Blank Screen- 12 inch laptop
by Tracy12
Hi,
In my new Acer Travel Mate laptop the F7 installation did not work at all,
then I started the F6 installation and it went pretty well, the installation
was successful and there was no driver issue at all as in F7
I got a dual boot other OS is window,
Even though it went allright, After the second restart (after selecting the
OS option out of windows and fedora dual boot) doesnt matter windows or
Fedora it gives a blank screen.
My laptop got a smaller screen 12 inch,
Is this something to do with the screen resolution, should I have to give a
different kernel parameter.
What exactly this problem is , How to overcome this.
Thanks

A near realtime fs mirror application (for backup, written in Python, by Linux inotify)
by Roc Zhou
Hello:
Recently I started an open source project "cutils" on the sourceforge:
http://sourceforge.net/projects/crablfs/
The document can be found at:
http://crablfs.sourceforge.net/#ru_data_man
This project's mirrord/fs_mirror tool is a near realtime file system
mirroring application across 2 or more hosts, something like MySQL's
replication, but it's for the file system especially with a great amount
of small files, such as the php scripts and images of a website or the
(vitual) websites.
There are several ways to use this tool. The simplest is to mirror a
host's file system to another host for backup, and use the rotate
function(in the future version) or rotate scripts to get a daily or
hourly snapshot with the hard link.
Or futhur more, you can use it this way:
This graph should be displayed with monospaced fonts:
+----------+
| worker | -[mirrord] -----------\
+----------+ |
...... |
|
+----------+ |
| worker | -[mirrord] -----------\
+----------+ |
V
[fs_mirror]
|
+----------+ +----------+
| worker | -[mirrord] ---> | backup |
+----------+ +----------+
| |
[take_over] |
| |
V |
+----------+ |
| rescue | <------------------- NFS
+----------+
This is the multi to one backup, which is cost efficient. If one of the
worker hosts fails, you can subsitute the failed worker with the rescue
host, with the aid of any high available method, such as heartbeat
project. By this way, you can use 1 or 2 hosts to support the HA of more
than 3 servers.
Or you can also use it as an IDS(Intrusion Detection System) like a
realtime "tripware", or you can make a mirror chain that a host B mirrors
from A and be mirrored by C, etc ... I will also try to research a way
to use it as a distributed implemetation with one write and multi-read
model.
mirrord/fs_mirror makes use of inotify, which is a function afforded by
the recent Linux (from 2.6.12). It is a counterpart of FAM, since Linux
FAM has stopped so long.
Now it works for me, on a RHEL4 system and the LFS 6.2, I hope this tool
can be useful to you too.
Thanks.

Hi Tom,
you don't mention *how* (using yum, pup etc) you tried to update but
I'll confirm that my x86_64 system has had trouble updating for a day or
so, too.
I usually update when pup applet tells me there are updates available.
Occasionally, however, something goes amiss and pup seems to spend
forever fetching information on packages to be updated. It may load
300-500M of metadata(?) -- and at the end of it inform me that update
cannot be done for one reason or another. This time the problem was:
"failure: repodata/comps-f7.xml from updates:
[Errno 256] No more mirrors to try"
IMHO, it is extremely annoying to wait for an hour or more - only to be
told that update fails. Now I know that if the names of the packages to
be updates don't appear in a couple of minutes, the update *will* fail.
My solution is to to go CLI and 'yum update'. It worked this time, too.
Regards,
Antti

Email attachment.dat
by Simon Slater
G'day again
This may be a ver basic or even stupid question, but I'll ask anyway
(if I show my ignorance, hopefully I can increase in knowledge). Some
emails received have an attachment called attachment.dat. What is this
for and what is in it? I do not open attachments unless I know who they
are from & what they are for.

can't get Xnest to work against Fedora 7
by Hugh Caley
I have installed xorg-x11-server-Xnest-1.3.0.0-9.fc7 on my Fedora 7
desktop, but I cannot get it to work against two other Fedora 7 boxes.
I have used gdmsetup to make sure that xdmcp and remote connections are
enabled. I can make connections to RHEL 4 machines with no problem.
It looks like the connection is in some kind of loop. I never get
beyond the gray screen, but it blinks every second or so.
Used the following command line:
Xnest :8 -geometry 1024x768 -query hughc-virt
/var/log/messages on one of the target machine shows the following:

Easy Compiz keyboard shortcut question.
by Naoki
In regular gnome I can assign the "F" keys to the desktops, thereby
making my switching between them as easy as hitting F1 for desktop #1,
and so on up through my eight desktops.
In Compiz however I cannot seem to find anywhere to define this
behavior, having instead to slide between all of them or manually rotate
an octagon around to find my place.
At least I worked out how to get eight faces..
Any help from the group?

iptables: drop or reject?
by Ashley M. Kirchner
To drop or not to drop, that is the question. If there's a server
out there sending spam e-mail, and I use iptables to block it, is it
best to simply drop the packet, or should I do a '--reject-with
icmp-host-unreachable' (or 'icmp-port-unreachable') or just a 'tcp-reset'?
Basically, if I just drop the packet, the server in question would
simply continue to send stuff, wouldn't it? As far as it knows, its
spam reached the destination, whereas if I send something back, it might
actually acknowledge and stop? Yes? No?

As F8 is just around the corner, is there a preview of the F8 FAQ that
we can make suggestions on?
