Changes to Bionic Nodes
26 May 2020
Host Key Change for rhino02 and rhino03
Configured ssh to provide the same host-key across all rhino-zero nodes. This will cause an error if you already have the key in place (i.e. have already connected to these hosts). It will raise an error like “DNS Spoofing Detected”.
ssh-keygen -R <hostname> will remove the key from the local database
New Local Packages
New packages “agrep” and “python-requests” have been installed.
Remove MOTD Messages for Unattended Upgrades
Spurious messages from the unattended-upgrades process have been removed from the MOTD
Local bionic mirror updated with latest changes from Canonical
Checkpointing utility “criu” has been updated from 3.13 to 3.48

Fixes to csh/tcsh Logins
Errors in the Lmod login files would raise error messages and result in a malfunctioning Lmod environment. These fixes address those problems and should restore Lmod functionality to users using those shells
We are applying the latest set of updated pacakges to the Bionic distribution. As this is an LTS release we expect that this will only fix bugs- there isn’t any new functionality introduced by these changes.
Note that this may take 24-36 hours to fully apply over the environment and doesn’t include kernel updates.
This change will also add automatic updating of OS packages.
We are updating Lmod to version 8.3 from the current 7.8. A full changelog is available here, but the most significant change for the community is the “extended default” matching of modules.
chromium-browser(on rhino nodes)
Fixed mail relay settings to allow nodes to send email
Disable ecryptfs Unwrap
Disabled the PAM settings to disable unwrap of ecryptfs directories at login. Users with ecryptfs volumes will need to manually unwrap.
