NAME

doas.conf — doas configuration file

SYNOPSIS

DESCRIPTION

The doas(1) utility executes commands as other users according to the rules in the doas.conf configuration file.

The rules have the following format:

Rules consist of the following parts:

permit|deny

The action to be taken if this rule matches.

options

Options are:

nopass

The user is not required to enter a password.

keepenv

The user's environment is maintained. The default is to reset the environment, except for the variables DISPLAY, HOME, LOGNAME, MAIL, PATH, TERM, USER and USERNAME.

keepenv { [variable ...] }

In addition to the variables mentioned above, keep the space-separated specified variables.

identity

The username to match. Groups may be specified by prepending a colon (‘:’). Numeric IDs are also accepted.

as target

The target user the running user is allowed to run the command as. The default is all users.

cmd command

The command the user is allowed or denied to run. The default is all commands. Be advised that it's best to specify absolute paths. If a cmd is specified, only a restricted PATH will be searched.

args ...

Arguments to command. If specified, the command arguments provided by the user need to match for the command to be successful. Specifying args alone means that command should be run without any arguments.

The last matching rule determines the action taken.

Comments can be put anywhere in the file using a hash mark (‘#’), and extend to the end of the current line.

The following quoting rules apply:

• The text between a pair of double quotes (‘"’) is taken as is.
• The backslash character (‘\’) escapes the next character, including new line characters, outside comments; as a result, comments may not be extended over multiple lines.
• If quotes or backslashes are used in a word, it isn't considered a keyword.

EXAMPLES

The following example permits users in group wsrc to build ports, wheel to execute commands as any user while keeping the environment variables ENV, PS1, and SSH_AUTH_SOCK, permits tedu to run procmap as root without a password, and additionally permits root to run unrestricted commands as itself.

# Non-exhaustive list of variables needed to
# build release(8) and ports(7)
permit nopass keepenv { \
        FTPMODE PKG_CACHE PKG_PATH SM_PATH SSH_AUTH_SOCK \
        DESTDIR DISTDIR FETCH_CMD FLAVOR GROUP MAKE MAKECONF \
        MULTI_PACKAGES NOMAN OKAY_FILES OWNER PKG_DBDIR \
        PKG_DESTDIR PKG_TMPDIR PORTSDIR RELEASEDIR SHARED_ONLY \
        SUBPACKAGE WRKOBJDIR SUDO_PORT_V1 } :wsrc
permit nopass keepenv { ENV PS1 SSH_AUTH_SOCK } :wheel
permit nopass tedu as root cmd /usr/sbin/procmap
permit nopass keepenv root as root
