They are in the overlay, but I am not able to login:
[root@barcoo-m ~]# ssh barcoo061-mic0
root@barcoo061-mic0's password:
[root@barcoo-m ~]# find /install/mpss3-2.1.6720-15/ -name authorized_keys
/install/mpss3-2.1.6720-15/opt/intel/mic/filesystem/overlay/system/root/.ssh/authorized_keys
The authorized_keys are identical to the MN (and they work to localhost):
[root@barcoo-m ~]# md5sum ~/.ssh/authorized_keys
/install/mpss3-2.1.6720-15/opt/intel/mic/filesystem/overlay/system/root/.ssh/authorized_keys
10b75abebb122b6bbe557f0353c1b261 /root/.ssh/authorized_keys
10b75abebb122b6bbe557f0353c1b261
/install/mpss3-2.1.6720-15/opt/intel/mic/filesystem/overlay/system/root/.ssh/authorized_keys
and they seem to be correctly processed on the node:
[root@barcoo061 ~]# find /opt/intel/ -name authorized_keys | xargs md5sum
10b75abebb122b6bbe557f0353c1b261
/opt/intel/mic/mnt/opt/intel/mic/filesystem/overlay/system/root/.ssh/authorized_keys
10b75abebb122b6bbe557f0353c1b261
/opt/intel/mic/filesystem/mic1/root/.ssh/authorized_keys
10b75abebb122b6bbe557f0353c1b261
/opt/intel/mic/filesystem/mic0/root/.ssh/authorized_keys
I've noticed that our authorized_keys file had a leading blank line for
some reason, so perhaps that was confusing the SSH implementation
on the MIC? I've removed that and will rebuild the image and try again.
cheers,
Chris
