SQUID: How to disable authentication?

Question

I have a working Squid with authentication. How do I temporarily disable authentication? Can I just comment out the following lines below from squid.conf:

acl ncsa_u

Answer 1

Try with:

Comment:

#acl ncsa_users proxy_auth REQUIRED
#auth_param basic program /usr/lib/squid3/ncsa_auth /etc/squid3/passwd auth_param basic
#children 5 auth_param basic realm Squid proxy-caching web server auth_param basic  
#credentialstt1 2 hours auth_param basic casesensitive off

And modify:

http_access deny all

to:

http_access allow all 

Answer 2

#file /etc/squid/squid.conf

#squid version 3.5.27

#operating system ubuntu 18.4

#last update 20201221

#cloud aws ec2

#aws ec2 security group all traffic open inbound and outbound

http_access allow all

http_port 3128

acl SSL_ports port 443

acl Safe_ports port 80 # http

acl Safe_ports port 21 # ftp

acl Safe_ports port 443 # https

acl Safe_ports port 70 # gopher

acl Safe_ports port 210 # wais

acl Safe_ports port 1025-65535 # unregistered ports

acl Safe_ports port 280 # http-mgmt

acl Safe_ports port 488 # gss-http

acl Safe_ports port 591 # filemaker

acl Safe_ports port 777 # multiling http

acl CONNECT method CONNECT

http_access allow localhost manager

http_access allow localhost

coredump_dir /var/spool/squid

refresh_pattern ^ftp: 1440 20% 10080

refresh_pattern ^gopher: 1440 0% 1440

refresh_pattern -i (/cgi-bin/|?) 0 0% 0

refresh_pattern (Release|Packages(.gz)*)$ 0 20% 2880

refresh_pattern . 0 20% 4320

Answer 3

I solved it.. I just commented out

#auth_param basic program /usr/lib/squid3/ncsa_auth /etc/squid3/passwd

and then commented out acl ncsa_users proxy_auth REQUIRED

#acl ncsa_users proxy_auth REQUIRED

acl ncsa_users dst 10.244.0.0/16 all

Then restarted squid

I hope someone may find this useful.

Answer 4

This worked for me, only defined IP allowed to use squid
