Sorry, I made 2 mistakes

1. MAILC is the parameter you want to override, not MAIL
2. I didn't read your email well enough to see that you have already tried something similar.

What you did should have worked. Make sure you are modifying the configuration file that is actually being used. Also, if you haven't yet, you would have to restart xymon server to pick up that configuration change.

That happens because the messages have CR+LF line terminations, or have at least a few lines that have CR in them; this is causing Unix to treat those as binary instead of text content. In our system, I created a script that runs tr to get rid of those

#! /bin/bash

20130104 - glauber - get rid of CR in emails

exec /usr/bin/tr -d '\015' | /bin/mail "$@"

Then I set the MAIL parameter in xymonserver.cfg to point to this script instead of the actual mail application.

It works beautifully.

Xymon server is version 0.1.4, the client in this instance is BBWin 0.13 on a Server 2012 R2 system.

Occasionally, I am seeing xymon alarms with ATT00001.bin attachments instead of an actual message.

I already googled this, and applied the MAILC fix that I found to xymonserver.cfg, but it's still happening sometimes. I discovered some other bad characters that needed to be removed, so my tr command is set up to remove three characters:

For the xymond_alert module

MAILC="/usr/bin/tr -d '\\001\\004\\015' | mail" # Command used to send an e-mail with no subject #MAILC="mutt -x" # Command used to send an e-mail with no subject MAIL="$MAILC -s" # Command used to send an e-mail with a subject

Looking in the attachment that I just received, I can see hex 0D characters (carriage returns, octal 015) ... but the "tr" command that I implemented should have removed them.

Either there's a bug, or I am missing something simple. Can anyone help? I have not yet tried upgrading Xymon to the latest version.

Thanks, Shawn

I just saw that you used single quotes and double escapes

tr -d '\\001\\004\\015'

I think you need

tr -d '\001\004\015' or tr -d "\\001\\004\\015"

(and restart xymon after making the change)

I did nearly the same thing found here, except I provided multiple characters:

http://lists.xymon.com/archive/2013-March/037159.html

Now I have set it like this, I will try it.

MAILC="tr -d \"\\001\\004\\015\" | mail"

Note that running the following command while logged into the same machine over ssh strips out those three characters:

cat bad-characters | tr -d '\001\004\015' > filtered

The double backslashes in the xymon config weren't my idea (it was suggested by the email thread I found), and I also tried it with single backslashes.

The xymon service was restarted after every change.

Thanks, Shawn
