connection between nodes on wisc cluster

[Noah Watkins]

I spun up a 2 node cluster with a link between the nodes. Across the 10.10.1 network I cannot ping the other node.

nwatkins@node-0:~$ ping 10.10.1.1

PING 10.10.1.1 (10.10.1.1) 56(84) bytes of data.

From 10.10.1.2 icmp_seq=1 Destination Host Unreachable

From 10.10.1.2 icmp_seq=2 Destination Host Unreachable

From 10.10.1.2 icmp_seq=3 Destination Host Unreachable

^C

Same from the other node. The public network works.

We had some earlier troubles with some NIC firmware not passing ARP
traffic, but those nodes look to have gotten the necessary firmware
updates.

It also doesn't look like those particular nodes are in use by your
experiment anymore. Were you able to work it out on your own?

Thanks,
Brian
