I can ssh login without password, but still get some errors.  
My machinefile format is “host”, one host for each line.  
I started julia using  
`julia --machinefile machinefile`  
but get some tset errors. Any ideas?

Can you try using ClusterManagers.jl instead and see if that works?

ClusterManagers have some special ClusterManager which I don’t have. What I have is passwd less ssh login. The SSHManager was provided in Distributed.

I just tried using Distributed and use:

```julia
machines = [("machine01", :auto), ("machine02", :auto)] 
addprocs(machines; topology=:master_slave)

```

still get the same tset error.
