CentOS 5 Server :: SOA On Secondary Slave Not Returning Anything?
Apr 12, 2010
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 just installed ubuntu, this is my first time with it so excuse my ignorance regarding it. My issue is that ubuntu does not show my secondary slave seagate hdd .. it only shows and installs on my western digital master primary one. I need to have access to my slave drive because it has data on it which i wanna use. My secondary slave shows up in my windows and bios just fine. So what gives?
I'm trying to add my xp drive to the boot menu but I'm having some trouble with it. I've been going over dozens of topics on many forums and I still can't get it to work (I'm new to linux/ubuntu btw).
Ok, so, I have Ubuntu 10.04 on the main drive (primary master) and xp on a second drive (secondary slave) and from what I've read sec. slave is hd3. I added the lines I found in another thread (here I think) but when I tried to boot xp it said the drive didn't exist.
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.
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 situation where I have two DNS servers - a BIND one for our Unix hosts and a Windows Server DNS one for the Exchange and other Windows hosts. I set up the BIND server to slave from the Windows one, which it seems to do just fine.
Windows DNS has entries like "_gc._tcp.domain.local" in it, which are needed for domain logins, etc.
However, when I try to use nslookup on those entries, it fails when querying the BIND server. When I do a domain transfer with dig, I get all the answers I expect.
This failure means that the Windows boxes can't query the BIND server for the answers they need. By default, from DHCP, it is the BIND server they get, so that's a big problem. If I manually switch their DNS to the Windows server, it works perfectly.
I don't know how configure or how explain what i want to do .... i have one server with dhcpd and dns name cache (also squid as a transparent proxy and iptables), this works fine but logs show this code...
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.
I have a problem with secondary IP on CentOS 5.5 With network configuration like this
[Code]...
So I try to add secondary IP
[Code]...
If i try to add another secondary IP (for ex. xx.231.17.166) xx.231.17.166 *can!* be pinging from global network And if i try to add xx.231.17.147 in network configuration script and reboot server (so this address becomes primary) all works fine. So i need to set xx.231.17.147 as secondary IP, but i can't do it..
how can i teste that my slave dns work better;knowing that my primary dns is in an other machine .i tried to dig the slave ;i have the response but when i halt my primary dns ,i couldn't dig the slave dns.

I am studying RHEL myself, not clear with following topics How to configure DNS slave server in RHEL 5 Whether named.rfc1912.zones file entry can be included in named.conf itslef,if not What is following entry means inside named.conf file
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?
OS :: Debian Lennyldap :: Openldap (newest one/get from apt-get)replication :: yes (on different machine)secure :: yes (tls)hi there i got problem on slave ldapwhat i am trying to do now is to have machine authenticate at slave ldapwhen master ldap die. So i stop slapd service at master ldap and try to authen. As a result of it, the prompt for login appears to fill in username but with the correct password couldn't make login successfully. I have checked at log file but there is any authen log of that login I wonder if it doesn't direct authen to slave ldap server. Here is my client config ::
I installed fedora lastnight, but any addresses I type in the field is returning server error, but if I type the IP address it will work, I reinstalled Fedora 11 about 3 times, samething.
Everything worked fine until very recently, and without apparently ANY change to the settings on the server, a secondary IP that was assigned to my server won't work anymore..Any IP attached to the same server works fine.. So in my case, the problematic IP is 213.8.155.67. The other IP (213.8.155.42) works without any problem.How would I go about troubleshooting this?

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 options .....

The maillog is showing errors which i am pasting here for the convienance.
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.
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

We have hosting all the domains to one ISP domain and we want a secondary MX record. Is it possible to have a secondary MX record to another ISP so that if our internet is down we don't lose any email. the first ISP are not providing any secondary MX records
I have a number of CentOS servers with latest 5.xI have 3 nameservers in the resolv.conf files. All 3 nameservers test out fine when checking for domain lookups.I'm having some trouble with ns1 and shut it down.l None of the CentOS machines fail over to the ns2 & ns3 entries. Basically everything stops resolving even though the other 2 nameservers are alive and well.
