Linux-Blog 3.0

LiveJournal user suppressingfire pointed out that 11.0.0.1 isn't a private network address. My first reaction was that it didn't matter, since it was just for cluster interconnect. Still, best to keep things by the book, so we'll change it to keep it in side the 10 network.

# ifdown eth1

Then edit the /etc/network/interfaces file so the eth1 section now says:

# The cluster interconnect interface
auto eth1
iface eth1 inet static
address 10.1.0.1
netmask 255.255.255.0
broadcast 10.1.0.255

then bring the interface back up:

# ifup eth1

In the TruCluster world, we used to have a configuration option to totally block anything coming from the memory channel cards (the cluster interconnect) from getting out onto the outside network. I don't know for sure whether OpenSSI has such an option, so better safe than sorry.
