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
-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".
