Re: an already "gainrooted" xterm

I forgot a step. Run update-sudoers (as root) after creating the .sudoers file.

ok, now this looks interesting:

/etc/sudoers.d/01sudo changes break sudoers

I have no idea what "01sudo" is and I have undone any changes I made to it:

I removed that file to update and then put it back.

Re: an already "gainrooted" xterm

Editing the sudoers file is very difficult to use anything but VI. (I don't know what you use)

The actual recommended way is using "visudo".. I don't know if the N900 has that or not.

Essentially even wrong end of line characters can cause sudo to stop working.

Just some thoughts... in vi if you use ":set list" you can see the end of line characters... ^M == bad.

Re: an already "gainrooted" xterm

Just don't reboot, Bec, as you might need to reflash your system if you do. Copy a working 01sudo file (for example, from here: http://my.arava.co.il/~matan/770/n900/01sudo ) and run update-sudoers.

user ALL = NOPASSWD: /usr/bin/emelfm2
Then use Exec = /usr/bin/sudo /usr/bin/emelfm2
or Exec = osso-xterm "sudo emelfm2"

Now that^ can FUBAR your device if you don't know what you are doing. :eek:

For future reference: Use visudo instead of editing sudoers directly. visudo tells you if a line will **** up the entire sudo system when exiting the editor.

The simple addition of an extra space in a line while editing with a plain ol' text editor will screw things up...

Now for the best part...
sudo gainroot asks for a password...

For the first time I use it, no matter how many times I've tried to set one (always the same) it didn't seem to work...

Problem is that the usual password doesn't work...

Re: an already "gainrooted" xterm

It asks for user's password, not root password. Did you install openssh server? If so, ssh directly to root.

Re: an already "gainrooted" xterm

I've ssh-ited it... surprisingly it stopped asking for a password... awkward

As I do realize how close my ignorance brought me to a re-flash I'd apreaciate some details about visudo.

Thanks

Re: an already "gainrooted" xterm

visudo is an editor that checks the file has the corrext syntax for a sudoers file before overwriting the original.
