I have been looking at the new Fedora firewall 'firewalld' and the
'firewall-cmd' command. I'm currently running F17 on a PC with an F18
virtual machine, and have been trying to understand firewalld prior to
upgrading to Fedora 19.
The PC has a modified iptables. So I have been trying to see how to
incorporate the changes into the new firewalld. I suspect I will need to
use the 'firewall-cmd --direct' option to add the iptables rules (as I
see no other way of specifying on the rules source/destination addresses
However, 'firewall-cmd' offers both the '--get-chains' and '--get-rules'
options, but these both require specifying which table is to be used.
How do I know what the tables are? There is no '--get-tables' option.
I can run 'cat /proc/net/ip_tables_names' and this lists the standard
iptables tables (nat ,mangle, filter). But if I use these names with
'firweall-cmd' all I get is a blank line displayed. E.g.
firewall-cmd --direct --get-chains ipv4 nat
The same occurs with all the table names.
So, my question is this, is 'firewall-cmd' working correctly and simply
stating that none of the tables have any chains (and so no rules)?
Secondly, how do I find out what tables are defined for firewalld?

When I try to print anything out, I get no printout. Even a test page does not come out. But no indication of trouble shows up on the monitor, and no indication of trouble on the printer's display. I did download and install the driver. cups gives no hint of trouble that I recognize. If I restart the system and boot up with Windows 7 home, I do get printouts.
The printer is a Xerox WorkCentre 6015ni, I'm using Fedora-18, 64-bit, and the printer is connected to the system via usb bus. This is a stand-alone home desktop.
I'm neither trained nor experienced in sys. admin. I've exhausted the help I can get from the printer's manual (media and web site). Any help you can give will be appreciated.
Does anyone have any experience with F18 on a Dell XPS13 with the FHD
1080p display? What does this Full High-Definition 1080p mean
anyway? I guess my question is: is this the real resolution or some
virtual resolution not obtained via linux.
I am interested in this because it claims to have a 1080 vertical
resolution (not sure if this is accurate) in an Ultrabook.
Note that Dell sells this with Ubuntu 12.04 LTS (for a price more than
with MS Windoze).

fedup changed the mail setup, and forget where Thunderbird's check-box
is to fix it.
I'm just curious as to how to fedup when F19 comes out; I am aware that
the command is
however, this is the beta as opposed to F18. Of course, F18 is available
to boot into, and I guess users boot into that to use the command above.
I suppose I answered my own question.
Using Fedora 18, KDE 4.10.2 on x86_64 laptop with kernel 3.8.11-200
and nvidia proprietary drivers.
I have two hard disk. One SSD with / and swap and one hybrid with /home.
Recently, I remarked extremely long times (>60 s) to open some
programs like firefox or dolphin, the latter being the most critical.
I suspect disk access to slow down the machine as this happens when
the processor is nearly idle.
What can I check? Can I check the hard disks, how? Could it be something else?
Thanks for help,
How do I reset my desktop back to what was there on a fresh install, or
am I better off creating a new home directory and simply moving my
"known" files back?
When I log in the screen flashes the icons (other accounts are fine) and
the CPU goes to 100% with the "tracker-extract" process

The pythonscript in the link does work.
I figured could make a .service file for it.

I don't/can't upgrade the machine outright. Too many issues, but I
can't seem to get my mail folders back or my accounts to sync to the pop
server if I do a restore via the menu. Is the format different?
How do I make this quantum leap?
I've been enjoying my 'new' (It's actually a bit old, being based in the
original AMD Brazos platform, z01 CPU, but still, dual-core and updated to
8GB RAM, purchased late 2012 and only having had time to play with it
The good news: Fedora boots fine and runs smoothly, BUT!...
1. The Gnome 3.x "hitting the top-left corner" system works and seems
designed with a mouse in mind, NOT touch. If I touch with the finger in the
upper left corner of the screen, 99.1% of the time (rough estimate ;) ....
NOTHING HAPPENS. That surely is because the "focus point"of the "hit" is
too narrow for a finger. In other words, it's expecting the mouse pointer
to be at 0x0 (or 1x1) pixel coordinate for a splt second before invoking
the gnome screens. With a finger hit, surely one fat finger translates to
coordinates 0-40 x to 0-40y.
It doesn't matter if I just position the finger in the corner, or if I try
to emulate the mouse action of doing a small travel with the finger and
"hitting" the corner. It only works on about 1 in every 20 tries.
So, how to fix this? how to make the "invocation area" bigger?
2. The unit comes with 3 sensor keys (virtual buttons drawn over the right
edge of the touch screen), that provide the following functions:
a. O-Easy (on Windows, this calls a custom MSI app that allows you to,
among other things, easy one-touch enable-disable of several tablet
components, ie WiFi, Bluetooth, GPS, cameras, etc). Before OS loads,
"O-easy" is mapped in the BIOS to the ENTER key, which together with the
volume up/down buttons on the side (mapped to cursor up/down) allow
navigating the Win7 boot menus without a keyboard and before the OS loads.
b. Home (used to minimize everything and get a look at the desktop, pressd
again, maximized apps return)
c. Hang. This simulates a Ctrl-Alt-Del. Used with win7, it's very handy to
invoke the Win7 task manager when a misbehaving app needs to be killed.
Well, on Fedora 'virtual keys' (a) and (b) do nothing, but (c) is the
worrying one as it sends Fedora on the awful standard Ctrl-Alt-Del "system
is shutting down in 60 secs..." dialog unles you cancel it.
I've been reading complaints about this default Ctrl-Alt-Del behaviour in
Linux since at least 2005... Isn't it time to change the dialog that AT
LEAST lets the user choose between many options, one of them being
"shutdown/reboot and another Start Task Manager?". It would be a great step
forward on the usability angle, specially for people coming from Windows.
(and not to mention on this table when you can simply invoke a shumtdown if
you're not paying much attention and tap into the Hang virtual button with
the corner of your hand while grabbing the tablet...
ANY IDEAS of how to fix/improve any of the points raised above is of course
1. I can do everything I used to do with a netbook, with a tablet.
2. I can run Virtualbox!. Try VBox on a ARM/Android based *TOY*
Final question: is F18/F19 SSD aware, or is there any manual tweak I must
take into account? (wrt flash device life, filesystem used (ext2 to
minimize writes, perhaps?)
PS: Tablet is a MSI WIndpad 110W, AMD Brazos z01. Still available in
Canada* (it was also in Amazon.com until December '12, that's when I bought
it, as it was the only non-Intel, x86 tablet that provided the best
price/performance -$450-550 and expandability -up to 8GB ram unlike its
only competitor at the time the Acer Iconia Tab W500).
