sshpass之非交互SSH密碼驗證
阿新 • • 發佈：2017-11-29
sshpass SSH登陸不能在命令行中指定密碼。sshpass用於非交互SSH的密碼驗證，一般用在shell腳本中，無須手動輸入密碼。它允許你用 -p 參數指定明文密碼，然後直接登錄遠程服務器，它支持密碼從命令行、文件、環境變量中讀取。
一、安裝sshpass:
1. 通過源碼編譯安裝
# http://sourceforge.net/projects/sshpass/ 下載地址 $ tar -zxvf sshpass-xx.tar.gz $ ./configure $ make && make install
2. 通過源服務器安裝
$ sudo apt-get install sshpass
二、使用sshpass
1. 登錄遠程服務器
$ sshpass -p password ssh username@ip_addr
2. scp上傳或下載文件
$ sshpass -p password scp username@ip_addr:/remote_dir /local_dir $ sshpass -p password scp /local_dir username@ip_addr:/remote_dir
3. sshpass命令詳細用法
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 -P prompt Which string should sshpass search for to detect a password prompt -v Be verbose about what you're doing -h Show help (this screen) -V Print version information At most one of -f, -d, -p or -e should be used
