need to configure a Caching Server?

In /etc/bind/named.conf.options:


[...]

forwarders {
 1.2.3.4;
 5.6.7.8;
};

[...]

Do I need to set the forwarders?

Thank you for all your help!!

It ought to be possible to write a front-end to listen on the standard control

If your Application log is too busy you can also filter by event source "named"

the development and support teams has found other use cases that would affect

Only zones with wildcards affected on authoritative servers (Was: Important: A significant flaw is present in June BIND releases 9.16.17 and 9.17.14)

2021-06-18 Thread Ondřej Surý
Hi,

let me add more details to the issue.

# Who’s affected

Authoritative server operators operating zones with wildcard records (f.e. 
*.example.com)

# What’s affected

Queries hitting the wildcard records with capital `W`

# How to test?

dig IN A W.example.com @127.0.0.1

You need to adjust this to match your zone name, server IP address and the 
rrclass and rrtype of the wildcard record.

# Is there a hotfix?

The patch to fix this issue is available at:
https://gitlab.isc.org/isc-projects/bind9/-/commit/52cc9ff372ba637289d1e8f35d1f3f35d46ea25f.patch

# Are the ISC packages affected?

The packages with the hotfix applied were pushed into the repository and are 
either already built
or are building and will be available shortly

# When there will be official upstream release fixing this?

We are working on preparing the release tarball as of this moment and the fixed 
tarballs will be published as soon as they are ready.

Sorry for any inconvenience this might have caused, we wish we would have 
caught this during our extensive testing, but alas we didn’t.

Thanks,
Ondrej
