Server :: Local Master Browser Do Not Sync Their List With The Domain Master

Nov 13, 2009

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.

Server :: Setup Master / Master Mysql In HA Setup Without Use Of Load Balancer Provided By Host?

Mar 31, 2010

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?

General :: Master And Slave DNS Server Replication

Nov 29, 2010

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.

Apr 2, 2010

I have a Centos NIS server that is working fine with other linux clients. i need to have a Solaris 8 client bind to the NIS domain and found out that Sol8 does not support MD5 format passwords that the NIS master is generating. so i am trying to disable the MD5 encryption on the nis master and it does not seem to work. i run this command

authconfig --disablemd5 --enablenis --nisdomain=lab --updateall

and it restarts portmap and nis services ok. on the master server i then do a yppasswd username and a make passwd and it still uses the 34 char password format. what do i need to do to disable MD5 passwords in a centos nis server?

CentOS 5 Server :: DNS Not Replicating From Master To Slave?

Jan 27, 2010

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

CentOS 5 Server :: BIND Notify From Non-master?

Aug 26, 2011

I have setup two BIND9 servers as slaves for an internal Windows domain. I receive messages in my logs about a Windows server not being the master for the slave domain on BIND. I have placed the allow-notify statement in the global options section of named.conf, as well as setting the IP address in the masters section of the zone. I'm confused as to why I'm still getting this error message.

Server :: Distribute Securenets File From NIS Master To Slave?

Jan 25, 2011

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.

Server :: ProFTPD Master/Root User Can't Get Into All Folders

Mar 2, 2010

So, I wanted a master ftp user that could access all the folders for all the users. I did this by creating a second root user. I'm aware of all the security considerations, and if there's a better way to do this than creating a root user I'd really like to know it. That said, my issue is that my new root user is still unable in FTP to access folders owned by other users that aren't world readable. Note that this is ONLY when logging in via ftp. If I login through SSH I can access all folders without problem and without the need to sudo. So this is a true root user. Does anyone have an idea how I can fix the proftpd configuration to allow my root user access to ALL folders no matter the owner?

Server :: New Zone Entry In Master Not Getting Updated At Slave

Feb 19, 2011

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

Networking :: IPtables Rules For Master DNS Server To Allow Zone Transfer

Oct 24, 2010

I have set up a master DNS server at 192.168.50.9 and a slave DNS at 192.168.50.6. Both servers are BIND9.Machines are for testing/experimenting, hence the IP addresses. Initially, the zone transfer was blocked by the firewall on the master, as the slave uses randomly selected non-privileged ports for zone-transfer query. So, as far as I understand, there are two possible approaches:

1. Allow connections based on source, which should be
Code:
-A RH-Firewall-1-INPUT -p tcp -m state --state NEW,ESTABLISHED -s 192.168.50.6 --sport 1024:65535 --dport 53 -j ACCEPT
(and it works for me fine)

2. Allow ESTABLISHED and RELATED connections, which would be something like
Code:
-A RH-Firewall-1-INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
which was my initial idea but didn't work, but has inspired me to dig deeper into firewall configuration topics :).

Question: Does zone change notification message count for opening a dialog, or notification from master and slave zone update request are two absolutely separate actions? If the latter is true, that, of course, explains why option #2 didn't work.

Networking :: Setup Multiple FTP Servers With Distinct Data Sets With 1 Master FTP Server?

Aug 27, 2009

Faced with disk-bound issues on a FTP server with high traffic. Would like to set up multiple FTP server nodes with dedicated storage for each node where all FTP access is managed by a master FTP server. So, a user would FTP to a single externally visible IP address for the master FTP server and then get routed to the appropriate FTP node. Are the mutiple FTP nodes required or is there a better way of doing this? Perhaps only one FTP server is required and then each node would serve as a separate file server

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.

Like one time we got 56, other time 3 , other time 43.. like this.. We are sure that 97 logs are being forwarded. Checked the Rsyslog.config filer any filters and couldn't see any filter dropping them. When we run the tcpdump, we can see 97 connections, but logs are not there in specified location.
