Firefox telnet not working

I am using Firefox to access eve-ng server.

Basically, each node is exposed as a telnet link such as the following: telnet://192.168.1.168:36323
I have made sure that I have enabled the following in Firefox and restarted Firefox: network.protocol-handler.expose.telnet and set the value to false

When clicking on the link that is a telnet link I get to select the system handler option, which when I select just launches Konsole but no telnet to the endpoint.

After searching I found the following script that I have now located in /usr/bin directory and from Firefox I point to this script but nothing happens: The script is as follows:


#!/bin/sh 
#address=`echo ${*##telnet://} | sed 's/:/ /g'` 

address=`echo $1 | cut -d : -f 2 | sed 's;/;;g'` 
port=`echo $1 | cut -d : -f 3` 
exec /usr/bin/konsole -e telnet $address $port 
#exec /usr/bin/xterm -e telnet $address $port

The above script works when I execute from the CLI such as following:

fftelnet telent://192.168.1.168:58129

But it does not work when I select this from Firefox.

I have attached the image of what happens in firefox: When I select fftelnet and press OK nothing happens

Please help.

Browsers and telnet don't go very well together these days. Handshakes aren't fulfilled and a number of things have become non-compatible, from the browser's side. I am not sure why you need this, but I am certain it will never work properly. Plus, through a browser you have no keyboard to type inside a telnet session.

Hi, this is not running telnet inside the browser, this is when clicking a link which is of type telnet it will launch the system terminal and start the telnet session. Hope that explains it thanks

Insert into your script a command that echoes `$1`, `$address` and `$port` into some file in `/tmp`. You can check this way if correct parameter is passed to your script.

Hi there, I checked the output of the script and provides the correct parameters.

So maybe try replacing `telnet` with a full path to telnet binary in the command that is calling Konsole... I have no other idea... Is there maybe any error message in the Konsole window that is opened?

I used this:

#!/bin/bash
#
# Linux shell script called by Firefox in response to
# telnet:// URLs for the NNMi telnet menu.
#
address=`echo $1 | cut -d : -f 2 | sed 's;/;;g'`
port=`echo $1 | cut -d : -f 3`
exec /usr/bin/gnome-terminal -- telnet $address $port

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
