.PP
Version 1.0
.
.SH SYNOPSIS
.if !'po4a'hide' .B ext_file_userip_acl
.if !'po4a'hide' .B [\-dh] [\-f 
file name
.if !'po4a'hide' .B ]
.
.SH DESCRIPTION
.B ext_file_userip_acl
is an installed binary. An external helper for the Squid external acl scheme.
.PP
It works by reading a pair composed by an IP address and an username
on STDIN and matching it against a configuration file.
.
.SH OPTIONS
.if !'po4a'hide' .TP 12
.if !'po4a'hide' .B \-d
Write debug info to stderr.
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B \-f file
Configuration 
.B file 
to load.
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B \-h
Display the binary help and command line syntax info using stderr.
.
.SH CONFIGURATION
.PP
The 
.B squid.conf 
configuration for the external ACL should be:
.if !'po4a'hide' .RS
.if !'po4a'hide' .B external_acl_type type-name %SRC %LOGIN /path/to/ext_file_userip_acl -f /path/to/config.file
.if !'po4a'hide' .RE
.PP
If the helper program finds a matching username/ip in the configuration file, it returns
.B OK
, otherwise it returns
.B ERR .
.PP
The configuration file format is as follows:
.if !'po4a'hide' .RS
.if !'po4a'hide' ip_addr[/netmask]	username|@group|ALL|NONE
.if !'po4a'hide' .RE
.PP
Where 
.B ip_addr 
is a dotted quad format IP address, the 
.B netmask
must be in dotted quad format too.
.PP
When the second parameter is prefixed with an 
.B "@"
, the program will lookup the
.B "/etc/group"
file entry for the specified username.
.PP
There are other two directives, 
.B ALL 
and 
.B NONE 
, which mean \(dqany user on this IP address may authenticate\(dq or \(dqno user on this IP address may authenticate\(dq.
