Addprocs behavior changed in recent update -- have to enter password now

Specific Domains Julia at Scale

I have passwordless ssh login setup to my server like:
ssh csidrane@myserver
But then when I go into my terminal and I type:
using Distributed
addprocs([(“myserver”, 1)])

it used to work just fine! About a month ago. And now all of a sudden I am getting errors.
I was getting errors that askpass was not installed - so I installed it, but then it started asking me for a password with a prompt with an incorrect username e.g.:
A window pops up (not what I want if I am gonna run this on a server) and it says “Enter password for chelseas@myserver” which is not the username I want to be using.

Any help?

Julia 1.6

If you want to use another user name, shouldn’t you say so in the machine specification string? Something like

using Distributed
addprocs([("csidrane@myserver", 1)])

Thanks! wasn’t sure how to change the username. Now I’ve tried that and get a different error:

julia> addprocs([("csidrane@tula", 1)])
sh: 2: [: x: unexpected operator
sh: 2: [: x: unexpected operator
sh: 1: cd: can't cd to /home/chelsea
sh: 2: /home/chelsea/Software/julia-1.6.1/bin/julia: not found
ERROR: TaskFailedException

    nested task error: Unable to read host:port string from worker. Launch command exited with error?

Now Software/julia-1.6.1 is a directory that exists on my home machine but it doesn’t exist on the server tula. This hasn’t been a problem before.
