SSH to the core disabled

Hello Guys

This is a late reaction since i was playing with an old version of ctrlX, but it seems that SSH access is already disabled on ctrlX core. Phisical and Virtual. And this seems a part of a plan to increase security, according to this tread:

https://developer.community.boschrexroth.com/t5/ctrlX-CORE/SSH-Intro-CtrlX-Core/m-p/17690

My question is how to have ssh access with superuser rights now that this disabled by default.

Also, my two cents on this subject, is that closing access to ssh and superuser will create an artificial barrier from our solution and the Linux community. 😥

Re: SSH to the core disabled

The SSH connection was closed because of security reasons. To activate it again you need a system user. Please get in contact with your known sales contact person to request it. Or have a look to the contact area on our homepage.

Afterwards you will get a user assertion that can be imported to the ctrlX CORE and adds the system/root user. This for development purposes only! Your ctrlX CORE will be marked as unsafe device further on an must not be used in production mode.

Please always add following information to your request:

  • Your full name and company
  • What you need root access for
  • Serial number of your ctrlX CORE
  • Wanted username and password
  • Usage period (max one year)

Note:
  • A new user will be created with this assertion. There must not be already a user with the same name on the system.
  • Username must start with lower case letter [a-z] or with '_'
  • Username may contain lower case letters [a-z], digits [0-9], '_' or '-'. It may end with '$'
 

For the virtual control there is a bug that the system user is gone in the version 1.8.x. You can use the assertion file attached. This will be fixed from version 1.10 in RM 21.07 on.

From version 1.18 on the system will bring a warning because your system could be comprised by the root user:
