Linux dns service help-Linux Enterprise Application-Linux server application information. The following is a detailed description. Hello everyone, I want to implement dns resolution host name rac-scan.localdomain for three different ip addresses, it should be round-robin algorithm, each time in order of three different ip addresses, not random resolution.
The test environment is as follows:
The ip address of the host fedora14 is dhcp and used as the dns server. It is not clear whether a fixed ip address is required as a dns. Or can I specify the dns server ip address on the client?
Two notebook interfaces, the current wireless network, dhcp
Cat/etc/hosts
127.0.0.1localhost.localdomainlocalhost
: 1localhost. localdomainlocalhost6

Install the software as follows:
Bind-9.7.4-2.P1.fc14.x86_64
Bind-libs-9.7.4-2.P1.fc14.x86_64
Bind-utils-9.7.4-2.P1.fc14.x86_64
(Bind-chroot is not installed, and the installation is even dizzy)

Named configuration file
Options {
Listen-on port 53 {any ;};
Listen-on-v6 port 53 {: 1 ;};
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 ";
Allow-query {any ;};
Recursion yes;

Dnssec-enable yes;
Dnssec-validation yes;
Dnssec-lookaside auto;

/* Path to isc dlv key */
Bindkeys-file "/etc/named. iscdlv. key ";

Managed-keys-directory "/var/named/dynamic ";
};

Logging {
Channel default_debug {
File "data/named. run ";
Severity dynamic;
};
};

Zone "." IN {
Type hint;
File "named. ca ";
};

Include "/etc/named. rfc1912.zones ";
Include "/etc/named. root. key ";

# Zone "rac-scan" IN {
# Type Master;
# File "rac-scan.localdomain ";
#};

The last few lines are added by myself, and the named service cannot start.

[Root @ localhost Desktop] # cat/var/named/rac-scan.localdomain
$ TTL 86400
@ In soa localdomain. root (
42; serial (d. adams)
3 H; refresh
15 M; retry
1 W; expiry
1D); minimum
In ns localdomain.
Rac-scan in a 192.168.1.131
Rac-scan in a 192.168.1.132
Rac-scan in a 192.168.1.133

I want to achieve the following:
Enable two other virtual machines on the host machine. Use the host machine's dns service, and assign three IP addresses according to rac-scan. The three ip addresses allocated by the VM and the host and rac-scan are in the same network segment. How can this problem be solved? After two days, even the services cannot get up ...... Hope you have a finger. Thank you.
