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.

Configuration file to load.
Display the binary help and command line syntax info using stderr.


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
