SYNOPSIS

ugidfw add subject [not] [uid uid] [gid gid] object [not] [uid uid] [gid gid] mode arswxn ugidfw list ugidfw set rulenum subject [not] [uid uid] [gid gid] object [not] [uid uid] [gid gid] mode arswxn ugidfw remove rulenum

DESCRIPTION

The ugidfw utility provides an ipfw 8 -like interface to manage access to file system objects by UID and GID, supported by the mac_bsdextended(4) mac(9) policy.

The arguments are as follows:

add Add a new ugidfw rule.
add subject [not] [uid uid] [gid gid] object [not] [uid uid] [gid gid] mode arswxn
Add a new rule, automatically selecting the rule number. See the description of set for syntax information.
list Produces a list of all the current ugidfw rules in the system.
set rulenum subject [not] [uid uid] [gid gid] object [not] [uid uid] [gid gid] mode arswxn
Add a new rule or modify an existing rule. The arguments are as follows:
rulenum Rule number. Entries with a lower rule number are applied first; placing the most frequently-matched rules at the beginning of the list (i.e., lower-numbered) will yield a slight performance increase.
subject [not] [uid uid] [gid gid]
Subjects performing an operation must match (or, if not is specified, must not match) the user and group specified by uid and/or gid for the rule to be applied.
object [not] [uid uid] [gid gid]
Objects must be owned by (or, if not is specified, must not be owned by) the user and/or group specified by uid and/or gid for the rule to be applied.
mode arswxn Similar to chmod(1), each character represents an access mode. If the rule applies, the specified access permissions are enforced for the object. When a character is specified in the rule, the rule will allow for the operation. Conversely, not including it will cause the operation to be denied. The definitions of each character are as follows:

a administrative operations
r read access
s access to file attributes
w write access
x execute access
n none
remove rulenum
Disable and remove the rule with the specified rule number.
