ext_file_userip_acl(8)

NAME
ext_file_userip_acl - Restrict users to certain IP addresses, using a text file backend.

Version 1.0

SYNOPSIS
ext_file_userip_acl [-dh] [-f file name ]

DESCRIPTION
ext_file_userip_acl is an installed binary. An external helper for the Squid external acl scheme.

It works by reading a pair composed by an IP address and an username on STDIN and matching it against a configuration file.

OPTIONS

-d  Write debug info to stderr.

-f file
    Configuration file to load.

-h  Display the binary help and command line syntax info using stderr.

CONFIGURATION

The squid.conf configuration for the external ACL should be:
    external_acl_type type-name %SRC %LOGIN /path/to/ext_file_userip_acl -f /path/to/config.file

If the helper program finds a matching username/ip in the configuration file, it returns OK , otherwise it returns ERR .

The configuration file format is as follows:
    ip_addr[/netmask]    username|@group|ALL|NONE

Where ip_addr is a dotted quad format IP address, the netmask must be in dotted quad format too.

When the second parameter is prefixed with an @ , the program will lookup the /etc/group file entry for the specified username.

There are other two directives, ALL and NONE , which mean "any user on this IP address may authenticate" or "no user on this IP address may authenticate".
