Re: [xcat-user] host based authentication

2020-01-22 Thread Lachlan Musicman
Can't speak highly enough of FreeIPA and SSSD. Support is knowledgable
and excellent even at the free level (email lists, documentation).
RedHat support means that integration with Active Directory is easy -
if necessary.  Have used it in two large and complex organisations
with success that surprised and impressed me.

Am in the process of migrating to it in my current role. It's the
authentication and authorisation gold standard for organisations of
size or complexity.

thanks for mentioning this. I was struggling to design simple AND secure 
hostkey deployment mechanism. Good to know freeIPA can manage this.


cheers

Re: [xcat-user] host based authentication

I have it working in place.

The process is a little bit cumbersome but it’s woking. I’m using FreeIPA too 
so the hostkeys are stored on LDAP, it's integrated.

The only issue that I’ve is that I needed to disable the remoteshell script 
from xCAT and use another one that we have created and unfortunately all the 
nodes shares the same hostkeys.

I can describe exactly what we have done if you want, but it’s tied to FreeIPA.

Re: [xcat-user] host based authentication

2020-01-21 Thread Kevin Keane
The known_hosts file has nothing to do with host-based authentication. It
is used to verify the identity of the host when using SSH with standard
user-based authentication.

I believe you are thinking of rhosts? Generally speaking, using host-based
authentication is highly discouraged for security reasons, but in an xCAT
scenario it can make sense.

[xcat-user] host based authentication

2020-01-21 Thread Imam Toufique
Hi,

Quick question, before I jump in finding my own solution.

Is there anything in xcat that would allow setting up host based
authentication?  I know root can ssh from the mgmt. node to all the nodes
in the cluster.  I am referring to user authentication , based on
/etc/ssh/known_hosts file, where there is a list of hosts and their
respective keys.

thanks.
