Server :: Slave DNS Server - To Act As Fail Over?
Sep 11, 2010
im running two name servers using bind9 in my infrastructure. both are identical distros ubuntu 10.04Both are also receiving updates from each other, so no worries there.The issue is, when the master name server goes down, the slave for some reason doesnt take over and act as a primary name server. Can someone please help me on how to enable this feature using bind9?What basically I want to happen is when the master server goes down, slave will take over the primary role till the master comes back online

I have set up a nis slave server on Fedora 14. It was set up on a laptop so that the user can log in when he is at home (no NFS, local home dir). However, whenever the eth0 is disconnected, ypbind fails.
I have tried the same setup on a RHEL 4 (configured it as a slave server) against the same master nis as on the Fedora 14. Disabling eth0 on it however does not fail ypbind.

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.

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?

I recently set up replication on a production server and some rows are not making it to the tables on the slave. After 3 days I can see 200+ entries (of 161,000~) that are on the master and not the slave. Logs under /var/log including mysqld.log, mysql.status, messages do not show any problem.I have already tried dropping the DB on the slave and setting up the replication again by doing a stop slave, set slave options such as were in the logging to start, drop table, restore the dump previously made by the master, start slave, but the issue persists.
I following the documentation on the MySQL site for setting up replication so I'm not sure why this is having issues.What can I do to investigate and fix this?

I 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 a secondary slave dns server setup, it has transferred all the records from the primary master.But when I run a few checks from outside using tools on the net it says:Tried to fetch SOA record for domain, but DNS server ns2.domain.com returned error code Refused.I disabled iptables, and tried again, same result. So I think it is something in the named.conf file? I appreciate any extra set of eyes on it. Just feel like I'm so close!

I 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.

I 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
Master Server Configuration

I am trying to setup Rocks Cluster on a Cluster containing 1 Master node and 23 slave nodes connected via a Switch. The master node's eth1 is connected to public IP and eth0 is connected to the slave nodes via the switch.
I was able to install the Rocks cluster on the machine, I configured the IP for master through DHCP. When I run the command 'insert-ethers' on the master node, it doesnot get me any slave nodes.
setting up the Rocks cluster on all the nodes?

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.

I am failing to log in on a NIS client server. I input the login name and takes long to bring password prompt. It then gives an error :Login timed out after 60 seconds. A boot message also appears : No NIS server found when it attempts to start ypbind.
I am stuck since I need to correct the NIS configuration on the server. How do I login then into the server.

At some point my Ubuntu 9.10 Desktop install has stopped being able to connect via ftp to servers. I have several servers that I have accounts to and I have several ftp clients installed on my system, including gftp, Filezilla, and command line ftp tools. None of them can connect to any of my servers.
Here it is from the command line:
> ftp mywebsite.com
ftp: connect: Connection refused
I can connect fine with my netbook running Ubuntu, only my desktop has this problem, and of course I use my desktop for development. Do I have a firewall running or something that's blocking my outgoing requests over port 21?

I have recently discovered the following: when I attempt to connect to any of our machines that are OpenSSH 5.x (Ubuntu 10 or OpenSuSE 11.x in our case) as one of the users defined in the NIS domain that fails. For instance, me (user bepstein) can SSH into all those machines but not SFTP.I can SFTP into those machines on the network that are OpenSSH 4.x, however (CentOS 5.3 - 5.4, OpenSUSE 10.3).As a user defined locally on the machine (in /etc/passwd ) I can connect via either SSH or SFTP even if the machine is OpenSSH 5.x.Some further discussion of that issue is available here: http:[url]....

I have a DNS server with 3 zonesone is dynamic with an associated reverse and one is static
Everything was fine until I added a single host in the staticzone then the server stopped resolving names in that zoneThe only way I could get it to work again was delete the whole zone and re enter the zone and hosts

New ubuntu desktop user here. I've been working with Ubuntu servers for over 3 yrs, using Windows as clients. I have OpenVPN running on an ubuntu 10.04 server, and it has worked well with Windows OpenVPN clients connecting. I took those same settings and applied them to this new install of Ubuntu 10.04 Desktop, and now openvpn seems to be failing when we get to the routes (I wrestled with the network-manager "secrets" issue for hours, but that works now).
I performed the following:
sudo openvpn --config fogbank-ny1.ovpn
--all is well, we're connecting/yay then *screech* FAIL--

I am using the suggested openvpn routes. If I connect from Windows (actually the .ovpn file is taken directly from the working windows machine).. all is well, routes work fine all traffic is routed thru the VPN -- same way it's worked for over a yar. I assume that this is what is causing networkmanager to fail as well. those logs indicate that it has connected to the vpn, but is probably stopping when it gets to routes.

I tried installing Ubuntu LTS 10.04 Server Edition 64 bit on one of my drives today...
The install completed fine until it went to reboot. Then it faills while initializing the graphics. It tries (a purple flash on the screen) then goes to a text based dump on the monitor.
Ubuntu LTS 10.04 Desktop Edition run great on this machine. I'm wondering if the Server Edition confused by multiple instances of a video card? This computer is SLI bridged:
Code:
Is the xorg or whatever video subsystem that the server edition uses different than Desktop Edition?
