sshfs 在期望脚本中不使用密码
我编写了一个小脚本来向 sshfs 提供密码,但由于某种原因 sshfs 没有获取密码。有什么指点吗? (PS,我知道 ssh 密钥更好/更安全,但我工作的政治环境阻止在目标服务器上设置基于密钥的身份验证 - 叹息......)。
#!/usr/bin/expect
# NOT WORKING!!
exp_internal 1
spawn sshfs server:/export/pc_storage /home/sonia/mnt/server
expect {
"assword:" {
send "secret\r\r"
send_user "\n"
}
timeout {
send_user "timed out!\n"
}
}
为了终止密码,我尝试了 \r \n \r\r - 没有效果。
调试输出,显示密码提示正在触发:
spawn sshfs server:/export/pc_storage /home/sonia/mnt/server
parent: waiting for sync byte
parent: telling child to go ahead
parent: now unsynchronized from child
spawn: returns {17532}
expect: does "" (spawn_id exp6) match glob pattern "assword:"? no
pcuser@server's password:
expect: does "pcuser@server's password: " (spawn_id exp6) match glob pattern "assword:"? yes
expect: set expect_out(0,string) "assword:"
expect: set expect_out(spawn_id) "exp6"
expect: set expect_out(buffer) "pcuser@server's password:"
send: sending "secret\r\r" to { exp6 }

已解决:(
我无法发布答案,因为我没有 100 分 - 双重叹息)
我需要稍微修复一下...例如,我将 PS1 硬编码为我的 .bashrc 为“bash_prompt”(我默认使用 zsh)。
#!/usr/bin/expect
# FIX: get homedir from env, set bash prompt somehow...
set timeout 30
spawn /bin/bash
expect "bash_prompt"
send_user "Shell spawned.\n"
send -- "sudo umount /home/sonia/mnt/server &> /dev/null\r"
expect "bash_prompt"
send -- "sshfs server:/export/pc_storage /home/sonia/mnt/server\r"
expect {
"assword:" {
send "secret\r"
send_user "\n"
}
timeout {
send_user "timed out!\n"
}
}
expect "bash_prompt"
I've written a little script to supply a password to sshfs, but for some reason sshfs isn't grabbing the password. Any pointers? (PS I know ssh keys are better/safer, but politics where I work prevents key based authentication being setup on the target server - sigh... ).
#!/usr/bin/expect
# NOT WORKING!!
exp_internal 1
spawn sshfs server:/export/pc_storage /home/sonia/mnt/server
expect {
"assword:" {
send "secret\r\r"
send_user "\n"
}
timeout {
send_user "timed out!\n"
}
}
To terminate the password, I've tried \r \n \r\r - none work.
Debugging output, showing that password prompt is triggering:
spawn sshfs server:/export/pc_storage /home/sonia/mnt/server
parent: waiting for sync byte
parent: telling child to go ahead
parent: now unsynchronized from child
spawn: returns {17532}
expect: does "" (spawn_id exp6) match glob pattern "assword:"? no
pcuser@server's password:
expect: does "pcuser@server's password: " (spawn_id exp6) match glob pattern "assword:"? yes
expect: set expect_out(0,string) "assword:"
expect: set expect_out(spawn_id) "exp6"
expect: set expect_out(buffer) "pcuser@server's password:"
send: sending "secret\r\r" to { exp6 }

SOLVED:
(I can't post an answer as I don't have 100 points - double sigh)
I need to fix this up a bit... For example I hard coded PS1 in my .bashrc to "bash_prompt" (I use zsh by default).
#!/usr/bin/expect
# FIX: get homedir from env, set bash prompt somehow...
set timeout 30
spawn /bin/bash
expect "bash_prompt"
send_user "Shell spawned.\n"
send -- "sudo umount /home/sonia/mnt/server &> /dev/null\r"
expect "bash_prompt"
send -- "sshfs server:/export/pc_storage /home/sonia/mnt/server\r"
expect {
"assword:" {
send "secret\r"
send_user "\n"
}
timeout {
send_user "timed out!\n"
}
}
expect "bash_prompt"

您可以直接提供密码,而不是使用 Expect。
尝试一下:
不确定您是否可以使用您的密码策略来实现此功能,但值得一试。
Rather than use Expect, you can just supply the password directly.
Try this:
Not sure if you can make this work with your password policies, but its worth a shot.

似乎不对。您尝试过\r\n
吗?\r\r
does not seem right. Have you tried\r\n
?
