Parallels Virtualization and Automation Software

SYMPTOMS

New nameserver based on RedHat EL 5/CentOS 5/FedoraCore 5/FedoraCore 6 OS template registered in HSPcomplete system have Error status after installation, password was entered correctly.

 

CAUSE

Bind caching-nameserver configuration file on new RedHat-based distributions (RedHat EL 5/CentOS 5/FedoraCore 5/FedoraCore 6) is now by default /etc/named.caching-nameserver.conf instead of /etc/named.conf as it was in previous OS versions.

RESOLUTION

For new nameservers based on RedHat EL 5/CentOS 5/FedoraCore 5/FedoraCore 6 distributions the following changes should be additionally performed before registration in HSPcomplete system:

• /usr/sbin/rndc utility on the nameserver have no executive bit set for all:
  
# ls -l /usr/sbin/rndc
-rwxr-x--- 1 root root 21812 Oct 16 09:26 /usr/sbin/rndc
  
  It is required to allow members of named group to execute this utility:
  # chgrp named /usr/sbin/rndc
• new nameserver configuration file inside the nameserver VE should be created as /etc/named.conf with the following content:
  
  
options {
        listen-on port 53 { 127.0.0.1; any; };
        directory       "/var/named";
        dump-file       "/var/named/data/cache_dump.db";
        statistics-file "/var/named/data/named_stats.txt";
        memstatistics-file "/var/named/data/named_mem_stats.txt";
        query-source    port 53;
        query-source-v6 port 53;
        allow-query     { any; };
        allow-transfer { none; };
};
logging {
        channel default_debug {
                file "data/named.run";
                severity dynamic;
        };
};
include "/etc/rndc.key";
controls {
        inet 127.0.0.1 port 953 allow { localhost; };
       };
view localhost_resolver {
        match-clients      { localhost; };
        match-destinations { localhost; };
        recursion yes;
        include "/etc/named.rfc1912.zones";
};
view "external" {
        match-clients      { any; };
        match-destinations { any; };
        recursion yes;

        include "/var/named/named.zones";
};

• permissions for /etc/named.conf file should be changed in the following way:
  
  # chmod 640 /etc/named.conf
# chown root.named /etc/named.conf
