We have problem to communicate with a number of windows hosts from a CentOS 6.9 host.
The Set is like below,
All nodes are in the same subnet, including the CentOS node,
From the windows side, there is a Management node configured using Active directory, there can be a number of hosts configured under this management node.
In the CentOS box, this Management node ip is configured in the etc/resolv.conf as below
Code: Select all
options timeout:1 attempts:1
nameserver IDM04MG1.IDM04.iyntax.net # hostname of the MG node
nameserver 192.168.59.132 # IP of the MG node
now from the, CentOS box its possible to communicate to all the nodes, those are coming under this particular MG node... No issue here.
But when we have to communicate to more than one set up, where the configuration is similar, its not happening,
That is in the etc/resolv.conf
Code: Select all
options timeout:1 attempts:1
nameserver IDM04MG1.IDM04.iyntax.net # hostname of the First MG node
nameserver 192.168.59.132 # IP of the First MG node
nameserver SHDMG1.SHD.iyntax.net # hostname of the second MG node
nameserver 192.168.59.156 # IP of the second MG node
But when its comes to the second one (SHDMG1.SHD.iyntax.net), its not at all possible to communicate,
Code: Select all
ping SHDMG1.SHD.iyntax.net # Fails
If I change the order as below
Code: Select all
options timeout:1 attempts:1
nameserver SHDMG1.SHD.iyntax.net # hostname of the First MG node
nameserver 192.168.59.156 # IP of the First MG node
nameserver IDM04MG1.IDM04.iyntax.net # hostname of the second MG node
nameserver 192.168.59.132 # IP of the Second MG node
its only possible to establish communication with the SHDMG1.SHD.iyntax.net node (ping SHDMG1.SHD.iyntax.net works) and the nodes coming under that.
But not with the second one, I'm stuck at the moment with it, Please help me.
