Basic (literarily) Equipment

Hey there,

I would like to ask if there are any good books which you guys can recommend (understanding networks, better overview over kali, metasploit...).

I looked a lot at amazon, but I found a lot of crap.

Books with just an oneliner to every tool.

Wow very helpful :D

I am also looking for an antenna for WiFi hacking.

I heard a lot about alfa.

Something like that?

If there's any basic equipment it would be great if you guys just hit me in the comments below ;)

Cheers
