help Give users root access

**warpedmind** · 02-20-2003, 07:10 PM

After installing knoppix onto the harddrive (which went so smoothly, it was a beautiful thing),
I upgraded from KDE3.0 to KDE3.1 (which is also beautiful)

however befor upgrading I was able to be logged in as a user and then open
up konsole I would type

su then my password and I would have access to root and be able to run Xapps

After upgrading to KDE3.1 I no longer have that ability. I have to use

xhost +local:<username> and then I have access. but If i reboot I have to type it in
again.

I dont want to have to type that in EVERYTIME I want to have root enabled Xapps when I
restart the system, I want the system to do this at startup like it did before I got KDE3.1

Does anyone know what commands should put in to give any current and future user I create root access to the Xapps.

Also where should I put the commands.

thank you in advance for your help.

I had this problem a loooooong time ago when I broke X on a Mandrake6.5 box.

The fix was to create a file in /etc/ called X0.hosts containing one line:

localhost

The X server will automatically apply it in the manner of "xhost +localhost" each time the server starts.

Whether it is still the same now and on Debian, I don't know.

Nick
P.S. Note X0.hosts is a capital 'X' and a zero 0, not an 'oh'

I tried to create the X0.hosts file inside the /etc/ directory....nope it didnt work.

when I login and su to root I try to start an Xapp... in this case to keep it simple I use xeyes.

this is what happens

root@Sphinux:/home/luis# xeyes
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

Error: Can't open display: :0.0

the X0.hosts file inside the /etc/ directory only has the one line you said to put in.

any other suggestions? maybe its different in knoppix debian?

I don't know then... it worked 3 years ago

As to the

Error: Can't open display: :0.0

that can be fixed by setting the ENV $var

env DISPLAY=localhost:0

everything works just fine if I type in

xhost local:

just dont know how to make knoppix/debian using KDE3.1 do it automatically.

Just thought!!

To use the X0.hosts file, you need to have a localhost entry in /etc/hosts !

OK

Please walk me through what you mean about the /etc/hosts file.

this is what is inside my file

127.0.0.1 Sphinux localhost

# The following lines are desirable for IPv6 capable hosts
# (added automatically by netbase upgrade)

::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

what do I need to do?

**Nick** · 02-20-2003, 10:50 PM

127.0.0.1 localhost is right.

Also, do a:

#> man xhost

That will tell you more about X.

Nick

*EDIT* OK, I see the spec has changed. Try:

local

In the /etc/X0.hosts file instead.
