ibping: iberror: failed: can't resolve destination port 0x002590ffff90579c
4 how to test this nodes can communicate with each other
set each with /etc/network/interfaces like
auto ib0
iface ib0 inet static
address 192.168.2.10-80 #from node01 to node08
netmask 255.255.255.0
post-up echo connected > /sys/class/net/ib0/mode
post-up /sbin/ifconfig $IFACE mtu 65520
gateway 192.168.2.215
