Error received in Netsaint is "Host key verification failed." I run the command ( check_by_ssh -H <remote host> -l netsaint -C < command on remote machine> ) from the shell as the netsaint user and the command executes they way it should. Just for fun, I scheduled a cron job using netsaint's crontab and the job executed the way it should have. It seems as if in my environment the Netsaint core engine cannot execute plugins that use ssh. Some sort of thread issue, when it gets to the second child that uses the ssh command, it will not authenticate. I have also written some plugins that can use either ssh or rsh. When using rsh the plugins work great. When using ssh through the Netsaint engine, same type of authentication problems occur as with check_by_ssh. When I execute the plugins from the shell or cron, they return the results as expected. I have generated pub/priv keys and have created the authorized_keys file on the remote systems as expected. All testing from command line works fine. I am running Netsaint 0.0.7 on Redhat Linux 7.2. Netsaint process's are all owned by the netsaint user who is part of the netsaint group. Netsaint is started with the standard netsaint script -> /etc/init.d/netsaint. Ssh version: 3.4p1 Remote ssh version's: 2.92 & 3.4p1 Can anyone help? Has anyone successfully implemented remote plugins using ssh? Does nagios solve this problem? -john w </BODY> </HTML>
