This NX key is/was never used the way you seem to think it is/was used.

If you want to improve security, using individual SSH keys makes more sense. If you're dealing with minimum password requirements - which you can't enforce on a keyfile, as far as I know - then maybe you should think about using a VPN connection along with regular password authentication. VPNs can use shared or individual keys, though again I'd strongly recommend using individual ones. -Stefan _______________________________________________ x2go-user mailing list x2go-user@lists.x2go.org http://lists.x2go.org/listinfo/x2go-user
