Inclussion to init.d assistance

Hi all,

Am trying to have an email sent on start up advising that the system has been reset.
During the week the system reset itself and no email was received, below is an extract of the file /etc/init.d/sendmail . And I'm stumped to understand why the email wasn't sent.

Can anyone see why things didn't go to plan as I'd thought they would?

# SendMail startup/shutdown script.
case $1 in
        set -- `who -r`
        if [ "$9" = "S" ]               # run only during boot time
            if [ -x /usr/lib/sendmail ]
                if [ ! -f /etc/ ]
                        touch /etc/

                /bin/su root -c "/usr/lib/sendmail -bd -q1h" 2> /dev/null

                /bin/su root -c "mail -s'* EVEREST HAS BEEN REBOOTED *' \
                                 ops@????.com,dhoey@????   \
                                 < /---_stats/admin/reboot.notice "


        if [ -x /bin/ps -a -x /bin/kill ]
            # su root to set luid (required for systems with SECLUID set)
            pid=`su root -c "ps -e" \
                | sed -n -e '/ sendmail$/s/^ *\([1-9][0-9]*\) .*$/\1/p'`

            if [ -n "$pid" ]
                kill $pid

        echo "Usage: $0 {start|stop}" >&2

DOH !!

Just noticed that the email address ops@????.com was not complete ... missing the .au on the end.

Well, I've rebooted the server and sadly waited in vain - no email.

Can anyone suggest why this isn't happening?

Restore the system startup script to its original state. Create your own little script in init.d to send a mail message at reboot time. Link it into rc2.d and give it a high S number so that it is the last thing to run.

Thanks Perderabo, will try it when I come back into work tomorrow.

Forgot to set the script in init.d .

Set it up in /etc/rc2.d directly (S99xATIN#1 - sticks out like a sore thumb) and works a treat.

Still learning, but why include it into /etc/init.d and link it to the /etc/rc2.d directory - what are the benifits of doing that?

Most of the init scripts will have two links: a S.... to start up and a K.... to shut down the service. By copying a new script to, say, init.d/sendmail, you update both the startup and shutdown script at the same time. All you can do the update without knowing at which run level the service starts. Someone might have disabled sendmail by removing the S and K links, but you can still update the script because it's still in init.d. And if someone did that, (remove the S and K links), because the script still exists in init.d, it can be easily re-enabled. Mostly though, it's a standard of sorts and you shouldn't break a standard with a good reason.
