SSH

Setting Up USS

  1. Make sure you are logged into your mainframe and in USS (OMVS) using a 3270 emulator.

  2. Make sure your ID has UID 0. To verify it, use the id command in USS:

    > id

    You should see something like:

    > uid=0(<USERID>) gid=0(<GROUPID>)
  3. Modify the permissions of the /tmp directory:

    > chmod 1777 /tmp/

    If you receive a file or directory not found message, enter the following commands to first create the directory and then modify the permissions:

    > mkdir /tmp
    > chmod 1777 /tmp/
