Regarding error at host creation

Hi All,
i installed opennebula 4.12 on ubuntu 14.04 using (apt-get)

Log shows the error as
"command execution fail, if [ -x var/tmp/one/im/run_probes] …
, hostkey verification failed"

I tried
(i) onehost sync, and onehost delete and add also…

(ii) added ~ssh/config also

(iii) Permission to /var/tmp/one/im/run_probes also .

However I can run the script “ /var/tmp/one/im/run_probes….”, ( shows all information )

kindly help for a solution.

did you check that you can ssh password-less between all hosts?
Test with manual ssh command between all nodes (master to nodes), and eventually accept host key for first connection.

Dear olivier_sallou,

How we can manually check the ssh password-less between all the hosts?
How we can check ssh password-less is working or not?
