Depending on the operating system this mayinclude _rld*, dyld_*, ld_*, ldr_*, libpath, shlib_path, and others. You can grant all levels of access (to commands, systems, etc. Two disadvantages of the unix model are the increased security vulnerability and the corresponding management burden of maintaining root passwords on multiple machines. On aix(and linux systems without pam), the contents of /etc/environment arealso included. Parentheses may be used to group symbols together. If arguments are present, the string must be enclosed in double quotes ( ). For the other networks in csnets, the local machine s netmask will be used during matching updating sudoers. The reserved word all is a built-in alias that always causes a match to succeed. By default, the env_reset option is enabled. The command list is qualified with the passwd: directive, meaning that users must authenticate themselves each time sudo is invoked to run a command. Conf file # # format: # plugin plugin_name plugin_path plugin_options. Quest authentication services is well-suited for using administrative groups with sudo because it uses local pac data to look up group membership. D sudo will read each file in /etc/sudoers. This can be used to guard against printf-style format vulnerabilities in poorly-written programs. %opers kookaburra = (mysql) [runas_users_groups,%syslog] /usr/sbin/mysqladmin opers can run mysqladmin as the mysql user in any of that user s groups, as well as the syslog group. # the plugin_name corresponds to a global symbol in the plugin # that contains the plugin interface structure.

Means that the preceding symbol (or group of symbols) isoptional. It shows unchanged here because i d already done it. Note that changing the locale may affect how sudoers is interpreted. The following distributions of sudo have been tested by us on non-linux platforms and are known to work: sudo that unixadmins is a group and not a username. Notes on compiling from source ================================= the shell script rcconfigure found in this directory is a wrapper script that will invoke configure with the right arguments to enable the active directory extensions updating sudoers. These type of variables are removed from the environment before sudo evenbegins execution and, as such, it is not possible for sudo to preservethem. This can be used to implement support for the nonunix_group syntax described earlier. , /tmp), itis possible for a user to create the time stamp directory before sudo isrun. +secretaries all = printing, /usr/bin/adduser, /usr/bin/rmuserusers in the secretaries netgroup need to help manage the printers as well as add and remove users, so they are allowed to run those commands on all machines. Sudoers_locale locale to use when parsing the sudoers file, logging commands, and sending email. For example: /bin/ls [[alpha]]* note that a forward slash ( / ) will not be matched by wildcards used in the path name. Gnu make is sometimes installed separately as the gmake command. This default may be overridden via the passwd and nopasswd tags. Sl, rld, or loader) to see if ld_preload is supported. C the resulting makefile requires gnu make to be used to build sudo. So plugin options /etc/group local groups file /etc/netgroup list of network groups /var/log/sudo-io i/o log files /var/db/sudo directory containing time stamps for the sudoers security policy -i mode on aix and linux systems examples below are example sudoers entries.

This field is only present when logging via sudo front end will load. Don t despair if you are unfamiliar with ebnf; it is fairly simple, and the definitions below are annotated.

The use of groups with quest authentication services and active directory allows you to abstract individual user identities out of the unix hosts being managed and controlled in active directory along with all other user account information. The -g flag: sudo -g specifies that the chosen command should be run with a different primary group id. These arguments (if any) will be passed to the plugin s initialization function. Unlike sudoers requires authentication, it validates the invoking user s credentials, not the target user s (or root s) credentials. After the command completes, johns remains logged in as johns. This can be a security issue since it is not uncommon for a program to allow shell escapes, which lets a user bypass sudo s access control and logging. Ebnf also contains the following operators, which many readers will recognize from regular expressions. This is because the c library s fnmatch(3) function cannot resolve relative paths. Rather than just specifying %group kookaburra = (all) all you can now specify %domain\ users kookaburra = (all) all % domain users kookaburra = (all) all % domain [email protected] Hostname the name of the host sudo was run on.
