Can't connect to SugarCRM Soap API - soap

I've just started on a project where I need to insert contacts into a SugarCRM system using the SOAP interface.
So far I have created a reference to the service http://sugar-dev.walkinwifi.net/soap.php?wsdl=sugarsoap
Then writen some code like this
public SugarHelper()
{
//Create a new instance of the client proxy
this.sugarClient = new sugarsoapPortTypeClient();
//Set the default value
this.sessionId = String.Empty;
}
public bool Authenticate(string Username, string Password)
{
//Create an authentication object
user_auth user = new user_auth();
//Set the credentials
user.user_name = Username;
user.password = this.computeMD5String(Password);
//Try to authenticate
set_entry_result authentication_result = this.sugarClient.login(user, "");
this gives you the jest.
The last line gives me an exception when login is called.
The exception I get has an inner exception complaining it can't connect to https://sugar-dev.walkinwifi.net/soap.php
{"An error occurred while making the HTTP request to https://sugar-dev.walkinwifi.net/soap.php. This could be due to the fact that the server certificate is not configured properly with HTTP.SYS in the HTTPS case. This could also be caused by a mismatch of the security binding between the client and the server."}
Where does the https part come from? I have used no other reference other than http yet the error clearly states https.
Can I connect to SugarCRM soap via http or must I use https?
In all the examples I can find on the net it's http but most of them are php with very c# ones.

I'm looking in the wrong place. Inside the Soap configuration of Sugar you specify the url that will be used for soap calls. This is set to https://sugar-dev.walkinwifi.com.
Changed it to http and all is well.

In any case, the SOAP services must also work over HTTPS. Personally I have not had any problems, even with a C # client. Verify that the server certificate and the certificate chain are valid.
Bye,
Antonio.

Hashicorp Vault Kerberos Auth with VaultSharp

I'm having great difficulty getting Kerberos Auth working with Vault using VaultSharp.
I don't have control over Vault server but I've been informed that it is configured and ready to use.
I'm using .NET running in IIS and I want to make use of the service account that IIS is running under so that I don't need to store additional secrets or user/passwords.
Here is the code I'm using and the error:
public string GetSecretWithKerberosAuthUsingVaultSharp(string keyName, string vaultBaseAddress, string vaultResourcePath, string mountPoint)
{
IAuthMethodInfo authMethod = new KerberosAuthMethodInfo(); // uses network credential by default.
var vaultClientSettings = new VaultClientSettings(vaultBaseAddress, authMethod);
IVaultClient vaultClient = new VaultClient(vaultClientSettings);
var result = vaultClient.V1.Secrets.KeyValue.V2.ReadSecretAsync(vaultResourcePath, mountPoint: mountPoint).Result;
//Above line gives this error message:
//{"request_id":"a85dfbb3-b283-3513-7cd3-01ad757eed1b","lease_id":"","renewable":false,"lease_duration":0,"data":null,"wrap_info":null,"warnings":["Unauthorised.\n\n"],"auth":null}
var resultData = result.Data;
string secret = resultData.Data[keyName].ToString();
return secret;
}
I have managed to get it working using token auth as well as through the CLI but that is not quite what I want.
authMethod.Credentials.UserName/Domain both are empty strings.
Don't know if they are supposed to be populated in this case or not but documentation states that it "uses network credentials by default"
Any help appreciated.
Is your web application running in integrated Windows Auth mode, with anonymous auth disabled?
If no, please make it work in that mode for your web app to have the Windows Integrated Auth context so that web calls from VaultSharp to Vault API can have the security context.
If yes, then can you please try a couple of things?
var kerberosAuthInfo = new KerberosAuthMethodInfo(CredentialCache.DefaultCredentials);
If the above doesn't work, then can you try explicit credentials.
var kerberosAuthInfo = new KerberosAuthMethodInfo(new NetworkCredential(userName, password, domain));
Ideally, the web app context should carry the integrated windows context so that you don't need to provide explicit credentials, but it might be worth trying to ensure that it works first and then we can backtrack as to why the context is not being passed.

