Hi Folks -

I have 2 instances of Xymon running (one internal to my network and one external). We have decided we want to set up the ability to ack over email. This is very easily set up (already did it on the internal version), except for one small detail, email from BOTH comes from xymon at mydomain.com. This means that replying to this address can only go to one or both. Both kind of stinks, as it means one system will be getting bad ack's all the time (and then xymond will go yellow). I'd like to set the email sender on the external instance to something different, but can't seem to find it anywhere in any of the configs. I looked through alerts.cfg and the man page and nothing stood out to me.

Is this possible?

Thanks! Skadz

Shouldn't this be the mail agent not the xymon server?

In sendmail, that would be Dj. In postfix, mydomain(?) or myhostname.

I guess for postfix it looks like it would be myorigin. Which is either mydomain or myhostname. In your case, you'd want the myhostname.

Ok, I guess I didn't make what I wanted very obvious :)

The domain isn't the part I want to change, I want to change the user it's sending as :)

So, I would like to have

xymon at mydomain.com for the Internal system

and

xymonext at mydomain.com for the external system.

I guess right now it's just using the user who runs the xymon processes, but was hoping this was something configurable, so I could make the different instances send as different users (so then I could set up replies to go to the correct host)

So change the userid that runs xymon. /etc/passwd and shadow.

I can't read if the 2 instances are on the same host or different.

If they are different just make a mail alias in the external host. For sendmail it is /etc/mail/aliases Xymon xymonext at domain.com<mailto:xymonext at domain.com> Then run newaliases

If they're on the same host 2 different xymon users should do the trick.

For sendmail it is /etc/mail/aliases

The aliases file only maps incoming mail (recipient address), not outgoing (sender address).

Postfix can do sender address mapping (see "man generic" and the ADDRESS_REWRITING_README), but if it's on the same server then you won't have a way of selecting one instance from another (unless they're running as different users).

However there are other ways to achieve what you want. If you're using "nail" as your mail client (mail -V), you can define options such as "from" and "replyto" in .mailrc. Maybe like this:

set from=sender at add.ress

Or you could change "MAILC" in xymonserver.cfg and add an "-r" parameter, such as:

MAILC="mail -r sender at add.ress"

I actually do this for every alert - in my case the from addresses are not real email addresses. There are several reasons why I went this route - one was to change the sender to be the hostname of the server in trouble. The 2nd and most important to me was to have a full "TO" and "CC" list so that whomever started working on a problem could easily "reply-all" and let everyone know they were working on the problem.

For each alert I run an external script (a portion of it is below) which sets up the email and then calls a perl script which then does the actual sending of the email. Yes, there are probably better ways to do this. I have been doing it this way for years and it has worked out extremely well for us. There is a lot more to the scripts then what I have below but this is the relevant portion. I have also added the relevant portion of the perl script that does the email farther down.

/bin/echo -E "

On call person paged: ${PAGED}

Alert Active Since: ${ACTIVE} (Duration of Alert ${ALERTTIME})

Please respond with a \"reply-all\" to this message if you will be taking corrective action. It is critical to communicate to others of your intentions. Ignoring these alerts is not an option.

You may use the link below to \"acknowledge\" the alert if the alert is being investigated. Do not \"acknowledge\" an alert for more than 60 minutes.

http://`hostname`.domain.com/xymon-cgi/bb-ack.sh Next to the appropriate system alert enter in the blank boxes: - Time in minutes to ignore. - Brief description. - Click send.

SCRIPTNAME - $SCRIPTNAME BBHOSTNAME - $BBHOSTNAME BBHOSTSVC - $BBHOSTSVC MACHIP - $MACHIP BBSVCNAME - $BBSVCNAME BBALPHAMSG - $BBALPHAMSG

If this message does not require any action by support on any occasion please send an email to xymongod at domain.com so that we may ignore this message in the future. By doing so we can reduce Xymon spam and increase the chance of receiving only useful and pertinent alerts.

" >$BBHOME/server/tmp/bb_email.txt.$$ $BBHOME/server/ext/pg/email.pl $$ "Xymon - CRIT $BBHOSTSVC $BBCOLORLEVEL" $BBHOSTNAME $SCRIPTNAME

    use MIME::Lite;
    use Net::SMTP;


    # Create the initial text of the message
    my $mime_msg = MIME::Lite->new(
            From => $fromhost,
            To   => @TO2,
            Cc   => @CC2,
            'Reply-To' => @TO2,
            Subject => $subject,
            Type => 'text/plain',
            Data => $email
    )
    or die "Error creating MIME body: $!\n";

    my $message_body = $mime_msg->body_as_string();

    MIME::Lite->send('smtp', localhost);
    $mime_msg->send() or die "Error sending message: $!\n";
