Reopened tasks because of new sheepdog layout and add new machines to Octopus and get fiber optic network going with @andreag. IT recently upgraded the network switch, so we should have great interconnect between all nodes. We also need to work on user management and network storage.

Intermediate routing on Octopus08

default via 172.23.16.1 dev ens1f0np0
172.23.16.0/21 dev ens1f0np0 proto kernel scope link src 172.23.17.24
172.23.16.0/21 dev eno1 proto kernel scope link src 172.23.18.68
172.23.16.0/21 dev eno2 proto kernel scope link src 172.23.17.134

vim /etc/ssh/sshd_config systemctl reload ssh

The routing should be as on octopus01

default via 172.23.16.1 dev eno1
172.23.16.0/21 dev ens1f0np0 proto kernel scope link src 172.23.18.221
172.23.16.0/21 dev eno1 proto kernel scope link src 172.23.18.188

ip route

- Octopus01 uses eno1 172.23.18.188/21 gateway 172.23.16.1 (eno1: Link is up at 1000 Mbps) - Octopus02 uses eno1 172.23.17.63/21 gateway 172.23.16.1 (eno1: Link is up at 1000 Mbps) 172.23.x.x

• After the switch upgrade penguin2 NFS is not visible for octopus01. I disabled the mount in fstab
• On octopus01 disabled unattended upgrade script - we don't want kernel updates on this machine(!)
• Updated IP addresses in sshd_config
