NoMachine 3.5 Client Can't Connect to 4.0 Server?

Question

I read that 3.5 client should be able to connect to 4.0 server.

However, when I tried to connect, I got this log: NX> 203 NXSSH running with pid: 4468 NX> 285 Enabling check on switch command NX> 285 Enabling skip of SSH config files NX> 285 Setting the preferred NX options NX> 200 Connected to address: xyz on port: 42228 NX> 202 Authenticating user: nx NX> 208 Using auth method: publickey NX> 204 Authentication failed.

Then, I looked at: https://www.nomachine.com/DT12I00037#3.1

It seems like 4.0 needs some setup for the authentication part. With 3.5, installing the rpm is the only step.

Any idea?

Answer 1

The client 3.5.0 connects to a server by SSH protocol and NoMachine login (public key authentication), while NoMachine 4 (free) supports only connections by NX protocol.

To be able to connect with NX client 3.5.0, you need to install any of the NoMachine Terminal Server or Enterprise products v. 4 that supports SSH connections.

Alternatively, install NoMachine client (version 4) on the computer you are connecting from and use the NX protocol to connect.
