Native Messaging Problem between linux app and wine native app (piping linux app to wine app)

[muhammedemintombak]

Hello Guys,
I am using Debian 10 Buster and wine 6.0 rc1.
My problem is native messaging between linux app to wine app.
The wine app is e-signature application (arksigner windows version).
This app have also linux version, but My company's firewall denies the app. So, the linux app does NOT working.
I have installed the wine app and windows versions of web browsers on wine 6.0 rc1, and I am using the wine application this way. But, it is the problem, because I have to install windows versions of web browsers on wine!

this wine app talks web browsers via a web extension that is for web browsers. The web extension sends native messages to the wine app via Native Messaging Hostmodule.
My problem is starting here.

I have installed the web extension to linux version of web browsers and written bash script to call the wine app and called the bash script in JSON file that is used by Native Messaging Host module. So I have been able to call the wine app with this way. BUT, when i call the wine app, the wine app closes immediately. So, the wine app can not receive any messages and closes.
I have looked logs of the wine app and seen that is "taken close signal and program closed". I have searched and NOT found anything.
I have found only that this is Piping problem between wine and linux, and Winelib is necessay for solution

How must I do? How can I solve this problem?
Could anyone help?

Hi, it is not clear from your description how company firewall can deny linux app but allow windows app - firewall is operating in terms of network protocols, but these apps should behave similarly in terms of network traffic. Are you saying that your company disallows downloading linux version? then as I assume you have admin rights on your PC - you can download the app yourself and install it via different network connection.
I am trying to explain that using the linux browser / linux extension route is easier to debug/fix rather than trying to try the mix of windows browsers in wine with linux externsion app

Hi, it is not clear from your description how company firewall can deny linux app but allow windows app -

the linux application can not use native messaging. So, web extensions do NOT work with linux app. The linux app uses web sockets and socket1v2 and listens port 16357 to talk to server of linux app. Our company's firewall blocks everything. We have to use certificate and proxy server to connect internet. Our company's firewall blocks communication of linux app and its server.

As the windows app talks to web browser via web extension, firewall does not see and does not deny it.
my bash script is

Code: Select all

#!/bin/sh



set -e

EBYS_DIZINI="$HOME/.ebys32"
if [ -d "$EBYS_DIZINI" ]; then
    
    env WINEPREFIX="$EBYS_DIZINI" /opt/wine-mtombak/bin/wine c:\\ProgramData\\Ark\\ArkSigner\\ArkSignerBEs.exe

fi


echo "Muhammed Emin TOMBAK"
sleep 500
exit 0

# vim: ts=2 sw=2

I can call the windows app with this, But the app closes immediately. The app does NOT talk to web extension as i have written in my topic.

I have to use linux versions of browsers and their extensions, and the wine app due to blocking of our company's firewall.
the web extensions are the same on linux and windows versions of web browsers

I doubt you can use wine app inside web extensions API, as it was designed to prevent external applications launch and use only html/javascript

Web extensions use Native Messaging Host module. So, they need JSON file only. I have edited JSON file as that :

Code: Select all

{
   "name": "com.ark.pw.websigner",
   "description": "ARK Teknoloji | ArkSigner Firefox Extension",
   "path": "/home/HSSGM/mtombak/.mozilla/native-messaging-hosts/ArkSignerBEsCalistir",
   "type": "stdio",
   "allowed_extensions": [
     "[email protected]"
   ]
}

ArkSignerBEsCalistir is my bash script.

I put this json file on $HOME/.mozilla/native-messaging-hosts.
Web extension send message to bash script, but the script can not send anything to wine app.
How can I use web extensions API to call the wine app?

but having looked at arksigner architecture, there is arksignerd daemon running locally, and web extension, assuming talking to it. Have you tried running native linux arksigner and checking arksignerd logs (apparently in /logs/arksigner-service.log) to check what is causing its inability to connect? it might be that arsignerd is not configured to use the proxy that your company is requiring, in that case it is required to pass it as a configuration settings (either via HTTP_PROXY environment variable or some other way).

[muhammedemintombak]

I have spoken with Arksigner Company. they told me that the linux app can not be configured for proxy. It connects internet directly.
I have also tried the app with proxychains and it is fail
I have looked the log file. that is:

The log files do not say anything

The app has located in /usr/bin/arksigner folder
it has two files only that are arksigner-service and arksigner-universal.
In this folder, there are not anything about web extensions.

[savelov]

you might need to try transaprent proxy setup via NAT, similar to below documentation, however need to ensure that both http(80) and https(443) traffic is forwarded - acceptance criteria would be that web borwser works without its own proxy configuration.

https://tldp.org/HOWTO/TransparentProxy-6.html#ss6.1

I still think that linux driver should be much easier to configure (even with these proxy settings) rather than fighting with wine browser extensions.

@muhammedemintombak you can contact me and I think I can help you sort it out

[muhammedemintombak]

I have added you on skype. thank you very much

[savelov]

this is resolved by using native arksigner application and excluding address local.pwsigner.ark-teknoloji.com from going to proxy

[muhammedemintombak]

thank @savelov to his helps.
we use linux native application. we have added local broadcast address (local.pwsigner.ark-teknoloji.com) to hosts file and exclude this address in the cntlm proxy settings.
We have not used wine application.
@savelov has helped me very much. I thank him very much
