SYMPTOMS
When attempting to install Oracle 12c Grid Infrastructure software on Linux, the following error occurs
WARNING: Error while copying directory /u01/app/12.1.0/grid with exclude file list '/u01/app/tmp/OraInstall2015-03-31_05-02-32PM/installExcludeFile.lst' to nodes 'node1, node2'. [PRCF-2010 : All connections to the remote nodes got refused. Cannot proceed with the file transfer. There has to be at least one remote node to send the installer files!
PRCF-2010 : All connections to the remote nodes got refused. Cannot proceed with the file transfer. There has to be at least one remote node to send the installer files!]
Refer to '/u01/app/oraInventory/logs/installActions2015-03-31_05-02-32PM.log' for details. You may fix the errors on the required remote nodes. Refer to the install guide for error recovery. Click 'Yes' if you want to proceed. Click 'No' to exit the install. Do you want to continue?
CAUSE
As part of GI software installation, binaries are copied to other nodes after starting ractrans process on the remote nodes. Connection attempts to ractrans port is being refused resulting in the installation failure on remote nodes as seen from the installation log below

The firewall is disabled and hence not the cause of the connections being refused
root@node1:~$ /etc/init.d/iptables status
iptables: Firewall is not running.
root@node1:~$ /etc/init.d/ip6tables status
ip6tables: Firewall is not running.
root@node2:~$ /etc/init.d/iptables status
iptables: Firewall is not running.
root@node2:~$ /etc/init.d/ip6tables status
ip6tables: Firewall is not running.
SOLUTION
The issue is caused by the kernel parameter net.ipv6.bindv6only being set to 1 as seen below
grid@node1:~> sysctl net.ipv6.bindv6only
net.ipv6.bindv6only = 1
grid@node1:~>
The solution is to set net.ipv6.bindv6only to 0 and install the Grid Infrastructure software
node1:~ # sysctl net.ipv6.bindv6only=0
net.ipv6.bindv6only = 0
node1:~ #
