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?

当前回答
您可以使用expect脚本。我没有写一个在相当长的一段时间,但它应该如下所示。您需要在脚本前面加上#!/usr/bin/expect
#!/usr/bin/expect -f
spawn ssh HOSTNAME
expect "login:"
send "username\r"
expect "Password:"
send "password\r"
interact
其他回答
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
这是我登录服务器的方式:
ssp <server_ip>
别名ssp = ' / home / myuser /文件/ ssh_script.sh” 猫/home/myuser/Documents/ssh_script.sh
ssp:
#!/bin/bash
sshpass -p mypassword ssh root@$1
因此:
ssp server_ip
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。
首先需要安装sshpass。
Ubuntu/Debian: apt-get安装sshpass Fedora/CentOS: yum安装sshpass Arch:吃豆人-S sshpass
例子:
sshpass -p "YOUR_PASSWORD" ssh -o StrictHostKeyChecking=no YOUR_USERNAME@SOME_SITE.COM
自定义端口示例:
sshpass -p "YOUR_PASSWORD" ssh -o StrictHostKeyChecking=no YOUR_USERNAME@SOME_SITE.COM:2400
注:
当传递-f标志时,Sshpass还可以从文件中读取密码。 使用-f可以防止在执行ps命令时密码显示。 存储密码的文件应具有安全权限。
这应该在大多数情况下都有帮助(你需要先安装sshpass !):
#!/usr/bin/bash
read -p 'Enter Your Username: ' UserName;
read -p 'Enter Your Password: ' Password;
read -p 'Enter Your Domain Name: ' Domain;
sshpass -p "$Password" ssh -o StrictHostKeyChecking=no $UserName@$Domain
