I'm Pab, just like to know, How can I allow a new user to run specific software like sqlplus.
Scenario:
I have an oradb@database user where i can execute sqlplus /nolog command, but when i created a new user named allan@database the bash says....-bash:sqlplus: command not found.
How to find, what are the files (system & user) created after login to the system in RHEL 5.0?
Any single command available?
Is there a system admin tool for RHEL on montioring and logging system memory used and released that can dump to a log file?I'm having an issue with memory not being released when an application is closed. I need to have a tool monitor and log so I can troubleshoot to verify that it's an application not the OS.

What is the difference between creating a "regular" user and creating a "system" user on Linux?
For example:
Code:
adduser john
Code:
adduser --system john
Similarly it seems there are normal groups and system groups. Doing an internet search and reading man pages does not give much information on the whole concept of system and regular user/group.
Any idea, does RHEL5 support NTFS system.??

The Completely Fair Queuing (cfq) scheduler in Red Hat Enterprise Linux 5appears to have worse I/O read performance than in version 4. It appears as though the Completely Fair Queuing I/O scheduler (cfq) has a regression and thus exhibits reduced read-side throughput which can affect performance for both local and NFS mounted file systems.
One way to mitigate this is to set the cfq's slice_idle parameter to zero. To change this value, execute the following command echo 0 > slice_idle in the /sys/block directory appropriate for your situation, as shown below:
echo 0 > /sys/block/hda/queue/iosched/slice_idle
We are using NFS file systems in RHEL 5.3. I would like to know how to find which /dev/Device is being used by the NFS file systems, so that I could try setting the slice_idle to '0' to see if there is any difference in performance? In /etc/fstab I only see the actual NAS volumes for the NFS file systems.
I often get responses from people who first say: "Are you sure? You want your network to be exposed to the outside world?" I am not experimenting on a Production Server of NASA or any Security Concern Department. Friends, there is no harm in experimenting on your personal computer or on a test computer which is isolated from the production environment. Look at hackers! What do they do? If they don't know how security is breached then how would they come up with security measures?
If my question reads... "How to let any user perform Administrative Tasks on a Linux System irrespective of his/her privileges on that particular system?" then I would not get the right answers in the first place. They will say... "You are letting everyone destroy your system... are you sure you want to do that?" My question is: Why should we restrict ourselves from experimenting even if it sounds weird to other people?
I give you an example where it is desirable to let an unprivileged user perform certain tasks. You want to know if there are any employees in your office who are storing videos in their home directory and filling up the disk space to a great amount. You have a department called "Command Center or Data Center Operations or Help Desk" call it whatever you would, whose work is to monitor such activities, and you create an account "monitor" for them to monitor such activities but they are not able to do them:

I would like to trace a user's activity by monitoring system calls. Is there a way to use strace such that at startup it will begin tracing all system calls? Or is there any other method to automatically trace the system calls used during a user's session automatically without having to call strace manually?

Is there a way to determine this in linux?

View 2 Replies View RelatedI am running Debian Lenny with the default Gnome desktop. When I set up a new user the sound is not available. It says the device in not installed. I have used the Gnome system menu as follows.System, Administration, Users and Groups, then used the add user button and entered the appropriate info. I then went and clicked on the properties button and then the User Privileges section and checked off the "use audio devices" button. Still no sound. When I go to System, Preferences, Sound, Devices, and do the sound tests I get report that device is not installed.
When I am logged in to the user (jon) that I set up when doing the D.Lenny install, the sound on all various media play back works fine.There is one with 1 exception when loged in to this user(jon). I can not get any sound from the system sounds like select check box = toggle .wav, chose menu item = beep, etc. It would be realy nice to know how to repair or configure tis issue as well.under system info, pci devices it lists as follows Multimedia audio controller, Intel Corp 82801FB/FBM/FR/FW/FRW. Mother board is a ECS 915P-A2 and I guess about 2007 or so vintage. 1 G mem installed and a P-4 2.66 chip. It has the sound built in to it. It works fine on WinXP.
