How to transfer all zone from master to slave server ?
I configured a master DNS server 192.168.2.10 working OK. After that I configure a DNS Slave Server (92.168.2.11)the initial replication worked fine. This is test environment for my certification. I see how the zones from my master are transferred
zones in Master
training.com.db
transferred zone to my slave when I started named service
sec.training.com.db
That's Ok but I added some IPs to resolve to my master zone
webserver IN A 192.168.2.30
fileserver IN A 192.168.2.31
I restart/reload named on master and after that I go to slave and restart/reload but zones wuth the new values are not replicated. How long does it take for slave to take the changes from master? how is the procedure manual or automatic? I see If I go to slave and delete sec.training.com and restart named the zone with the changes is transferred but that is very manual... I am including my DNS Configuration so you can take a look.
I have bind configured with Internal and External views, but the slave server is transferring only the Internal zone files for both Internal and External - a diff shows no difference, and the log shows the same serial number.What am I missing in the config so the slave server properly receives updates from the master for both views?
View 2 Replies View RelatedI have set up a master BIND DNS server with 2 slaves. All the services start up fine on all 3 servers, but zones and named.conf info is not being replicated. The 3 servers are tentatively installed on a Xen virtual server for testing purposes. All 3 servers are 64bit and installed with: -> CentOS release 5.4 (Final) - 2.6.18-164.10.1.el5xen -> BIND 9.3.6-P1-RedHat-9.3.6-4.P1.el5_4.2
All 3 servers are fully updated. All 3 servers have static IP addresses. The services on all 3 servers start up without any apparent issues. Master server: # /etc/init.d/named restart ; tail -f /var/log/messages

I have an EeePC 901, with a 4gb SSD and a 16gb SSD installed. Trying to get Natty installed and hit a few problems not least of which, that it won't fit on the 4gb drive! However in my BIOS setup under HDD config it says:
Secondary Master=4gb
Secondary Slave=16gb
I have no other devices attached. Why aren't they Primary? And I can't seem to switch them round.
Is there any possible to convert slave to master, and enable writing to db?
View 4 Replies View RelatedI have a large environment with many VLANs and NIS slaves serving the VLANs. Previously we have not used a securenets file (don't worry; we don't use NIS for passwords, just NFS maps), but I'd like to start. The number of NIS slaves makes it annoying to update a securenets file on each when we add a new VLAN. Is there a way to propagate the securenets file to each slave when I update it on the master?If not, I guess I can live with propagating the file once and only visiting new slaves when I build them, because in 99% of cases a NIS slave only serves its own subnet.
View 1 Replies View RelatedI have configured master and slave Bind servers. Everything works fine. But whenever I add a new zone entry at master server it is not getting updated at slave server in logs I see this error:
client 192.168.1.1#43428: view external: received notify for zone 'yourdomainname.com': not authoritative
At master server I do not see any error or warning message. This error clearly indicates that named.conf file does not have zone entry in it or domain name is wrong. While checking the named.conf file I see that the zone entry has not been updated at slave server. If I update it manually and reload named on slave then zone files (db files) are getting created without any issue and any modification at master server for the zone records are also getting updated. My concern is why zone record is not getting appended at slave server in named.conf file.
Is there anything I am missing in the configuration. I am pasting the steps which I have followed to configure my master and slave server:
Configure Bind as master and slave server
Install Bind on your server
yum install bind
OR
sudu apt-get install bind9
Generate RNDC Key using the command
rndc-confgen -a -k rndc-key
it will stored in /etc/rndc-key file
Master Server IP 192.168.0.1
Slave Server IP 192.168.1.1

I have servers which contain SATA disks and SAS disks. I was testing the speed of writing on these servers and I recognized that SAS 10.000 disks much more slowly than the SATA 7200. What do you think about this slowness? What are the reasons of this slowness?
I am giving the below rates (values) which I took from my test (from my comparisons between SAS 10.000 and SATA 7200);
dd if=/dev/zero of=bigfile.txt bs=1024 count=1000000 when this comment was run in SAS disk server, I took this output(10.000 rpm)

My Slave slapd.conf is similar configuration to the Master Server...
I need to perform instant filecopy between a pair of servers. Its loosely based on a master slave setup as we have ucarp floating a virtual IP between the two. services are on both boxes (tftp, apache). I'm happy with that, I now need a way to instantly sync files from set directories, as we could see problems if files have changed should the system fail over without being in sync
I know I could cron *1 but I don't want it running EVERY minute, in any case, if the change was within the last minute, then it wouldn't have the change anyway. I think it can be done with rsync daemons on box boxes, but I can't find a guide to to this. ATM the slave has been setup to accept rsync from the master, so I just need the config to have all changes on the master instantly replicated.
I started over combining the first parts of this guide: [URL]..ubuntu8.04 (Only the first few parts in terms of configuration and naming). Then I used this guide: [URL]..Surprisingly enough all steps worked.
1. Now I need to set up LAMP servers with MySQL master/slave replication and Apache rsync.
2. Next i need to add BIND to both my Load Balancers with master/slave backup and replication...
Are there any guides to look at to follow on these? Can tou point me to the right direction for BIND with replication.

Have someone used Linux heartbeat to send email when the Slave server becomes the Master? I've read I can configure the MailTo under.
But I really don't know how to do it. I basically need my primary server to send an email when it becomes inactive and all the activities are manage by the secondary node.

Trying to install SUSE on a perfectly working PC that was running Windows. Blew away all the partitions and formated the drives.When trying to install SUSE, Installer will not detect my two hard disks. Tried with version 10.x, 11.1 and 11.2, without success.My Mobo is a XFX GeForce 8209, and my SATA drives are both Seagates (1x120GB, 1x320GB). I've tried different SATA mode selection (i.e. SATA, AHCI, and RAID) without any success either.I've tried to look for SATA controller drivers for my Mobo, to try to load on Installer startup, but failed there too.
View 1 Replies View RelatedI have a Dell Studio XPS running openSUSE 11.2 with dual mirrored disks (using Dell's SATA controller). Does anyone know how I can set up automatic monitoring of the disks so that I will be informed if either fail? I think smartd might be what I need here. Is that correct? I added:
/dev/sda -a -d sat -m <my email>
/dev/sda -a -d sat -m <my email>
smartd is running, but how do I know that it will report what I need? I also have a client with a Dell PowderEdge SC440 with SAS 5/iR also running openSUSE 11.2. They also require automatic monitoring. There doesn't seem to be a SAS directive for smartd. I notice that the newer release says it does support SAS disk. I upgraded to 5.39. On restart (with DEVICESCAN as the directive) I get the following in /var/log/messages for my SAS RAID disk.

i currently try to mount 4 internal sata disks using hal on a server installation?
i did
apt-get install hal and copied a .fdi script to /usr/share/hal/fdi/policy/10osvendor/30-storage-all.fdi
as far is i understand now i need a hal/dbus client
gnome-volumen-manager seems to be one
apt-get install gnome-volume-manager
now im stuck there is no such executable like gnome-volumen-manager thus, how does it work? how can i start it? how do i know if and why the .fdi script works or fails?
since its a server edition and its purpose should be a very minimized server install i dont want a GUI like gnome fully installed
