User adding scripts?

evilchild · 11-18-2003, 10:28 PM

just wondering, I'm working on a script that add users requesting shell accounts to a system by having the user login as "newuser" which runs the script. But with my novice script programming skills, the only script I"m able to write for this task must run with some root permissions leaveing large sercurity holes in the system, with all that said, has anyone seen any scripts or programs for easiely adding users?

Do you mean 'ssh' logins?

I have a script that easily adds users, but, you must be root, your not going to find a script to add users that doesnt run as root, we'll you might, but its not advised.

The script is at http://www.ccsi.com/~stratus, its called 'useradd.sh', instructions for use are inside the file.

As for running it as a user, you can always allow a group of users by looking into 'sudoers', 'sudo' and 'visudo'.

thanks man, but thats not really what i'm looking for i think more user friendly for the users who dont know any thing about arguments
some thing like this

#!/bin/bash

username=" "
clear
echo "Welcome to n3tlab. this program will help you add an account to our system"

echo "What would you like your username to be?"
read username

if test -e /home/$username
then

echo "sorry but that username is in use, please choose another"
read username
echo "now to change your password"
passwd $username
echo "your account has been succesfully created to start using it telnet to us then login with your new account name"
echo "thank you for using n3tlab"
logout

else

echo "ok, your username is $username"
echo "now to change your password"
passwd $username
echo "Your account has succesfully been created, to begin using it telnet to us and login with your account name"
echo "thank you for using n3tlab"
logout
fi

#done

but i need to know a way to make the script work better, with my skills it will only test to see if the user is taken once then, if the user inputs another used username it will try to add the username any ways, can some one help me out with this?

I dont know how you plan on using it, but here:

Code:

#!/bin/bash
SUCESS=
PASS=
username=" "
clear
echo "Welcome to n3tlab. this program will help you add an account to our system"

echo "What would you like your username to be?"
read username

if test -e /home/$username; then
   SUCESS=1
fi

while [ "$SUCESS" = 1 ]
do
  echo "sorry but that username is in use, please choose another"
  read username
  if ! test -e /home/$username; then
    SUCESS=0
  fi
done
echo "choose a password, minimum 8 charators"
read TMP
while [ ${#TMP} -lt 7 ] || [ ${#TMP} -gt 50 ]
do
  if [ ${#TMP} -lt 7 ]; then
    echo "The password needs to be greater than 8 characters" 
    echo "Please input your password..."
  elif [ ${#TMP} -gt 50 ]; then
    echo "Your password needs to be less 50 characters..."
    echo "Please input your password..."
  fi
  read TMP
done
PASS=$(openssl passwd -1 "$TMP")
useradd -p "$PASS" "$username"
echo "your account has been succesfully created to start using it telnet to us then login with your new account name"
echo "thank you for using n3tlab"
logout
exit 0
#done
