I just fired up vncserver on my test box (currently running FC5) and
then started a vnc session to it from my FC4 box. Both systems have a
default gnome desktop with all updates applied. The monitor on the FC5
box is still in power save mode but the vnc session is behaving normally.
My expectation is that, if I wait a little while, the graphical
screensaver will "blank" (power on but hidden by the screensaver) the
remote desktop within the vnc window. Funny thing is, when I was using
vnc for remote access to my home network I was looking for a way to turn
even this off. I didn't want the screensaver for the vnc desktop
chewing up bandwidth by drawing pretty pictures.
The vnc installation is completely "default." My user vnc configuration
is pretty trivial:
# cat ~dave/.vnc/xstartup
#!/bin/sh
# Uncomment the following two lines for normal desktop:
unset SESSION_MANAGER
exec /etc/X11/xinit/xinitrc
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
gnome-session

Dave

Not to be funny and definitely not to start any kind of a gnome vs. KDE
flame war but I don't see VNC behaving like this with gnome. This
includes even having the "screensaver" kick-in after the set inactivity
period on the VNC desktop. I think both systems were running CentOS 4
(gnome, x.org) at the time. Just pointing out that this behavior *may*
be peculiar to VNC interacting with KDE.

Dave

This behaviour does not kick in when the screensaver starts up but
only when the screensaver goes off the screen when the power save
kicks in later -(in my systems).
I would be interested to know if you still get normal behaviour if you
wait until the screen is in powersave (not just with the screensaver
running visibly) with the operating system different from Fedora and
with gnome - this would certainly point at kde/vnc interaction of some
kind.
Hopefully more information can be obtained and a solution found.

Thanks - though I have seen postings elsewhere saying that it is
possible to use
vbetool dpms on
or
vbetool dpms off
See "man vbetool"
Apparently xset sometimes does not use the dpms system even though X
is supposed to - maybe this is why the unexpected behaviour occurs
after you have used those commands?
I understand that vbetool runs bios commands so might not have the
unexpected behaviour - it will be interesting to see any further
replies on this - and maybe other suggestions for workarounds?

NVIDIA GeForce FX5200 Linux Driver
by Erich Carlson
I put a new NVIDIA GeForce FX5200 128meg AGP 8X video card in one of my
systems running Fedora Core 5. I use the NVIDIA drivers that come with
Fedora.
Occasionally the screen will freeze, not very often, maybe once a week,
but am thinking it's the driver.
Does anyone have any knowledge of this condition with NVIDIA?
Is there a better NVIDIA repository that is compatible with Fedora Core
5?
I've done extensive debugging on all the other hardware components and
can't find the problem.

VNC problem - now more understood - but a solution?
by Mike C
Some time ago I noticed (in fact pre-FC4 !) that when I used VNC to
connect via an ssh tunnel into a remote computer that sometimes the
screen on my local machine was constantly repainting, and the
screensaver from the remote machine was loading up almost before I
could enter any mouse movements.
This has continued to happen but not every time, and since this was an
intermittent behaviour, I was puzzled by this mis-behaviour until now.
A short time ago I was testing vnc from this computer to one on the
other side of this same room, and noticed that this constant screen
re-painting was happening.... but then I also noticed that the other
computer was in fact in monitor power saving mode - and its screen was
blank.
So I walked across and waggled the mouse on the remote computer so
that its screen came alive - and lo and behold vnc started working
normally again!! The screen was not repainting and just as if the
remote machine was on my local desktop - exactly as vnc should behave.
So now I know ! VNC works fine when both computers have their
monitor in normal mode.... but once the remote monitor goes into
powersave then VNC misbehaves!
So the questions are:
1) Can I do something to wake up the power on the remote monitor once
I have ssh'ed in?
2) If not then can I still run VNC to look at the remote screen but
not have the constant irritation of the local screen display
attempting to put the screensaver back?
By the way both machines are running fully up to date FC5 with KDE desktop.
I hope someone knows the answer(s)?
Thanks

postix, cyrus imap and online backup
by Boris Glawe
Hello,
we're using postfix and cyrus imap on the same machine for internal
mail. Mail delivered by smtp to the machine is locally forwarded to the
imap server.
Currently all mail is handled by a domain provider. We fetch our
(external) mails via POP3 from the provider's server.
We'd like to extend the usage of this mailsystem in a way, that it will
1.) send all external mail,
2.) receive all external mail
*and*
3.) do an online backup of all mails that have been transferred.
1.) is easy to solve.
2.) What's the best solution here?
- we could forward mails from our domain provider to our
postfix machine. What happens if that machine isn't online
for a few days? Is there a solution that the mail is
regularly being fetched (every 5 minutes) from the
provider's server?
- what else do you suggest?
3.) The backup can of course be done by syncing the imapd's directory
regularly to another machine. Problem is that the backuped data
structure is an cyrus specific data stucture that can hardly be used to
restore lost mails. We'd like to have a solution that makes it easy to
restore lost mails and - if possible - is an online backup solution.
That means each mail the is delivered or received will automatically be
backuped while it's being handled.
Thanks for any suggestions.
If you have suggestions to use a different software environment for mail
delivery, please tell me.
Thanks and greets
Boris

Moving users and their home dirs to new server
by James Pifer
I'm building a new server to take the place of another, which has a few
user accounts, mostly for mail. For most of the box and it's services
I'm just re-setting up the new services, like DNS and DHCP. What's the
easiest way to move the users and their home directories so I don't have
to recreate them, they're passwords stay the same, etc? Is it as easy as
copying the files (while retaining permissions) and then copying the
relevant parts of /etc/passwd?
Thanks,
James
