<P DIR=LTR><SPAN LANG="en-us"><FONT FACE="Calibri">I’ve bumped into this a few times in the past.</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT FACE="Calibri">When doing a check_nrpe to a remote server, I get additional “garbage” output that interferes with the nagios check.</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT FACE="Calibri">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.</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT FACE="Calibri">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:</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT FACE="Calibri">On client:</FONT></SPAN></P>
