I want to run may instances of squid proxies. But I am only able to connect with them when squid is started with sudo. In the squid config I have:

access_log none
cache_store_log none
cache_log none

$ squid -n squida -f /tmp/squid_80fm8klt.conf                                                                                                              
$ curl --proxy http://localhost:3129  https://httpbin.org/ip
