I need to enter recovery mode of my redhat box which is running remotely on a virtual machine.
I use RedHat 5 64-bit Enterprise Edition.
I am logged into the box using SSH. I can restart using the restart command but I need to know if I will be able to SSH to it, since I am using it remotely and cannot login through the UI.
The real problem is, I had done a
chown -R $USER / on the root directory.
I was trying this as a trial not realizing the consequences, to make something work, which somehow was not working even with the use of sudo.
I killed it mid way. But, because of this stupidity, I can't use sudo.
I have read that I can do something in rescue mode, but I don't understand how do I get into rescue mode remotely. I cannot reinstall linux, that is not a possible option.
Is there anyway I can get back my sudo permissions?
Doing this does not work as of now:
chown root:root /usr/bin/sudo chown: changing ownership of `/usr/bin/sudo': Operation not permitted sudo chown root:root /usr/bin/sudo sudo: must be setuid root
