Re: root password
 

Note: please check if you're not setting the suid bit on the entire busybox binary. (su might be a symlink to busybox)

If you are, then you will in trouble soon.

Suggestion: forget about everything said on this thread and just use "root" or "sudo gainroot".

Re: root password
 

i have rootsh installed. i was able to use sudo gainroot / root and both were working and still working.
the only extra thing done here is
i set the password for root
i set the password for user.
and executed this command as suggested:
chmod u+s /bin/su
pls let me know what sort of problems i may face?

Re: root password
 

You're absolutely right... :) It IS a symlink to busybox:
In my defense, I did say "I'm not sure this is something I would want to do"... :)

To clean up the mess run this:
And as said earlier as 'user' just type 'root' to become root (no password needed).

After this change You won't be able to use 'su -' anymore.

Re: root password
 

Thanks alot.
i executed as suggested by you :
su -
chmod u-s /bin/su

Now i will try doing ssh which i was suppose to do yesterday. i will check and let you know.
Thanks for being patient with my queries and helping me out. :)

Re: root password
 

As I said before, it is sudo asking for your user password, so you must have entered your user password, it was accepted then sudo is telling you you don't have permission to run /bin/su.

To fix this you need to edit your /etc/sudoers file, it is dangerous to edit this file manually because if you don't do it properly sudo will complain and stop working, instead it is advisable to edit this with the command visudo (which will verify any changes you make for correctness before saving the new file), unfortunately visudo defaults to using the "vi" editor which isn't the easiest for a noob (but I like it).

For the fix:
- Become root using the command "root"
- Run "visudo"
- Switch vi to insert mode by pressing "i"
- Add either "user ALL=(ALL) /bin/su" to enable that specific command with sudo or "user ALL=(ALL) ALL" to enable all commands with sudo, and add it to the top of the file.
- Switch vi back to command mode by pressing "Esc"
- Save and quit vi by typing ":wq"

Re: root password

is there any way to fix it?

Re: root password
 

please tell me how to set password for root or user.I mean to say if i type sudogainroot it should ask me the password i set.I saw it on UBUNTU but unable to do so on N900.

Re: root password
 

Instead of messing directly in /etc/sudoers You can create a file in /etc/sudoers.d with just the settings You need... ;)

Like this:
or this (same but for ALL commands):
or without password:
(Again, run 'root' before to become root)

Re: root password
 

Change to root:
Set password for user:
or root:

It still won't ask You for a password when You use 'sudo gainroot' or 'root' (which does the same thing. changes to root WITHOUT asking for a password). It's what the "rootsh" package is meant to do.

Re: root password
 

Here's a guide for getting "Ubuntu-like sudo behaviour":

Create the new sudo rule:
Set user password:
After this You can close the terminal and uninstall the rootsh package. Or just remove it using:
Close the terminal and open a new one or exit out of the root shell using 'exit' or Ctrl-D.

To become root now type (enter Your 'user' password):
(Doing it this way there is no need to run sudo before commands if You've switched to root first)

Or if You just want to run a single command as root type (enter Your 'user' password):
Oh, and Merry X-Mas BTW... :D
