Sudo rules management examples

Sudo rules provide the system administrator a way to delegate privileges to certain users in order to perform commands either as root or as another user.

Creating a sudo rule

Create a sudo rule that will hold time change commands.

api.Command.sudorule_add("timechange")

Managing sudo commands

Sudo rules must be filled with sudo commands. Create one for date.

api.Command.sudocmd_add("/usr/bin/date")

Then, attach the sudo command to the sudo rule.

api.Command.sudorule_add_allow_command("timechange", sudocmd="/usr/bin/date")

Alternatively, groups of sudo commands can be created and attached to the rule in the same manner.

api.Command.sudocmd_add("/usr/bin/date")
api.Command.sudocmd_add("/usr/bin/timedatectl")
api.Command.sudocmd_add("/usr/sbin/hwclock")
api.Command.sudocmdgroup_add("timecmds")
api.Command.sudocmdgroup_add_member("timecmds", sudocmd="/usr/bin/date")
api.Command.sudocmdgroup_add_member("timecmds", sudocmd="/usr/bin/timedatectl")
api.Command.sudocmdgroup_add_member("timecmds", sudocmd="/usr/sbin/hwclock")
api.Command.sudorule_add_allow_command("timechange", sudocmdgroup="timecmds")

Commands can be denied as well. Deny the rm command to be run as sudo.

api.Command.sudocmd_add("/usr/bin/rm")
api.Command.sudorule_add_deny_command("timechange", sudocmd="/usr/bin/rm")

Adding users and hosts to sudo rules

Add the user bob to the previously created rule.

api.Command.sudorule_add_user("timechange", user="bob")

Restrict the rule to only be available for the client.ipa.test host.

api.Command.sudorule_add_host("timechange", host="client.ipa.test")

Setting “run as” for sudo rules

While sudo rules are run as root by default, a different “run as” can be configured, both for user and group rights.

api.Command.sudorule_add_runasuser("timechange", user="alice")

api.Command.sudorule_add_runasgroup("timechange", group="sysadmins")

Managing sudo options

Set a sudo option for the timechange sudo rule.

api.Command.sudorule_add_option("timechange", ipasudoopt="logfile='/var/log/timechange_log'")

Enabling and disabling sudo rule

Enable a sudo sule.

api.Command.sudorule_enable("timechange")

Disable a sudo sule.

api.Command.sudorule_disable("timechange")
