get_server_info errors out on pytan 2.0.3 against tanium 6.2

[lespea]

In pytan.sessions.py the function get_server_info it looks like self.http_post is returning a str instead of json:

d == digit; h == hex

dddd-ddddd-hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

This of course is problematic as you can't call get on a unicode string. The library technically continues functioning after the exception is thrown though...

I don't really have access to the Tanium instance but I can try to work with the platform owner if this is unexpected. I did a simple get on /info.json and it looks like the second number increases every time and the last bit is random (I tried hex decoding it but it was gibberish).

[lifehackjim]

Nevermind - just read the subject. Is port 444 open on your firewall for your tanium server? Port 444 is necessary for pytan to access /info (and /info.json) in 6.2

[lespea]

Yeah the connection is made to 444 just fine and everything works it's just returning that weird string instead of json. I hard-coded the "server version" to 6.2 so get_server_info is never called and everything works fine (question fires and returns the expected results).

[lifehackjim]

That's.. odd. I've never seen that. Though that string aligns with what would be a session-id, possibly. I'm about to check in a change to pytan.sessions.Sessions.get_server_info() that makes that function a little more error proof. Mind trying with the develop branch?

[lifehackjim]

Point of note, http_post is SUPPOSED to return a string.

get_server_info() is supposed to parse that string as json into a python dict here: https://github.com/tanium/pytan/blob/2.0.3/lib/pytan/sessions.py#L389

[lespea]

Oh right when I said string I just meant it wasn't a json structure (ie it wouldn't be a dictionary which was expected). I went home for the day but I can checkout the dev branch (just master or is there another one?) and see what happens.

[lifehackjim]

The develop branch is here: https://github.com/tanium/pytan/tree/develop

It contains the next version of PyTan (which is likely to be 2.1.0, although it's currently marked as 2.0.4).

I check in all my changes to develop and once I've fully tested them all, I push to master and do version increments/etc.

[lespea]

Okay cool I'll give it a shot tomorrow and let you know how it goes. Thanks!

[lespea]

Wow that's a lot of documentation in that branch; nice job!

Anyway got this exception now:

info_dict is what you're setting in the json.loads exception body; with a value equal to the string I posted above.

[lifehackjim]

Are you able to webex with me? let's take this direct to email, something is going on that I can't see through what you've provided me.

Fixed in 2.1.0. Thanks!
