Can you do an import json and then do a json.dumps(msg_decoded, indent=4)?

Thank you for your reply, I'm sysadmin and I dont know so much about python programming, when i'm trying to do what you say, I'm not able to because the python shell closes after the execution of the script, I tried with subprocess.Popen and os.system from python shell and also doing a script, but the error just closes python without executing the json.dumps.. what can I do?

[russdill]

Put the import line with the other imports, and put the dumps line on the line before the error.

Sorry, forget about the popen thing. Try this script:

https://gist.github.com/russdill/2052a68801bb09925c77

But rather than running it directly, let openconnect run it with --csd-wrapper tncc.py --user-agent "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.1) Gecko/2008071615 Fedora/3.0.1-1.fc9 Firefox/3.0.1" --juniper

This will make it easy to see the output of the script.

I have tried both script with the import and the json.dump but the output its the same with and without the both lines.. the import is placed at the start of the script with the rest of imports, and json.dump is placed in the line 202 I paste you the error with the openconnect:

Traceback (most recent call last): File "tncc.py", line 337, in server.process_cmd() File "tncc.py", line 317, in process_cmd cookie = self.tncc.get_cookie(args['Cookie'], args['DSSIGNIN']) File "tncc.py", line 264, in get_cookie data = self.get_msg_contents(response['msg']) File "tncc.py", line 203, in get_msg_contents compressed = msg_decoded[0x0ce4][0][0x0ce7][0] IndexError: list index out of range Received invalid response from TNCC Failed to obtain WebVPN cookie

The error is exactly the same with both scripts the old and the new one you gave me.. the only change is the line numbers..

[russdill]

My bad, the line should be print json.dumps(msg.decoded, indent=4)

hmmm...after the response = self.parse_response(), can you put a:

print json.dumps(response, indent=4)

Ok, so it's saying policies don't exist for Linux, maybe there is a way to handle that. But can you try a windows user agent string first?

I have changed useragent inside tnnc.py because I was having the same issue just changing it in openconnect and now the output is this one:

ok, now try removing the print json.dumps and see if it works.

Well now I have the following issue.. after request me the login and password I got the following message and ask me again for the password.

Got HTTP response: HTTP/1.1 302 Moved

[russdill]

OK, it's not liking the answer you are giving for the policies. Where it responds to the policies and says 'OK', change the OK to Fail. If this doesn't work, the script may need to start getting smart about which policies to say yes to, and which to say no to.

Well I changed that and now openconnect just crashed:

Connected to HTTPS on vpn.company.com Unknown form ID 'frm' Dumping unknown HTML form:

``` ```

Failed to obtain WebVPN cookie I don't know if this is relevant but the vpn doesn't have policies for linux, to connect from linux I have a tweaked firefox with some .so of windows media player, activex etc.. and with this I bypass the hostchecker and then just copy the DSID and paste it as parameter to a script which contains a openconnect sentence.

[russdill]

I'm guessing the juniper-vpn.py script gives you a "Unknown form type: frm". It looks like it could be a confirmation form though. The forms that openconnect and juniper-vpn.py know about are frmLogin, frmDefender, frmNextToken, and frmConfirmation, so having a form just named 'frm' seems odd. It might be helpful to print out the entire page so it can be seen what it's asking, but the easiest thing is to just try and assume it's a confirmation form. In juniper-vpn.py, in the next_action function where it's testing for what kind of form it is, just change the line:

elif form.name == 'frmConfirmation':

to:

elif form.name == 'frmConfirmation' or form.name == 'frm':

[russdill]

In juniper-vpn.py, uncomment the lines before # Want debugging messages? Also, in the function run (def run(self):), add the lines:

print self.r.info() print self.r.read()

before self.last_action = action

Note in python that indentation is part of the syntax, so be sure they are intended the same number of spaces as the next line. This will likely print a great deal of information and much of it may be personal, so you may need to interpret it and compare what you see with the manual login process on windows.

I am getting this error when I just run

Traceback (most recent call last):

Perhaps it should check that it's invoked with arguments?
