Hello all,

On my single-user redhat 7.1 machine I decided to change my hostname directly in the /etc/sysconfig/network file from localhost.localdomain to whatever.whatnot.dingleberry (just an example). I left the localhost.localdomain entry in /etc/hosts alone.

All was fine except for two anomalies that I don't get:

The sudo command was suddenly not asking for a password when I would run it as an authorized user (still listed in the sudoers file). When I changed my hostname back to localhost.localdomain sudo began properly asking me for my password again.

So what would cause that?

Secondly, if I would su - to root and try to run something that requires X I would get an access denied error for the DISPLAY that would require me to run xhost + . I don't think all X apps were giving me this, but linuxconf was for sure. Changing back to localhost.localdomain did not fix this. So I have 2 questions:

What caused this?
How do you make changes to your xhost access list permanent so I can stop typing xhost + ?

Thanks.

you changed hostname properly
you need to add entry to your /etc/hosts
su never asks for pass if you are root

--don't use linuxconf, (it causes more troubles, than does good)

Would I need to add my new hostname to /etc/hosts if I already have it listed in my zone records in my DNS server?

Also, I was not root already when I used sudo or su -.

And I also don't usually use linuxconf because I agree it's a pain sometimes. I was just using it as an example of an X app that wouldn't launch from terminal.

Any more ideas anyone?

Thanks.

Bret
