[Xymon] DAT attachments?

[Novosielski, Ryan]

At least on Solaris' mailx command, you can set the from address with -r if I'm not mistaken.

Interesting info to file away though as I'm sure down the road our Solaris will be replaced by RHEL.

Same issue here.  I configured this (plus nail allows you to change the FROM address so users replies go to someone instead of a black hole)

MAILC="/usr/bin/tr -d '\\015' | /usr/bin/nail -r 'Xymon <somegroup at company.com>'"   # Command used to send an e-mail with no subject
MAIL="$MAILC -s"                                # Command used to send an e-mail with a subject

We had similar problem about a year ago.  We moved our xymon server from fedora core 3 to SLES 11.  Fedora used mail and SLES 11 mail is linked to mailx.  The windows clients were sending carriage returns in the status ^M (carriage return).  The problem occured on SuSe server but not on redhat server, because mailx expects input text to be in Unix format, with lines separated by newline (^J, \n) characters only. Non-Unix text files that use carriage return (^M, \r) characters in addition will be treated as binary data.  Hence the reason we get notifications that showed up as attachments. Also explains why our  AIX servers didn't have the problem and the windows servers did.  We tried creating a filter by setting  MAILC="tr -d '\015' but had problems.  We didn't spend much time on it.  We switched to mutt.  MAILC="/usr/local/bin/mutt".  Problem went away.

I only noticed this .dat attachement in the smtp test alert by the way.

Hi,

I think this is the issue(from the man page of mailx on centos 6.3:

“Mailx  expects input text to be in Unix format, with lines sepa-
       rated by newline (^J, \n) characters only.  Non-Unix text  files
       that use carriage return (^M, \r) characters in addition will be
       treated as binary data; to send such files as text, strip  these
       characters e. g. by

              tr -d ’\015’ <input | mailx . . .

       or fix the tools that generate them.”

There is a \r carriage return in the alert message. I noticed it before but got no reply on the list.
In previous mailx versions mailx did not convert it to binary data.

Recently noved our Xymon server from a vm running CentOS 5.8 to physical server running CentOS 6.3. Most things work correctly but I'm seeing some of the email alerts having .dat attachments. Anyone know why, and how to fix this?
