General :: Aliases Work After Running Sudo SU Command?

May 7, 2010

I can make aliases fine by editing the .bashrc file in my home directory, but the first thing I do when I open a terminal window is sudo su so I don't have to type sudo in front of every command. The problem is, I am then not able to use my aliases. How can I make aliases that work after I run the sudo su command?

General :: Specify Password For Sudo Command When Running Bg Process?

Jun 23, 2010

I'd like to start a background job using the sudo command and route its output to a file. This presents a problem because the prompt for the password doesn't work properly. It looks something like this when I try it:

Mac:server user$ sudo php crossdomain_server.php > data/crosscomain_output.txt &
[3] 30303
Mac:server user$ Password:
[3]+ Stopped sudo php crossdomain_server.php > data/crosscomain_output.txt
Mac:server user$

Basically I'm not properly prompted for the password and as soon as I type anything in my background job fails because it didn't receive the password. Is there any way to execute a sudo command by supplying the password on the same line as the command?

Ubuntu :: Su Command Won't Work, But Sudo Will?

Oct 16, 2010

I was attempting to install the fglrx driver on my new ubuntu insallation, following a guide I found from google. At one point it says I need to login as super user, so I tried and no matter how many times I try it just keeps saying authentication failed. I even tried typing in my password with 1 finger, multiple times, every single time, authentication failed. So I decided to try the sudo command with fdisk -l, worked flawlessly. Tried the su command again, authentication failed, I have no idea what in heck is causing this but it just won't stop happening.

Slackware :: Getting Aliases To Work As Root?

Aug 22, 2010

How can I get aliases working as root? Here is my Slackware 13.1's /etc/profile file followed by my *Slackware 11's* /etc/profile file [as a comparison]. My Slackware 11's root aliases work in addition to my username ones *without* needing a separate .bashrc in my home dir. In S13.1 I have created a .bashrc for my username and it works fine, but I want those same aliases operating when I'm root, and cannot for the life of me figure how to achieve it.

S13.1 /etc/profile:
# /etc/profile: This file contains system-wide defaults used by
# all Bourne (and related) shells.
# Set the values for some environment variables:
export MINICOM="-c on"
export MANPATH=/usr/local/man:/usr/man
export HOSTNAME="`cat /etc/HOSTNAME`"
export LESSOPEN="| %s"
export LESS="-M"
# If the user doesn't have a .inputrc, use the one in /etc.....

Fedora :: Defined Aliases In File Not Working - No Command Found

Apr 15, 2011

Defining tcsh aliases through a .aliases file has worked perfectly for me for years and years using cygwin and older versions of mandriva. I am encountering very annoying and mysterious problems when attempting to do the same thing with a .aliases file in a fedora 64-bit VM. Strangely, if I define aliases in the file, they won't work, but if I do so on the command line, then they will.

Here's a simple example: Suppose I define an alias for "ls" in the file:
alias ls '/bin/ls'
Then source the file. This happens:
me: ls : Command not found.
me: alias ls
me: /bin/ls
file1 file2 file3 etc.
me: unalias ls
me: ls
file1 file2 file3 etc.
me: alias ls '/bin/ls'
me: ls
file1 file2 file3 etc.

A second example: if I place either of these lines in my .aliases file:
alias d '/bin/ls -alF !:1'
alias d '/bin/ls -alF !*'and source the alias file, this happens:/ me: d
Bad ! arg selector. However, if I define the alias on the command line:
/ me: alias d '/bin/ls -alF !*'then the alias behaves correctly:/ me: dtotal 376

General :: How To Alias A Command For Sudo

Sep 25, 2010

I have an alias that I would like to use both as a regular user and as root, via sudo. Specifically, it is this:

alias rm=trash This works fine as a normal user, and it works fine when I use sudo -i to get a root shell prompt, but if I use sudo rm, the alias does not apply. So where do I need to put my alias so that it works in one-off sudo commands?

General :: Execute A Command After Sudo?

May 4, 2011

I am working in a CentOS environment with numerous CentOS machines. Currently there are multiple developers that each have their own login/home directory and then for various admin tasks we all share a single super user account.

The problem

I have a number of aliases, variables, functions, and settings that exist in my personal login's .bash_profile. None of these are available in the shared super user's .bash_profile. My current work around is that everytime I sudo in as the super user and I re-execute my .bash_profile from my personal user's home directory. I am not allowed to edit the init stuff for the super user

The Question

Is there any way I can automate my sudo sequence such that it will execute my personal .bash_profile after I've executed sudo without requiring me to edit the super user's bash init stuff?

General :: Execute Root Command Without Sudo?

