I'm trying to bind to a LDAP server using the ldap library in Python. However, every time I try to use sasl_interactive_bind_s() in Python, I get the following error:
AttributeError: sasl_interactive_bind_s
I don't know why this is happening, and the error message isn't very helpful either. Here is the code I'm using. (dc.hostname is just the server name)
conn = ldap.initialize("ldap://" + dc.hostname + ":3268")
conn.set_option(ldap.OPT_NETWORK_TIMEOUT, 5)
conn.set_option(ldap.OPT_PROTOCOL_VERSION, ldap.VERSION3)
conn.set_option(ldap.OPT_REFERRALS, ldap.OPT_OFF)
conn.set_option(ldap.OPT_RESTART, ldap.OPT_ON)
sasl_cb_value_dict = {}
sasl_cb_value_dict[ldap.sasl.CB_AUTHNAME] = bind_dn
sasl_cb_value_dict[ldap.sasl.CB_PASS] = admin_pw
auth_tokens = ldap.sasl.sasl(sasl_cb_value_dict,"DIGEST-MD5")
conn.sasl_interactive_bind_s("", auth_tokens)
In order to try and circumvent this, I also tried to bind using the C function ldap_sasl_bind_s() and this helped bind successfully. But, now I don't know how to pass this connection object back to Python, so that I can query the LDAP server. (Note: I used the ldap_search_ext_s() function in C, but that never really returned anything, because it took too long to query)
Any help/advice would be greatly appreciated. Thanks in advance!

I am wondering anyone can help me in one of the thing I cannot get my around it and really bothering as I spent last two on it but couldnt make it.
Basically, I am building an App (Django Python) to restore the information regarding all the network device e.g hostname, IP Address, S/N, Rack info etc. but I also to enable few options like Add, Edit, Delete and Connect next to device entery. I was able to create all the options except Connect option where I am completely stuck, I am trying to query database to get the IP address information and then using Popen module to open a putty window with the ssh to that IP Address device related, I tried everything I could but nothing worked, thereofrore, asking your help if you have any idea about this ? or any other alternative method for a user when he click on connect the putty or similar app will open and he just put the login credentials and get into the device.
I am sharing my code here, let me know if I am doing something wrong.
on the show all device page, i have this code, show.html
<td>Connect</td>
<!--<td>Connect</td>-->
I tried both ways, with id and ip address entry in the database
on view.py
def connect(request, ip_address):
hostlist_ip = HostList.ip_address
print(hostlist_ip)
Popen("putty.exe" + hostlist_ip)
return redirect('/show')
and in the url.py
path('connect/<str:ip_address>', views.connect),
or
path('connect/<str:ip_address>', views.connect),
Since I am also printing the the output on the terminal I notice that it is not returning the actually IP address but return this;
<django.db.models.query_utils.DeferredAttribute object at 0x04B77C50>
and on the web I receiving this error
TypeError at /connect/10.10.32.10
can only concatenate str (not "DeferredAttribute") to str
Request Method: GET
Request URL: http://localhost:8000/connect/10.10.32.10
Django Version: 2.2.3
Exception Type: TypeError
Exception Value:
can only concatenate str (not "DeferredAttribute") to str
let me know if you can help.
Just a F.Y.I I already tested the Popen via python but since we not getting the actual IP address from the database I am seeing this and I am a complete newbie with html/css and Djano, however I have some basic knowledge of python, so please ignore my any stupid comments in the post.
Many thanks
ahh I cannot believe I spend two day to troubleshoot this and just changed the name from ip_address to ip_add and it is working now :) i think as I mentioned above in the comment, it probably confusing with the built in module
here is simple solution:
views.py
def connect(request, ip_add):
import os
from subprocess import Popen
Popen("powershell putty.exe " + ip_add)
return redirect('/show')
url.py
path('connect/<str:ip_add>', views.connect),
I may have to find out a way if user is using the mac or linux, how I am going to change this powershell to something else. but anyhow it is working for windows
thanks all for the responses.
I'm fairly new to Python and would like some guidance on how to deal with authentication errors with urrlib3 on Python 2.7. My current use case is using SNAPI to auto create ServiceNow tickets. To do this I have the following snippet of code to use my username/password and get a token to log in.
r = session.post(auth_url, json=login_data, verify=False)
web_token = r.text
This is working fine but I want a cleaner way of notifying myself if there is an error within the code. If the username/password is incorrect, I get this back from the SN web server.
{
"error": "Authentication failure"
}
Originally I was going to use a try/exception but it seems like that wouldn't work very well in this case since the code is working correctly, it's just not the input I was expecting. So my second thought was doing something along the lines of:
if r.text does not contain "error"
then continue on my doe
else send an email telling me the error code
Before writing the code for that, I wanted to see if this is the best method for this type of error handling or if I should be going down another route.
