sshpass: 用于非互動的ssh 密碼驗證
ssh登陸不能在指令行中指定密碼,也不能以shell中随處可見的,sshpass 的出現,解決了這一問題。它允許你用 -p 參數指定明文密碼,然後直接登入遠端伺服器。 它支援密碼從指令行,檔案,環境變量中讀取
$> 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 和使用互動式密碼驗證的使用方法相同
#從指令行方式傳遞密碼
$> sshpass -p user_password ssh [email protected]
$> sshpass -p user_password scp -P22 192.168.1.2:/home/test/t .
#從檔案讀取密碼
$> echo "user_password" > user.passwd
$> sshpass -f user.passwd ssh [email protected]
#從環境變量擷取密碼
$> export SSHPASS="user_password"
$> sshpass -e ssh [email protected]
