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?

# 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

其他回答
Sshpass + autossh
前面提到的sshpass的一个好处是，您可以将它与autossh一起使用，从而消除了更多交互效率低下的问题。
sshpass -p mypassword autossh -M0 -t myusername@myserver.mydomain.com
这将允许自动重新连接，如果你的wifi被打断，关闭你的笔记本电脑。
有一个跳转主机
sshpass -p `cat ~/.sshpass` autossh -M0 -Y -tt -J me@jumphost.mydomain.com:22223 -p 222 me@server.mydomain.com
在寻找这个问题的答案几个月后，我终于找到了一个更好的解决方案:写一个简单的脚本。
#!/usr/bin/expect
set timeout 20
set cmd [lrange $argv 1 end]
set password [lindex $argv 0]
eval spawn $cmd
expect "password:"
send "$password\r";
interact
把它放在/usr/bin/exp，所以你可以使用:
Exp <password> SSH <任何> Exp <password> SCP <anysrc> <anydst>
完成了!
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
@abbotto的答案对我不起作用，不得不做一些不同的事情:
Yum install sshpass更改为- RPM -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/sshpass-1.05-1.el6.x86_64.rpm 使用sshpass的命令修改为- sshpass -p "pass" SSH user@mysite -p 2122
# 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
