hi all,

 

We are having issues connecting NetApp Harvest to a cluster on one of our remote sites.  This site has a relatively new pair of FAS2650 filers.... we have already implemented Harvest successfully elsewhere.

 

We already ran these commands as taken from NetApp Harvest documtation, on the target filer.....

security login role create -role netapp-harvest-role -access readonly -cmddirname "version"

security login role create -role netapp-harvest-role -access readonly -cmddirname "cluster identity show"

security login role create -role netapp-harvest-role -access readonly -cmddirname "cluster show"

security login role create -role netapp-harvest-role -access readonly -cmddirname "system node show"

security login role create -role netapp-harvest-role -access readonly -cmddirname "statistics"

security login role create -role netapp-harvest-role -access readonly -cmddirname "lun show"

security login role create -role netapp-harvest-role -access readonly -cmddirname "network interface show"

security login role create -role netapp-harvest-role -access readonly -cmddirname "qos workload show"

security certificate install -type client-ca -vserver vserver_name

 

-----BEGIN CERTIFICATE-----

certificate was pasted here....

-----END CERTIFICATE-----

 

security ssl modify -client-enabled true -vserver vserver_name

security login create -user-or-group-name netapp-harvest -application ontapi -role netapp-harvest-role -authmethod cert

 

We then recieved these messages/errors:

[2018-11-27 17:23:39] [NORMAL ] WORKER STARTED [Version: 1.4] [Conf: netapp-harvest.conf] [Poller: filer_name]

Curl output:

[root@ ~]# curl  -H "Accept: application/json" "https://IP_address"--insecure -v

* About to connect() to IP_address port 443 (#0)

*   Trying IP_address...

* Connected to IP_address (IP_address) port 443 (#0)

* The server certificate included a public key that was too weak.

* Closing connection 0

curl: (35) The server certificate included a public key that was too weak.

 

Any advice/suggestions would be very much appreciated!  thanks....

Hi Axsys,

 

I am not familiar with authentication algorithms, from what I found on the web it seems like your client and server are trying to exchange public keys of different lengths (512 bit vs 1024 bit).

 

Did you try to use login/password as authentication instead of certificate?

Public
