We are trying to setup a chain of proxy server in our development system. We wanted to connect to a service through these proxies. The reason why we thought about proxy chaining is that there is no connectivity to the service from all the systems. So we thought we will run a proxy on one system, which will connect to a proxy on another system and so on.
Client ---> A (Proxy)--->B(proxy)---->Final destination
Could you please suggest some tools to achieve this? The service that we have is a SOAP based secured web service.
There is an open source application called ProxyChain for this, here is readme file for this project:
http://proxychains.sourceforge.net/howto.html
You can install as more as proxy chains you want using this open source software, you can configure it per your requirements. Also you can somehow use some port-forwarding. What is the client for SOAP requests? Is it a web or desktop application?

I am trying to establish a connection with quickfix/n but I am behind the company firewall. So I need to connect over a proxy to the acceptor.
According to the documentation of quickfix/j it is possible via JAVA, however in the documentation of quickfix/n there is no information about possibility of connecting to the acceptor over a proxy via C#.
Is it possible at all to do that from C# with quickfix/n ?
In JAVA this can be done via configuration file, e.g.:
ProxyType=http
ProxyVersion=1.1
ProxyHost=XXX.XXX.XXX.XXX
ProxyPort=YYYY
QuickFix/n v.1.7.0 does not support proxy at all.
QuickFix/n v.1.10.0 does support proxy (automatic via. WebRequest.GetSystemWebProxy()), however it does not support bypassing of the proxy details (user name and password).
I have created my own fork from v1.7.0 that supports user defined proxy (not WebRequest.GetSystemWebProxy) + credentials. This can be found here: https://github.com/mcjacek/quickfixn
ProxyHost=proxy.intranet.yourproxy.com
ProxyPort=8080
ProxyUserName=UserName
ProxyUserNamePassword=Password
I will soon refactor and create PR to merge it to master.
I'm trying to see if it is possible to set HTTP proxy configuration programmatically from my C++/WinRT code. I found that one can get the current proxy configuration with NetworkInformation.GetProxyConfigurationAsync from UWP. But is it possible to change it?
My goal is to find a proxy server on the local network and set it up for Edge (or any other browser in the system) as the HTTP proxy. So, that afterward, for whoever is using a browser on that system, all requests would go through the proxy server.
I don't seek to use UWP or any application model in particular. Any way of achieving my goal (that described above) from C++ code would work.
I can not connect to Google Services from client application if it is trying to communicate with oauth2.googleapis.com (which is probably blocked in my corporate network - I dont know how to test it for sure).
I tried BigQuery with JDBC driver in Dbeaver. With basic settings.
User-based login does this:
It generates link for OAUTH. I open the browser and login with the right google account. Then I insert generated code into the Dbeaver and I recieve that AUTH has failed.
Service-based login does this:
It does not want me to visit any webpage. It just tells me:
[Simba][BigQueryJDBCDriver](100004) HttpTransport IO error : oauth2.googleapis.com.
I also tried to use ODBC, where PROXY can be filled in. But no luck.
When I take a look into 'Proxy Options' the proxy port is always rewritten by proxy host. Weird.
This is what happens when i click on 'catalog' or 'dataset' drop-down field. I cant do any further steps.
BUT!
When I set my HTTP PROXY in GCLOUD CLI APP then communication works. And I can call BQ from it.
Does it mean that GCLOUD communicates through HTTP Proxy and DBeaver or ODBC does not? Or does it mean that GCLOUD does not need oauth2.googleapis.com but ODBC and JDBC do and it is blacklisted? I am confused.
We need to migrate from our internal environment to GCP. We would love to use various applications. I would ask for whitelisting oauth2.googleapis.com but i am not sure this is the only problem as GCLOUD app works without any flaws.
I am not-experienced with networking so i am more than happy to update / correct this question or add any info (if you need) to help me understand this issue. Thank you
According to your description, your corporate network is using a Proxy to reach out Internet, this is the reason why gcloud is capable to reach out BigQuery service when Proxy settings are configured in your system; through Cloud SDK Proxy settings or HTTP PROXY environment variable.
You require to setup the proxy settings within the JDBC connection string as described in Simba JDBC driver documentation, e.g.:
jdbc:bigquery:DataSetId=MyDataSetId;ProjectId=MyProjectId;OAuthType=1;ProxyHost=MyProxyHost;ProxyPort=MyProxyPort;ProxyUID=MyProxyUsername;ProxyPWD=MyProxyPassword
This connection string will indicate the Proxy settings to Simba JDBC driver.
I have written a web application that is, typically, installed internally by customers (based on IIS/MSSQL server).
When a customer wants to provide external access to the application, we offer the following supported scenarios:
Publish the application in their DMZ (pretty standard deployment).
Use our own platform where we host the application in our own cloud infrastructure for them.
However, because I have more and more customers who misunderstand the requirements for publishing an internal application, I would like to add a "one click" way of providing that service.
My idea is to have a reverse proxy installed on the customer's web server that will connect to a cloud server we control. When the application starts, it will connect to our server, authenticate and maintain the connection. When a user wants to use the application, she will use an URL that directs it to our server (say https://myapp.mycompany.org/CustomerID or https://CustomerID.myapp.mycompany.org). The server will then lookup the list of connections from reverse proxy to find the one matching the customer ID and, if found, use that connection to relay the end user connection.
In essence, that is the same thing as what Azure Application proxy or TeamViewer do, only without the need for using Azure AD or TeamViewer.
Is there an existing framework I can use for building such a service ? I know I can write it on my own but that is quite a large development.
I´m running Microstrategy Desktop v. 10.5.0 on Windows 10 and I´m trying to build a few maps. I´m behind a HTTP proxy in the format
http_proxy=http://<user>:<password>#proxy.mycorp.com:8080
https_proxy=http://<user>:<password>#proxy.mycorp.com:8080
and every time I try to start a map I get the message
Unable to download the ESRI map. No Internet connection. You can configure an Internet proxy through you computer´s Settings.
The internet works for all other programs with the same proxy and the ESRI CDN links also work directly on the browser behind the proxy. If I connect to a network outside my work connection and disable the proxy the maps work. Is there a way to make Microstrategy Desktop work behind a proxy?
Can you please look into the following link, You have to check with your network admins and request them to unblock some websites and ports.
https://community.microstrategy.com/t5/Clients-Interfaces/Sporadic-issues-with-ESRI-maps-in-Desktop-10-with-proxy-setting/td-p/248444
We faced the same issue, and we requested our network admin team to do the following :
For simpicity, you could open below configuration in the firewall:
Ports 443 , 80 and 6080
*.arcgis.com, *.esri.com and *.arcgisonline.com
Starting with MicroStrategy Analytics Enterprise 9.4.1 Hotfix 6 and in MicroStrategy 10.X, users are able to configure MicroStrategy Web to send HTTP request to ESRI via internal proxy servers. The following provides the details
Un-authenticated proxy :
If the proxy server does not require authentication, user can go to Web Administration security page and configure the following settigs
Go to Web Administration --> Security Page.
Check "Enable HTTP proxy server"
Fill out the Server address and Server port
enter image description here
Authenticated proxy server
It the proxy server requires authentication , User will need to add in the esriconfig.xml file located under plugins\ConnectorForESRIMap\WEB-INF\xml\config (see sample below).
Note: Restart the web server after this change
