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

使用公钥认证:https://help.ubuntu.com/community/SSH/OpenSSH/Keys
在源主机中只运行一次:
ssh-keygen -t rsa # ENTER to every field
ssh-copy-id myname@somehost
这就是全部，之后你就可以不用密码使用ssh了。
如此:
#!/usr/bin/expect -f
spawn ssh USERNAME@SERVER "touch /home/user/ssh_example"
expect "assword:"
send "PASSWORD\r"

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

# 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

在ubuntu linux -
ssh username@server_ip_address -p port_number
按enter键，然后输入服务器密码
如果您不是root用户，请在命令的开头添加sudo
