Solaris

It is working fine on few of other servers with non root user also. I was trying to compare both configurations like .profile and /etc/profile, but couldn't found much on that.
Can it be anything with colums, if I export it with .profile of non root user ?

Maybe try md5sum /usr/ucb/ps on each server and see if any differences in executable.

Maybe just accept the security behavior and figure out how to deal with it. What's the problem with the output being truncated?

Did it previously work? If so, what might have changed?

To get the extended args past the 80 characters available in /proc/[pid]/psinfo, either pargs or /usr/ucb/ps needs to be able to open and read /proc/[pid]/as - the address space of the process.

If you really need this capability for non-root users, you can set the setuid bit on the permissions for /usr/bin/pargs or /usr/ucb/ps:

Code:

chmod 4555 /usr/ucb/ps

Doing that will give all users the ability to dump the entire process argument list along with the entire process environment - for all processes. You also need to be really careful with changing permissions on Solaris base OS binaries - the standard Solaris install hard links multiple utilities to the same underlying binary, so if you change the permissions of one you change them all (there are misguided - at best - security recommendations out there that do this and wind up breaking things right and left...)

A better (worse? very hackish...) way might be something like this (off the top of my head, totally untested):

Code:

cp -p /usr/ucb/ps /usr/ucb/ps_priv
chgrp sysadmin /usr/ucb/ps_priv
chmod 4550 /usr/ucb/ps_priv

That would only allow users who are members of the sysadmin group to run the command.

They might be running an older release of Solaris with which there wasn't yet this enforcement.
Have a look to /etc/release
As I wrote, it is the expected behavior. Nothing you can change without raising your privileges as I already suggested.

Permissions and ownership is exactly same in a working and non working server for /usr/ucb/ps.
Working server is update-5 and non-working is update-8

Solaris 10 ps(1b) manual page states:

Note: The wide output option can be viewed only by a superuser or the user who owns the process.

So if it works with update 5 and its manual page has the same statement, that is a bug here, not the other way around.

I read it, but still trying to understand what setting is there in other similar servers, where this is working (without sudo)