Thanks,
Eric
I spoke with a friend and he recommended the following method which seems to work very well and is a lot cleaner than doing an if/match statement.
try:
r = session.post(auth_url, json=login_data, verify=False)
web_token = r.text
r.raise_for_status()
except Exception as e:
print(e)
I am new to C# and would be really grateful if someone could provide some insight on the following problem: I have written a c# app that gets the html content of a website, quite simply using a webclient. The problem is that if I run it for multiple websites I see that sometimes I get no results for some of them, like it was never connected to that website at that instance. I initially thought it was my internet connection but the same happened when I tried on a different wifi. It is worth mentioning that I have the same prob on another of my appcs when trying to connect to a webservice. My question is: does anybody know how can this be fixed? Does it have to do with the timeout time of something like that?
Thank you very much in advance
This is the code but it's not really an issue of coding:
var client = new WebClient();
try
{
var htmlcode = client.DownloadString(site);
int NumberOfTrues = Regex.Matches(htmlcode.ToLower(), key).Count;
}
catch (Exception)
{
messagebox.show("could not be loaded");
}
This was solved by defining the default proxy server in app config.
I am new to the wsdl\soapmessage query\reply world( if i can put it in this way), and I am facing some difficulties using the following wsdl( which I really really hope, one will be so kind to look at at least one of the services described there)
http://almdemo.polarion.com/polarion/ws/services/TrackerWebService?wsdl
which was provided to me to develop a matlab webinterface. Right now my matlab code looks like this:
targetNamespace = 'http://ws.polarion.com/TrackerWebService';
method = 'queryWorkItems';
values= {'Query','Sort'}
names = {'query', 'sort'}
types ={'xsd:string','xsd:string'}
message = createSoapMessage( targetNamespace, method, values, names, types)
response = callSoapService('http://almdemo.polarion.com/polarion/ws/services',...
% Service's endpoint
'http://almdemo.polarion.com/polarion/#/workitems',...
% Server method to run
message)
% SOAP message created using createSoapMessage
author = parseSoapResponse(response)
Herewith to save you time I will just enonce my two problems:
Is the code correct?
Could someone tell me if such a wsdl link is just a definition of webservices or it is also a service's endpoint?
Normally to execute manually\per clicks this services on the weppage
http://almdemo.polarion.com/polarion, you have to login!
So how do I send a message in matlab which first log me in? Or must such a service be introduced into that wsdl for me to do it?? Could you be kind enough to write how it must be defined, because I don't really
write wsdl files, but I shall learn!**
I will be really thankful for your help and I wish you a happy week(-end) guys(& girls)!!!
Regards
Chrysmac
ps: I tried to use Soapui and gave that webpage as endpoint, but the toool crashes each time I enter my credentials! Maybe because of the dataload!??
How can I make the login part in QuickFIX in c++?
I found tons of tutorials and articles on how to do this on c# or java, but nothing on c++.
I have a server (acceptor), and a client (initiator). The username and password of the client are stored in the settings file, and are hardcoded in the server program.
From what I've read in the client I set the username and password in fromAdmin() and read and check the in the server in the toAdmin(), but how do I do that?
Here's what I've tried so far:
cast the message to a FIX44::Logon& object using:
FIX44::Logon& logon_message = dynamic_cast<FIX44::Logon&>(message);
Set the Username and password to the logon object like this:
if(session_settings.has("Username"))
{
FIX::Username username = session_settings.getString("Username");
logon_message.set(username);
}
And send the message like this:
FIX::Message messageToSend = logon_message;
FIX::Session::sendToTarget(messageToSend);
But I get this error on the cast:
cannot dynamic_cast 'message' (of type 'class FIX::Message') to type 'struct FIX44::Logon&' (target is not pointer or reference to complete type)
What I've tried I got inspired from http://niki.code-karma.com/2011/01/quickfix-logon-support-for-username-password/comment-page-1/.
I'm still not clear on how to make the client and the server.
Can anyone help me?
Possible mistakes:
I think you have fromAdmin()/toAdmin() backward. toAdmin() is called on outgoing admin messages, fromAdmin() is called on incoming. For the Initiator, you must set the fields within the toAdmin() callback. Your Acceptor will check the user/pass in fromAdmin().
Are you trying to dynamic_cast without first checking to see if it was a Logon message? The toAdmin() callback handles all admin messages; the message could be a Heartbeat, Logon, Logout, etc. That might explain your cast error.
As to what the code should look like, my C++ is rusty, but the basic pattern is this:
void YourMessageCracker::toAdmin( FIX::Message& message, const FIX::SessionID& sessionID)
{
if (FIX::MsgType_Logon == message.getHeader().getField(FIX::FIELD::MsgType))
{
FIX44::Logon& logon_message = dynamic_cast<FIX44::Logon&>(message);
logon_message.setField(FIX::Username("my_username"));
logon_message.setField(FIX::Password("my_password"));
}
}
From there, I think you can see how you'd write a similar fromAdmin() where you'd get the fields instead of setting them.
The above uses hard-coded user/pass, but you probably want to pull it from the config file. I think your calls to session_settings.getString(str) are correct for that.
(Please forgive any coding errors. I'm much more fluent in the Java/C# versions of the QF engine, though the basic principles are the same.)
I see that your first web reference uses the FIELD_GET_REF macro. It may be better than message.getHeader().getField(), but I'm not familiar with it.
