Accessing Multiple Systems

If a user has an account with the same login on more than one system (for example, if the user’s home directory is NFS-mounted from a file server), the user ID number should be the same on all of these systems.

For example, suppose user tom has a user ID of 200 on system dept27 and shares files to wsj6700 where he has a user ID of 330. If the files created on dept27 have permissions of -rw-------, then they will not be accessible to him from wsj6700. HP-UX determines file ownership by the user ID, not by the user name.

As system administrator, you need to ensure that each new user login name has a corresponding user ID that is unique within the workgroup, site, or network that the user needs to reach.

For information on whether you should share users’ home and mail directories, see the HP-UX System Administrator’s Guide: Overview.

To allow a user to access a remote system with rcp, remsh, or rlogin without supplying a password, set up $HOME/.rhostsfile on the remote system. See “$HOME/.rhosts File”.

Consider using the Network Information Service (NIS) to manage your users on multiple systems. See the NIS Administrator’s Guide.
