mythmessage - what I learned

based on reading lots of posts, I thought I would summarize for any others interested:
1. The wiki is wrong - the default port in use my mythmessage is 6948 (not 6549)
2. The wiki is wrong - mythmessage won't listen to broadcasts, only packets directed just to that IP
3. The wiki is incomplete - the timeout for messages ONLY applies while playback is in progress. Otherwise, timeout is ignored and an OK button appears and the message stays on screen, and queue up.

And of interest...messages queue up on screen! So if you plan to use mythmessage interface to show CID info, you may find 100 dialog boxes queued up all waiting for an OK click...when you return to the frontend

yuk....

hopefully future versions will allot the timeouw to work even if a menu is onscreen!

I actually got it working in mythutil by specifying a single IP as the broadcast (strange):

mythutil --message --message_text "Hi There" --timeout 5 -v --bcastaddr 172.31.254.58

but I really want it to work using netcat so I don't have to compile mythutil on other systems which send the message. Any advice on how to make netcat work with this?

Oh...and the 5 second timeout has no effect...I still have to click OK each time onscreen. Hopefully there is a workaround for that too...

Subject: [mythtv-users] MythUtil - can't show a message on frontend

I am trying to show a message onscreen on my .25 frontend. I have tried using mythutil and netcat, but neither works. The syntax (and output) is below of both methods. Can anyone tell me what I'm missing?

Thanks!

I have never used mythutil message (and probably never will; my
use of MythTV is different than yours), but if the wiki is wrong
based on your knowledge, *please* update it with the correct
information. It is the only way to make it better for the next
person.

Thanks.

People don't seem to get that about wikis. OTOH if you find a whole
lot appears to be wrong it would pay to check others' experience.
Posting to the list saying "X is wrong on the wiki" isn't the way i
would do it, I'd tend to say "in my experience X seems to be wrong, my
findings are Z. Before I change the wiki do others have the same
experience?"

Broadcasts work fine for me. I use this in several of my home
automation scripts.

mythutil --message --message_text $message --timeout 5 --bcastaddr
192.168.1.255

My network is 192.168.1.0 w/ 255.255.255.0 as the subnet mask.

I can receive the same message on many frontends.

This is true. I do wish it would timeout as well. I have seen many
references to this on the list though. All of my frontends suspend to
ram so I don't usually have frontends running when they aren't being
used so it hasn't been an issue. This definitely should be noted on the
wiki

I just went through this myself. I tweaked my cid script to query each fe
and only send the message if playback was in progress to avoid messages
piling up on the other fes.

Could you share that script? I have held off on integrating CID info with
my FreePBX / MythTV setup because of the timeout issue. Then I'll just have
to figure out how to have FreePBX execute a script when a call comes in.

If you use the CallerIDSuperfecta module from nerdvittles you can make
it hit custom URLs and things like that when a call comes in. It is a
really nice module.

I have tried that. My PHP being non-existent, I have been unable to produce
a php page that execute mythutil to send on the CID to my frontends.

Since it is just referencing a URL, there is no reason that you need to
use PHP. You can write a shell script and have it do what you want.
You will need to turn CGI scripts on and such like that. You will also
need to get a copy of proccgi most likely.

Thanks for the pointers, it's helped. I have configured Apache for CGI
scripts and they're working. I wrote a very basic script to get started...

#!/bin/sh
echo "Content-type: text/html\n"
echo ""
echo "Hello World"
mythutil --message --message_text "Hi There" --timeout 5 -v --bcastaddr
192.168.25.32

If I execute this script directly (./caller-id), it works and the message
pops up on my 192.168.25.32 frontend. However, if I browse to
http://apache-server/cgi-bin/caller-id.sh my browser displays the "Hello
World" message, but nothing pops up on my 192.168.25.32 front end. This is
the same issue I had trying to do it as a php page.

Any suggestions?

Hi;

Add 2>&1 >> /tmp/cgi-test.out to the mythutil command line.
Then check see whats in /tmp/cgi-test.out. Maybe $PATH
doesn't include mythutil's directory.

Thanks Bill, there was some text about unable to find Home folder in the
output of the web page that got me on the right path. I added a line to my
script before the mythutil call and it's working....

# set home directory
export HOME=/home/sharris

Is there a better way to do this?

HOME=$HOME mythutil --message ...

It is usually a good idea to explicitly set the path to the mythutil
program. You could do something like this

prog=/path/to/mythutil

$prog --message --message_text "Hi There" --timeout 5 -v --bcastaddr
192.168.25.32
