<p>Hi Jordan, thank you for the suggestion to try msmtp directly as
user icecast2</p>
<p>First I try as user kpovdjs (me):<br>
</p>
<pre>kpovdjs@Icecast-Pi:~/bin $ echo "hello there username." | msmtp -a gmail <a class="moz-txt-link-abbreviated" href="mailto:thatjackelliott@kpov.org">thatjackelliott@kpov.org</a></pre>
<p>This does send the email. <br>
</p>
<p>Now su to user icecast2</p>
<pre>icecast2@Icecast-Pi:/home/kpovdjs/bin$ echo "hello there username." | msmtp -a gmail <a class="moz-txt-link-abbreviated" href="mailto:thatjackelliott@kpov.org">thatjackelliott@kpov.org</a>
msmtp: account gmail not found: no configuration file available</pre>
<p>Interesting. For user kpovdjs, msmtp finds account information in
/home/kpovdjs/.msmtprc<br>
</p>
<p>But as user icecast2, there is no .msmtprc file in /home/icecast2
<br>
</p>
<p>In fact, there is no icecast2 folder in /home</p>
<p>So I create /home/icecast2</p>
<p>I copy my user .msmtprc to /home/icecast2</p>
<pre>icecast2@Icecast-Pi:/home/kpovdjs$ ls -la /home/icecast2
total 12
drwxr-xr-x 2 icecast2 root 4096 Sep 20 10:57 .
drwxr-xr-x 5 root root 4096 Sep 20 10:51 ..
-rw-r--r-- 1 icecast2 root 332 Sep 20 10:57 .msmtprc
</pre>
<p>Now I try again:</p>
<pre>icecast2@Icecast-Pi:/home/kpovdjs$ echo "hello there username." | msmtp -a gmail <a class="moz-txt-link-abbreviated" href="mailto:thatjackelliott@kpov.org">thatjackelliott@kpov.org</a>
msmtp: account gmail not found: no configuration file available</pre>
<p>If msmtp cannot find its rc file in /home/icecast2, then maybe
there is a way to specify the location. <br>

Hi Jack,<br>
<br>
Have you tried, as the icecast2 user, interactively using the
msmtp command instead of with your script? Try this, it will
narrow down the variables. Also, check to see if your iceast2 user
has the required group membership(s), if any, to send mail from
that machine.<br>
<br>
<br>
Cheers,<br>

<p>Okay my amateur bash script is badly written and I will clean
it up. <br>
</p>
<p>But I don't think my clumsy scripting explains why I can run
the script as user kpovdjs, but not as user icecast2?</p>
<p>It uses /usr/bin/msptp and <br>
</p>
<pre>kpovdjs@Icecast-Pi:~/bin $ ls -l /usr/bin/msmtp
-rwxr-xr-x 1 root root 83848 Jun 19 2014 /usr/bin/msmtp</pre>
<p>So that isn't a problem. <br>
</p>
<p>And the script:</p>
<pre>kpovdjs@Icecast-Pi:~/bin $ ls -l email_onconnect.sh
-rwxrwxrwx 1 kpovdjs kpovdjs 422 Sep 20 10:08 email_onconnect.sh

<p>Yes, I have tried running the script as user kpovdjs and it
works. And the same command as user icecast2 does not work and
does not make an error message. <br>

<p>Thomas Zumbrunnen wonders about my mount point definition,
this is it:</p>

<pre class="moz-quote-pre" wrap="">Hi all,
I am still trying to debug this. Summary, I am using <on-connect> in
my icecast.xml to launch an email when a source-client connects.
Here is the line in icecast.xml:
<on-connect>/home/kpovdjs/bin/email_onconnect.sh</on-connect>
The problem is that this script doesn't do anything when icecast runs
it.
The script works if I run it as user kpovdjs (me). But if I su to
user icecast2, it does nothing.
"email_onconnect.sh" is:
#!/bin/bash

<pre class="moz-quote-pre" wrap="">Your printf is wrong here.
NEVER do something like: printf "bla $blubb bla\n";
ALWAYS do: printf "bla %s bla\n" "$blubb";
That is exactly why we use printf in the first place. This is the
reason it exists.
Also you can just pipe your output between the commands. No need for a
tempfile (which also adds many problems, from permissions to race
conditions).

It also does not send the email when I invoke it as user icecast2.
The "set -x" debug output is the same.
At this point it seems that this is not a icecast issue, per se, but
some sneaky subtle weird annoying little Linux thing. However, if
anyone here has an idea on how I might solve it, it would be very
much appreciated.

You could check Icecast's error.log to see if it reports a problem.
Other than that you really first need to establish that the script

Very cool, I haven't encountered the "set -x" debug flag before.
However, the output isn't as interesting as I hoped:

Okay now that I am user icecast2, let me see if the script I
want the Icecast server to run <on-connect> runs, so . . .
icecast2@icecast-Pi: $ ./email_onconnect.sh
and the prompt returns immediately, no error message, but no
email received. But if I su back to my_username and try the
script, it runs and an email is received.

This tells me that your script is not doing what it needs to do
as the Icecast user. Since you're doing it outside of Icecast,
it's not the <on-connect> or <on-disconnect> triggers that are
failing. It would be helpful if you could paste your script
(sensitive info like passwords removed) here.
Cheers,
Jordan
