ext_file_userip_acl - Restrict users to certain IP addresses, using a text file backend.
ext_file_userip_acl [-dh] [-f file name ]
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.
The squid.conf configuration for the external ACL should be:
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:
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".
