(Notify on SSH login (or other event))

This little script is called by the PAM daemon whenever there is a successful event in SSH, it ignores my own personal events, because I log in and out frequently, and don't want to hear my phone that much, just get rid of the first check if that's an issue.

#!/usr/bin/bash
# ntfy-ssh-login.sh
# This works with PAM, and appended to the bottom of /etc/pam.d/sshd;
# # This should send an alert whenever anyone logs in;
# session optional pam_exec.so /etc/pam-scripts/ntfy-ssh-login.sh
 
# No login alerts for me...
[ ${PAM_USER} == "xyzzy" ] && exit
 
echo "SSH event on Tiny: User ${PAM_USER}, ${PAM_TYPE} from ${PAM_RHOST}" \
  | mailx -s "SSH Alert" -r "Doom dude <xyzzy@cyli.org>" 5135551111@tmomail.net
