[英]Connect CISCO Anyconnect VPN via Python
I am trying to connect to CISCO Anyconnect VPN via python function. 我正在尝试通过python函数连接到CISCO Anyconnect VPN。 I have seen the ways given here: Connect CISCO Anyconnect VPN via bash
我已经看到了这里给出的方法: 通过bash连接CISCO Anyconnect VPN
But first I have a couple of problems, the first one being new to Python and second being reluctant to use any/very-few third-party modules/libraries other than https://github.com/cernekee/stoken . 但是首先我有两个问题,第一个是Python的新问题,第二个是不愿意使用https://github.com/cernekee/stoken以外的任何/很少的第三方模块/库。
Here, stoken gives me the RSA SecureID token for authentication when I run:
在这里,当我运行时, stoken为我提供了用于认证的RSA SecureID令牌:
$ stoken tokencode
My password consists of a 4-digits pin say, WXYZ which is concatenated with the RSA token for the passcode input.
我的密码包含一个4位数的密码,即WXYZ ,该密码与用于输入密码的RSA令牌串联。
I came up with the following one-liner bash command to connect which works so far from my OSX: 我想出了以下单线bash命令进行连接,该命令到目前为止与OSX无关:
'(echo "user.name";echo "WXYZ$(stoken tokencode)"; echo y )> vps.ad ; /opt/cisco/anyconnect/bin/vpn -s connect "vpn.domain" < vps.ad'
Now, in my python script, I tried using both os and
subprocess modules to do the same but failed spectacularly.
现在,在我的python脚本中,我尝试同时使用os和
子进程模块来执行相同操作,但是失败了。
I have several VPN domains and two different pins(like, WXYZ) which I am trying to put together to replicate the above bash command. 我有几个VPN域和两个不同的引脚(例如WXYZ),我试图将它们放在一起以复制上述bash命令。 The function now looks like this:
该函数现在如下所示:
def __auth_cisco_vpn__(username, pin, domain):
try:
token = str(os.popen('stoken tokencode', 'r'))
pre_prcs = '(echo "' + username + '";echo "' + pin + '$(stoken tokencode)"; ' + 'echo y )> vps.ad ; /opt/cisco/anyconnect/bin/vpn -s connect "' + domain + '" < vps.ad'
subprocess.Popen(pre_prcs, shell=True, executable="/bin/bash", stdout=subprocess.PIPE,
stderr=subprocess.PIPE).communicate()
return True
except KeyboardInterrupt:
return False
I managed to get the following error when I try to get the token separately as below: 当我尝试分别获取令牌时,出现以下错误:
pre_prcs = '(echo "'+username+'";echo "'+pin+'$'+token+'"; ' + 'echo y )> vps.ad ; /opt/cisco/anyconnect/bin/vpn -s connect "'+domain+'" < vps.ad'
subprocess.Popen(pre_prcs, shell=True, executable="/bin/bash", stdout=subprocess.PIPE, stderr=subprocess.PIPE).communicate()
TypeError: cannot concatenate 'str' and 'file' objects TypeError:无法连接“ str”和“ file”对象
What should I do? 我该怎么办? Many thanks in advance.
提前谢谢了。
After a little tweaking, I found out the problem and come up with the following solution. 稍作调整后,我发现了问题并提出了以下解决方案。 Notice the error with the quotations in
# Assign cmd section below:
请注意以下“ #分配cmd”部分中的引号引起的错误:
import subprocess
def __auth_cisco_vpn__(username, pin, domain):
# Grab Token
proc = subprocess.Popen(['stoken', 'tokencode'],
stdout=subprocess.PIPE,
stderr=subprocess.PIPE)
store = list(proc.stdout)
token = store[0].strip()
# Assign cmd
credentials = "printf '" + username + "\\n" + pin + token + "\\ny'"
vpn_cmd = "/opt/cisco/anyconnect/bin/vpn -s connect '" + domain + "'"
cmd = credentials + " | " + vpn_cmd
# Command Execution
print("Executing Command: \n" + cmd)
subprocess.Popen(cmd,
shell=True,
executable="/bin/bash",
stdout=subprocess.PIPE,
stderr=subprocess.PIPE).communicate()
__auth_cisco_vpn__('user.name', 'WXYZ', 'domain')
