Writing to /sys as a normal user without authentication

Okay - I know the title of this post is not quite descriptive enough etc. I just don't know what to call it...
I'm trying to get my backlight working fully on my Sony Vaio PCG-GRT390ZP. I can modprobe the sony_laptop module and then echo the different values to the respective files like this:
# echo 5 > /sys/class/backlight/sony/brightness
I'm trying to get some python scripts written to handle the above command. (I'm using python because I'm more comfortable in that than in plain bash / sh, and I have the python packages already.) Because of the scripting, I need to have write access in /sys as a normal user. I'm looking for the safest way to achieve this, as I can't imagine that
chown -R <user> users /sys
is safe at all. Any suggestions? Thanks a lot.

Setting the suid flag for the scripts didn't seem to work, I think because the suid flag only affects binaries (though I could certainly be wrong - that's just what I read)
So I went ahead and added the lines I needed to my sudoers to launch this script as root without a password every time it's run (Since all this does is change the screen brightness I think I should be pretty safe. Unless others have differing opinions?)
Thanks again for the brain jog. Sometimes that's all you need. (Now I just need to set up xbindkeys to launch these scripts I just wrote)

Creation of a normal user without admin rights

Hi,
I am new to oracle apex. Can you please let me know how to create a normal user without admin rights in oracle apex application.
Thanks & Regards,

Welcome to the forum: please read the FAQ and forum sticky threads (if you haven't done so already), and ensure you have updated with your profile with a real handle instead of "866673".
You'll get a faster, more effective response to your questions by including as much relevant information as possible upfront. This should usually include:
<li>Full APEX version
<li>Full DB version and edition
<li>Web server architecture (EPG, OHS or APEX listener)
<li>Browser(s)/version(s) used
<li>Theme
<li>Templates
<li>Region type
(although for your question only the APEX version is necessary).
Assuming you mean a user who can authenticate to an application that uses Application Express Account Credentials?
In APEX 4.0:
1. Go to Home > Application Builder > [Your Application ] > Administration > Create Users and Groups > Create User
2. Enter the User Identification information.
3. In the Account Privileges, specify:
User is a workspace administrator: No
User is a developer: No
4. Complete the rest of the form as necessary.

Pm-suspend: as normal user without changing sudoers and wake-up issue

I'd like to be able to suspend my laptop as a normal user, but I don't want to "break" sudo just to do this. One wiki article (Suspend to RAM) says this:
In fact, only the pm-utils approach can be called without special privileges, see pm-utils#Suspend.2FHibernate as regular user
Linked article from the quote above describes how to make sudo run without asking for password. I wouldn't call that "without special privileges". After all, I can make anything run without special privileges if I edit sudoers in such way.
Is there any proper way to make pm-suspend run as a normal user?
One other thing about pm-suspend... I use netcfg and laptop-mode-tools. After wake-up from pm-suspend my wlan interface is down and hdparm -B value is set to 128. The wiki says that pm-utils is recommend for suspending to RAM because it can handle such things (i.e. restore as much as possible). Is there anything I must configure for this to work? If not, how can I set a custom script to be run after wake-up from pm-suspend?

For example: https://bbs.archlinux.org/viewtopic.php?id=127962
Edit: did you adjust the hdparm settings in laptop-mode.conf?

How to view the No. of connections used in DB as Normal user?

Hi,
I have an clarification about to view the number of connections in DB as normal user.
As sys user, we can see the Max. no. of connections / number of connections used in Database. In the sameway, Do we have any option to
view those details as normal user [I.e. As normal user without DBA Rights ]. Please let me know if its possible.
Kindly clarify me on this.
Thanks,
Orahar.

