[OpenFOAM.com] su root Authentication Error

Sgs · June 27, 2018, 16:48

I ran
$./startMacOpenFOAM
$su root

then typed the password inside the startMacOpenFOAM file
ofuser2017
and received

su: Authentication failure

does anyone know what might cause this?

Sorry not very clear what are you doing. You are entering the password to a file? What are you trying to do what is not working?

I'm trying to install some things within the Docker environment for MAC according to the instructions here
https://www.openfoam.com/download/in...binary-mac.php

Specifically, this line in the instructions:
The image itself was created from CentOS 7.3. If you wish to install any additional tool in your docker container, start it as usual via the startOpenFOAM script, login as root with the password ofuser2017 and use e.g. yum.

But I seem to be misunderstanding something about how to login as root.

I thought I should run the startup script
$ ./startMacOpenFOAM

then try becoming root with
$ su

but the password ofuser2017 seems to result in an Authentication Error.

Any advice would be greatly appreciated.

This seems to work for me on a mac using v1712

Code:

docker run -u 0 -it <docker container> bash

where the <docker container> is found using

Code:

docker images
