I have a Vaxstation 3100 running Ultrix-32 V3.0 (Rev 64) UWS V2.0. I want to login as operator to shut the system down without becoming root and doing a shutdown. I tried login in as operator and typing the operator passwd. After a minute of turning my screen to gray and giving me a pointer it returns me to the login screen again. I read in the release notes for version 3.1 that you can't do this so I did what they suggested, I logged in as me and then su to operator as operator I typed s for shudown and it said I have to this from the console. I was working directly on the workstation. I have tried this on a couple of other vaxstations and get the same problem. Any ideas would be greatly appreciated.

This simplest answer here is simply not to bother with opser at all. Change the /bin/shutdown program so that it is suid root, and readable/ exectable only by group "operator". Then add your or your "operator" logins to an /etc/group line for operator. After doing this, any of them can invoke shutdown directly, without haveing to "become" root. as: su chgrp operator /bin/shutdown chmod 4750 /bin/shutdown Modify the general notions as appropriate to your own sites notions of security and who has privileges... -- George Robbins - now working for, uucp: {uunet|pyramid|rutgers}!cbmvax!grr but no way officially representing arpa: cbmvax!grr@uunet.uu.net Commodore, Engineering Department fone: 215-431-9255 (only by moonlite)
