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'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.
Here's my menu.lst file code...
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 about to perform a fresh ubuntu install, and i was wondering if anyone knew whether installing on the slave or master drive mattered. i know if you're installing on the same drives it's slightly faster for ubuntu to be installed first, but that doesn't seem to be the case since i have two separate drives

I installed bind 9 sucessfully, and create many zones on its.
I want to biuld 1 slave server but i have problem :
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

View 3 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

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'm setting up a Master and Slave OpenLDAP (ver. 2.4.25) use Replication method following {URL]. When I used slapdcat (slapdcat -l master_dump.ldif), I got a message:

# Directives needed to implement policy:
# access to dn.base="" by * read
# access to dn.base="cn=Subschema" by * read
# access to *

# if no access controls are present, the default policy allows anyone and everyone to read anything but restricts updates to rootdn. (e.g., "access to * by * read") .....
My Slave slapd.conf is similar configuration to the Master Server...
In our Server they configure Master / Slave Dns using SSL authentication while tranfering the zone files, i dont have much idea about ssl authentication for Dns, how it will works

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'm managing a residential network. Each flat is its own subnet, and can only communicate with the other flats through a router (i.e. no broadcast). 95% of these 300 subnets only contains windows computers (from lambda users).
My final goal is to be able to browse the entire network from any computer.
I set up a samba server acting as a wins server, and every computer is aware of it because it is registered in the dhcp. So name resolution is working fine for everyone.
The same samba server is set to be the "Domain master browser":
workgroup = WORKGROUP
wins support = yes
prefered master = yes
local master = yes
domain master = yes
os level = 65
When I browse the network (using "net view" or "browstat view"), I can only see the servers which are in the same subnet as the domain master browser.
Now, when in a subnet the computers arrange themselves to find a "local master browser", the only visible computers are the one in that subnet.
What I don't understand is why all the local masters don't synchronize their lists with the domain master.
So, to sum up, every subnet get the following behaviour:
-if a local master is elected, the only visible computers are the one in the same subnet.
-if no local master is elected, the only visible computers are the one in the subnet of the domain master.
-if I add another samba, configured as a local master winning all elections, then the magic is working and the lists are synchronized.
What is expected:
-every computer can see all the computer from all the subnets.

I have a load balancer with 2 web servers behind it. The web servers rsync with cloud storage to update their apache directories 1 time every hour. Apache is just running php pages that pull/push data to a DB so they dont need to be updated that often. However I need to figure out how to implement a Master/Master MySQL setup to have my web servers point to for the PHP stuff. I need to implement it without having a single point of failure. The Load balancers are useless for failover as they only detect availability based on Ping request. So putting a master/master setup behind a Load Balancer is out. what is the best way to setup the master/master mysql in a HA setup without the use of a load balancer provided by the host?
View 2 Replies View RelatedCurrently I am running Ubuntu 9.10 on an older P4 system with EIDE harddrives. My primary HD has a WinXP installation and GRUB. Ubuntu is installed on the secondary HD.
I am happy enough running Ubuntu that I would like to remove my WinXP disk, move the disk with Ubuntu on it to be the primary boot drive, and then install a new drive as the secondary.
However when I tried to simply move the drive with Ubuntu on it from the secondary to the primary EIDE position the system would not boot. I assume that this is because there is no boot loader currently on that drive.
how do I put GRUB on the Ubuntu drive so that it can become the boot drive? Or is there some other way to accomplish what I am after without having to reinstall Ubuntu?