Postman : socket hang up

I just started using Postman. I had this error "Error: socket hang up" when I was executing a collection runner. I've read a few post regarding socket hang up and it mention about sending a request and there's no response from the server side and probably timeout. How do I extend the length of time of the request in Postman Collection Runner?
For me it was because my application was switched to https and my postman requests still had http in them. Changing postman to https fixed it.
Socket hang up, error is port related error. I am sharing my experience. When you use same port for connecting database, which port is already in use for other service, then "Socket Hang up" error comes out.
eg:- port 6455 is dedicated port for some other service or connection. You cannot use same port (6455) for making a database connection on same server.
Sometimes, this error rises when a client waits for a response for a very long time. This can be resolved using the 202 (Accepted) Http code. This basically means that you will tell the server to start the job you want it to do, and then, every some-time-period check if it has finished the job.
If you are the one who wrote the server, this is relatively easy to implement. If not, check the documentation of the server you're using.
Postman was giving "Could not get response" "Error: socket hang up".
I solved this problem by adding the Content-Length http header to my request
Are you using nodemon, or some other file-watcher? In my case, I was generating some local files, uploading them, then sending the URL back to my user. Unfortunately nodemon would see the "changes" to the project, and trigger a restart before a response was sent. I ignored the build directories from my file-watcher and solved this issue.
Here is the Nodemon readme on ignoring files: https://github.com/remy/nodemon#ignoring-files
I have just faced the same problem and I fixed it by close my VPN. So I guess that's a network agent problem. You can check if you have some network proxy is on.
this happaned when client wait for response for long time
try to sync your API requests from postman
then make login post and your are done
I defined Authenticate method to generate a token and mentioned its return type as nullable string as:
public string? Authenticate(string username, string password)
{
if(!users.Any(u => u.Key==username && u.Value == password))
{
return null;
}
var tokenHandler = new JwtSecurityTokenHandler();
var tokenKey = Encoding.ASCII.GetBytes(key);
var tokenDescriptor = new SecurityTokenDescriptor()
{
Subject = new ClaimsIdentity(new Claim[]
{
new Claim(ClaimTypes.Name, username)
}),
Expires = DateTime.UtcNow.AddHours(1),
SigningCredentials = new SigningCredentials(new
SymmetricSecurityKey(tokenKey),
SecurityAlgorithms.HmacSha256Signature)
};
var token = tokenHandler.CreateToken(tokenDescriptor);
return tokenHandler.WriteToken(token);
}
Changing nullable string to simply string fixed "Socket Hang Up" issue for me!
If Postman doesn't get response within a specified time it will throw the error "socket hang up".
I was doing something like below to achieve 60 minutes of delay between each scenario in a collection:
get https://postman-echo.com/delay/10
pre request script :-
setTimeout(function(){}, [50000]);
I reduced time duration to 30 seconds:
setTimeout(function(){}, [20000]);
After that I stopped getting this error.
I solved this problem with disconnection my vpn. you should check if there is vpn connected.
What helped for me was replacing 'localhost' in the url to http://127.0.0.1 or whatever other address your local machine has assigned localhost to.
Socket hang up error could be due to the wrong URL of the API you are trying to access in the postman. please check the URL once carefully.
It's possible there are 2 things, happening at the same time.
The url contains a port which is not commonly used AND
you are using a VPN or proxy that does not support that port.
I had this problem. My server port was 45860 and I was using pSiphon anti-filter VPN. In that condition my Postman reported "connection hang-up" only when server's reply was an error with status codes bigger than 0. (It was fine when some text was returning from server with no error code.)
When I changed my web service port to 8080 on my server, WOW, it worked! even though pSiphon VPN was connected.
Following on Abhay's answer: double check the scheme. A server that is secured may disconnect if you call an https endpoint with http.
This happened to me while debugging an ASP.NET Core API running on localhost using the local cert. Took me a while to figure out since it was inside a Postman environment and also it was a Monday.
