IPv6 issues virtualmin

Hi There,

I currently set-up Virtualmin with 2 Webmin slave servers. They are all configured with BIND DNS.

Since yesterday morning they are acting a bit weird, since they try to connect with ipv6, over ipv4 and ipv6. Any idea how to disable ipv6 for BIND sync?

Internet is telling me to edit the OPTIONS parameter in /etc/sysconfig/named Sad thing is, i cannot find the OPTIONS= line.

Can anyone help me out?

Hi Justin, Here is the contents of my /etc/default/bind9. I run Virtualmin version 5.02.gpl on Ubuntu Linux 14.04.1. Yours might be in a different location. Typing "locate bind9 | less" might give some clues, but I fear the config file goes by other on other operating systems.

# run resolvconf?
RESOLVCONF=yes

# startup options for the server
# OPTIONS="-4 -u bind"  # to use ipv4 only
# OPTIONS="-6 -u bind"  # to use ipv6 only
OPTIONS="-u bind"       # to use ipv4 and ipv6

The trick is that you can have only one of the three last lines un-commented.

You will find it is sort of hard to completely turn off ipv6, so other services may still be bothersome and try using it.

Thanks for oyur reply. I reinstalled the environment with Ubuntu and now i'm still facing the same issue. IPv4 gets resovled with IPv6.

Do i need to set RESOLVCONF to yes? Mine is set to no at the moment.

AFAIK, "YES" is the default setting. It makes named resolve names on the local system - which is very good!. But, I run a stand-alone web server. You might need "NO" in a server cluster. Perhaps one of your servers has YES while the others are NO. NO will prevent /etc/init.d/bind9 from adding 127.0.0.1 as a nameserver address when named is started. If everything works, leave it as is! :)

I tested the resolve with no and yes, but this does not change anything. Also the boot option is set to ipv4 only Also disable ipv6 completely and it still tries to sync over ipv6....

Any ideas what could be wrong? Really weird.

How do I either unsubscribe from emails totally unrelated to my question or alternatively tame the avalanche of unrelated emails by configuring a daily digest ??

I've installed virtualmin in FreeBSD but it doesn't show as a module and obviously doesn't appear to be working. I cannot locate any documentation specifically for FreeBSD and the linux documentation doesn't apply, Would someone kindly direct me to relevant information ??

Actually I did that a week ago and have yet to receive even one response and consequently I was wondering if the system was completely borked

Well posting a question in the correct area got me zilch after a week and the one in the wrong area got me several responses even if they were unfriendly ones. Make what you will of that.

Any ideas what could be wrong? Really weird. It's a clean install
