如何使用并行ssh运行sudo

Question

Linux: Ubuntu14.04.3 LTS

cat /tmp/passfile
ABCxyz123

sshpass -f /tmp/passfile parallel-ssh -I -A -h hostlist.txt "sudo -S ls -l /root" < /tmp/passfile

在google groups.google中描述的方法将错误输出为：

[1] 01:07:25 [FAILURE] 10.0.4.194 Exited with error code 255
[2] 01:07:25 [FAILURE] 10.0.4.205 Exited with error code 255

在远程服务器中，我试图连接它的/var/log/auth.log有以下消息

Sep 24 19:20:52 ubu1401 sshd[5765]: Accepted password for ubuntu from 10.0.4.1 port 55019 ssh2

Answer 1

您是否尝试过通过回显shell中的密码来运行此操作？

echo "echo 'yourpassword'; sudo -S -c 'ls -l /root'"|pssh -I -H hostlist.txt

我想推荐我的简单工具"spssh.sh“( https://github.com/tangruize/spssh )，它很简单(只有36个sloc)，但是足够有用。与并行ssh不同，spssh.sh是交互式的，并且支持并行/单独的cmd执行。希望能帮上忙！
