How to trojan a Telnet Client


I want to log the user name and password passed through the default telnet client on Fedora (7 to 11) system.

I have thought of something like this:

(Download Telent client src)->(modify src)->(compile and install)

but i am not sure...
Can someone help me out with this?

Hi,

I have to assume you have good intentions, but I doubt this thread will stay open long. This smells too much like hacking.....

I suspected such questions. But given that i have admin acess (that i can install the program) , my intentions are of little importance.

Hi,

Your intentions, be it good or bad, are not the issue here. LQ has very strict policies when it comes to this "grey area" and most (senior) members will not answer this one.

I don't think anyone has reported it yet, but I do believe that once a moderator stumbles upon this thread it will probably be closed.

I will rephrase that question:

What is the standard procedure to obtain source code of common programs(eg Telnet Client), modify it(eg.Change the prompt) , compile and install it.

I think this is less gray or should i start a seperate thread?

thanks

Hi,

The source code of most of the linux programs are freely available and most of those have licenses that allow you to modify them....

Telnet is part of the GNU Inetutils package. All the rest is up to you.

I don't think your rephrasing will help. It is the same content in a different package

Not here they're not. We don't provide hacking/cracking help for anyone. And think about what you're saying....just because you SAY you have admin access, and that your intentions are good, how do we know that?

If you have admin access, then you've also got access to everyone's shell history, and can see all the commands they've entered/run. You've also got access to all the system logs, etc., so not sure what you could possibly gain by this. And if you want to modify the source, go for it. Download it, and make the changes. If you don't know HOW to make the changes, then either hire someone to do it for you, or learn how to program, and do it yourself. Again, not sure how anyone here can 'help' with this.

So you knowingly post anyway. What should we make of that?..

What is important are the environment and the reasons for wanting to do this. If this is a machine owned by or connected to a corporate or institutional network then you should be aware your actions may subject the company or institution to litigation if a legitimate user finds out you have violated Privacy Laws: please consult your legal department if unsure before continuing. If this is your own machine (meaning you pay for it, its network and its network access) then maybe you could ease things by explaining why you think you need to do this. If you can not or will not (and I request you indicate it) then this thread should be closed. Please understand that LQ does not want to be associated with this type of questions.

Get telnet-0.17-43.fc11.src.rpm and head over to http://fedoraproject.org/wiki/Packag...ngPackageHowTo.


I request other LQ members do not respond until the OP has.

The procedure would be to obtain the source code, modify it, compile it, and install it.
