SUDO not working for rehash command.

Sopalajo de Arrierez

If I SSH log with my unprivileged user:

[luis@pfSense-ThreepWood ~]$ sudo rehash
sudo: rehash: command not found
[luis@pfSense-ThreepWood ~]$ sudo -s
[root@pfSense-ThreepWood /home/luis]# rehash
bash: rehash: command not found

But if I SSH log as "admin":

[2.3-BETA][admin@pfSense-ThreepWood.localdomain]/root: rehash
[2.3-BETA][admin@pfSense-ThreepWood.localdomain]/root:

No problem at all.

Why is this happening?
Is there any limitation with the sudo command on pfSense?

Note that I am using pfSense 2.3Beta. I don't know if this could cause the problem.

sudo does not exist … it isn't included in pfsense
neither is bash

its you own choice ofcourse to mess with adding additional packages ...

@heper:

But this is what I get when searching into the package installer:

[2.3-BETA][admin@pfSense-ThreepWood.localdomain]/root: pkg search sudo
pfSense-pkg-sudo-0.2.9         pfSense package sudo
sudo-1.8.15                    Allow others to run commands as root

@heper:

neither is bash

Same case:

[2.3-BETA][admin@pfSense-ThreepWood.localdomain]/root: pkg search bash
bash-4.3.42_1                  The GNU Project's Bourne Again SHell

Maybe I have messed something on the repos file? I don't even remember where it is, due to I am new to pfSense and FreeBSD.

How can I tell my installed Bash and SUDO packages are or not pfSense official ones?
I think I installed them via "pkg install". I am nearly sure the only package from official FreeBSD repos installed until now is "Nano Editor".

You changed your shell to bash. rehash doesn't exist in bash.

For the benefit of future readers, there is a sudo package in the pfSense packages list - you install that from the webGUI and then you get the sudo binaries and a webGUI interface to configure sudo settings (which I find are fine in their default state as they come with the pfSense package).

So that means there is no need to rehash when my shell is Bash? Or maybe should I use another method, like rebooting?

There is no need to rehash when using bash.

I was supposing it.
Thanks you.
