How to make a Permanent Backdoor in Linux Servers after compromising the target ? Help and thanks advanced for you help ...
-
netcat...

Have you ever heard about rootkits?

Please, do some more searching before posting a generalized question like that. GOOGLE will be more than happy to give you a ton of results for linux backdoor; 2, 920, 000 results.
Once you have the idea down, and have tried getting it to work on your VM or test comp, then feel free to ask us specific questions about the problems your having. Hacker's (or just computer geeks like me) value independence, so we help those who have already helped themselves.
Hopefully you learn something and find what you need, gl mate.

Yeah thanks ... :)

It can't be really permanent, but you have few options..
1. Inserting into kernel (recompiling kernel or LKM)
2. Adding to startup
If you use the 1st one, it's more difficult to get detected if you recompile the kernel (unless it's poorly coded, then it'll just oops the kernel XD)
Adding stuff to startup is not a clever idea, because it's like.. really visible XD
If you're interested in doing kernel level stuff you can ask me questions, I've messed with that stuff a bit ;)