[Solved] nm-applet does not display in normal user's panel

I installed Arch Linux yesterday. Today, I am trying to get some of the refinements working. I installed OpenBox as a standalone window manager. I got several things working exactly the way I wanted as root, such as networkmanager, nm-applet, and pypanel. When I startx as root, the nm-applet is properly displayed in the pypanel.
Then I discovered that I could not run an X application as the normal user without first running "xhost +" as root. At this point, it dawned on me that I am not supposed to run startx as root, but as the normal user. Duh!
So, I thought I set up everything the same way for the normal user. When I startx as the normal user, OpenBox runs, nm-applet runs, and pypanel runs, but pypanel does not display the nm-applet icon. I can now run my X application as the normal user, so that is good.
My .config/openbox/autostart file is exactly the same for root and my normal user:
(sleep 3 && pypanel) &
(sleep 3 && /usr/bin/nm-applet --sm-disable) &
nm-applet was started by this code, because ps -ef shows it running and owned by the normal user:
[tim@(none) ~]$ ps -ef|grep nm-applet
tim 2311 2306 0 15:27 tty1 00:00:00 /usr/bin/nm-applet --sm-disable
tim 2332 2327 0 15:27 pts/0 00:00:00 grep nm-applet
[tim@(none) ~]$ ps -ef|grep networkmanager
root 497 476 0 14:14 ? 00:00:00 /sbin/dhcpcd -B -K -L -G -c /usr/lib/networkmanager/nm-dhcp-client.action eth0
root 869 476 0 14:30 ? 00:00:00 /sbin/dhcpcd -B -K -L -G -c /usr/lib/networkmanager/nm-dhcp-client.action ra0
tim 2345 2327 0 15:27 pts/0 00:00:00 grep networkmanager
Why does pypanel display the nm-applet icon for root but not for the normal user?

I have now switched to tint2 from pypanel, anyway. It is much cleaner and easier to use. At least in my opinion.

[SOLVED] Can't hibernate with xfce as normal user

Until recently, I can't hibernate using xfce menu as normal user. All other operations such as poweroff, reboot, logout... works.
When I tried systemctl:
> systemctl hibernate
Failed to issue method call: Operation not supported
Failed to issue method call: Access denied
"sudo systemctl hibernate" works
All other operations also works for normal user (without sudo).
When I checked CanHibernate:
>sudo dbus-send --system --print-reply --dest=org.freedesktop.login1 /org/freedesktop/login1 org.freedesktop.login1.Manager.CanHibernate
method return sender=:1.0 -> dest=:1.56 reply_serial=2
string "na"
Which is totally not true since I could hibernate as root.
CanReboot, CanShutdown... returns "true".
As expected, this doesn't work:
> dbus-send --system --print-reply --dest=org.freedesktop.login1 /org/freedesktop/login1 org.freedesktop.login1.Manager.Hibernate boolean:true
Error org.freedesktop.DBus.Error.Failed: Operation not supported
And of course, all other operations work, which is confusing.
Package versions:
> pacman -Q xfwm4 xfdesktop xfce4-session xfce4-power-manager systemd slim polkit
xfwm4 4.10.1-1
xfdesktop 4.10.2-1
xfce4-session 4.10.1-3
xfce4-power-manager 1.2.0-5
systemd 208-1
slim 1.3.6-1
polkit 0.112-1
Any ideas what's wrong? Thanks in advance.

Automatic Adobe Update for users without admin privileges

Hi there,
I have a PC with Windows 7 Professional (32bits) and Adobe Reader (9.4.6)
I have selected "Automatically install updates" in Preferences --> Updater:
The problem is: when a normal user (without admin privileges) is using the system, it turns up an Adobe Box which asks the user to install the Update:
But when the user tries to update, it asks to insert the admin password.
How can I solve this? I would like Adobe Reader updates to be downloaded and automatically installed for users in my PC without admin privileges. Is this possible?
Thanks in advance.
Best regards,
Pablo

Anyone have any further insight into this? Is there a way to simply give the user admin creds but only for Adobe Reader that would permit users to do thier own updates?
I don't want to have to constantly update the MSI I am deploying with GP/LUP if possible.
I am, however simply looking to update 11.0.0 to 11.0.1 ,11.0.2....etc without having to touch GP/LUP/each end user machine

How do you allow all normal users to use the IOSsimulator in Xcode without placing them in the _developer group?

