ssh authorization: nok

perhillerstrom · March 4

Hi, so I am getting below error message when I am trying to run the connection test from STOR2RRD GUI to the IBM FS5200 unit running code 8.5.0.11.

+++++++++++++++

script /home/stor2rrd/stor2rrd/bin/ssh_test_svc.pl timed out after : 30 seconds

+++++++++++++++

I have created a specific STOR2RRD user for the application with MONITOR rights and I have two other 5200 units and two 5000 units running with same settings without any issue. I have tested to remove the faulty 5200 unit and run the ./load.sh script between every trying.

Found the forum thread https://forum.xorux.com/discussion/979/ssh-authorization-nok-testing-vplex and I have tested ./bin/config_check.sh script and I got below response.

+++++++++++++++

+++++++++++++++

Any ideas what I am missing?

Hi,

is ssh working?

ssh -l stor2rrd <storage name/IP>

do you use ssh key based auth or password one, which one do you use it on storage devices which work?

stor2rrd version

I can successfully connect using SSH.

ok, can you answer rest of my questions?

do you use ssh key based auth or password one, which one do you use it on storage devices which work?

stor2rrd version

Sorry, my bad ... I thought information could be seen in the screenshot.

I am using password authentication, and I am using the same type for the rest of the storage units as well. All of the storage units have password authentication with complex password.

But now I noticed the line "Warning: the ECDSA host key for 'NAME' differs from the key for the IP address 'IP ADDRESS'" and maybe that could be the problem?

This specific unit have been a member for a cluster at some part of the installation and I think I did attach the unit to STOR2RRD at some point as well before the cluster was erased again.

Solved it by running ssh-keygen -R [NAME] and the ssh-keygen -R [IP ADDRESS]

Now I got a successful connection from STOR2RRD GUI test connection tool.

I am not sure how it is related, but lets fix it at first.

Check https://superuser.com/questions/421004/how-to-fix-warning-about-ecdsa-host-key

and either remove it

ssh-keygen -R my.server.domain

or change it

ssh-keyscan -t ecdsa my.server.domain >> ~/.ssh/known_hosts

then try connection again, screenshot again

you can even contact us at support at stor2rrd dot com directly to avoid putting here sensitive data
