服务器评测
这是一个使用shell和expect无需做任何配置一键就实现批量分发密钥和文件的脚本：
#!/bin/bash
# this scripts comes from linuxidc trainning’s student.
# function: remote dis ssh key.
# version:1.1
. /etc/init.d/functions
file=”$1″
remote_dir=”$2″
if [[ $# -ne 2 ]];then
echo “usage:$0 argv2”
echo “must have one argvs”
exit
fi
function KNOWN_HOST_REBUILD()
{
#确保本机存在known_hosts列表
[ ! -e ~/.ssh/known_hosts ] && mkdir -p ~/.ssh/ && touch ~/.ssh/known_hosts
local i=$1
sed -i “/^${i} /d” ~/.ssh/known_hosts
expect -c ”
spawn /usr/bin/ssh linuxidc@${i} echo ok;
expect \”*yes/no)?\”;
send \”yes\r\”;
expect eof ” >/dev/null 2>&1
return 0
[[ $? -ne 0 ]] && echo “$i know host rebuild fail,maybe the server connect error”
}
function PASS_PASSWD()
{
ip=$1
expect -c ”
set timeout -1
spawn ssh-copy-id -i id_dsa linuxidc@$ip
expect \”*password:\”

}
