Any, I say, ANY suggestion will be precious!!!!

Re: vg commands as non-root user

Only one way, use sudo, super or other third party software and give access to user to run specific command with uid 0 i.e root.

For example
You can assign user sachin a permission to run a command vgchange with root access. sachin can run only that command with root access.

But overall not a good idea to give a user permission to run that kind of command. Why are we have system admin people?

Re: vg commands as non-root user

Unforunately, you can not run any of these programs without root privledges. You can however, use something like sudo (available at the HP porting site: http://hpux.cs.utah.edu/hppd/hpux/Sysadmin/sudo-1.6.2b1 )to allow users to run these commands as root.

Re: vg commands as non-root user

Hi,

I guess you can't do this without root privilege.
you can get some utilities like 'sudo' to run
some of these command but not a good idea.

Good Luck..

Re: vg commands as non-root user

Hi Riccardo:

You can very easily do this with sudo or by creating a small C setuid program which in turns does system calls. HOWEVER, all of these utilities are only allowed to be run by root for a reason; I don't think that you want ordinary users to be able to destroy your systems.

For your question, it appears that this is a backup issue - the better answer is to write a small setuid program that execute these steps as part of a backup pre-exec script.

Re: vg commands as non-root user

Hi Ricaardo

Since these commands use files which are owned by root , u cannot run these command using a non root id. So you can either use sudo , or su to root , or create a user with root previlages and run the commands.

The easy way to achieve this will be to make use of utility "sudo".
If you describe your situation, may be some one will have more ways to do it.

Thanks.

Re: vg commands as non-root user

I wouldn't suggest doing anything like that. They are for root user for a reason. Pretending to be root user, without accepting the responsibility of being the admin is dangerous. It'd be like suggesting President Bush to take a personal vacation tomorrow in Kabul.

Re: vg commands as non-root user

Hello,

you could put those commands into a shell-script and make that executable through SAM for that user...
Start "sam -r" and add that script (running as "root") to SAM's menu. Then give that user the permission for ONLY that menu.

HTH,
