NRPE - garbage output

[Sloane, Robert Raymond]

It looks like you might be running the manual check as root rather than
as the same user that NRPE uses.  There might very well be some
difference in the environment between the two runs that is causing your
problem.

Have you tried turning on debug in NRPE on the target system?

Subject: [Nagios-users] NRPE - garbage output


I've bumped into this a few times in the past.
When doing a check_nrpe to a remote server, I get additional "garbage"
output that interferes with the nagios check.
I was running nrpe 2.11 and found a supposed fix in 2.12.  I've since
upgraded both the nagios server and client to nrpe 2.12 and restarted
everything with no change.
If I run the check on the client everything works as expected.  If I run
it via check_nrpe it doesn't.  The following is an example with relevant
security changes:
On client:
# /usr/lib64/nagios/plugins/contrib/check_ftp.pl -H SERVERNAME -u
USERNAME -p PASSWORD-f index.html
OK: Opening ASCII mode data connection for index.html(236 bytes).
Transfer complete.
client nrpe.cfg entry:
command[check_ftp2web]=/usr/lib64/nagios/plugins/contrib/check_ftp.pl -H
SERVERNAME -u USERNAME -p PASSWORD index.html
On server:
# check_nrpe -H SERVERNAME -c check_ftp2web 
WARNING: server says: Transfer complete.
' ABOR': command not understood


Note the garbage and also the different result  OK vs WARNING
Any suggestions is appreciated.
