We have published an article about the 'Slave DNS' Plesk extension in our blog. Parallels does not provide technical support services for this Plesk extension. The extension is intended to serve as example of how certain technical tasks can be accomplished.

I have setup Slave DNS using plesk 12. But it is not creating the zone in slave server. I could see log in /var/log/messages of slave server. But DNS zone is not creating. I have followed the KB "[URL] ...." for setup.
Nov 4 13:31:25 li456-187 named[16905]: received control channel command 'addzone testnith.com { type slave; file "testnith.com"; masters { 108.161.131.59; }; };'

I am using the Slave DNS manager and I'm getting the following error in /var/log/messages on the slave server when the master/plesk tries to send change notifications.received notify for zone 'example.com': not authoritative
The domain is pointing to ns1.mydomain.com and ns2.mydomain.com, the domains zone on the master has both of these as NS records. And the SOA record lists ns1.mydomain.com as the primary authoritative nameserver.The zone has not been set on the slave server, what would be the cause here?
Slaves named.conf
bbb.bbb.bb.bbb = Slave IP
aaa.aa.aa.aaa = Master/Plesk
Code:
options {
listen-on port 53 { 127.0.0.1; bbb.bbb.bb.bbb; };
listen-on-v6 port 53 { ::1; };

I've got a Plesk 12 server with the "Slave DNS Manager" extension installed.I've also got a CentOS 7 server that I would like to set up as a slave DNS server.I've installed BIND on the slave server and opened ports 53 and 953.I've followed the instructions on this page but I can't seem to get a link between the two servers: URL....
I've also tried the config that the Plesk panel provides like the case in this thread, I get the same results: URL....
I am setting up slave DNS servers using bind 9.8 on CentOS 6. I have followed the procedure here successfully: [URL] ....
The problem is that even if I see something like the following in named.run on the slave server (which implies the rndc connection worked):
received control channel command 'addzone xxxxxxxx.com { type slave; file "xxxxxxxx.com"; masters { x.x.x.x; }; };'
received control channel command 'refresh xxxxxxxx.com'
received control channel command 'addzone xxxxxxxx.com { type slave; file "xxxxxxxx.com"; masters { x.x.x.x; }; };'
I still cannot query any entries for that zone from the slave DNS server:
$ dig @y.y.y.y xxxxxxxx.com
; <<>> DiG 9.8.3-P1 <<>> @y.y.y.y xxxxxxxx.com
; (1 server found)
;; global options: +cmd
[Code] .....
I also do not see any zone files created anywhere on the slave server.
I've setup Bind 9.10.1 on a windows server as a slave DNS server. I've installed the Slave DNS Manager on Plesk 12 for Linux and setup configuration.
New zones are added ok so authentication en communication is working perfectly. But when I delete a zone in Plesk, the zoneconfig file doesn't get deleted on the windows server. I can see the windows eventlog saying "received control channel command 'delzone <domain>'" where <domain> is the zone I deleted. But after that noting. And I see errors after a while because of bind trying to transfer the deleted zone again. The zonefile isn't deleted from c: amedzones...
I have setup bind in centos 6.5 and then edited /etc/named.conf and added the lines
The extension produced but I am getting the following error when restarting the bind service
Error in named configuration:
/etc/named.conf:2: unknown option '...'
/etc/named.conf:14: unknown option '*'
/etc/named.conf:21: 'options' redefined near 'options'
The following code suggested by plesk slave dns manager extension
Code:
options {
...
allow-new-zones yes;
};
key "rndc-key-mainserver ip" {
[Code] .....
After I removed ... from the options now I get the following error :
/etc/named.conf:51: unknown key 'rndc-key'
I have recently started using the slave DNS manager in the Plesk extension library. I've found that even for DNS zones that are switched off in Plesk, failed sync/transfers still try to take place between the slave and master. Why is this so?
Shouldn't turning the DNS functionality off in Plesk remove the zone from the slave DNS server?
When a domains DNS functionality is turned off, it removed the zone info from the master, but no command is issued to remove it from the slave??
Domain that is trying to sync/transfer: example.com
Plesk/Master server: 111.11.11.111
Slave DNS: 222.222.22.222
Code:
May 6 08:51:39 ns2 named[1178]: zone example.com/IN: refresh: unexpected rcode (REFUSED) from master 111.11.11.111#53 (source 0.0.0.0#0)
May 6 08:51:39 ns2 named[1178]: zone example.com/IN: Transfer started.
May 6 08:51:40 ns2 named[1178]: transfer of 'example.com/IN' from 111.11.11.111#53: connected using 222.222.22.222#53166
[Code] ...
How are the records on slave DNS servers updated ? Does it use the settings in the SOA section of the zone files to determine how often slaves are updated ?
Code:
18 ; serial
14400 ; refresh (4 hours)
7200 ; retry (2 hours)
2419200 ; expire (4 weeks)
3600 ; minimum (1 hour)
Is there any way for master to push out notifications to slaves OR get slaves to update their DNS sooner.
The main reason for this is it seems adding an entry on the master (via the GUI) is taking ages to appear on the slave.
I have a Windows/Plesk installation (Windows DNS), what is the best way to make a slave DNS server?I have two more servers without Plesk, windows and linux, one of then could be my slave server, how to accomplish that?
View 1 Replies View RelatedI installed Route 53 extension to manage a slave DNS server but when a add or remove some domain the process does not complete, Plesk stays loading without finish domain creation.
When I disable the extension, Plesk create and remove domains without any problem.
What could be happening?
If I change DNS using Plesk Panel the DNS server does not send a notification to the slave server, however if I change DNS directly through the DNS Manager it does send the notifications. Looking around the only thing I can find is an old post [URL] .... I'm not sure if this is related.
View 7 Replies View RelatedI have a web application (PHP and ASP.NET editions) which is widely distributed. The common question from users is "why does your script lack cPanel (or Plesk) integration?"
Can anybody provide some guidelines of whether/how it's possible to develop a web app (PHP, ASP.NET) which will act as add-on to cPanel or Plesk, assuming that I will develop this integration using shared hosting account?
The docs for cPanel/Plesk I found so far assume you have a dedicated server with admin access to cPanel (or Plesk) and thus can do everything with the server during the development process. But can I perform development of cPanel/Plesk compatible applications having shared hosting account only? Or, maybe, some hosting providers enable the required functionality while others do not? If so, could anybody recommend such a provider from whom I can get an account and make my web app cPanel compatible?
I need to make the application at least installable by means of cPanel/Plesk, so that anybody could install it using cPanel/Plesk only and its icon would appear in the control panel just like other cPanel/Plesk-compatible apps do. Deeper integration (whatever it could mean) is planned but not for the time being.
The same question for Plesk.
Or, I have no other choice but to get two dedicated servers with cPanel and Plesk for my development purposes?

