我需要创建一个自动向OpenSSH ssh客户端输入密码的脚本。
假设我需要使用密码a1234b SSH到myname@somehost。
我已经试过了……
#~/bin/myssh.sh
ssh myname@somehost
a1234b
.．.但这并不奏效。
如何将此功能放入脚本中?

我得到了这个工作如下
.ssh/config被修改以消除是/否提示-我在防火墙后面，所以我不担心欺骗ssh密钥
host *
StrictHostKeyChecking no
为expect创建一个响应文件，即answer.expect
set timeout 20
set node [lindex $argv 0]
spawn ssh root@node service hadoop-hdfs-datanode restart
expect "*?assword {
send "password\r" <- your password here.
interact
创建bash脚本并在文件中调用expect
#!/bin/bash
i=1
while [$i -lt 129] # a few nodes here
expect answer.expect hadoopslave$i
i=[$i + 1]
sleep 5
done
获取128个用新配置刷新的hadoop datanode -假设您正在为hadoop/conf文件使用NFS挂载
希望这能帮助到一些人——我是一个Windows傻瓜，这花了我大约5个小时才弄明白!

# create a file that echo's out your password .. you may need to get crazy with escape chars or for extra credit put ASCII in your password...
echo "echo YerPasswordhere" > /tmp/1
chmod 777 /tmp/1
# sets some vars for ssh to play nice with something to do with GUI but here we are using it to pass creds.
export SSH_ASKPASS="/tmp/1"
export DISPLAY=YOURDOINGITWRONG
setsid ssh root@owned.com -p 22

我设法让它工作了:
SSH_ASKPASS="echo \"my-pass-here\""
ssh -tt remotehost -l myusername
不同的我
sshpass -p PASSWORD ssh USER@SERVER
后缀II
#!/usr/bin/expect -f
spawn ssh USERNAME@SERVER "touch /home/user/ssh_example"
expect "assword:"
send "PASSWORD\r"

如此:
#!/usr/bin/expect -f
spawn ssh USERNAME@SERVER "touch /home/user/ssh_example"
expect "assword:"
send "PASSWORD\r"
interact
但是! !如果出现如下错误，只需使用expect而不是bash启动脚本，如下所示 而不是bash mysh .sh
/bin/myssh.sh: 2: spawn: not found /bin/myssh.sh: 3: expect: not found /bin/myssh.sh: 4: send: not found /bin/myssh.sh: 5: expect: not found /bin/myssh.sh: 6: send: not found
