Bulk upload SSH public key

Bulk upload SSH public key

The vicissitudes of the first world

First you need to install Python

Yum Install Python-y

Write a Python script like this:

#vi ssh.py

#!/usr/bin/python

Import Sys

Import Pexpect

ip = sys.argv[1]

Password = sys.argv[2]

Expect_list = [' (yes/no) ', ' Password: ']

p = pexpect.spawn (' ssh-copy-id%s '% IP) # #如果公钥不是在默认位置的话, change the Ssh-copy-id to ssh-copy-id-i public key location.

Try

While True:

IDX = P.expect (expect_list)

Print P.before + Expect_list[idx],

If idx = = 0:

Print "Yes"

P.sendline (' yes ')

elif idx = = 1:

Print password

P.sendline (password)

Except Pexpect. TIMEOUT:

Print >>sys.stderr, ' timeout '

Except Pexpect. Eof:

Print P.before

Print >>sys.stderr, ' <the end> '

(Single use method: use: Python ssh.py 192.168.2.10 password1 #用户名和密码没错一般都可以. ）

2: Python combined with shell for bulk upload

The IP and password of the server are listed in a TXT file, for example (a.txt):

192.168.1.1 Password1

192.168.1.2 Password2

192.168.1.3 Password3

Then call the following with the shell script

[Email protected] opt]# VI ssh.sh

Cat A.txt |while Read line; Do

Ip= ' echo $line | awk ' {print '} '

Passwd= ' echo $line | awk ' {print $} '

Python ssh.py $ip $passwd

Done

Finally executed./ssh.sh

If there is an error

is because the Pexpect module that does not have Python installed is installed as follows:

Pexpect Module Installation

Pexpect belongs to a third party, so it needs to be installed,

The current version is 3.3 https://pypi.python.org/pypi/pexpect/

Installation steps:

　　　　

TAR-XZVF pexpect-3.3.tar.gz

CD pexpect-3.3

Python setup install (require root)

However, this installation requires root privileges, and if there is no root authority, can it be used?

The answer is yes, you just need to put the path of Lib into Sys.path. This allows you to use the Pexpect

#!/usr/bin/env python

Import Sys

Sys.path.append (' Pexpect-3.3/build/lib ')

Confirm Installation Success:

　　　　

>>> Import Pexpect

>>> dir (pexpect)

[' EOF ', ' exceptionpexpect ', ' PY3 ', ' TIMEOUT ', ' __all__ ', ' __builtins__ ', ' __doc__ ', ' __file__ ', ' __name__ ', ' __package_ _ ', ' __path__ ', ' __revision__ ', ' __version__ ', ' _run ', ' codecs ', ' errno ', ' fcntl ', ' is_executable_file ', ' OS ', ' Pty ', ' re ', ' Resource ', ' Run ', ' Runu ', ' searcher_re ', ' searcher_string ', ' select ', ' signal ', ' spawn ', ' spawnu ', ' split_command_ ' Line ', ' stat ', ' struct ', ' sys ', ' termios ', ' time ', ' traceback ', ' tty ', ' types ', ' which ']

As noted above, it is important to note:

A.txt format, the first parameter is IP, the second is the password. The middle is separated by a space, generally use this on the bulk upload public key to the server is no problem.

If the public key is not in the default location, the statement in the Python script, p = pexpect.spawn (' ssh-copy-id%s '% IP), changes the Ssh-copy-id to ssh-copy-id-i public key location.

In addition, the above program before running to be a public key and password ssh-keygen-t RSA (two-time return)
