Default MyDNS Stack Smashing ubuntu 9.10 64

Hi,

I'm seeing this in my syslog:

Code:
Mar 12 14:31:19 inferno mydns[5031]: *** stack smashing detected ***: /usr/local/sbin/mydns terminated
Mar 12 14:31:19 inferno mydns[4125]: pid 5031 exited due to signal 6
Mar 12 14:31:19 inferno mydns[4125]: Server pid 5031 died
I've redownloaded and re-made, but same results.

Thanks, Dant

Not shure what the error is, but as alternative you can use BIND now instead of mydns with ispconfig 3.0.2. (if its a new installation we are talking about here) It should be enough then to remove mydns and install bind with:

apt-get -y install bind9 dnsutils

and then install ispconfig 3.0.2

Yes, I am going to move to bind as well. Haven't gotten around to it yet because of all the work involved (lots of DNS entries that I need to overhaul). Anyway, this message is to confirm that I have the same error with mydns... and when there is no working dns on my box means that a lot of processes run significantly slower. So I recommend everyone with these problems to step over to bind.

Thanks till for adding bind support

Default Fix for stack smashing in MyDNS-NG 1.2.8.27

I really dislike the solution to switch back to bind9. So I searched for a solution and I found it.

For fixing this problem, apply this patch, posted on the Mantis bugtracker of MyDNS-NG. It's a bug in the current MyDNS-NG 1.2.8.27 version.
http://bugs.mydns-ng.com/bug_view_ad....php?bug_id=62

- Download latest version of MyDNS-NG (1.2.8.27)
- Extract archive
- apply the patch, or use VIM to modify 2 lines the file src/mydns/udp.c
- ./configure
- make
- stop the running MyDNS (/etc/init.d/mydns stop)
- make install
- start MyDNS (/etc/init.d/mydns start)

After applying this patch I'm able to answer UDP-queries in IPv6 and there's no stack smashing any more. I'm using 2 servers (Ubuntu 10.04 x64 and 9.04 x64) and this patch works.

For those who having .nl-domains, you can use the SIDN DNS-check (https://www.sidn.nl/over-nl/aanvraag...ent/dns-check/) to verify the usage.

@till: I hope MyDNS will still be available in the upcoming versions of ISPconfig3.

There are no plans to abandon MyDNS.