Ever since we've updated Xcode at my place of work normal users have been unable to run their applications in Xcodes iOS simulator because they're prompted with a "Developer Tools Access needs to take control of another process for debugging to continue. Type the name and password of a user in "Developer Tools" group to allow this". I work in an ever expanding office with over 200 employees so adding them all to the _developer group will just be far to time consuming. Is there a way to give normal users permissions to run the IOS simulator?
Here is the message I would like for normal users to bypass.

....I don't see a way around it - either they're in a permissioned group with an applicable login or they're not, right?

Can you please explain what you are trying to accomplish?
To my understanding there is no such thing like a sudo password for a normal user. Sudo allows users to become root based on a sudo list (suoders). The user is then prompted for their own account password to run as super-user or root.

Fingerprint utility is not working for normal users - Tecra M11

Hi All,
I installed windows 7 pro in Tecra M11 laptop and the Toshiba finger print utility is not working for normal users.
It is working only for domain administrators. The TFPU is not working for, normal domain users, local users, local administrators. If we run the utility it will ask to enter the windows password and once we applied the password then the message saying "entered password is not valid" will prompt even if we are trying to use the utility first time.
If we try with a domain admin account it will work without any problem. Can somebody help me to trouble shoot this issue?
Thanks.

People nowadays experienced that no matter How many times we glide our finger it have no response.In this instance, you might be very afraid of Windows password lost by reason that there is a plenty of important data on your PC.
Then what should you do? One choose is fix the Fingerprint scanners, but this method will cost a lot of money. The other is use the Windows password function to solve the problem. Certainly, this is a very safer, faster and easier to use method for you.
According my personal experience, you can try these three ways to re-access to your PC:
Method 1: Login with the default administrator account
* Step 1: Start Windows PC
* Step 2: When you can see the Windows login screen, press ctrl+alt+del keys Twice and it'll show Classic Login box
* Step 3: Type Administrator as Username and leave the password field blank
* Step 4: Press the Enter Key and then you can be able to login the default windows administrator account which is it created by default when install windows.
*Note:* This trick is only work for Windows XP. And when you input the key combination Please don't put the cursor on any account. And if you change the name or password before, you cannot login by this way.
Method 2: Use the previous password reset disk
This method describes how to create and use a password reset disk for a computer that is a member of a domain. You can use a Windows password reset disk to gain access to your Microsoft Windows Professional-based computer if you forget your Windows password. Please click here to learn more.
Method 3: Using Windows Password Unlocker
Using Windows password remove software is could be the fastest and easiest way for you to reset your Windows password while you didn't create a password reset disk before.
There are 2 options for you: recover Windows password with a bootable CD/DVD or recover Windows password with a USB flash drive.
Before starting, a bootable CD/DVD or USB flash drive and a computer with CD drive are required. (Internal CD drive and external CD drive are both OK.
Option 1: Recover Windows password by burning a bootable CD/DVD
Option 2: Recover Windows password by burning a USB flash drive
The whole Windows password recovery process can be divided to 3 big steps:
* >> Step 1: Burn a USB flash drive to remove lost Windows password
* >> Step 2: Set your target computer to boot from USB
* >> Step 3: Recover forgotten Windows password with the burned USB flash drive
In fact, all you need is a *Windows Password Unlocker www.passwordunlocker.com/windows-password-recovery.html which can help you directly reset your windows xp password, and then you can login your XP without a password required. Of course, there are also some other ways to do it, but this way may be most convenient one.

[SOLVED] DBUS boot problems - Mounting system devices as a normal user

I have the [testing] and [community-testing] repositories enabled. A few days ago, probably due to an update, I started having trouble mounting devices and the shutdown/reboot options don't show up anymore on the LXDE exit menu.
I use gvfs for mounting devices as a normal user with PCManFM or Thunar. The error message is "Authentication is required".
After some testing, I found out that by restarting dbus, I could start mounting devices again:
/etc/rc.d/dbus restart
So my guess is that there's some problem with dbus startup. I have it in DAEMONS of rc.conf, as well as .xinitrc, the daemon seems to start correctly on boot, and it worked previously, so I have no idea of what could be wrong.
My ~/.xinitrc:
if [ -d /etc/X11/xinit/xinitrc.d ]; then
for f in /etc/X11/xinit/xinitrc.d/*; do
[ -x "$f" ] && . "$f"
done
unset f

