Hello, we suspect that problem is related to authorization on the remote node with the public key
Can you please check if the issue persists also when you generate a new pair of keys?
Rename the original keys to preserve them:
/usr/NX/etc/keys/node.localhost.id_dsa
/usr/NX/etc/keys/node.localhost.id_dsa.pub
and generate a new key-pair by running on the server host:
# export LD_LIBRARY_PATH=/usr/NX/lib
# /usr/NX/bin/nxkeygen -k /usr/NX/etc/keys/node.localhost.id_dsa -p /usr/NX/etc/keys/node.localhost.id_dsa.pub -t dsa
Ensure that the new keys have proper permissions and ownership
and update the node:
# /usr/NX/bin/nxserver –nodeupdate <node>
