Sudo Is Can Not Find Program / Path Related Issues

So right now in some of my servers, some of my users are in the Wheel group and then I have some users who fall under /etc/sudoers. Don't have any consistency, however I want to change that.

I know that wheel group is legacy.

SUDO gives an audit trail I believe under /var/log/secure.

I'm wondering what others have experienced and setup which worked better in the long run, place users either in wheel group or in SUDO?

Hello,

I am getting the follwoing error for Red Hat Enterprise Linux Server release 6.6

sudo su -
sudo: >>> /etc/sudoers: syntax error near line 118 <<<
sudo: parse error in /etc/sudoers near line 118
sudo: no valid sudoers sources found, quitting
sudo: unable to initialize policy plugin

cd /etc/sudoers.d/
-bash: cd: /etc/sudoers.d/: Permission denied

Could you help me to figure it out. As a root user am able to access but as normal user it is not allowing to sudo su - command.

vi /etc/sudoers.d/access
username ALL=(ALL) NOPASSWD: ALL

Please let me know if any additional formation required.

When I place following line in /etc/sudoers
tom ALL=NOPASSWD:/sbin/service tomcat6 start

and..
# su - tom
# sudo -s
I get following message

Sorry, user tom is not allowed to execute '/bin/bash' as root on example.com

I did not understand can some make me understand why I am getting this message.


Thank you

Hi all,
I have a script where every line needs to be prefixed with sudo.
I was advised to run it as $ sudo /path/to/file.sh

This script needs to be scheduled in crontab to run. If I run it as above, will I be prompted for a password?
Also, one of the lines in the script is;
scp -r root@rem_server:/source/dir /local/dir
Does that mean I will have to provide two passwords: one for sudo and one for root?

Thanks,

Hi,

I installed ghostscript via yum package manager. Later I wanted a newer version of ghostscript and compiled it from source. "make install" placed the gs executable file under /usr/local/bin/gs. This works if I run the command with absolute path, but if try to run gs, the shell will output

"-bash: /usr/bin/gs: No such file or directory"

if I echo the path variable it will display

/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin

If i run whereis it will give me the correct path
gs: /usr/local/bin/gs

How do I make it work so that typing "gs" will run the executable file from the /usr/local/bin/gs?

(I am using Centos 6)

Thanks.

System Info:

I have normal user in CentOS 7 whose name is "mostafa" (the name of the account).

I naturally have another user called root with all privileges. User "mostafa" is put into sudoers file, too.

The OS is installed in VmWare, so the system is all mine.

Problem:

Now I create a file with touch file.sh and put a command in it, but when I want to run it with Code:

sudo ./file.sh

, an error is shown that the command Code:

./file.sh

does not exist. But if I Code:

 sudo chmod 777 ./file.sh

then it gets run. My question is that, why should I use Code:

chmod 777

when I myself have created the file, and I am in sudoers.

Can anyone explain me why shuold I still use Code:

sudo chmod 777

when the creator of the file is me.

I have an external disk but I can only write to it using sudo, not as my normal user.

The commands I've issued a
Code:

sudo mkdir /media/USBSSD
sudo mount -t auto /dev/sda1 /media/USBSSD
sudo chmod 777 /media/USBSSD
sudo mkdir /media/USBSSD/share

How can I set it up so that other users can write to it?

I'm a total total noob who is trying to download Linux Mint on a Mac OS X using a USB drive. I know there is some way to go into terminal and convert the iso file but I don't know how.

Here's the things I have tried so far: 1. sudo dd bs=4M if=[linuxmint-17.1-cinnamon-64bit.iso] of=/dev/disk2s1 (result: dd: bs: illegal numeric value)

~/path/to/Users/[my name]/linuxmint-17.1-cinnamon-64bit.img ~/path/to/Users/[my name]/linuxmint-17.1-cinnamon-64bit.iso -bash: /Users/[my name]/path/to/Users/[my name]/linuxmint-17.1-cinnamon-64bit.img (result: No such file or directory)
Maybe for #1 the "/dev/disk2s1" part is wrong? How do I find the number for the USB that goes after "dev/sd"? (I can only find "dev/disk2s1").

I have also tried to just mount/unmount the USB and drag the iso file into source/destination, to no avail.

Thanks so much!

hi guys,

sick of typing sudo yum install package

so i wrote...or rather am trying to right a simple script to do this
with a simple command:

heres what i have:

#!/bin/bash
echo "Enter package name to install..."
read $P
sudo yum install $P

it doesnt seem to want to take the variable...it just runs
sudo yum install ...$p is ignored...i also tried "$p" but this
doesnt work either...what is the correct syntax to get a command to read a variable...is this possible...aaaaaaah it must be.
