Go to install

Recommended install, asks about prompt

Default route for normal installs. Clears old MOTD, disables uname banner and asks whether the shell prompt should be installed.

wget -qO- http://www.failurenetworks.net/failuremotd/install.sh | sudo env FN_CLEAR_ETC_MOTD=1 FN_DISABLE_UNAME=1 sh -s -- http://www.failurenetworks.net/failuremotd

Install MOTD + coloured prompt without asking

For machines where the FailureNetworks prompt should be installed automatically.

wget -qO- http://www.failurenetworks.net/failuremotd/install.sh | sudo env FN_CLEAR_ETC_MOTD=1 FN_DISABLE_UNAME=1 FN_INSTALL_SHELL_PROMPT=1 sh -s -- http://www.failurenetworks.net/failuremotd

Install MOTD only without asking

For servers where the login banner should change, but the user shell prompt should stay untouched.

wget -qO- http://www.failurenetworks.net/failuremotd/install.sh | sudo env FN_CLEAR_ETC_MOTD=1 FN_DISABLE_UNAME=1 FN_INSTALL_SHELL_PROMPT=0 sh -s -- http://www.failurenetworks.net/failuremotd

Clean upgrade

Removes old assets and prompt blocks before installing the current package again from the live path.

wget -qO /tmp/fn-uninstall.sh http://www.failurenetworks.net/failuremotd/uninstall.sh
sudo env FN_REMOVE_ASSETS=1 FN_REMOVE_PROMPT=1 FN_PROMPT_ALL_USERS=1 sh /tmp/fn-uninstall.sh

wget -qO- http://www.failurenetworks.net/failuremotd/install.sh | sudo env FN_CLEAR_ETC_MOTD=1 FN_DISABLE_UNAME=1 sh -s -- http://www.failurenetworks.net/failuremotd

Uninstall everything

Removes the installed MOTD assets and FailureNetworks prompt blocks.

wget -qO /tmp/fn-uninstall.sh http://www.failurenetworks.net/failuremotd/uninstall.sh
sudo env FN_REMOVE_ASSETS=1 FN_REMOVE_PROMPT=1 FN_PROMPT_ALL_USERS=1 sh /tmp/fn-uninstall.sh

Emergency disable

Quick remote disable path if a login shell needs the MOTD hook moved aside fast.

ssh USER@HOST 'sudo mv /etc/profile.d/00-failurenetworks-logo.sh /etc/profile.d/00-failurenetworks-logo.sh.disabled 2>/dev/null || true'

Verify web files

Checks that the live install script and the important hosted MOTD assets are reachable.

wget -qO- http://www.failurenetworks.net/failuremotd/install.sh | grep 'VERSION='
wget --spider -S http://www.failurenetworks.net/failuremotd/scripts/show-failure-networks-logo.sh
wget --spider -S http://www.failurenetworks.net/failuremotd/assets/fn-security-notice-v13.ans