In my case, adding in the header the "Content-length" parameter did the job.
My environment is
Mac:
[Terminal command: sw_vers]
ProductName: macOS
ProductVersion: 12.0.1. (Monterey)
BuildVersion: 21A559
mysql:
[Terminal command: mysql --version]
Ver 8.0.27 for macos11.6 on x86_64 (Homebrew)
Apache:
[Terminal command: httpd -v]
Server version: Apache/2.4.48 (Unix)
Server built: Oct 1 2021 20:08:18.
*Laravel
[Terminal command: php artisan --version]
Laravel Framework 8.76.2
Postman
Version 9.1.5 (9.1.5)
socket hang up error can also occur due to backend API handling logic.
For example - I was trying to create an Nginx config file and restart the service by using the incoming API request body. This resulted in temporary disconnection of the Nginx service while handling the API request and resulted in socket hang up.
If you have tried all the steps mentioned in other comments, and still face the issue. I suggest you check the API handler code thoroughly.
I handled the above-mentioned example by calling the Nginx reset method with delay and a separate API to check the status of the prev reset request.
For me it was giving Socket Hung Up error only while running Collection Runner not with single request.
Adding a small delay (100-300ms) in the collection Runner solved issue for me.
In my case, I had to provide --ssl-client-key and --ssl-client-cert files to overcome these errors.
Great error, it is so general that for everyone something different helps.
In my case I was not able to fix it and what is really funny is fact that I am expecting to get multipart file on one endpoint. When I prepare request in postman I get "Error: socket hang up". If I change for other endpoint(even not existing) is exactly that same error. But when I call any endpoint without body that request works and after that all subsequent attempts works perfectly.
In my case this is purely postman issue. Any request using curl is never giving that error.
For me the issue was related to the mismatch of the http versions on the client and server.
Client was assuming http v2 while server (spring boot/ tomcat) in the case was http v1
When on the server I configured server to v2, the issue got resolved in a go.
In spring boot you can configure the http v2 as below:-
server.http2.enabled=true
Note - Also the scenario was related to using client auth mechanism (i.e. MTLS)
Without client auth/ MTLS it worked without issues but for client auth the version setting in spring boot was the important rescue point
"socket hang up" is proxy related issue. when we run same collection with the help of newman on jenkins then all test are passed.
change the proxy setting
https://docs.cloudfoundry.org/cf-cli/http-proxy.html
I had the same issue: "Error: socket hang up" when sending a request to store a file and backend logs mentioned a timeout as you described. In my case I was using mongoDB and the real problem was my collection’s array capacity was full. When I cleared the documents in that collection the error was dismissed. Hope this will help someone who faces a similar scenario.
"Socket Hung Up" can be on-premise issue some time's, because, of bottle neck in %temp% folder, try to free up the "temp" folder and give a try
I fixed this issue by disabling Postman token header. Screenshot:
I face the same issue in when calling a SOAP API with POSTMAN
by adding the following data in the header my issue was fixed
Key:Content-Length
Value:<calculated when request is sent>
In my case, I was incorrectly using a port reserved for https version of my api.
For example, I was supposed to use https://localhost:6211, but I was using http://localhost:6211.
It is port related error. I was trying to hit the API with an invalid port.
if it helps to anybody... In my case, i just forgot to use json parser (const jsonParser = express.json();) to have access to json type of objects sending to the server from the client. Be careful, don't waste your time =)
This happened to me while I was learning ASP.NET Web API.
In my case it was because the SSL certificate verification.
I was using VS Code so I oversee about SSL certificate verification and it came with https protocol.
I solved this with testing my endpoints with http protocol.
Another approach can be just disabling the SSL certificate Verification on Postman Settings.
This error was coming for me since the request url is not correct --> here you can see my url does not contains : after http
The url I was using was : http//locahost:9090/someApi
Solution
adding a colon new url is http://localhost:9090/someApi
the socket error was not coming
This is just my case may be your case is totally different as mentioned in the other answers :)

