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

@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
我想我没有看到任何人提出这个建议，而操作人员只是说“脚本”，所以……
我需要解决同样的问题，而我最舒服的语言是Python。
我用了paramiko图书馆。此外，我还需要使用sudo发布需要升级权限的命令。事实证明，sudo可以通过“-S”标志通过stdin接受其密码!见下文:
import paramiko
ssh_client = paramiko.SSHClient()
# To avoid an "unknown hosts" error. Solve this differently if you must...
ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
# This mechanism uses a private key.
pkey = paramiko.RSAKey.from_private_key_file(PKEY_PATH)
# This mechanism uses a password.
# Get it from cli args or a file or hard code it, whatever works best for you
password = "password"
ssh_client.connect(hostname="my.host.name.com",
username="username",
# Uncomment one of the following...
# password=password
# pkey=pkey
)
# do something restricted
# If you don't need escalated permissions, omit everything before "mkdir"
command = "echo {} | sudo -S mkdir /var/log/test_dir 2>/dev/null".format(password)
# In order to inspect the exit code
# you need go under paramiko's hood a bit
# rather than just using "ssh_client.exec_command()"
chan = ssh_client.get_transport().open_session()
chan.exec_command(command)
exit_status = chan.recv_exit_status()
if exit_status != 0:
stderr = chan.recv_stderr(5000)
# Note that sudo's "-S" flag will send the password prompt to stderr
# so you will see that string here too, as well as the actual error.
# It was because of this behavior that we needed access to the exit code
# to assert success.
logger.error("Uh oh")
logger.error(stderr)
else:
logger.info("Successful!")
希望这能帮助到一些人。我的用例是在大约300台服务器上创建目录、发送和解压文件以及启动程序。因此，自动化至关重要。我试过sshpass, expect，然后想到了这个。
在脚本中使用脚本tossh，第一个参数是主机名，第二个参数是密码。
#!/usr/bin/expect
set pass [lindex $argv 1]
set host [lindex $argv 0]
spawn ssh -t root@$host echo Hello
expect "*assword: "
send "$pass\n";
interact"
在下面的例子中，我将写下我使用的解决方案:
场景:我想用sh脚本从服务器复制文件:
#!/usr/bin/expect
$PASSWORD=password
my_script=$(expect -c "spawn scp userName@server-name:path/file.txt /home/Amine/Bureau/trash/test/
expect \"password:\"
send \"$PASSWORD\r\"
expect \"#\"
send \"exit \r\"
")
echo "$my_script"
