Sto eseguendo nmap tramite proxychain usando questo comando:
proxychains nmap -v scanme.namp.org
Questo ha prodotto un errore:

|DNS-response| scanme.nmap.org is 45.33.32.156
45.33.32.156/0 looks like an IPv6 target specification -- you have to use the -6 option.
Read data files from: /usr/bin/../share/nmap
WARNING: No targets were specified, so 0 hosts scanned.
Nmap done: 0 IP addresses (0 hosts up) scanned in 0.94 seconds
Poi sono andato a questa domanda ( qui ) e ho provato questo:
to the solution was, that I disabled the DNS through socks:
in /etc/proxychains.conf file, just add a # before the line "proxy_dns"
Ma quando ho eseguito nmap tramite proxychains, la scansione di nmap era in esecuzione, ma il proxy proxychains non funzionava, il che mi ha dato il seguente output dettagliato:

Da questo possiamo vedere che la nmap funziona bene, ma la mia domanda è: perché nmap ha inizio non appena il comando è stato eseguito senza tunneling attraverso i proxy ?, ma se ho eseguito un comando come questo:
proxychains firefox www.google.com
Ho ottenuto il seguente output dettagliato che mostra il tunneling dei proxy.
root@kali:~# proxychains firefox www.duckduckgo.com
