I modified it to above and removed ExtData1 reference and it worked. I tried to set the xtics manually and change them according to Marco's reference, but the graph did not refect all the games so I modified the data file and added the date and the opponent and then modified the range to prohibit the line going below and keep everything in quadrant I. If anyone has a nicer way to make the graph look better, or format it using something else please help. I would like for our athletes to see what we need to work on the Goal Differential and not allow too many goals against us.

Dlink DWA192 Kernel Support Issue
by Stephen Morris 09 Feb '16

09 Feb '16

Hi, I have just upgraded my usb wireless adapter from a Dlink DWA182 which was not supported by the kernel, which I'm told never will be supported by the kernel, to a Dlink DWA192 which appears to be natively supported by the kernel. The issue I have is that the network interface only sees the 2.4GHz ssid it doesn't see the 5GHz ssid, is this intended functionality, inadvertent or is support for the 5GHz band not implemented yet? I'm currently using the 4.3.4-300 kernel. regards, Steve

Latest claws mail moves to message above deleted message instead of below
by stan 09 Feb '16

09 Feb '16

I sort messages in claws by date descending. So the newest messages are at the top. When I read, I start at the top, and process messages as I move down. Claws used to move to the message below the current message on delete, now it moves to the message above. So if I delete a message it now moves to a message that I have already seen instead of the message below the deleted message. It seems that this 'feature' was added in 3.13.1. * A hidden pref has been added, 'next_on_delete'. This controls the message selection when a message is deleted. A setting of '0' which cause the previous, older message to be selected, a setting of '1' will cause the next, newer message to be selected. I looked in ~/.claws-mail/clawsrc and I see the setting called next_on_delete. It was set to 0, so I set it to 1. It didn't make any difference. I tried 2 and -1 with no effect. Does anyone know what to do to get the previous behavior? I don't see a bugzilla for this, and a search at claws-mail.org doesn't turn up anything. Thanks, Stan

nvidia-304xx broken with new kernel
by David A. De Graaf 09 Feb '16

09 Feb '16

The latest two kernels and the nvidia-304xx module are incompatible. That is, the nvidia.ko module built by akmod-nvidia-304xx won't load. That means that my three machines with older nvidia video cards (one built into the mobo) are stuck running the old > kernel-4.2.8-300.fc23.x86_64 kernel-4.3.3-300.fc23.x86_64 kernel-4.3.3-301.fc23.x86_64 In the past, incompatibilities were resolved in about a week. This time, it's nearly a month. No new package of akmod-nvidia-304xx or kmod-nvidia-304xx has shown up at the rpmfusion-nonfree-updates[-testing] repo. The akmod-nvidia-340xx module on another machine that needs it runs fine. Does anyone have a clue when this older version of the nvidia module might be fixed? Here are the error messages with the newer kernel: Console error message when trying to run 'startxfce': (==) Using system config directory "/usr/share/X11/xorg.conf.d" modprobe: ERROR: could not insert 'nvidia': Unknown symbol in module, or unknown parameter (see dmesg) >From dmesg: ...

RE: iptables -
by J.Witvliet＠mindef.nl 09 Feb '16

09 Feb '16

Hi Bob, As many said before, due to the lack of info, will result in only partly helpful replies..... 1) Decent firewall's have all policies firmly to "DROP" (instead of the default "ACCEPT") 2) Assuming eth0 is your lan-device, (connected to 192.168.1.255/24) 3) Assuming eth1 is connected to your internet modem 4) before (!) allowing other traffic outside insert iptables -t filter -A FORWARD -i eth0 -o eth1 --source 192.168.1.17 -j DROP iptables -t filter -A FORWARD -I eth1 -o eth1 --destination 192.168.1.17 -j DROP 5) next allow other traffic to go outside Input- and output-chains are only for traffic originating from the box, or having the final destination on the box. Traffic passing through is handled by the FORWARD-rule. As I indicated in my top-line, this is very crude, iptables allows making self-defined sub-chains, and many other nice tricks, like timebased rules and so on.... -----Original Message----- From: users-bounces(a)lists.fedoraproject.org [mailto:users-bounces@lists.fedoraproject.org] On Behalf Of Mike Wright Sent: maandag 8 februari 2016 23:25 To: Community support for Fedora users Subject: Re: iptables - On 02/08/2016 02:10 PM, Bob Goodwin wrote: > > Can someone give me an example [for my router] of the iptables code > needed to prevent 192.168.1.17 from connecting to the internet while > keeping normal LAN access? Hi Bob, Decided lack of info to go on but this will accomplish that. If you just want the internet to be "non-existent" WRT 192.168.1.17 the easiest way is to DROP all traffic between them.

Sharing files between host and guest under KVM
by Patrick O'Callaghan 09 Feb '16

09 Feb '16

I've been using VirtualBox for several years with generally good results, but decided to try KVM as an alternative. I've converted a Windows VM from VBox to KVM format and it works well enough for my needs (it may even be faster), except that I can't see how to share files between the VM and my Fedora host. Clearly this could be done using Samba or NFS. Is there an easier way? In VBox it's all point-and-click so some guidance would be appreciated. poc

Wayland and Shutter

I seem to be the only person on this bug: https://bugzilla.redhat.com/show_bug.cgi?id=1299293 So, if you use shutter and Gnome, would you mind loading Gnome with Wayland and see if shutter works for you? It would be nice to know if it's me-specific or a general problem. -- -- Steve
