ext_file_userip_acl(8) System Manager's Manual 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

Write debug info to stderr.
Configuration file to load.
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".
