I just configured a cluster with Centos 7.5 and latest Warewulf (stateless). The nodes boot, however, I am unable to ssh successfully to any of them. I have set up ssh keys and imported the /etc/passwd, /etc/groups, and /etc/shadow files into the node configuration. Permissions look fine. I've tried everything relevant from the documentation or discussions here, to no avail -- any suggestions on how to debug this would be greatly appreciated! Thank you!

Try not being root... just a normal user.

For root to work you would need to provision his authorized keys.

Thanks, I just tried, and I get a bit farther, but still no success -- ssh keys still did not worked. Password authorization succeeded but the connection was closed anyway. I am wondering whether there is a problem with the /home directory mounting.

What does the file [chroot]/root/.ssh/authorized_keys look like? Does
it include cluster.pub ?

One think you could try doing, as long as the default cron wasn't
removed... Create a authorized_keys file Warewulf that has
cluster.pub in it. Import that file with
"--path=/root/.ssh/authorized_keys" and add it to the node with:

wwsh provision set [node] --fileadd=[name]

Wait around for 5-10 min or so. Then try running:

ssh -i /root/.ssh/cluster 192.168.10.10

If you tail the apache access_log you should see a request from the
node come in that's something like: /WW/file?fileid=[id] ... Where
[id] is the ID of the file. You can get this by running:

wwsh object dump [file name]

Jason, I had done all these things (and checked permissions in the file list), but I did it again, with --path as you suggested, with the same result, ssh keys or password still don't work for root. I don't see any new messages in the apache access log as a result, could that be a problem?

There is no ssh module when I run wwinit, but  ssh_keys works:

# wwinit ssh_keys

ssh_keys:     Checking ssh keys for root                                     OK

ssh_keys:     Checking root's ssh config                                     OK

ssh_keys:     Checking for default RSA1 host key for nodes                   OK

ssh_keys:     Checking for default RSA host key for nodes                    OK

ssh_keys:     Checking for default DSA host key for nodes                    OK

ssh_keys:     Checking for default ECDSA host key for nodes                  OK

Done.

Try running wwinit ssh

That's what I meant.  It should work.  I'm away from my computer so I'm out of ideas.  Sorry.
