批量添加用户

为 vps 批量添加用户,为该用户的ssh,vpn,ftp服务提供统一的帐号密码。

使用方法

$ ./adduser.sh 	# 从users.list文件读入用户名，并为该用户名生成users.XXXX形式的密码(XXXX为随机数)
$ ./addvpn.sh 		# 从users.list文件读入用户名和密码, 同步到 /etc/ppp/chap-secrets 文件.

命令脚本

#
#users.list
#
user1
user2
user3
user4

#
# adduser.sh
#

#!/bin/bash

ERROR () {
echo "error occur: $1"
exit 1

}


LIST="./users.list"
PASSWD="./passwd.exp"
export IFS=':'

#set -x
[[ $UID -ne 0 ]] && echo "Permission deny" && exit 1

while read login passwd; do
if [[ -z $passwd ]] ; then
echo "Add account: $login..."
useradd -N -m  -G sshd -s /bin/false $login || ERROR "useradd failed"
passwd=$(mktemp -u ${login}.XXXX)
$PASSWD $login $passwd || ERROR "$PASSWD failed"
sed -i  "s/${login}.*/$login:$passwd/" $LIST
echo "--------------------"
fi
done < $LIST

#

#

#!/usr/bin/expect -f

# ./passwd.exp $login $passwd

set password [lindex $argv 1]
set login [lindex $argv 0]

set ret 0
set timeout 3

spawn passwd $login
expect "*password:"
sleep 1
send "$password\r"
expect "*password:"

send "$password\r"

expect {
"*successfully" {
send_user "# passwd $login $password  Okay\n"
}
timeout {
send_user "PASSWD error";
set ret 1
}
}


exit $ret
