Please don't retype rules when posting to the list (I can tell from your typos 
that you have).   Copy and paste instead.   If we don't see *exactly* what is 
running on your machine, we can't offer accurate advice.

> Any idea why x server wont load?

Yes.   X needs to talk to itself over the loopback interface lo.

I suspect in fact that nothing which requires a network connection is going to 
work with the above ruleset (typos ignored), since you have no rule allowing 
replies in, for the packets which you do allow out....

I suggest you add some LOGging rules to your setup so that when things don't 
work, you can see what is trying to happen, and being blocked.

For example:

iptables -A OUTPUT -j LOG
iptables -A INPUT -j LOG

These will show you what sort of packets are trying to get out or in, just 
before they get DROPped by your default policy.

In order to solve the problem, I recommend allowing all packets to/from 
interface lo:

iptables -I INPUT -i lo -j ACCEPT
iptables -I OUTPUT -o lo -j ACCEPT

Regards,

Antony.

What does foo stand for. It is used everywhere. I understand its just a

it is used but I would still like to know what it means.

Depends a bit on the distro, but I can't think of any common app that would 
rewrite XF86Config *every* time you start X.

Perhaps you'd benefit from telling us the details?

1. What distro and version?

2. How do you start X? (startx, xdm, something else)?

3. What version of X? (At least on some distros, X 4.x.x uses a config file 
called XF86Config-4, not the older XF86Config used with X 3.x.x. Might you 
be editing the wrong file?)

4. What changes are you making (or trying to make)? Might you be making a 
change that does not work? And how are you making the changes -- editing 
XF86Config in vi, using xf86config, something else?

5. Exactly what do you mean by "it go back to the original"? Examples of 
what you *might* mean are:

         A. the changes in XF86Config do not show up in the way X starts.
         B. after starting X, you open XF86Config again, and the changes 
you made are lost.
         C. The same as B, plus the XF86Config file has an old timestamp, 
not a recent one.

In cases B and C, if you edit the XF86Config file, save it, close your 
editor, restart your editor, and open XF86Config again (without starting X 
in the meantime), do you see the changes you made?

If i may point out that XFre86-4.x.x "does" use XF86Config, it will use it as 
default "if" no XF86Config-4 is found.
I use XFree86-4.2.0 on one machine here and i "dont" have a -4 file.
It is documented and it was decided to make XFree86-4.x.x look for both files 
to make it backwards compatable.

Another handy hint is that XFree86-4.x.x now writes a complete log of every 
boot into /var/log called XFree86.0.log (if .0 is found then it will be .1) 
and so on.
You can see what config file is used in that log file + so much more than the 
old way of capturing its output at starttime.
(But i dont think i needed to tell Ray that) i just wanted to make a point of 
the "-4" thing.

The rest of the excelant stuff snipped.

Re: X

I already solved my problem. The thing was that I was writing on the
XF86Config instead of the XF86Config-4

X

[George Gensure,,,]

When I build X, in the execution of several key programs for 
installation, like xkbcomp, and in the execution of nearly all the base 
X utilities, like xdm, I receive a bus error.  Does anyone have any idea 
how to build to avoid this problem?  I'm building on an r5000 Indy.

I've never seen this kind of error before but the kernel you're using is
ancient, probably switching to a more recent one helps (2.2.16 and
2.4.0-test9 work fine for me). What version of glibc are you using? If
it is as old as your kernel you won't get anything to work.( I'm using
2.0.6-5lm here).

Oh.  Uh, any parts that I can help out on?  I appear to have a weekend
