No sure why you need SUDO if you are already ROOT on your router - SUDO switches temporary to ROOT if you are NOT superuser...

admin@RT-AC87U:/tmp/home/root# opkg list | grep sudo

sudo - 1.8.14p3-1 - Sudo (su "do") allows a system administrator to delegate authority to give certain users (or groups of users) the ability to run some (or all) commands as root or another user while providing an audit trail of the commands and their arguments.

As I mentioned, I need it for personal reasons. Got tons of bash scripts I copy between my servers, most of them contain sudo in aliases. I don't want to redact 20 files, just to make it work.

That makes no sense. Not having sudo on the router won't effect bash scripts running on other servers.

Or do you mean your bash scripts copy files between servers? In which case the error message suggests that you don't have a user called "root" which is normally true. The "root" user is normally called "admin" in asuswrt, but your output suggests you have called it "me".

and? how can I add root user to the sistem? Sudo wont work without it.

The router is designed to be a single-user machine. (Nearly) everything runs as the "root" account. That's why there is no useradd, userdel, usermod, groupadd, groupdel, etc.

Try this:

Go to Administration > System and change Router Login Name to "root".

Try it yourself. Administration panel won't let you change it to root.

Try it yourself.

No thanks.

All I can suggest is that you replace the sudo binary with a soft link to /bin/true That way the command will appear to work even though it doesn't actually do anything.

Like this idea. Thank you! Gonna try tomorrow.

or use sed.

sed 's/sudo //g' oldfile > newfile


The symlink of sudo to /bin/false seems much easier but I dunno enough to know if there would be potential problems.

Or just make a simple script called sudo that just executes the parameter list.

Symlink to /bin/sh?

Symlink to /bin/sh?

Even better Only thing I'm not sure of with either method is that the environment gets passed correctly.

Oh yeah, I forgot about passing the parameters, doh! It wouldn't be much use without them.
