ssh登陆不能在命令行中指定密码,也不能以shell中随处可见的,sshpass 的出现,解决了这一问题。它允许你用 -p 参数指定明文密码,然后直接登录远程服务器。 它支持密码从命令行,文件,环境变量中读取
$> sshpass -h Usage: sshpass [-f|-d|-p|-e] [-hV] command parameters
-f filename Take password to use from file
-d number Use number as file descriptor for getting password
-p password Provide password as argument (security unwise)
-e Password is passed as env-var "SSHPASS"
With no parameters - password will be taken from stdin -h Show help (this screen)
-V Print version information
At most one of -f, -d, -p or -e should be used
sshpass [-f|-d|-p|-e] [-hV] command parameters 中的 command parameters 和使用交互式密码验证的使用方法相同
#从命令行方式传递密码
$> sshpass -p user_password ssh user_name@192.168..1.2
$> sshpass -p user_password scp -P22 192.168.1.2:/home/test/t .
#从文件读取密码
$> echo "user_password" > user.passwd
$> sshpass -f user.passwd ssh user_name@192.168..1.2
#从环境变量获取密码
$> export SSHPASS="user_password"
$> sshpass -e ssh user_name@192.168..1.2
对于ssh的第一次登陆,会提示:
“Are you sure you want to continue connecting (yes/no)”,这时用sshpass会不好使,可以在ssh命令后面 -o StrictHostKeyChecking=no
来解决。比如说上面的命令,就可以写作
ssh abc@192.168.1.100 -o StrictHostKeyChecking=no
“Are you sure you want to continue connecting (yes/no)”,这时用sshpass会不好使,可以在ssh命令后面 -o StrictHostKeyChecking=no
来解决。比如说上面的命令,就可以写作
ssh abc@192.168.1.100 -o StrictHostKeyChecking=no
