Gerald, I am able to successfully authenticate over ssh.

And it seems you cannot execute the check on the server either, as there is no "OK" at the end. Run ssh with -v to see if it is actually able to authenticate successfully and also check the server log at 192.168.1.111 for output from the sshd server or pam service. It should tell you why the connection has been refused if so... -Gerald > > > Regards, > > Vikee Kumar > Ops Team, Vidder India > > > > On 07/02/18, 1:37 PM, "Gerald Vogt" <v...@spamcop.net> wrote: > > > > On 07.02.18 09:00, Vikee Kumar wrote: > > Hi All, > > > > I am getting below error while trying to do run check_by_ssh from > > icinga-master to client. > > > > PFA attached Image of scenario what I want to do. > > > > root@mgmt-vikee:/var/lib/nagios# /usr/lib/nagios/plugins/check_by_ssh -H > > 192.168.1.111 -l nagios -i /var/lib/nagios/.ssh/id_rsa -C > > "/usr/lib/nagios/plugins/check_dummy 0" > > > > Remote command execution failed: > > ############################################################### > > > > root@mgmt-vikee:/var/lib/nagios# /usr/lib/nagios/plugins/check_by_ssh -H > > 192.168.1.111 -l nagios -i /var/lib/nagios/.ssh/id_rsa -C > > "/usr/lib/nagios/plugins/check_dummy 0" -vvv > > > > Command: /usr/bin/ssh > > > > Argument 1: -l > > > > Argument 2: nagios > > > > Argument 3: -i > > > > Argument 4: /var/lib/nagios/.ssh/id_rsa > > > > Argument 5: 192.168.1.111 > > > > Argument 6: /usr/lib/nagios/plugins/check_dummy 0 > > Well, run exactly the command it shows you and you should see the error: > > /usr/bin/ssh -l nagios -i /var/lib/nagios/.ssh/id_rsa \ > 192.168.1.111 "/usr/lib/nagios/plugins/check_dummy 0" > > -Gerald > > > > > Remote command execution failed: > > ############################################################### > > > > Regrads, > > > > Vikee kumar > > > > > > > > _______________________________________________ > > icinga-users mailing list > > icinga-users@lists.icinga.org > > https://lists.icinga.org/mailman/listinfo/icinga-users > > > _______________________________________________ > icinga-users mailing list > icinga-users@lists.icinga.org > https://lists.icinga.org/mailman/listinfo/icinga-users > > > _______________________________________________ > icinga-users mailing list > icinga-users@lists.icinga.org > https://lists.icinga.org/mailman/listinfo/icinga-users > _______________________________________________ icinga-users mailing list icinga-users@lists.icinga.org https://lists.icinga.org/mailman/listinfo/icinga-users _______________________________________________ icinga-users mailing list icinga-users@lists.icinga.org https://lists.icinga.org/mailman/listinfo/icinga-users
