[SOLVED]Getting S.M.A.R.T smartd Local Emails and Desktop Notification

LacrimasProfundere · 2025-02-19 00:49:01

Hello, I hope everyone is doing well.

Intention is to get a desktop notification popup on Plasma (Wayland) when a SMART error is detected, and an email into /var/spool/mail. I seem to have something wrong with my current configuration, having attempted to follow the wiki.

smartd.conf:

DEVICESCAN -a -o on -S on -n standby,q -s (S/../.././02|L/../../6/03) -m lacrimas@localhost -M exec /usr/local/bin/smartdnotify

/usr/local/bin/smartdnotify:

#!/bin/sh

# Send Email
echo "$SMARTD_MESSAGE" | mail -s "$SMARTD_FAILTYPE" "$SMARTD_ADDRESS"

# Desktop Notification
sudo -u lacrimas DISPLAY=:0 DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/lacrimas/bus notify-send "S.M.A.R.T Error ($SMARTD_FAILTYPE)" "$SMARTD_MESSAGE" --icon=dialog-warning -u critical

I haven't set this service up before, I apologize if I'm missing something obvious - Please let me know if any more info would be helpful. If anyone has any ideas, I'd appreciate it - thank you!

https://wiki.archlinux.org/title/S.M.A. … management
Daemon is running?

Manual device scan works?
/usr/local/bin/smartdnotify is executable?
Manual execution of /usr/local/bin/smartdnotify works?

"DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/lacrimas/bus" isn't canonical, try "DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/1000/bus" or even better: import the environment from a relevant process, see https://gist.github.com/AladW/de1c5676d93d05a5a0e1 for a pattern

I updated my syntax to reflect the /run/user/1000 you suggested and that seems to show improvement and work for the desktop notification - Thank you. I was also able to clear the "mail command not found" error by just installing s-nail and sendmail.

A little odd now (probably a syntax/config issue in smartd.conf) that the service shows as fail to start, but I still receive a desktop SMART status alert when it attempts to run. My smartd.conf line now reads:

DEVICESCAN -a -o on -S on -n standby,q -s (S/../.././02|L/../../6/03) -m lacrimas -M exec /usr/local/bin/smartdnotify

smartdnotify now reads:

#!/bin/sh

# Send Email
echo "$SMARTD_MESSAGE" | mail -s "$SMARTD_FAILTYPE" lacrimas

# Desktop Notification
sudo -u lacrimas DISPLAY=:0 DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/1000/bus notify-send "S.M.A.R.T Error ($SMARTD_FAILTYPE)" "$SMARTD_MESSAGE" --icon=dialog-warning -u critical

Showing improvement, just trying to figure out what's up with the mail or causing the daemon to crash now. Basically just trying to get a "you have mail" message when opening a terminal to alert me (in addition to the desktop notification that's already working).
Thank you very much.

Edit: I noticed my /etc/hosts file didn't have a reference to 127.0.0.1 so I added:

127.0.0.1    localhost.localdomain localhost DesktopPC
127.0.1.1    DesktopPC

I then noticed that the sendmail service was complaining about "cannot open /etc/mail/local-host-names", which didn't exist on my system so I copied my /etc/hosts file to that directory and renamed it, which seems to have cleared that error, but am now presented to another from sendmail:

Have to step away for a bit but will keep playing around with this. Not sure what procmail is yet or why these resources seem to be missing from sendmail.

Simply installing procmail resolved the above issue. Restarted the sendmail service and then smartd, and alerts now seem to be sending properly.

Last question if someone can look over my .zshrc to see if I have it set correctly to check for unread mail ('autoload checkmail' on the fourth line), I'd like to get a notice/message when I open the console. Just not sure if I have the placement/order correct, when I restart the smartd service I get one message after it starts "You have new mail", but it's just that single message - If I close the terminal and reopen a new one I don't get a mail message in console.

HISTFILE=~/.histfile
HISTSIZE=10000
SAVEHIST=10000
autoload checkmail
bindkey -e
#zstyle ':autocomplete:*' list-lines 0
#source /usr/share/zsh/plugins/zsh-autocomplete/zsh-autocomplete.plugin.zsh

source /usr/share/zsh/plugins/zsh-autosuggestions/zsh-autosuggestions.zsh
# End of lines configured by zsh-newuser-install
# The following lines were added by compinstall
zstyle :compinstall filename '/home/lacrimas/.zshrc'

autoload -Uz compinit
compinit
# End of lines added by compinstall
eval "$(starship init zsh)"
#alias ls='ls --color=auto'
alias ls='exa'
alias dir='dir --color=auto'
alias vdir='vdir --color=auto'
alias grep='grep --color=auto'
alias fgrep='fgrep --color=auto'
alias egrep='egrep --color=auto'
alias ll='ls -l'
alias la='ls -A'
alias l='ls -CF'
alias update='yay -Syu && flatpak update'
alias clean='yay -Scc && yay -Sc && yay -Qtdq | yay -Rns -'
alias virt='virsh net-start default'
alias errs='sudo journalctl -b -p err|less'

export PF_INFO="ascii title os kernel de shell uptime pkgs memory"
source /usr/share/zsh/plugins/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh

Also, is it redundant to have both the

DEVICESCAN -m lacrimas

line for mailing in my smartd.conf, as well as the

echo "$SMARTD_MESSAGE" | mail -s "$SMARTD_FAILTYPE" lacrimas

? Would it be trying to send an email for each of those lines?

You don't need a full blown MTA for local mails, esp. from anything that runs as root and can write files everywhere.
They're just text files in a special directory.
See eg https://unix.stackexchange.com/question … y-for-cron for ideas.

Then see /usr/share/zsh/functions/Misc/checkmail or https://github.com/zsh-users/zsh/blob/3 … ckmail#L24
It checks whether the mail file has been modified since it's last access - if at any point it gets opened for reading, this will no longer be true, but the test itself should™ not cause such.

is it redundant to have both

Most likely yes, depend on whether "-m" works in your setup (which is likely)
