View 1 Replies View RelatedI 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.

View 3 Replies View Relatedim 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 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 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.
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

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?

View 1 Replies View RelatedI am interested in setting up a webserver on a PC I have laying around...more for the experience and knowledge of learning it from scratch.

My question is, can I use this desktop I have to simply install the CentOS DVD torrent off their website, and start from there, with installing apache, and all the other items associated with a server environment to test/play around, or is there a difference and something I am missing with my plan to do this?

I checked the virtual mail account's home folder, and under the mydomain.com folder, I only see a folder for firstuser. I'd create one for testuser manually, but I don't know if that'll work since it seems to contain a particular folder structure of its own.
Is there some other command that I have to run? I don't recall having to do anything additional when setting up firstuser.
