Hi. I have tried to do everything like here setting hostname,domainname and static IP address but it did not help me and i still have issue with resolving DNS names.

 

[root@node1 etc]# ping 192.168.226.128

Non-authoritative answer:

Name:   oracle.com

Address: 137.254.120.50

[root@node1 etc]#

 

 

my resolv.conf file is:

 

[root@node1 etc]# cat /etc/resolv.conf

# Generated by NetworkManager

domain localdomain

search localdomain node.com

nameserver 192.168.226.2

[root@node1 etc]#

 

and

[root@node1 etc]# cat /etc/hosts

127.0.0.1   localhost.localdomain localhost

192.168.226.128  node1.node.com node1

[root@node1 etc]#

 

 

[root@node1 etc]# hostname -a

node1

[root@node1 etc]# hostname -d

node.com

[root@node1 etc]# hostname

node1.node.com

 

 

DNS configuration RGhost — файлообменник

 

[root@node1 etc]# rpm -q bind

package bind is not installed

 

but:

 

[root@node1 etc]# rpm -q  bind-utils

bind-utils-9.8.2-0.17.rc1.0.2.el6.x86_64

 

and:

 

[root@node1 etc]# ps -ef | grep -i bind

rpc       1947     1  0 Dec21 ?        00:00:00 rpcbind

nobody    2831     1  0 Dec21 ?        00:00:00 /usr/sbin/dnsmasq --strict-order --local=// --domain-needed --pid-file=/var/run/libvirt/network/default.pid --conf-file= --except-interface lo --bind-interfaces --listen-address 192.168.122.1 --dhcp-range 192.168.122.2,192.168.122.254 --dhcp-leasefile=/var/lib/libvirt/dnsmasq/default.leases --dhcp-lease-max=253 --dhcp-no-override --dhcp-hostsfile=/var/lib/libvirt/dnsmasq/default.hostsfile --addn-hosts=/var/lib/libvirt/dnsmasq/default.addnhosts

root      8237 19846  0 04:18 pts/2    00:00:00 grep -i bind

 

so i can not understand why dns is not able to resolve ip or whole name for mentioned hostname?
