Hello zawar rawaz, & welcome to LQ.

Arp Spoofing is a hacking technique usually not the first thing I'd encourage a linux newbie to get up to. Have you a download link for the arpspoof program you are using?

In practise there are mitigations against arp spoofing in place. There is even a site offering $500 to anyone who can successfully hack it. When last I was there, it hadn't been claimed, although the offer might still be valid.http://cr.yp.to

I am learning Networking in kali linux and I am using ARP spoof already installed there and it worked recently I don't know what was the problem and I use ip of my second windows VM. I didn't understand $500 reward for which task and the site of http://cr.yp.to is also complex I didn't understand where to go.

I think the offer was linked to his qmail stuff. The guy's mad, and may well be dead for all I know. I really tried with qmail & failed back then, & resorted to postfix. Later, I found http://lifewithqmail.org. That seemed to make a secure mail server possible. But it was a different time with different hacking techniques.

As for learning Networking, there's the CCNA. The syllabus may be online. I wouldn't recommend the exams.

alright thank you for sharing your experience I will learn more but there is so much over knowledgeable information out there and I don't want to waste time

Hi, are there more websites with rewards for hacking them?

I believe there's great kudos to be had from hacking anything Russian or North Korean atm. Mind you, most north Korean hackers live abroad. There might be a prize for the site http://cr.yp.to but personally, I think the tilde is worth more than the prize for hacking it.

The guy wrote a replacement for inetd, bind, and that some web server thing, I think. If he did, they'd all be in use there.
