Hi Mohtashims,

I'm now sitting on my notebook and I checked the two different Debug-Outputs of the 2 ssh connections. I clearly see differences.

I assume, you have - as I suggested - to debug the server side. But from the client side, there are visible differences, which shed a little light on the situation.

General Hints

I'm watching you and your questions quite a while. Your technical knowledge is quite good. You have scripting skills. You know how to use the commands and build programs upon that. That's very good.

What I see too, is that you are quickly asking questions if you stumble upon errors like here. So I think a further good skill, which will bring you forward in your overall competence would be problem investigation and problem solving capability.

What do you need for that?
  • Patience and willingness to deeply and carefully investigate a problem. Take your time, read debug output very carefully.
  • Try to understand what's happening! Step by step.
  • Think about it! What can be wrong? Where can be an error?
  • Think about how to get more information in the process! Where to get more information in the process?
  • Isolate more and more exactly the spot of the error
  • Debug output your variables
  • Make small test programs

    If you do not understand why the whole program reacts like it does, take small bits out of it and make a small testing program and take the problematic data into that.
  • Be prepared for own blind spots.

    Program errors you do not recognize even if they are directly in front of you, even if you'd seen them a dozen of times.(I had two spelling errors in your name in this post even if I read a hundred times in this forum so far.) Maybe Programming language behaviour that is not like you always believed it to be.
  • From time to time a break helps a lot


Apply that on the current problem and you will get closer to the cause.

So my question to you is here: What are the differences between the two client connection session debug logs?

NAME
Net::XMPP::Debug - XMPP Debug Module SYNOPSIS
Net::XMPP::Debug is a module that provides a developer easy access to logging debug information. DESCRIPTION
Debug is a helper module for the Net::XMPP modules. It provides the Net::XMPP modules with an object to control where, how, and what is logged. Basic Functions $Debug = new Net::XMPP::Debug(); $Debug->Init(level=>2, file=>"stdout", header=>"MyScript"); $Debug->Log0("Connection established"); METHODS
Basic Functions new(hash) - creates the Debug object. The hash argument is passed to the Init function. See that function description below for the valid settings. Init(level=>integer, - initializes the debug object. The level file=>string, determines the maximum level of debug header=>string, messages to log: setdefault=>0|1, 0 - Base level Output (default) usedefault=>0|1, 1 - High level API calls time=>0|1) 2 - Low level API calls ... N - Whatever you want.... The file determines where the debug log goes. You can either specify a path to a file, or "stdout" (the default). "stdout" tells Debug to send all of the debug info sent to this object to go to stdout. header is a string that will preappended to the beginning of all log entries. This makes it easier to see what generated the log entry (default is "Debug"). setdefault saves the current filehandle and makes it available for other Debug objects to use. To use the default set usedefault to 1. The time parameter specifies whether or not to add a timestamp to the beginning of each logged line. LogN(array) - Logs the elements of the array at the corresponding debug level N. If you pass in a reference to an array or hash then they are printed in a readable way. (ie... Log0, Log2, Log100, etc...) EXAMPLE
$Debug = new Net::XMPP:Debug(level=>2, header=>"Example"); $Debug->Log0("test"); $Debug->Log2("level 2 test"); $hash{a} = "atest"; $hash{b} = "btest"; $Debug->Log1("hashtest",\%hash); You would get the following log: Example: test Example: level 2 test Example: hashtest { a=>"atest" b=>"btest" } If you had set the level to 1 instead of 2 you would get: Example: test Example: hashtest { a=>"atest" b=>"btest" } AUTHOR
