Bind upgrade producing errors on pfsense 2.5 upgrade

No that did not work for me.

I do not have problems with the working of BIND, I can start/stop BIND and BIND is running fine. The problem I still experience is a very slow start after reboot (5 minutes) and a very slow package reinstall (also 5 minutes) This is because of the "rndc: connect failed: 127.0.0.1#8953: timed out" X 5 times. After the fifth timeout BIND starts (after 5 minutes or so) succesfully. This is an issue for me because packages like PFBlockerNG services, VMWare Guest services start only after BIND succesfully started. So it takes a long time for all the services being up & running after a restart/reboot

@matthijs I have the same issue since I am also running the resolver, even worse I have many zones in bind and it takes up to 40mn to have all my services up.

matthijs

Hi NetGate, is this going to be fixed anytime in the near future ?
We have this issue since the 2.5.0 release

@matthijs

I presume 'bind' is a package with a non-Netgate-member maintainer. Like pfBlockerNG Suricata, postfix etc etc.
As such, it's done by people like 'you' and 'me' : pfSense users.

I couldn't find who is maintaining it right now (but didn't really looked more then 30 seconds neither ;) )

Find him send send him a PM ?

edit : check also the redmine tickets : there are 10 tickets open for BIND.

matthijs

@gertjan Ok thanks for the info, I did not know that :-)

de0xyrib0se

@matthijs was bind turned off when you tried to remove the journal files?

matthijs

@de0xyrib0se
No, first thing I did was raise my SOA serial number for my (master) zones (with a number higher than in the last .jnl zone update) I use the date serial format yyyymmddnn)
after that I logged in the PFSense host with ssh, went to /cf/named/etc/namedb/master/mymastername/
rm *.jnl
and then restarted bind
I think it is not related with my issue

My problem with bind (I think) is during statup/boot and also with install/reinstall package it is trying to connect to rndc 127.0.0.1#8953 for some reason, but it is not running at that very moment, resulting in the rndc: connect failed: 127.0.0.1#8953: timed out message (and it is trying 5 times or so taking a long time)

Gertjan

This :

@matthijs said in Bind upgrade producing errors on pfsense 2.5 upgrade:

rm *.jnl
and then restarted bind

These jnl are database-lookalike files, binary format en opened by bind permanently.
You can't 'delete' them while bind9 has them open for writing.

is a major no go.

If the rm and restart had to be done (I doubt) I would do it like this :
( old fashioned debain service handling )

service bind9 stop

Now I edit zone files, config files, whatever.

When done, I check my config and zone files :

named-checkconf -z

When no errors and all looke dandy :

service bind9 start

Btw : when I need to update a zone, for example : I want to change the SOA :

oot@ns311465:~# rndc freeze test-domaine.fr
root@ns311465:~# nano /etc/bind/zones/db.test-domaine.fr
root@ns311465:~# rndc reload test-domaine.fr
zone reload queued
root@ns311465:~# rndc thaw  test-domaine.fr
A zone reload and thaw was started.
Check the logs to see the result.

No need to restart bind, no journal file issues.

Btw : journal files exists if the zone files are modified by other means as the admin.
For example : when the zone contains info that is update using RFC 2136.
Or when the zone is signed for DNSSEC.
Simple zones do have dot jnl and dot jbk files.

Btw : I'm using the somewhat older

BIND 9.9.5-9+deb8u19-Debian (Extended Support Version)

Shut down bind (command is listed above) and then do the rm, you cannot remove the files when it has a read lock on them. Restart bind afterwards and it will rebuild the journal files automatically.

This is what I did and it worked like a charm.

@de0xyrib0se , @Gertjan,

Thanks for your reply and suggestion. I did exactly as you described (I probably also stopped bind before, I forgot to mention that) Your suggestion did not solve my "rndc: connect failed: 127.0.0.1#8953: timed out message" during statup/boot and package install/reinstall.

rndc tries to connect to 127.0.0.1#8953 (during startup/boot and package install/reinstall) at a moment it is not running (hence the timeout). After bind is started it is running with no problems. Also rndc runs perfectly without errors AFTER bind is started.

If bind (named) is not running, rndc cannot contact it, hence the

rndc tries to connect to 127.0.0.1#8953

error.

