amtm Email notification when there are updates?

[LaMpiR]

Hi good people.

I have managed to successfully edit my email settings, but I don't know if such thing is possible, that I get an email notification when there is an update to scripts which I am running? Instead of manually having to log in and check for updates with amtm.

Thank you very much in advance.

Yes, although it is a little confusing. At the moment you have to install Diversion, and then within its settings you can ask for a firmware update notification. That sends a weekly email if there is an update to the firmware, amtm, diversion, any of the installed scripts, or any entware packages. It would make sense for this to be in amtm.

 

[LaMpiR]

Thank you for the info. The thing is, I don't need or use diversion :/

 

[elorimer]

Yes. Well, install diversion, then go into /opt/share/diversion/file and copy update-notification to /jffs/scripts. chmod 755 it so it will run. Try it to make sure it runs, then make a chron out of it. That will give you an email if there is an update.

Then uninstall diversion.

Hi!

Currently running asus-wrt merlin 384.13_10 on asus RT-AC3200

I did try your solution;
did install standard diversion 4.2.1 thru amtm 3.2.1
but I cannot find the /opt/var/share directory

also, I try to find, without success, the mentionned update-notification script under /jffs or the entware directory

Can you help ?

Thanks

 

[elorimer]

but I cannot find the /opt/var/share directory

Oops, sorry: /opt/share/diversion/file. Corrected my post.

The update-notification script gets installed in that directory. I just suggested copying it to /jffs because it would get deleted when diversion is uninstalled.

 

[itibi]

wow!
this is a fast reply. I am impressed. thanks

Hmm. I wonder if I have this as a hangover from an earlier install, like years ago.

Here it is; you could create the file in /jffs, chmod it and see if it runs.

Again, thank you for your reply

When running, it sent me the following email:

Hey there!
A new stable Asuswrt-Merlin firmware is available for your asus router at 192.168.1.1.
Installed version: 384.13_10
Latest available stable version: 384_13_10
...cut...

As you can see, it wrongly state that there is a newer version of merlin!!

Also, by taking a look at the script, it does not seems to check for update to
"firmware, amtm, diversion, any of the installed scripts, or any entware packages."

Maybe another script ?

Thanks

 

[itibi]

I had a similar script with contains:

VERS=$(nvram get webs_state_info | sed -E "s/.*([0-9]{3})_([0-9_]+?).*/\1.\2/")
ROUTER_IP=$(nvram get lan_ipaddr)
ROUTER_NAME=$(nvram get computer_name)
CUR_VERS=$(nvram get buildno)_$(nvram get extendno)
if [ "$CUR_VERS" != "$VERS" ] ; then
...cut...

Two things. The update email for amtm, diversion, etc. is diversion, specifically /opt/share/diversion/file/update.div. I don't know what happens if you run that without diversion installed.

Second, yes, I see when I run it I too get the "_" in place of the "." that triggers the update notice. I suppose you could get a weekly email and just ignore the spurious ones, or you could correct it, or you could run diversion.

@thelonelycoder, I'm making a hash of this mostly because it's been years since I first dug into this. Are you planning on moving this to amtm, or did you already?

 

[thelonelycoder]

Gents, the amtm send email when updates are available is in the planning.

 

[Jeffrey Young]

I whipped this script up a few years ago to check for script updates. I add a cron job to run the script everyday at 1000.

#!/bin/sh

readonly MAILFILE="/tmp/update_file.txt"
readonly AMTMCHECKFILE="/tmp/amtm-tpu-check"

if [ -f $AMTMCHECKFILE ]; then rm $AMTMCHECKFILE; fi

amtm tpu

UPDATE="No"

if [ -f $AMTMCHECKFILE ] || [ "$UPDATE" = "Yes" ]; then
    echo "The following updates have been reported by AMTM/Cake-QoS" > $MAILFILE
    echo "" >> $MAILFILE
    if [ -f $AMTMCHECKFILE ]; then
        cat $AMTMCHECKFILE >> $MAILFILE
    fi

    if [ "$UPDATE" = "Yes" ]; then   
        echo "Updates to Cake-QoS are available" >> $MAILFILE
    fi

    echo "" >> $MAILFILE
    echo "Check for updates done on $(date -R)" >> $MAILFILE
    
    if [ -f $AMTMCHECKFILE ]; then rm $AMTMCHECKFILE; fi
    
    /jffs/addons/young/smail.sh $MAILFILE "AMTM: Script Updates are available"
fi

smail.sh is my general purpose script that I use to email me when required.

 

[Jeffrey Young]

And this is my smail.sh script. I use it as a general purpose email script. Called for a variety of reasons. Looking forward to the @thelonelycoder implementation.

#!/bin/sh

# Send mail alert to administrator
#
# usage:
#    smail.sh text_body subject_line <recipients>

FROM="Sender Email"
AUTH="UserID"
PASS="GMAIL APP PASSWORD"
FROMNAME="Sender Long Name"

if ! [ $# -ge 2 ] && [ $# -le 3 ]
then
    printf "Not enough Arguments\n\n"
    printf "Usage: smail.sh <email_body> <subject_line> <address>\n\n"
    exit
fi

if ! [ -e $1 ]
then
    printf "File %s does not exit\n\n" $1
    exit
fi

if [ $# -eq 3 ]; then
    TO=$3
else
    TO="default email address to send to"
fi

echo "Subject: "$2 >/tmp/mail.txt
echo "From: $FROMNAME <$FROM>" >>/tmp/mail.txt
echo "Date:  $(date -R)" >>/tmp/mail.txt

cat $1 >>/tmp/mail.txt

echo "" >>/tmp/mail.txt

cat /tmp/mail.txt | /usr/sbin/sendmail  \
    -H "exec openssl s_client -quiet \
    -starttls smtp \
    -connect smtp.gmail.com:587  \
    -no_ssl3 -no_tls1" \
    -f "$FROM" -au"$AUTH" -ap"$PASS" "$TO" -v

rm /tmp/mail.txt

@thelonelycoder You also have my +1 vote for this implementation. Thanks in advance.
