[Wamaitha]

Hello, i keyin ioscan and i am getting the following error:
"ioscan: libIO error from io_init: /dev/config - permission denied."
i am still a novice at hp-ux administration, what do i need to do to be able to perform daily tasks without loggin in as root.
thanks in advance.

Hi,

Just to make sure, are you running "ioscan" as root ? If you cant run as root, try # ioscan -kfn.

Also, reading these threads should help.

You can use "ioscan -k" which will show you what is present in the kernel. That's what I usually run anyway because it's faster. The only time I don't use -k is if I've got newly attached hardware I'm looking for.

Actually ioscan with certain options is NOT limited to just superuser.

try

ioscan -fun

if i logged in ran ioscan with no options i get the error, but with options i am able to perform an ioscan. just to be sure there is nothing i can do as an admin to be able to perform ioscan without loggin in as root?
thanks in advance.

Hi,

You asked "Logged in ran ioscan with no options i get the error, but with options i am able to perform an ioscan. just to be sure there is nothing i can do as an admin to be able to perform ioscan without loggin in as root? "

Yes, a normal user cant do anything with ioscan..

Hi,
That is because ioscan without options updates /dev/config and /etc/ioconfig, which only root has write permission, there is a box where because of mad developpers trying to hack root passwd I only connect myself and had to compile a sudo so I have no passwd without timeout and works only when I call an alias of ksh...
So on this box I put myself in the /etc/group file in the groups bin, root, adm, sys, mail and modified the permission on the groups to /dev/config /dev/kmem /etc/ioconfig, and most files in /etc so in case Im stressed I will not sudo and can still do some tasks...
Dont forget there is also the possibility to grant yourself to all (most) tasks restricted sam (sam -r)

All the best
Victor

As a normal user you can not run just plain ioscan. And as an admin there is nothing you can do about that.

[Paul Sperry]

Victor has something there. You could use sudo or super to grant normal users access to ioscan (by it's self or with options)

[Wamaitha]

thank you all, all the answers you provided made. as a user ran ioscan with options so as not to get an error.
Gracias all.
