Ahh, I found where my confusion was... linuxconf apparently was in
control of the default gateway, and setting it with netcfg ( and
restarting networking, etc.) didn't matter a hill of beans to it
for some reason. I take it netcfg and linuxconf use different
config files? Anybody know which file(s) linuxconf uses for
networking stuff?  Or am I (again) way off base? I'd rather use an
editor, so I know what is really happening there.

Thanks-

It's some sort of bug...  At first we thought it was in the ide-scsi
code, but it behaves exactly the same with SCSI burners.  I'd like to
find the time to dig through the code and see if I can track anything
down, but I suspect it's going to be subtle.

I've never seen it mentioned, but it definitely does not work.  I can set
up 4 burners and burn to two of them, then the other two, but if I do
3 at a time it fails.  It's not a bandwidth issue, it fails if I have
two controllers in the machine with two drives hooked to each.

I haven't used 12 burners, we have 4 4x and 4 8x.  Mostly we're going for
less expensive drives and trying to run in parallel.  With start up and
fixating time added in, you'll probably be getting more like 7 to 8 minutes
for a full 700MB burn, instead of the 6 that a 12x rating would indicate.
But it's likely to be faster than what you'd get with a pure 10x burner
(which would have the same extra time requirements).

It should show you somewhere in the stderr output, what the
error was.

When I get this error it is most of the time a file which has changed
it's size while being backed up - or a "busy" file, like the
Windows swap file ( on a smb file system).

It can be of  concern since the backup was done with an
error.

save the stderr output to a file and look thru there.

like
tar cvf /dve/ht0 . 1> /tmp/tar1.log 2> /tmp/tar2.log &
tail -f  /tmp/tar2.log

Subject: [lug] Doh. Cannot start X
Reply-To: lug at lug.boulder.co.us

OK, I know this is a newbie type question. But...I've search the net
(web and news), searched the mailing list archives, and I have yet
to find a "good" answer to this. So...I'm hoping someone knows
what causes this, and what I can do to mitigate.
Up until today, I have been able to "startx" on my RH6.2 box using
my user account no prob. So...I was updating mysql, recompiling,
and everythings looking OK. I reboot. I re log in. I type "startx" and
I get:

Authentication failed - cannot start X server.
Perhaps you do not have console
ownership?_X11TransSocketUNIXConnect: Can't connect: errno =
111
giving up.
xinit: Connection refused (errno 111): unable to connect to X server
xinit: No such process (errno 3): Server error.

Now, WTF happened? I messed with some file perms in /var but
changed them back thinking that maybe something there caused
this to happen.
Right now, I can only do startx as root. Not funny :)

Confused, and needs some help/direction.

TIA,
-Anders.

What are the permissions on your X program?

	guin:jafo$ which X
	/usr/X11R6/bin/X
	guin:jafo$ ls -l /usr/X11R6/bin/X
	lrwxrwxrwx    1 root     root            8 Jun 27 22:51 /usr/X11R6/bin/X ->
Xwrapper*
	guin:jafo$ ls -l /usr/X11R6/bin/Xwrapper
	-rws--x--x    1 root     root         6260 Mar  6  2000
/usr/X11R6/bin/Xwrapper*
	guin:jafo$

Notice that Xwrapper is mode 4755, owned by root.  I'd guess that yours is
not.

Here's what I have on one of my machines.  It doesn't have the
"proposed-updates" stuff, but it does have the security stuff.

I had to go grab an SSH client for the Mac to get it in this e-mall!  :)

I haven't put a proper mirror site in this particular machine yet either.
'netselect' is nice for finding a good mirror site to use.

The other machine is off (my desktop machine in the other room), if you need
the other stuff, I can send that later...

# /etc/apt/sources.list
deb http://security.debian.org stable/updates main contrib non-free
deb http://http.us.debian.org/debian potato main contrib non-free
deb http://non-us.debian.org/ potato/non-US main contrib non-free

The order does matter in case someone forgets to roll the version number of
a package properly when one gets updated (rare, but it happens in the
"unstable" branch sometimes...)

That's the first thing that my script I run after KickStart building RH
servers does... rpm -e linuxconf!

That thing has more viral qualities than many so-called viruses!

I must admit, I rather appreciate when it's on the machine to help someone
who's new to Linux through an initial installation, though.

I guess that's the definition of a love/hate relationship?

sean already suggested checking permissions on xwrapper.  you might
also make sure that you don't have an extra IPC unix-domain socket
lying around; X creates one of these for running clients on the same
machine as the server.  it usually lives in /tmp somewhere:

   $ ls -ald /tmp/.X*
   -r--r--r--    1 root     tkil           11 Sep 24 09:14 /tmp/.X0-lock
   drwxrwxrwt    2 root     tkil         1024 Sep 24 09:14 /tmp/.X11-unix

it's a long shot, but this has been known to confuse later sessions,
if they didn't get removed properly.

I remember when it first came out, I tried it, changed one thing,
and it ended up messing up so many things, but it didn't change
any of the regular config files. I just re-installed. I dont know
what happened, but it does things you don't tell it to. Kinda like
MS. It thinks it knows whats best for my system. It's a nice idea,
but the implimentation of it ....

Ya thats the last time I use that thing.
