As per writeups, i am trying to change the proxy and visit 127.0.0.1 but nothing happens. I am currently using foxyproxy to quickly add proxies. I named a new proxy as squid and added 10.10.10.21 as ip address and 3128 as port to use the squid proxy avilable on JOKER. I did this manually from network prefrences in my firefox browser on kali linux. Nothing happens.
Also trying to scan the udp ports on this machine takes forever.