Jan 24, 2010

On my ubuntu I have a command pm-suspend, which puts the computer to sleep. It has to be run with sudo. Since it is inconvenient to be forced to type the password every time I want my computer to sleep, I thought maybe there's a way around it. Naively I thought that if I'd create a script as root, that invokes pm-suspend, and then let anyone execute that script, I could run that script as my own user and then that script would be considered run by root and hence be allowed to run pm-suspend. Obviously that didn't work. The root-check procedure in pm-suspend still found out that the original executor was someone different from root.

Still I think something similar (although slightly more elaborate) should work.I'm thinking about the process that allows the user to mount hard drives for example. Normally root is required, but it is somehow bypassed by the gnome utility mounting.

General :: Sudo Versus SU - SAX2 Command?

Jun 3, 2010

I've been using SuSE for a while and something has been bugging me. Not a show stopper, but nevertheless, an interesting one. Most tutorials, forum posts, etc. recommend using a sudo command to accomplish stuff. For example:

sudo make install
sudo vi file

However, this does not always work. For instance, I was recently working on a resolution problem with my ViewSonic VX922 - it would only display at 1024x768 rather than the native 1280x1024. Viewing some posts, I found the command "sudo sax2 -r". What I discovered is that there seems to be a big difference between sudo and su

drkhelmt@SPACEBALL1:">sudo sax2
root's password:
sudo: sax2: command not found
SPACEBALL1:/home/drkhelmt: #sax2
SaX: Checking update status for intel driver
SaX: initialization already done
SaX: cal [ sax2 -r ] if your system has been changed !
SaX: startup
SaX: X server:0.0-> grant
SaX: importing current configuration
SPACEBALL1:/home/drkhelmt: #

So the question, why does the command sax2 (and others) work when after the su command rather than a sudo?

General :: Usage Of Sudo Command In Ubuntu And Red Hat?

Apr 18, 2010

In Red Hat, suppose if root user wishes to give a privilege to run the fdisk command to a user named sam.And he makes appropriate configuration changes in /etc/sudoers file. Now when sam wishes to run the fdisk command, then he has to issue:

[sam@system43~]$sudo /sbin/fdisk -l
Password: But in ubuntu, after the same configuration being done, what sam needs to do is:
[sam@somesystem43~]$sudo fdisk -l
Password: ***

That means, in ubuntu the user need not type the full path of the command. I wish to know how can I make red hat system work like ubuntu as far as the sudo usage is concerned.

General :: Sudo For A Single Command With No Password Entry

Apr 20, 2010

I wish to allow a user to use sudo to run a single command (service app status) to determine if my application app is running, in my sudoers file i have: user ALL= /sbin/service app status I understand that there is a parameter called timestamp_timeout that will set the timeout for the 'user', but requires at least 1 entry of the root password.

I wish to allow the user to do "sudo service app status" and not have to enter the root password ever(maybe once is ok), but still make the user enter the root password for all other root activities. Is there a way to prevent the password entry for this command only and no others?

General :: Ubuntu / Sudo Also Doesn't Work

Jun 30, 2011

I have ubuntu server 8.x which works Ok but the other day I changed the owner of some files "the directory /etc" from root me. Now a lot commands do not work like reboot and such. So I tried to put ownership back to root and I can't. I say I dont have proper privilege. Sudo also doesn't work. I conect to the server using ssh with putty. What could I do to fix the problem? Update to the new version? This server has been working really well for a few years. The reason I changed the owner of the directory to myself is so I could edit some config files from my windows machine using a FTP client like WinSCP.

General :: Sudo Command Occasionally Asks For Root Password?

In Ubuntu 10.04, I logged in as user1 and when I open a new terminal and issue any command it is asking password.user@ubun-laptop:~$ sudo ifconfig[sudo] password for user: It is asking for password only for first time.From the next command onwards it is not asking.Can some one please tell me if it is possible to issue ONLY ONE COMMAND, in which even if the password request comes, it will automatically fill the password.Just like "ps -elf | grep NetworkManager". I am expecting any combination of commands in a single line, so that password is filled automatically IF PASSWORD IS ASKED. If password is not asked, the command must be executed.

General :: Why Doesn't 'sudo Gedit' Work In Vinagre

Oct 13, 2010

I've set up a low cost box with Ubuntu Lucid Lynx at home behind a router, and managed to get remote access running. My goal is to be able to host a small website and work on it remotely, so I isntalled ftp (vsftpd). When I tried to edit the vsftpd.conf file in Vinagre from work, I could only open it read-only, no surprise. When I tried 'sudo gedit' or 'sudo gedit /etc/vsftpd.conf' from terminal in Vinagre, I received the prompt for the password to elevate privileges (again, expected); however, after I hit Enter, nothing happens. I've tried a bunch of different things, but I can't get it to work. I can stop & start my ftp service with 'sudo service vsftpd stop/start' and it seems to work fine.