I solved it.
The Wiki page for Mounting for normal users with PCManFM tells to create a "/etc/polkit-1/localauthority/50-local.d/55-myconf.pkla" file specifying the privileges to grant to the user. The problem is that it does not include the privilege needed to mount internal drives (which was what I was trying to mount). To fix it, I added:
;org.freedesktop.udisks.filesystem-mount-system-internal
To the "Action=..." line.
(Though I have no idea why it worked before it broke, or why restarting dbus after initializing my WM fixed it.)
As for the power issues, I've concluded that it was working, but restarting dbus after initializing my WM broke it (my bad for not checking it before restaring dbus). So it all works now.

Allow normal user to start/stop Tomcat

Hi,
Recently I deployed a web app at client's pc running on WinXP SP2. However, I'm not allowed admin rights to that local machine. Is there a way to allow normal user ( like my case) to start/stop Apache Tomcat services without requesting my client to log in as admin to perform this simple task?
Thanks.

compiled it, then "chown root:root test", "chmod u+s test" and it worked.
But is this safe? I have absolutely no knowledge about potential security issues...
I also have thought about periodically restarting calibre, but on the Raspberry Pi, with it's slow ARM, the start takes ages and the processor is completely busy with that task for some minutes.
And that's the reason why I also want to avoid starting an entire second systemd session... Or is this not that resource intensive?

/dev/discs/disc0/part1 /boot ext3 defaults 0 1
I also added a new group called "mount" and added both root and my normal user to it.
I then did
chgrp mount /bin/*mount to change mount and umount to the mount group
then i did a
chmod 774 /bin/*mount
I also made sure that the 3 mount directorys in fstab existed and gave them 777 permissions...
Did a complete reboot... and the normal user still can't use mount... I get this error...
mount: must be superuser to use mount
I'm at my wits end. I believe fstab is correct. I believe my permissions are set correctly... Is there anything else I need to do?
Thanks in advance for any replies...

Usb drive mount by a normal user

how can i make a normal user mount usb drives? i added a line in fstab that allows users to mount /dev/sdb1, but this solves only partially the problem

After a recent sys upgrade, I am having a somewhat similar problem. I can still mount my usb stick, but the permissions are now a little screwy (EDIT: i.e. permission denied when trying to change into /mnt/usb directory).
fstab entry:
/dev/sdc1 /mnt/usb vfat rw,user,noauto 0 0
after performing a mount /mnt/usb the permissions on /mnt are:
d-wxrw-rwx 6 root users 16384 1969-12-31 19:00 usb
well, the permissions on this drive seem strange to me, as well as the 1969 date. Additionally if I look at the directory as root everything is executable, which should not be the case. I've added my username to users and storage in /etc/groups to no effect. I can mount fine using pmount, but I would much prefer things my way, plus i dislike the idea of being forced to mount things under /media (notions of liberty and such)
Any thoughts or additional info needed? I've become stumped enough by this odd behavior to actually register and post.

SQL*Net over IPC fails for normal users

When normal users try to use SQL*Net to log on to a local
database on a Linux box, they get the message "ORA-12546:
TNS:permission denied". An example of this would be the command:
sqlplus scott/tiger@MG8
The oracle unix account can execute the above without problems
and when a normal user sets ORACLE_SID and omits the SQL*Net
connect string it works fine.
Oddly, this is only a problem for connections using the IPC
protocol. If I omit the IPC section from my listener.ora
(leaving only the TCP section), non-privileged users can log on
to local databases through SQL*Net without problems.
I suppose it's not a big deal (there's not that much overhead
going through the TCP loopback port on Linux), but I'm wondering
what's wrong. SQL*Net over IPC certainly works on Solaris.
This is on a S.u.S.E 5.3 distribution of Linux.

Check that your oracle executable is SUID oracle and SGID dba?
I'd have thought that would cause problems with bequeath
connections, so perhaps not.
Wierd error. You might try running an strace on the sqlplus to
see what system call fails.