If named is running, there error won't show (because rndc can now contact named on port 8953).

Again : running unbound and bind on the same device is something I wouldn't advice to do.

matthijs

@gertjan

"If bind (named) is not running, rndc cannot contact it, hence the rndc tries to connect to 127.0.0.1#8953"

So why is rndc trying to connect to named (during reboot) when named it is not started yet ? And why is there no problem at all as soon as named is started ?

"Again : running unbound and bind on the same device is something I wouldn't advice to do."

Why not, I got unbound and named running on seperated interfaces and separated ports

Gertjan

@matthijs said in Bind upgrade producing errors on pfsense 2.5 upgrade:

As long as the control port, yours are 8953 for bind, and 853 for unbound, are not conflicting - thus not the case, and you 'bind' unbound to "interface 1" and named to "interface 2" they could co-exist.
The control port are normally only bound to 127.0.0.1 or ::1.

@matthijs said in Bind upgrade producing errors on pfsense 2.5 upgrade:

So why is rndc trying to connect to named (during reboot) when named it is not started yet ?

I'm not using bind, the pfSense package, myself.
I don't know why and when rndc is used.
Check the logs to see if bind (named) is already started when this happens.

@matthijs said in Bind upgrade producing errors on pfsense 2.5 upgrade:

And why is there no problem at all as soon as named is started ?

rndc is a program that controls the behaviour of bind (named) during run time.
Like unbound-control for unbound.

rndc won't produce error messages f named is not running.
And it complains if it does.

The real question is (for me) why is rndc executed if named isn't running yet ?

Btw : like a web server, or mail server, a DNS resolver + domain server like bind isn't really a service that can be made accessible with a GUI. There are just to many settings, options and different cases.
You wind up using the config files.
Take note : I use bind (named) a lot, as master domain server and several slaves, for all my domain names, DNSSEC stuff. The pfSEnse acme package works perfect using RFC2136, something bind supports very well. But I use it on my web/mail/whatever servers, all dedicated servers on the Internet, not my local firewall.
Again, this my my opinion of course.

I did a complete reinstall of PFsense 2.5.2 and restored my last configuration.

It did not reinstall all of the packages incl bind/named automatically after the first reboot
I got the following notice in the upper right corner

General
Package named does not exist in current pfSense version and it has been removed. @ 2021-10-11 13:44:20
Package reinstall process finished successfully @ 2021-10-11 13:44:45

It did automatically reinstall all the other packages

I use ACME with DNS-NSUpdate method on the PFSense box which works great
I need the ACME certificates on de PFSense box because I also use HA-Proxy SSL ofloading for a number of websites.

Everything was working fine with PFsense 4.5.x, I first encountered the bind issues after the upgrade to 2.5.0

Gertjan

Ah, ok.

Executing custom_php_resync_config_command()...rndc: connect failed: 127.0.0.1#8953: timed out

When installed, bind (named) can't run right away. It probably needs some setup first.
And if it runs right away during the install, as the default is 'bind ports (853, 53) to all interfaces, this would clasch with unbound right from the start.

Why rndc is used during install : I can't tell.
Maybe related to this :

BIND requires configuration of rndc, including a "secret"
key.  The easiest, and most secure way to configure rndc is
to run 'rndc-confgen -a' to generate the proper conf file,
with a new random key, and appropriate file permissions.

But again, like nearly any other pfSense, package, the service won't run as it needs a proper set up first.
What happens when you install bind, and while it's loading, you stop the unbound service.
bind (named) will probably start as it can use all the ports/interfaces it needs.
After that, you fine tune bind, and restart it.
Then you can start unbound also.

matthijs

@gertjan
rndc-confgen -a creates default config in /usr/local/etc/namedb while de pfSense uses a chroot environment for bind/named. (in /cf/named/etc/named/)

Like I said bind/named was working fine in psSense 4.5.x without issues

The message/notice after a full new psSense install and restore the configuration is also not good

"General
Package named does not exist in current pfSense version and it has been removed. @ 2021-10-11 13:44:20
Package reinstall process finished successfully @ 2021-10-11 13:44:45"

I hope the issues get fixed soon
