[Dnsmasq-discuss] dnsmasq has started crashing rather frequently

[Chris Green]

I am running dnsmasq version 2.86 on xubuntu 22.04.  Just recently (i.e. in
the past few weeks) it has started crashing with a segfault.  The syslog has
the following:-

Sep  5 19:43:14 t470 dnsmasq[13183]: no servers found in 
/run/NetworkManager/no-stub-resolv.conf, will retry
...

'core-dump'.


It didn't used to crash like this.  I see that dnsmasq was moved from version
2.85 to version 2.86 at the end of July 2022, is there possibly a bug in 2.86
causing these crashes?

[Dnsmasq-discuss] DNSSEC Enable with Centos 7

[Michelangelo Lauria via Dnsmasq-discuss]

Hello, I need to use dnsmasq with “dnssec" enabled in a Centos 7 environment.
The yum repository lists dnsmasq v.2.76 available to install which I understand 
is outdated and seems to me it is without dnssec.
I have tried to compile from source but I am getting several errors of 
dependencies and don’t know how to create the service. 
Instead I can install and run as service dnsmasq from yum no problem, but it 
does not support dnssec. 
Can you suggest a repository to install the latest version (with dnssec) and/or 
provide guidance on compiling thsi software and enabling it to run as service ?

Thanks