Cannot get response from github server

I'm using POCO library to establish communication between my app and github in order to use its API, and unfortunately after sending (successfully) very basic request I'm not getting any response:
URI uri("https://api.github.com/zen");
std::string path(uri.getPathAndQuery());
HTTPClientSession client(uri.getHost(),uri.getPort());
HTTPRequest req(HTTPRequest::HTTP_GET, path, HTTPMessage::HTTP_1_1);
client.sendRequest(req);
HTTPResponse res;
client.receiveResponse(res);//this throws error "Poco::Net::NoMessageException"
I've checked this URI and after pasting it into browser I'm getting correct response, that is, random "wisdom" from github server.
Does anyone has any idea how to fix my code so it actually gets the response?
You are trying to connect to a secure server using insecure protocol. Use HTTPSClientSession.

Client identifier in jboss httpinvoker (auditing)

I am using httpinvoker in JBoss 4.0.4 (little old) for EJB invocations.
Since there are so many clients that make calls to my server, I want to identify the clients for each call in server.
Is there a way to do this with JBoss httpinvoker?
I could imagine adding a header to identify my client in each HTTP request, but cannot find a way to add a header in httpinvoker.
Auditing builds on a name, and thus on an authentication scheme somehow.
Therefore I suggest using the standard client authentication infrastructure to solve your problem. This works for RMI as well (it's not bound to HTTP), and the user ID is even passed down into your EJBs.
Server
Put the EJB in a security-domain (ejb.jar: META-INF/jboss.xml)
You could use the application-policy other which just the UsersRolesLoginModule (conf/login-config.xml); this is the default policy, it's already configured.
Add users.properties and roles.properties to your ejb.jar file (top level package): These are used by the UsersRolesLoginModule
For each user, add his name and a (dummy) password to users.properties
Client
Create a callback class which implements a javax.security.auth.callback.CallbackHandler: This callback is used, when the authentication needs the user and the password.
Create a javax.security.auth.login.LoginContext; pass the callback handler as the 2nd argument; call login() on the instance of the LoginContext
Connect normally to the EJB server using an InitialContext
Add -Djava.security.auth.login.config=.../jboss-4/client/auth.conf when you start the client
This way a user ID is passed from the client to the EJB (as part of the standard authentication process). Now, in the EJB methods, you can get the user ID by calling getCallerPrincipal() on the SessionContext instance. I have tested this against JBoss 4.2.3
Additional information: JBoss client authentication
Addendum 1:
Using RMI or HTTP, the password is not transported in a secure way. In this case just use a dummy password, this is OK for auditing.
On the other hand, if you use RMI over SSL or HttpInvoker over HTTPS, you could change to a real and secure authentication quickly.
Addendum 2:
I am not sure, if it works without defining roles. Possibly you have to
Add a line in roles.properties for each user: Add a connect role, for example
Add role definitions in ejb-jar.xml as well: security-role-ref for each EJB, and security-role and method-permission in the assembly-descriptor
Update
As there is already a login module, there might be another possibility:
If you have the source code of the login module, you could possibly use another TextCallback to get additional information from the client (in your case a user ID). The information could be used to create a custom Principal. Within the EJB, the result of getCallerPrincipal() could be cast to the custom principal.

Perl SOAP::WSDL accessing HTTPS Unathorized error

I'm trying to generate a Perl library to connect to a WebService. This webservice is in an HTTPS server and my user has access to it.
I've executed wsdl2perl.pl several times, with different options, and it always fails with the message: Unauthorized at /usr/lib/perl5/site_perl/5.8.8/SOAP/WSDL/Expat/Base.pm line 73.
The thing is, when I don't give my user/pass as arguments, it doesn't even asks for them.
I've read [SOAP::WSDL::Manual::Cookbook] (http://search.cpan.org/~mkutter/SOAP-WSDL-2.00.10/lib/SOAP/WSDL/Manual/Cookbook.pod) and done what it says about HTTPS: Crypt::SSLeay is instaleld, and both SOAP::WSDL::Transport::HTTP and SOAP::Transport::HTTP are modified.
Can you give any hint about what may be going wrong?
Can you freely access the WSDL file from your web browser?
Can someone else in your network access it without any problems?
Maybe the web server hosting the WSDL file requires Basic or some other kind of Authentication...
If not necessary ,I don't recommend you to use perl as a web service client .As you know ,perl is a open-source language,although it do support soap protocol,but its support do not seem very standard.At first,its document is not very clear.And also ,its support sometimes is limited.At last,bug always exists here and there.
So ,if you have to use wsdl2perl,you can use komodo to step into the code to find out what happened.This is just what I used to do when using perl as a web service client.You know ,in the back of https is SSL,so ,if your SSL is based on certificate-authorized,you have to set up your cert path and the list of trusted server cert.You'd better use linux-based firefox to have a test.As I know ,you can set up firefox's cert path and firefox's trusted cert list.If firefox can communicated with your web service server succefully,then,it's time to debug your perl client.
To debug situations with Perl and SOAP, interpose a web proxy so you can see exactly what data is being passed and what response comes back from the server. You were getting a 401 Not authorized, I expect, but there may be more detail in the server response.
Both Fiddler http://docs.telerik.com/fiddler and Charles proxy https://www.charlesproxy.com/ can do this.
The error message you quote seems to be from this line :
die $response->message() if $response->code() ne '200';
and in HTTP world, Unauthorized is clearly error code 401, which means your website asks for a username and password (most probably, some website may "hijack" this error code to cater for other conditions like a filter on the source IP).
Do you have them?
If so, you can
after wdsl2perl has run, find in the created files where set_proxy() is called and change the URL in there to include the username and password like that : ...->set_proxy('http://USERNAME:PASSWORD#www.example.com/...')
or your in code, after instantiating the SOAP::WSDL object, call service(SERVICENAME) on it (for each service you have defined in your WSDL file), which gives you a new object, on which you call transport() to access the underlying transport object on which you can call proxy() with the URL as formatted above (yes it is proxy() here and set_proxy() above); or you call credentials() instead of proxy() and you pass 4 strings:
'HOSTNAME:PORT'
the realm, as given by the webserver but I think you can put anything
the username
the password
