Run command with sudo by default
I need a linux user (lets call him "bob") who is allowed to run a list of commands which require root privileges. So let him be required to run /sbin/firstcommand
and /sbin/secondcommand
(which are part of the infamous bob-daemon¹) as root, as in sudo firstcommand
. Without having to input a password.
This is what I've done to /etc/sudoers
so far:
Cmnd_Alias BOBCOMMANDS = /sbin/firstcommand, /sbin/secondcommand
bob ALL=(root) NOPASSWD:BOBCOMMANDS
This leads to bob$ sudo firstcommand
and bob$ sudo secondcommand
successfully be run as root, but leaves no way to run i.e. bob$ sudo mount ... ...
, even with providing a password, which feels perfect to me.
Now, I want the aforementioned bob-daemon¹ to run as user bob
rather than root
, because it only needs those privileges for the BOBCOMMANDS
. In fact, whenever the bob$ firstcommand
is issued, I want bob$ sudo firstcommand
to be executed.
Looked to me like an alias could fix this: bob$ alias firstcommand="sudo firstcommand"; alias secondcommand="sudo secondcommand"
actually worked, but I failed to make the aliases persistent without bob having a home directory.
The last thing I should mention is that this should be easily deployable to multiple machines, so I would prefer not to touch linux' existing system files, apart from having to create bob and changing sudoers
.
Any solutions?

If this is for a daemon, the standard way of doing things is to put something like this in the init script file:
USER=bob
...
su -c '/command/to/start/actual/daemon' "$USER"
In the script file that should be run as bob
, just put sudo
in front of the pertinent commands.
Also, make sure you read this about enabling alias expansion in non-interactive Bash shells (e.g. the ones started by a script or daemon).
Actually, the daemon handles user switching itself - started up as root, it does some bootstraps before forking and continuing to run asbob
. Plus, I did not create the daemon and would like to avoid patching it for the sake of updatability …
