Chrony, NTP, and Firewalld -
by Bob Goodwin
I have two Fedora-21 computers set as time servers for chrony, this one
[box10] Which began as a new install and box7 which evolved from the
alpha version. In both the firewalld GUI Service > Workstation > NTP
show "checked." However I have to disable the firewall in box7 to allow
it to serve chrony and display in chronyc sources.
So it appears that the GUI is not telling the whole story, stuff is
happening that it doesn't cope with. I considered yum remove and
re-install firewalld but rejected that idea as probably causing more
problems. I guess that means fixing iptables from the command line, a
scary prospect!
Can anyone offer some very basic help doing that?

Window manager problems
by Tethys
I had an old machine running some ancient version of Fedora (13 or
something, I think). All was good. But obviously obsolete and probably
insecure. So I upgraded to Fedora 20 before Christmas. I typically use
fvwm. However, when I move windows, an image of the window in its
previous position remains. See the following screenshot:
http://pics.astradyne.co.uk/ref/150101--fvwm.png
Note that there is only one terminal open here. The rest are ghost
images. It doesn't do this if I use GNOME or KDE. I initially thought
that it might be an fvwm problem. But I can replicate it using icewm
as well. There are two ways to start the window manager - via the
session type dropdown box, or via a user script (~/.Xclients). Playing
around with a few options, I get the following results:
Starting from session dropdown:
fvwm - broken
icewm - working
KDE - working
GNOME - working
XFCE - working
Starting from ~/.Xclients:
fvwm - broken
icewm - broken
xfwm4 - broken
mutter - working
kwin - working
This is with Intel graphics:
macbeth:~# lspci | fgrep VGA
00:02.0 VGA compatible controller: Intel Corporation 4 Series Chipset
Integrated Graphics Controller (rev 03)
I tried compiling a new version of fvwm from source, but that showed
the same problem. icewm and xfwm4 are intriguing in that they're
broken from ~/.Xclients but working from the session dropdown. Any
ideas?

chrony lan -
by Bob Goodwin
If I block WAN connection to a server will it find a time reference on
the LAN? There's usually a workstation connected and getting it's clock
updated but it looks like the server is not? I haven't found the answer
in the man pages ... I was looking for a configuration setting perhaps.

f21 - dead.letter
by Robert Moskowitz
I just noticed that I am getting my logwatch email dropped off as
dead.letter under /root.
And that my personal cron rsync is also coming as dead.letter under
/home/rgm/
It seems that postfix is not running by default:
# systemctl status postfix
postfix.service - Postfix Mail Transport Agent
Loaded: loaded (/usr/lib/systemd/system/postfix.service; disabled)
Active: inactive (dead)
so I enabled and started postfix.
Is that what I need to do, and all I need to do?
I would like things to work tonight when cronie kicks off its jobs.

Firewalld and fail2ban on f21
by David Mehler
Hello,
Last time I tried this combination it was either f19 or f20 I was
unable to get it to work as firewalld was new. On f21 is anyone using
firewalld to manage their firewall and fail2ban to protect services
against bots?
Thanks.

Evolution 3.10.4 and Fedora 20
by Gregory P. Ennis
Everyone,
I have about 6 desktop's running F20 with evolution 3.10.4 that have had
problems related to the desktop gui 'freezing'. I can go to a terminal
interface by hitting <cntrl><alt>F2, and when I toggle back to the gui
it is still not usable. The screen is filled with the last object
displayed in this case it is always evolution that does not respond, and
I am unable to switch to anything else on the gui. All panels are
unaddressable.
At first I thought the problem was gpaste so I removed it on a test
desktop. The symptoms appeared less often but were still present. It
seems to hang with evolution.
Has anyone else had this problem? Can anyone help me debug this.
Thank you for your help.

suggestions for setting up a cluster in Fedora/CentOS
by Ranjan Maitra
Hello,
I have my hands on five slightly older (circa 2009-top-of-the-line) dual quad-cores, one of them has 16GB memory, the others have 8GB. All of them are otherwise identical. I want to try my hand at making a cluster out of them using Fedora 21 or CentOS 7. Are there any comprehensive documents someone could point me to? I am not sure what sort of cluster (ROCKs/Beowulf, etc) to set up, and I am also looking at this as a learning experience, so any suggestions in this regard would also be very helpful.
Many thanks and best wishes,
Ranjan