How to configure bind using WEBMIN as slave zone with [url]as master?
View 1 Replies View RelatedThis week I reached the pinnacle of all time greatest screw ups I've ever done with a web server in five years. During a routine upgrade, my server crashed and basically burned to the point that the technicians at Burst/Nocster felt it would be in my best interest to clear the server out and do a fresh restore.
Fortunately, I had the majorty of files and designs I've done on a safe backup. Unfortunately, the mysql database I had was not so fresh and recent. In there lies my big problem on an issue I really have not seen much information about.
We all know of the mysqldump command that can be used to backup databases and save a .sql file on the server. Its quick, easy, and relatively painless. The problem I have run into is
mysqldump --opt -u nqforum_braduser -p nqforum_nodqdb > /home/nqcom/backup.sql
This would be the command I'd use on my normal mysql dump. However, all of my files and past server information has been installed as a slave hard drive temporarily until I can gather everything I need. Therefore, the command above won't work because it is looking for this mysql database & user that does not exist on the new server. I currently have the slave hard drive path stored at
/mnt/olddrive/
So for example, to get to the website that would have that particular database
/mnt/olddrive/home/nqforum/
So my question for those who know anything about slave hard drives and mysql, how can I get a simple current backup of this database saved to a location, then of course once it is saved as a .sql file somewhere, I can simply run a mysql restore command in SSH to bring it back.
I'm not too experienced with this, so I'm hoping someone more enlightened here can help.
Scenario:
I'm trying to build a social network site geared towards old people. I'm using LAMP environment. I want to have 1 mysql master (writes) and 2 mysql slaves (reads). Two web servers will read from the 2 mysql slaves and write to the one mysql master.
Questions:
My concern is this: when a user posts a comment via the webserver, the comment is written to the mysql master. I would like for him/her to see the comment he posted right away so they don't think something failed or went wrong. I'm afraid that replication to the mysql slaves will take some time to sync all of the mysql databases together. How can I work around this? Or am I mistaken and this doesn't actually happen?
How fast is replication? How can I mitigate this delay in replication to show the user instant results of their submission.
The same thing can apply to uploading photos to a user's profile.
Is there any way to migrate a VPS from one HyperVM machine to another without the new machine being a slave or part of the same master as the other node? Maybe some kind of simple software that can copy it over? We have root access to the new node, and not the old one. We need to move 3 VPSs over. This is a personal favor for a friend, so I apologize for the lack of specific details. Long story short, he resells VPSs and needs to move hosts (again) as the one he is on turned crappy. He bought his own box @ LSN and wants to put these VPSs on there. It's currently set up as a HyperVM/OpenVZ box, same as the other box that's to be migrated *from*.
