All commands need administrative privileges

  • 772

I've installed Hping3 on my Ubuntu 8.04, but after installation when I want to use Hping3 I got this error:

Command 'hping3' is available in '/usr/sbin/hping3'
The command could not be located because '/usr/sbin' is not included in 
the PATH environment variable. 
This is most likely caused by the lack of administrative privileges
associated with your user account.

also when I try to run ifconfig I get this:

Command 'ifconfig' is available in '/sbin/ifconfig'
The command could not be located because '/sbin' is not included in 
the PATH environment variable.
This is most likely caused by the lack of administrative privileges
associated with your user account.

First I need to run sudo su and then run the command. Is this normal? Or am I missing something?

when I run echo $PATH I get: 

 /usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/games:/home/amirreza/simulator/ns-allinone-2.33/bin:/home/amirreza/simulator/ns-allinone-2.33/tcl8.4.18/unix:/home/amirreza/simulator/ns-allinone-2.33/tk8.4.18/unix:/home/amirreza/simulator/ns-allinone-2.33/ns-2.33/:/home/amirreza/simulator/ns-allinone-2.33/nam-1.14/
command-line

  1. hping usually needs to be run as root (just like many other network analysis tools).

    That said, both /sbin and /usr/sbin should be in your $PATH. Not being able to run ifconfig is definitely not normal and a major annoyance. Here's my $PATH for your reference:

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

    You can display it using echo $PATH and edit it using export, like this:

    export PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"

    PS. My root $PATH is

    /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/X11R6/bin

    ... just in case.
