Nagios: 2.10 Plugins: 1.4.9 OS: SLES 9.3 I am having some trouble figuring out how to make check_by_ssh work properly. I think I have done all of the usual troubleshooting and I have googled the issue to no avail: Command as nagios user on the remote server: /usr/local/nagios/libexec/check_load -w 7,7,7 -c 10,10,10 OK - load average: 0.01, 0.04, 0.03|load1=0.010;7.000;10.000;0; load5=0.040;7.000;10.000;0; load15=0.030;7.000;10.000;0; Command as nagios user via ssh on Nagios server: ssh ulwswas01 "/usr/local/nagios/libexec/check_load -w 7,7,7 -c 10,10,10" <MOTD REMOVED FOR PRIVACY REASONS> OK - load average: 0.05, 0.07, 0.04|load1=0.050;7.000;10.000;0; load5=0.070;7.000;10.000;0; load15=0.040;7.000;10.000;0; check_by_ssh attempt as nagios user on Nagios server: ./check_by_ssh -H ulwswas01 -C "/usr/local/nagios/libexec/check_load -w 7,7,7 -c 10,10,10" Remote command execution failed: <MOTD DISPLAYS IN PART THEN CONNECTION ENDS> I get nothing in the log files concerning this and it makes little sense. I have tried everything I need to have working, to the best of my knowledge, as the nagios use and it works. Thanks in advance for any help! Best Regards, Mark L.
